Universal Nutrition Animal Stak - 21 paks

Animal Stak required for:

  • Maximum muscle gains
  • Igniting anabolic drive
  • Optimizing Test & GH levels
  • Competition & off-season training

Since 1998, Animal Stak has been the #1 selling anabolic pak. Why? Because it works. You're a grizzled veteran of the iron game who knows a little something about bodybuilding. It's not about trash talking. It's about getting no-holds-barred results. Animal Stak gives you the ultimate anabolic edge. It lets you run with the big dogs.

To understand why Animal Stak works, it's necessary to know a little bit about anabolic steroids. Many bodybuilders take anabolic drugs to increase anabolism (e.g., increase amino acid uptake, stimulate protein synthesis, and reduce protein degradation). When all of these cylinders are clicking, you can pack on muscle like there's no tomorrow. Talk to competitive bodybuilders. They'll tell you the most anabolic hormones around are testosterone, growth hormone (GH & IGF-1), and insulin. Control these hormones and you master your own muscular destiny.

That's the good news. The bad news? Let those same hormones run amok and you've got some serious side effects on your hands: prostate enlargement, acne, gynecomastia ("bitch tits"), premature balding, testicular shrinkage, just to name a few. This is especially true when exogenous testosterone (anabolic steroids) derivatives are introduced into the body. With legal prohormone supplements, similar side effects can also occur, albeit on a much milder scale. Why? Because with increased testosterone conversion comes the increased potential for the testosterone to convert to other hormones such as estrogen and dihydrotestosterone (DHT).

What makes Animal Stak unique in the bodybuilding supplement world is its ability to both enhance the production of all these desirable anabolic hormones while simultaneously reducing the potential for DHT and estrogen conversion. Only Animal Stak accomplishes this by including over 25 powerful, active ingredients in every comprehensive pak. In each pak, a unique set of tablets and capsules deliver the right ingredients in the right combinations at the right time to promote your body's powerful anabolic drive. Animal Stak also provides the added benefit of helping to protect your liver, the site of prohormone conversion to testosterone.

Animal Stak is complete. It's got everything you need. For starters, each individual pak contains 250mg of the most comprehensive prohormone complex available.

If these prohormones weren't enough, we've also added nearly 5 full grams of growth hormone-releasing secretagogues and substrates. In other words, Animal Stak can also boost growth hormone (GH) release; increase protein synthesis further; exert anti-catabolic effects; and promote new growth. There's nothing else in the world that combines the powerful 1-2 punch of testosterone and growth hormone in one formula. These GH secretagogues have been shown in studies to boost GH levels by up to eight times over baseline values 30-90 minutes after oral administration. This GH complex also initiates GH secretion through the opioid peptidergic system in the hypothalamus for additional benefits.

We've also included a special grade of colostrum that is naturally rich in IGF-1. IGF-1 or insulin-like growth factor 1 is a single chain 70 amino acid polypeptide that scientists believe is the active anabolic effector of hGH. Colostrum also contains other anabolic protein fractions including interleukin 1 (IL-1), FGF and EGF. Unlike steroids, IGF-1 directs new muscle protein synthesis rather than helping muscle cells simply retain amino acids and enhancing glycogen synthesis. IGF-1's function is intimately linked to GH: GH works largely by its effects on IGF-1. Inside muscle cells, IGF-1 mediates the actions that growth hormone directs. Unlike GH however, IGF-1 can promote muscle growth by itself.

Not stopping there, we've also added luteinizing hormone (LH) boosters. The LH component to Animal Stak can increase LH release in the pituitary by up to 72%. In Eastern Europe, nutrients which promote LH release (and found in Animal Stak) have been used by strength athletes to great success for decades. LH is a pituitary hormone which signals the body to make more testosterone.

Animal Stak is a professional-strength growth and performance formula. It's the strongest formula you can use without a prescription. Because of its powerful nature, we've added equally powerful ingredients to alleviate any potential side effects, including dihydrotestosterone (DHT) blockers, estrogen blockers (anti-aromatase inhibitors), liver support nutrients (the site of prohormone conversion is the liver), and key vitamins and minerals.
