Animal Stak


Availability: In stock

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.

The hormonal edge is what separates the lifting elite from the rest of the gym culture. Testosterone and growth hormone (GH) production, and aromatase regulation, are crucial in an iron athlete’s ability to grow new muscle, and to add size and strength. Hence, the popularity of steroids and performance-enhancing drugs in elite athletics. Instead of turning to using illicit compounds to augment their internal anabolic environment, many serious lifters have sought healthier, natural methods for raising their game.

It is with this goal in mind that Animal developed Stak, more than a decade ago. A legacy built in the trenches for delivering an anabolic and androgenic advantage through safer, legal means, the Animal Stak formula is constantly being updated. Providing the most cutting-edge, no-nonsense anabolic hormone boosting nutrients to bodybuilders and powerlifters who will settle for nothing less. The goal is to get bigger and stronger. To enhance performance. But to do it by optimizing a lifter’s internal hormone synthesis naturally.

Loaded with potent herbs, vitamins, minerals, amino acids and powerful patented compounds, each pre-dosed pack of Animal Stak is designed to naturally enhance the testosterone and growth hormone output of hard-training bodybuilders, all the while minimizing the production of estrogen and cortisol—the gain-killing hormones. Stak even includes substrates designed to restore endocrine health and amplify endogenous hormonal output. Stak seeks to naturally boost the anabolic hormones linked to power and mass, but to do so without shady ingredients and gray-market compounds.

Built on a legacy with roots more than a decade deep, the latest version of Animal Stak borrows the most powerful ingredients of its predecessors, combined with new school nutrients intended to crank it all up to the next level. More than just a testosterone booster, a HGH production catalyst or an anti-aromatase, the sum of Animal Stak is greater than just its individual parts. It is all of these, and then some. Animal Stak is extreme and all-encompassing, just like every other pack in the storied Animal line.

For those who constantly seek an edge, and a means to push past their limits, there is Animal Stak—powerful and complete, all-around, natural anabolic hormone support.

This stuff works

Review by Mason / (Posted on 3/28/2018)
When I first looked at the supp facts for this product, I was iffy. But the girl at the local supplement store said it would work well so I decided to pull the trigger. Three workouts into it, I was stunned. The pump was stupid, I felt great all day, and my strength and endurance went up. I’d highly recommend this, especially for the price!

Frequently Asked Questions

What’s the difference between the new M-Stak and Stak?

We designed both the Stak and M-Stak to be natural anabolics, but each works differently. Stak is a natural hormone booster. It works with your body to help enhance key anabolic hormone levels, including testosterone.
Animal M-Stak, on the other hand, works to promote anabolism by increasing protein synthesis, nutrient portioning, nitrogen retention, all the while reducing muscle catabolism. In short, Animal Stak can help with performance and strength whereas Animal M-Stak can help with gaining lean mass and size. You can combine the two to get the best of both worlds.

Do I need to run a PCT after running Stak?

No, there is no need to do so.  Our products increase your natural hormone production by means of natural ingredients, not by introducing outside hormones to the system.  Therefore, there is no shutdown, rebound, etc. 

Can I "stack" Animal Stak with Animal M-Stak?

Absolutely. In fact, this would be a solid stack, no doubt. Both promote anabolism in their own unique way and neither formulas overlap. M-Stak enhances protein synthesis and "nutrient partitioning" while Stak increases and optimizes the utilization of anabolic hormones.

Can I take a fat burner along with Stak?

Absolutely. Using a fat-burner along with Stak will not interfere with its effects on natural hormone production. Just be sure to leave 3-4 hours in between the time you use the fat burner and the time you take Stak. In such case, take your fat burner pre-workout as you normally would and use your Stak either a couple of hours before or after training. While it may not be completely necessary to divide the dosing, doing so will ensure optimal absorption.


" I just went through my first cycle of Stak and have seen the best results of my life. Now I'm on M-Stak and I haven't lost a step. I feel stronger and I look leaner. Just wanted to say you guys are doing good work there and I plan to keep taking your products."

“I had very good gains, mainly in strength when I used Animal Stak. I went from partial squats with 340 lbs, 5 reps to partial squats with 400 lbs, 10 reps over a 6 week period (I only used it on training days instead of taking it every day for 3 weeks)… I am going to guy Animal Stak again… thank you for making excellent products.”
