This is your NEW
workout "partner".
A total of 265 pounds
sits a little over 20 inches above you. This is the starting block.
In 16.25 seconds, you will have lifted every one of those pounds
off the block, lowered the barbell to within 0.5 inches of your
sternum, raised it back up and then repeated this process 6 times.
When you lowered the barbell, your chest muscles lengthened. When
you raised it, they shortened. Lower and lengthen, raise and shorten,
and repeat…6 times.
Six isn't where this
story ends. A new workout partner gives you some assistance so
that you can squeeze out another 2 repetitions, for a total of
8. Upon returning the barbell to the starting block you rest for
60 seconds to allow the blood vessels in your tired muscles to
dilate and blood to rush in. This is the first set of several
that you will perform for your chest.
With the completion
of each one, more blood accumulates in the muscles, causing them
to swell in volume and vascularity. This is the "pump".
Somewhere along the way, an incompletely understood mechanism
is stimulated inside your muscle cells resulting in a surge in
myofibrillar protein synthesis that peaks within 24-48 hours of
your workout. If all goes well, when the surge subsides, you will
have managed to edge your physique a little closer to muscular
perfection.
Your new workout partner
didn't only help you with your first set. The assistance spanned
the entire workout, adding an average of 1.5 reps -approximately
4 seconds-to each set. Those seconds added up to make a major
biochemical impact: Thanks to your partner you were able to stimulate
more vasodilation, volumization and gains in muscle mass, strength
and power. To boot, you burned more calories, thereby protecting
yourself from body fat, the scourge of muscle shape and definition.
Your new workout partner
it isn't a human being, nor is it a machine. It is a breakthrough
dietary supplement that costs a mere dollar per serving and is
produced by a morally scrupulous company located at the highest
end of the quality spectrum. The company is Beverly International
Nutrition and the supplement is CREATINE SELECT™, with a
newly improved formula that is the strongest it has ever been.
New and Stronger CREATINE SELECT™
The new CREATINE SELECT™
formula was designed to prevent premature muscle fatigue caused
by two by-products of energy metabolism known to scientists as
"H+" and "Pi". Acting in combination, these
incomprehensibly small substances begin reducing the force, shortening
velocity and power of your muscles (the most common signs of muscle
fatigue during high-intensity exercise) the moment you leave the
starting block of your first set. And they don't leave you alone
until you finish your last.
Premature muscle fatigue
is a big deal. It does more than impair your performance. It also
affects the gains you realize --or fail to realize-- in the hours
and days that follow your workout. Consider the 265-pound bench
press described above. To lift a load this heavy, your chest muscles
must generate so much force that they actually squeeze their own
blood vessels shut, much like a vice applied to a garden hose.
This means that as
you raise and lower the barbell they are essentially holding their
breath. When the set comes to an end they "gasp" for
air: The blood vessels open up (vasodilation) even wider than
usual so as to allow oxygen-carrying blood to rush in. This is
known as "reactive hyperemia". Over the course of multiple
sets it causes your muscles and the blood vessels supplying them
to become pumped with blood. And we all know how strongly the
pump is connected with gains.
The longer your muscles
lift the same load while "holding their breath", the
more intense will be the reactive hyperemic response at the end
of the set, and the more gains in muscle mass, strength and power
you can potentially stimulate. If you can lift an even heavier
load, then that's even better. This is why protecting yourself
from premature muscle fatigue is so important if you want to improve
your physique and performance as quickly as absolutely possible.
Your Exclusive Defense Against Premature Muscle
Fatigue
New CREATINE SELECT™
helps defend your muscles against H+, Pi and other potential causes
of premature muscle fatigue. With these substances out of the
way, your muscles are able to generate more force and sustaining
higher shortening velocities and power outputs. In turn, this
encourages more intense reactive hyperemic responses following
every set and otherwise enhances your ability to stimulate gains
in muscle mass, strength and power, every single time you workout.
