got potential to be greater than you are. That's why you're in this
game. You just gotta tap into it. Animal Stak was designed to help you
get the most out of the anabolic hormones you already have pumping
throughout your body.
PR on squats, 20lb PR on bench, 30lb PR on deadlifts, with a 515 sumo
out of nowhere in just three weeks. 13lb increase in body weight in
just 21 days. Those are HUGE, almost ridiculous changes in such a short
time. Almost like one of those infomercials you get pissed off at when
they come up on TV. but real." - Firefist via Animal FORVM
original, prohormone-free Animal Stak was launched over nine years ago,
and though the formula was cutting-edge at the time, non-hormonal,
anabolic supplements utilizing natural hormone boosters were still in
their infancy. Almost ten years later, many new compounds have come
onto the scene, pushing the envelope and raising the bar as weve
always strived to do at Animal Enter the all-new & improved Animal
Stak. Building on the legacy built by the original and popular Animal
Stak formula, this new and improved version has taken the most potent
components of its predecessor, combined it with newer nutrients and
cranked it up to the next level. Animal Stak has long been built on
being a complete anabolic hormone stack. Its not just a testosterone
booster. Its also a GH booster and an anti-aromatase. Stak also
contains specialized hormone amplifiers and restorative nutrients to
optimize ones internal anabolic environment. It is extreme and
all-encompassing, just like every pack in the Animal line.
With Animal Stak you get a mega-potent dose of 1500mg of
pro-testosterone boosters. The Pro Testosterone Complex found in Animal
Stak includes a variety of ingredients that help to elevate both of
your testosterone levels: free and total. Testosterone is the primary
hormone that interacts with skeletal muscle tissue and as many know,
testosterone's role is paramount in muscular development. When it comes
to optimizing testosterone levels, there's a couple of things to take
into consideration. You want to make sure your testosterone levels
aren't low - nutritional deficiencies can cause low serum testosterone
levels. You also want to make sure that your ratios of free
testosterone to total testosterone are advantageous. Free
testosterone is the form of testosterone that exerts the anabolic
effects strength athletes are after; it's the stuff that gives you
results. By addressing all these issues, you could tap into your body's
true potential. Stak gives you one and a half grams daily of natural
test enhancement in every pack. Thats serious.
The Pro Testosterone Complex in Animal Stak addresses these aspects of
hormone management mentioned above. Primary among these are tribulus
terretris extract and longjack extract. Tribulus terretris extract is a
potent source of protodioscin and steroidal saponins; important
compounds that support natural testosterone release. The long jack
extract complex contains patented LJ100 which supplies EuryPeptides,
glycosaponins and polysaccharides, to increase free testosterone
levels. Human clinical trials suggest that this compound almost doubles
testosterone and increases free testosterone while decreasing Sex
Hormone Binding Globulin (SHBG) (the compound that binds to
testosterone to keep it in the unusable state), as well as increasing
All in all, you can think of the longjack extract complex as the
doorway that helps allow increased free testosterone to flow through
your blood. In addition, the Pro Testosterone Complex is rounded out by
fenugreek seed, stinging nettle root and maca extract. Fenugreek
contains high amounts of furostanolic saponins, which are natural plant
chemicals that can boost testosterone levels. Finally, this complex
contains an exotic herb that is native to Peru, maca extract. Maca is a
purported aphrodisiac and libido booster that contains specialized
plant sterols. Researchers that worked with maca speculated that it
naturally increases free testosterone levels. Working synergistically
with these other pro-free test substrates, that speculation rang loud
enough to make the cut in the reloaded Stak.
Next up in Animal Stak is the GH Support Complex This complex consists
of specialized natural growth hormone (GH) boosters and support agents.
Growth hormone is a protein-based polypeptide hormone made up 191 amino
acids that is synthesized and secreted by cells in the anterior
pituitary called somatotropes. GH plays a vital role in several complex
physiological processes, including growth and metabolism. How does GH
benefit athletes? GH is a highly coveted anabolic hormone that
stimulates growth in most body tissues, including skeletal muscle
tissue, primarily due to increasing total cell numbers.
Protein synthesis and the transport of amino acids are increased when
GH is naturally increased. These effects are mediated by insulin-like
growth factor (IGF-1), another highly anabolic hormone produced in the
liver and other tissues in response to GH increase. Growth hormone also
helps to increase the use of fat as a primary fuel source, which in
turn, helps build a more lean physique. GH has also been shown in a
number of studies to increase mood, memory, immune health, increase
cardiac function, better sleep and increase oxygen uptake. Being able
to naturally tap into the effects of GH can be a major key to
maximizing recovery and muscle repair during the nighttime recovery
Kicking off the GH Support Complex is a specialized Arginine Complex
comprised of two key forms of arginine; arginine HCl and patented
Arginine HCl is a well studied and highly touted amino that can
increase the release of GH. Arginine also has potent modulating effects
on the immune system, improving immunologic responses, accelerating
recovery and reducing the chance for infection. So not only is this
ingredient helping to boost natural GH levels, which has its own set of
benefits, the secondary anti-catabolic benefits are very helpful to
bodybuilders and strength athletes as well.
ArginoCarn® is a research-backed, patented compound made up of acetyl-L-carnitine arginate dichloride. Research shows that ArginoCarn®
increases growth & repair of neurons, supports brain-to-muscle
connection, supports cognitive function and memory and can even enhance
fat burning during calorie restriction via increased mitochondrial use
of fatty acids. GH is considered to be a wonder compound due to its
myriad benefits in terms of wellness, recovery and overall body
composition. To optimize a strength athletes output of growth without
adding dangerous exogenous chemicals is the ideal scenario, hence why
this complex plays such a prominent role in the retooled Stak formula.
