The 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 we've 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. It's not just a testosterone booster. It's also a GH booster and an anti-aromatase.* Stak also contains specialized hormone support 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 promote 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. That's 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 support 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 promoting IGF1 levels.*

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 may help support sexual health and 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.

 

Kicking off the GH Support Complex is a specialized Arginine Complex comprised of two key forms of arginine; arginine HCl and patented ArginoCarn®. Arginine HCl is a well studied and highly touted amino that can support the release of GH.* Arginine also has potent modulating effects on the immune system, supporting immunologic responses and overall health.* 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 suggests that ArginoCarn® supports 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.* To optimize a strength athlete's 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-alanine’s 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 ingredients that help support a healthy estrogen balance.* 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 helping prevent unwanted estrogens from reaching the hormone receptor.* The complex is then further fortified by hearty dosages of other suggested 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.

We've 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 suggested 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 is suggested to increase hormonal responses to resistance exercise and recovery and resulted in a greater number of intact receptors for hormonal interactions.*

AstaPure® (astaxanthin), is a natural super antioxidant carotenoid made by plants and algae. It has been suggested to help increase natural testosterone production and as an antioxidant, astaxanthin support 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 function—all-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, supporting endurance, minimizing the catabolic stress response, supporting sexual health 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 the hilt.