A human workout partner
pulls up on the barbell during a set to help you squeeze out an
additional 1 or 2 reps ("forced reps"). In so doing,
he or she actually lightens the load. This is no different than
if you pulled weight off the barbell yourself before resuming
the set ("drop set"). CREATINE SELECT™, in contrast,
contains ingredients that have been proven to help you lift the
same load for longer (more reps), or an even heavier one. This
is an important distinction, one that gives you the potential
to stimulate even greater gains in muscle mass, strength and power
in less time. How does CREATINE SELECT™ accomplish this?
Still the most studied, bioavailable and proven
form of creatine in the world.
To combat the double
threat of H+ and Pi, CREATINE SELECT™ begins by sending the
most studied, bioavailable (near 100%) and proven form of creatine
in the world, CrH2O, into your muscles. Despite marketing claims
to the contrary, CrH2O is still the most effective form of creatine
studied to date. Spillane et al. (2009) relate:
"Numerous creatine
formulations have been developed recently… A comparison of
creatine monohydrate [CrH2O], creatine with dextrose, and effervescent
creatine showed added benefit when dextrose is combined with creatine,
but no additional benefits of effervescent creatine compared to
[CrH2O]. Another study combined creatine with magnesium and showed
no additional performance benefits compared to [CrH2O]. Additionally,
creatine solubilized in liquid was ineffective at increasing creatine
retention compared to [CrH2O]."
In their study, Spillane
et al. compared CrH2O with creatine ethyl ester (CrEE) in resistance
exercising subjects. CrH2O not only raised muscle total creatine
levels faster than CrEE (in 6 days vs. 27 days), but it also resulted
in lower levels of creatinine, a waste product of creatine. In
fact, unlike CrH2O, CrEE raised creatinine levels above the normal
range. Furthermore, subjects taking CrEE gained fat mass (body
fat), while those taking CrH2O lost more than 3 lb of it. And
despite the claims of marketers of supplements containing CrEE,
Spellane et al. found that this form of creatine caused extracellular
water retention (edema), a condition which can reduce muscle definition
and is associated with muscle catabolism.
Reinforced with Beta-Alanine, Electrolyte-Bound
Phosphates and Cinnamon Bark Extract
As effective as CrH2O
is, taking it by itself can be a one-dimensional experience. Beverly's
research and development scientists therefore reinforced new CREATINE
SELECT™ with beta-alanine, electrolyte-bound phosphates and
cinnamon bark extract. Each ingredient has been hand-picked to
protect you from premature muscle fatigue according to its own
unique mechanism of action, and balanced with respect to the others
for maximum pharmacokinetic and pharmacodynamic impact. CREATINE
SELECT™ thereby enables you to extend the duration of your
sets and improve your gains more than if you took any one of these
ingredients alone.
Several years ago Beverly
uncovered studies proving that the combination of CrH2O and electrolyte-bound
phosphates produced superior results compared to taking CrH2O
alone. For instance, a 2005 study by Eckerson et al. reported
that this combination significantly increased anaerobic working
capacity by almost 24% in only 2 days and nearly 50% in 6 days.
When subjects received CrH2O by itself, in contrast, it failed
to significantly increase anaerobic working capacity.
Beta-Alanine is another
ingredient that has proven itself in scientific studies. When
added to the diet, it can increase muscle levels of carnosine
as much as 80% in 10 weeks (Hill et al. 2007). Carnosine lowers
levels of H+, possibly explaining why other studies have reported
that beta-alanine supplementation can produce increases in bench
press power (by 15%) and the number of reps performed in the squat
exercise (22%) as compared to supplementation with a placebo.
Further strengthening
CREATINE SELECT™ is the addition of cinnamon bark extract.
Beverly's R&D scientists added this ingredient to support
insulin sensitivity and creatine uptake. Studies involving healthy
humans (Solomon and Blannin, 2009) show that cinnamon feeding
can increase insulin sensitivity immediately and last for 12 hours.