Up next in the Growth Hormone Support complex are two, unique patented
compounds- SuperSerum and Sustamine. SuperSerum is rich in naturally
occurring, bio-valuable proteins, growth factors and peptides, while
Sustamine is a special dipeptide with benefits that include the
ability to promote protein synthesis and stimulate immune action as
well as L-alanines ability to supply energy and promote healthy
hydration. Truly next level muscle and performance compounds and Stak
is loaded with efficacious dosages of each.
Rounding out the Growth Hormone Support blend is the phospholipid,
alpha glycerylphosphorylcholine (alpha-GPC) and mucuna pruriens. Mucuna
pruriens is added for its ability to elevate the production of l-dopa,
an amino acid that converts into dopamine. Dopamine is an essential
component of our body and it's required for proper functioning of the
brain. The blood carries dopamine into the brain, where it naturally
increases HGH production from the pituitary gland, important for
recovery and well being..
Another important aspect of Animal Stak is the Anti-Aromatase Complex.
In order to capitalize on the blast of utilizable testosterone provided
by these pro-androgen ingredients, Stak comes fully equipped with a
combination of potent natural anti-estrogens. First among these is the
ultra antioxidant resveratrol. Resveratrol acts like a shield. It binds
to the estrogen receptor and works to block circulating estrogen
hormones from ever hitting the target receptor, thus inhibiting
unwanted estrogens from reaching the hormone receptor. The complex is
then further fortified by hearty dosages of other proven
anti-estrogens; calcium D-glucarate and diinodolymenthane (DIM).
Calcium D-glucarate is a potent antioxidant that helps to inhibit or
stop the beta-glucuronidase enzyme (and a high amount of this enzyme is
bad) that can interfere with the glucuronidation process. When a used
toxin or hormone, such as estrogen remains bound to its water-soluble
bond it will be eliminated from the body rather than being
re-circulated in the blood stream. This helps limit the amount of free
estrogen being reabsorbed and preserves the amount of glucuronic acid
available for detoxifying other problem toxins.
Rounding out the complex is Diindoylymethane (DIM), which a component
of Indole-3-carbinol found in cruciferous vegetables such as broccoli,
kale and cauliflower. DIM blocks the estrogen receptors activity, thus
reducing excess testosterone to estrogen conversion and allowing more
of the desired testosterone to be available for the receptors. In
summary, these constituents work to block circulating estrogen from
reaching receptors as well as negating the inevitable estrogen boost
brought about by excessive testosterone production, thus directly and
indirectly promoting a higher ratio of circulating serum testosterone.
This factor is as critical to the chemical warfare aspect of
bodybuilding as any. It is not enough to simply maximize test output
you have to equally minimize the subsequent estrogenic response.
Weve also included a new Hormone Amplifying Blend that provides key
patented herbs and aminos such as AgmaPure (agmatine sulfate),
GlycoCarn® (glycine propionyl L-carnitine HCl), AstaPure® (astaxanthin) and Bioperine®
with l-carnitine and quercetin mixed in. Together these herbs and
aminos have been shown to help further enhance the natural hormone
boosters in Stak by helping to create the ideal anabolic environment
for them to succeed in. AgmaPure Agmatine Sulfate is thought to
improve nutrient partitioning thus leading to more glycogen storage and
increased water retention within the muscle. It also increases the
level of nitric oxide (NO), which can increase the "PUMP" that athletes
look for when weight training. GlycoCarn® is a powerful, research-backed, patented carnitine form that is made up of glycine propionyl L-carnitine HCl. GlycoCarn®
helps increase nitric oxide (NO) synthesis which causes vasodilation
and allows for greater blood flow and delivery of oxygen to working
muscles. In addition, L-Carnitine has been shown to increase hormonal
responses to resistance exercise and recovery and resulted in a greater
number of intact receptors for hormonal interactions.
(astaxanthin), is a natural super antioxidant carotenoid made by plants
and algae. It has been shown to help increase natural testosterone
production and as an antioxidant, astaxanthin benefits cardiovascular
health, immune system health, eye health and even supports healthy
skin, bones and joints. Quercein is an antioxidant flavonoid found in
certain fruits and vegetable that assists in the bioavailability and
absorption of the other nutrients in the complexes. This is where
Animal attempts to further breakaway from the pack, by creating the
best possible scenario for the anabolic processes intended by the Stak
formulation to work their muscle building "mojo".
Rounding out the new Animal Stak formula is a newly designed
Restorative Support Complex. This complex is jam-packed with
restorative nutrients to optimize ones internal anabolic environment.
The herbs and nutrients within this complex provide important support
for healthy adrenal, liver, cortisol functionall-important but
often-overlooked aspects for not only promoting proper recovery and
repair but also in maximizing natural hormone levels. Healthy organs
and glands keep the system running properly when hitting heavy weights.
The Restorative Support Complex contains a blend of milk thistle,
astragalus, ashwagandha extract, Na-R-Alpha Lipoic Acid (Na-R-ALA) and
Coenzyme Q10. Together they help assist the body from a variety of
restorative angles, allowing better training capacity, improving
endurance, minimizing the catabolic stress response, supporting a
healthy libido and boosting overall immune system function. This is the
ultimate purpose of Animal Stak, thus the reason we go the extra mile
to make sure this new formula is complete, comprehensive and loaded to