Beta-Alanine, electrolyte-bound phosphates, cinnamon bark extract
--with this carefully balanced combination, it's no surprise that
users of new CREATINE SELECT™ describe it as the best workout
partner ever.
Six isn't where this story ends.
By partnering with
new and stronger CREATINE SELECT™, no longer do your sets
have to end at six. Beverly's breakthrough formula supports the
fastest possible improvements in the appearance and performance
of your physique by tackling the principal causes of premature
muscle fatigue during resistance exercise.
These
causes most commonly result in a decline in muscle force, shortening
velocity and power, all of which CREATINE SELECT™ helps prevent
using the most studied, bioavailable (near 100%) and proven form
of creatine in the world, CrH2O, reinforced by ?-alanine, electrolyte-bound
phosphates and cinnamon bark extract. Each ingredient has been
tested and reviewed for purity and carefully balanced for maximum
pharmacokinetic and pharmacodynamic impact. Finally, Beverly's
R&D scientists left no stone unturned in making CREATINE SELECT™
the very best tasting formula of its kind!
Forced reps and drop
sets are great; however, they are no replacement for lifting the
same load for more reps, or a heavier one. With new CREATINE SELECT™
you get a workout partner that prevents premature muscle fatigue
so effectively you'll be able to accomplish both, and for only
a dollar a serving.
CREATINE SELECT™ contains ingredients that
published scientific studies suggest may safely promote (where
UP = "increase" and DOWN = "decrease")*:
UP - plasma creatine (>15-fold)
UP - muscle creatine and phosphocreatine (up to 40%)
UP - muscle carnosine (up to 40%)
UP - plasma and erythrocyte phosphate
UP - mitochondrial function
UP - ATP resynthesis
UP - delay of muscle failure
DOWN - sensations of fatigue
UP - muscle force
UP - muscle shortening velocity
UP - muscle mean and peak power
UP - anaerobic work capacity (up to 3x more than with creatine
alone)
UP - total lifting
volume (>25%)
UP - lifting repetitions (>20%)
UP - lean body mass (1-2 lb)
UP - muscle cross-sectional area (size) (within 6 days)
DOWN - fat mass (body fat) (within 6 days)
UP - maximal oxygen uptake
UP - muscle hydration
UP - insulin sensitivity (immediately)
UP - glucose disposal
UP - blood glucose control
UP - antioxidant protection
UP - positive mood (anti-depressive action)

New
and Stronger CREATINE SELECT™ Frequently Asked Questions
(FAQ)
1. What is new CREATINE SELECT™?
CREATINE SELECT™
supports the fastest possible improvements in the appearance and
performance of your physique by tackling the principal causes
of premature muscle fatigue during high-intensity exercise. The
three most common signs of fatigue are a decline in muscle force,
shortening velocity and power, all of which CREATINE SELECT™
helps delay using the most studied, bioavailable (near 100%) and
proven form of creatine in the world bolstered by beta-alanine,
electrolyte-bound phosphates and cinnamon bark extract. Each ingredient
has been tested and reviewed for purity and carefully balanced
for maximum pharmacokinetic and pharmacodynamic impact. Finally,
Beverly's R&D scientists left no stone unturned in making
CREATINE SELECT™ the very best tasting formula of its kind.
2. Can anyone use new CREATINE SELECT™?
CREATINE SELECT™
is intended for use as a dietary supplement by men and women 18
years of age and older who perform high-intensity exercise in
an effort improve their physique and performance. Premature muscle
fatigue is a constant threat to anyone who works out with weights
(resistance exercise) or performs any other kind of high-intensity
exercise such as mixed martial arts, sprinting, interval training,
etc.
3. What makes new CREATINE SELECT™ different
from other creatine-containing supplements?
a. CrH2O: As
with the original formula, new CREATINE SELECT™ contains
creatine monohydrate (CrH2O). This is still the world's most bioavailable
(near 100%), proven and cost-effective form of creatine studied
to date. CrH2O continues to outperform other forms of creatine
in study after study, including CrEE, polyethylene glycosylated
creatine, creatine-magnesium chelate and effervescent creatine,
among others.
Many companies have
replaced CrH2O with these other forms of creatine in their supplement
formulas and made marketing claims for their superiority, despite
scientific evidence to the contrary. This ends up costing consumers
their time and money. For instance, a number of supplements contain
creatine ethyl ester (CrEE). Studies by Spillane et al. (2009)
show that CrH2O not only raises muscle total creatine levels faster
than CrEE (in 6 days vs. 27 days), but it also results in lower
levels of creatinine, a waste product of creatine. Whereas CrEE
raises creatinine levels above the normal range, CrH2O does not.
Subjects taking CrEE and performing resistance exercise actually
gained fat mass (body fat), while those taking CrH2O lost more
than 3 lb of fat. Also, CrEE promoted extracellular water retention
(edema) which can reduce muscle definition and is associated with
muscle catabolism.
b. Protection from
Premature Muscle Fatigue: Premature muscle fatigue is a constant
threat to anyone who performs high-intensity exercise. During
resistance exercise, for instance, it causes your sets to be terminated
early; that is, you reach muscular "failure" sooner.
This makes getting a good pump more difficult and otherwise impairs
your ability to burn calories and stimulate gains in muscle mass,
strength, power and other beneficial adaptations. New CREATINE
SELECT™ has been designed to serve as your exclusive defense
against premature muscle fatigue by tackling its two principle
causes, H+ and Pi. These substances are natural by-products of
energy metabolism. The levels of H+ and Pi increase rapidly during
high-intensity exercise and are associated with reductions in
muscle force, shortening velocity and power. CrH2O, ?-alanine
and electrolyte-bound phosphates combat H+ and Pi according to
their own unique mechanisms of action. Thus, by combining them
into one formula, you can experience greater results than if you
took any one ingredient alone.
c. Extended Action
("Three Winds"): Perhaps the simplest way to think
of new CREATINE SELECT™ is that it provides "three winds"
of performance enhancement during your workouts: Besides its rapid
effects on total and lean body mass, CrH2O provides the first
performance-enhancing "wind", possibly lasting 3-5 sets,
depending on the length of your rest intervals and other factors.
The addition of electrolyte-bound phosphates provides a "second
wind" that kicks in as the first one begins to fade. The
result may be to double your lifting capacity, if not produce
even greater results, over the range of, say, 6-12 sets. Users
of new CREATINE SELECT™ can now enjoy a "third wind"
with the addition of ?-alanine. With each of these "winds"
carrying your muscles through your workouts in overlapping succession,
you can experience a tempestuous boost in performance that more
than satisfies even the most advanced athlete throughout his or
her entire workout and results in superior gains in muscle mass,
strength, power and definition in less time.
d. Immediate Insulin
Sensitivity: By affecting creatine uptake, insulin sensitivity
determines how well you respond to CrH2O, among other things.
To ensure that you respond to each serving of CREATINE SELECT™
as favorably as possible, Beverly's R&D scientists added cinnamon
bark extract. Cinnamon feeding has been shown to increase insulin
sensitivity immediately in healthy humans (not just those with
diabetes) and the effects persist for 12 hours.
e. "Tastes
like Tang": Taste and color are as important as functionality.
Indeed, it's great that CREATINE SELECT™ works so well, but
if you are going to use it every day, you want it to taste and
look great, too. Not satisfied with the taste of the original
formula, Beverly's R&D scientists experimented with different
proportions of flavoring agents until they arrived at a recipe
that is so delicious, one recent user claimed that new CREATINE
SELECT™ "tastes like Tang!"
Color is especially
important for a powdered drink mix like CREATINE SELECT™.
The most powerful formulas aren't necessarily the most appetizing
in appearance when mixed up with water. To give the new CREATINE
SELECT™ formula a natural orange tone that would appeal to
its users, we varied the amount of annatto oil. Annatto oil comes
from the seeds of a small shrub known as Bixa orellana. Annatto
oil is rich in carotenoids and, besides displaying antioxidant
properties, it has been shown to increase the binding of insulin
to the insulin receptor in animal studies.
f. Tested and Reviewed
for Safety & Purity: Like the rest of Beverly's formulas,
all of the ingredients in new CREATINE SELECT™ have been
tested and reviewed for safety and purity. Whenever possible,
we use pharmaceutical-grade ingredients. We also strive to use
the most cost-effective ones (like CrH2O) so that you don't have
to pay unfair prices to improve your physique and performance
in the fastest possible time.
g. Only $1 per serving:
Because Beverly chose to use the most cost-effective (and
bioavailable and scientifically proven) form of creatine in the
world, we were able to make new CREATINE SELECT™ cost only
a dollar a serving.
h. Pharmacokinetically
& Pharmacodynamically Balanced: "Pharmacokinetics"
refers to what your body does to an ingested substance (e.g. creatine,
aspirin, beta-alanine, glucose), including how it is absorbed
and excreted. "Pharmacodynamics" refers to what the
substance does to your body, including any beneficial outcomes.
Because each ingredient in CREATINE SELECT™ has a different
chemical structure, it also has its own unique pharmacokinetic
and pharmacokinetic properties. As indicated above, for instance,
CrH2O, ?-alanine and electrolyte-bound phosphates combat H+ and
Pi according to their own unique mechanisms of action. Thus, by
combining them into one formula, you can enjoy a greater range
of potential benefits. Each ingredient in CREATINE SELECT™
has been balanced with the others for maximum pharmacokinetic
and pharmacodynamic impact.
i. Clinically Proven
to Work: The three main ingredients in new CREATINE SELECT™
-- CrH2O, ?-alanine and electrolyte-bound phosphates-have been
proven to provide a variety of benefits in clinical studies involving
humans. Importantly, Beverly's R&D scientists have put sufficient
quantities of each ingredient in CREATINE SELECT™ to enable
you to achieve these benefits safely and effectively.
j. Real Energy,
No "Crash": New CREATINE SELECT™ produces real
and lasting increases in muscle energy levels, unlike stimulants,
which produce an illusion of greater energy that quickly fades,
often followed by depression and lethargy. The CrH2O in CREATINE
SELECT™ can raise your muscle phosphocreatine levels by up
to 40%. Phosphocreatine plays a critical role in the regeneration
of ATP during high-intensity exercise. ATP is as real as energy
gets. It is the ultimate "energy currency" for your
muscle cells and every other cell type in your body. Without ATP,
muscle contraction would stop, as would life itself. Furthermore,
because CREATINE SELECT™ is entirely free of caffeine and
other stimulants, it is easily tolerated no matter what time of
day it is taken.
4. When can I expect to see results while using
new CREATINE SELECT™?
Ingredients in new
CREATINE SELECT™ have been found to produce effects according
to the timetables indicated below:
a. Absorption: Studies
suggest that the maximum absorption of 10 grams of CrH2O occurs
within 2 hours. One serving of CREATINE SELECT™ contains
5 grams of CrH2O and therefore may be expected to achieve maximum
absorption even sooner.
b. Increases in muscle strength and power: Within 5-30 days of
supplementation.
c. Increases in lean (e.g. muscle) mass: Within 6 days of supplementation.
d. Reductions in fat mass (body fat): Within 6 days of supplementation.
e. Myonuclei per muscle fiber: Within 4 seeks of supplementation.
f. Mean muscle fiber area: Within 4 weeks of supplementation.
g. Insulin sensitivity: Increases in insulin sensitivity may occur
immediately following supplementation and last up to 12 hours
if not longer.
h. Mental function: Studies have found that increases in intelligence
tests scores and working memory are possible during 6 weeks of
supplementation.
5. Can I stack new CREATINE SELECT™ with
UP-LIFT™?
Yes. One of the reasons
that UP-LIFT™ is creatine-free is so that it can be stacked
with other supplements containing creatine, such as CREATINE SELECT™.
Users of both products may experience a synergy between their
respective ingredients that results in even greater workout performance
and gains in muscle mass, strength, power and reductions in fat
mass.
6. If I don't perform resistance exercise, can
I still benefit from using new CREATINE SELECT™?
CREATINE SELECT™
is capable of providing you with benefits (e.g. increases in total
body mass, mental function) whether or not you currently exercise.
However, you can expect far greater benefits when using it as
a supplement to a calorically-appropriate diet and a regular program
of exercise. Because resistance exercise is more efficient at
stimulating muscle protein synthesis, you can expect greater gains
in muscle mass, strength, shape, tone and definition when using
CREATINE SELECT™ while performing this type of exercise.
7. What are the benefits of supplementing my
diet with new CREATINE SELECT™ over the short and long term?
New CREATINE SELECT™
contains ingredients that published scientific studies suggest
may safely promote (where UP = "increase" and DOWN =
"decrease")*:
UP - plasma creatine
(>15-fold)
UP - muscle creatine and phosphocreatine (up to 40%)
UP - muscle carnosine (up to 40%)
UP - plasma and erythrocyte phosphate
UP - mitochondrial function
UP - ATP resynthesis
UP - delay of muscle failure
DOWN - sensations of fatigue
UP - muscle force
UP - muscle shortening velocity
UP - muscle mean and peak power
UP - anaerobic work capacity (up to 3x more than with creatine
alone)
UP - total lifting
volume (>25%)
UP - lifting repetitions (>20%)
UP - lean body mass (1-2 lb)
UP - muscle cross-sectional area (size) (within 6 days)
DOWN - fat mass (body fat) (within 6 days)
UP - maximal oxygen uptake
UP - muscle hydration
UP - insulin sensitivity (immediately)
UP - glucose disposal
UP - blood glucose control
UP - antioxidant protection
UP - positive mood (anti-depressive action)
8.
Is new CREATINE SELECT™ safe for people with medical conditions?
In scientific studies,
CrH2O has been given to healthy subjects as well as subjects suffering
from a variety of medical conditions. Nevertheless, it is advised
that you discuss CREATINE SELECT™ with your medical doctor
before using if you have a medical condition, or if you are currently
unaware of your health status.
9. Is new CREATINE SELECT™ safe if you
are trying to become pregnant, or are currently pregnant or nursing?
Discuss CREATINE SELECT™
with your medical doctor before using if you are trying to become
pregnant, or are currently pregnant or nursing.
10. Can CREATINE SELECT™ be used during
preparation for a bodybuilding competition? What about a fitness
or figure competition?
Yes. Bodybuilders,
fitness and figure competitors need to hold onto as much of their
muscle mass as possible while burning fat. This is one of the
potential benefits of using CREATINE SELECT™. Many Beverly
customers stack CREATINE SELECT™ with 7-KETO MUSCLEAN™
and LEAN OUT™ in order to increase calorie burning, enhance
fat loss and prevent the retention of water under the skin.

service team for help in developing your ideal bodybuilding or
shaping stack. Contact information is provided below.
11. I'm not a "spring chicken" anymore.
I just turned 52. What kind of benefits can new CREATINE SELECT™
provide me with?
The ability to gain
muscle mass, strength and endurance, reduce fat mass, and improve
cognitive function are things of interest to the young and old.
Particularly as we age, we find it difficult to preserve muscle
mass and functionality. The same can be said for our mental state.
Ingredients found in CREATINE SELECT™ have been found to
reverse these signs of aging. For a full list of potential benefits,
see question 7, above.
12. Where is new CREATINE SELECT™ made?
CREATINE SELECT™
was formulated and tested by Beverly's R&D scientists at the
Beverly International Nutrition head office in Cold Spring, Kentucky.
Each ingredient has been selected based on studies published in
publicly-accessible databases such as those made available by
the National Center for Biotechnology Information (NCBI).
13. Where can I obtain product support?
