Universal Nutrition Animal Stak 21 packs | Natural Test & GH Booster

From Universal Nutrition, one of the most trusted brands in the fitness industry, comes an all-natural anti-catabolic hormone supplement, the Animal Stak. Unlike many other anti-catabolic products on the market, Animal Stak is completely prohormone free and works in conjunction with your body’s natural hormone production. Animal Stak promotes test and GH regulation, while also controlling estrogen aromatization, giving you a sizeable boost in strength and power while making your body conditions ideal for growing new muscle. With many competitor products featuring illicit compounds that claim to accomplish these same results, Animal Stak uses completely all-natural ingredients– there is no need to take a PCT afterwards as there is no shutdown or rebound following a cycle. Animal Stak is way more than just a test booster, it was specifically designed to naturally augment your body’s anti-catabolic hormones that are linked to power and mass. Each serving of Universal’s Animal Stak is brimming with the most powerful and all-natural herbs, vitamins, minerals, and amino acids alongside proven compounds that will naturally increase your test and Growth Hormone (GH) output. What’s more, Animal Stak also combats the aromatization of estrogen and cortisol, hormones that can have an extremely detrimental effect on your fitness goals. With Animal Stak, you will experience strength and power unlike anything you’ve ever felt before, and you can feel satisfied knowing that it was all accomplished naturally. With a cutting-edge formula and all-star ingredients, Animal Stak delivers on the quality and effectiveness that we’ve come to expect from Universal Nutrition – no fillers or shady ingredients, just real results. Order your tub of Universal Nutrition’s Animal Stak today and push past your limits!

Directions and Dosage

Universal Nutrition recommends taking one pack daily for 3 consecutive weeks. On training days, take one pack 30 minutes prior to exercise. On non-training days, take it on an empty stomach, between meals. For best results, cycle this product following a schedule of three weeks on and one week off.


Animal Stak is ideal to stack with Animal M-Stak – while they are both natural anti-catabolic supplements, their functions complement each other. While Animal Stak is a natural hormone booster, Animal M-Stak works to increase protein synthesis. If you want to increase your mass alongside the power and strength boost you’ll get with Animal Stak, definitely add Universal Nutrition’s Animal M-Stak to your arsenal.

Go mode

So this is nearly as effective as a pro hormone. So I personally use it when I cycle off. So side effects that I've notice over 2 cycles. Only complaint is the volume of pills but the results are legit.

I was initially very satisfied with how quickly my supplement order was delivered to me in Afghanistan. However, when I opened my box, I found that a coue of the items I ordered were not there. Those items had been highlighted on the packing list, leading me to believe that they were on backorder and not available at the time the shipment t was made. There was no other notification, either written or by email, as to whether those items were, in fact , on back order or if they were ever expected to come in or be shipped to me. I have e sent 3 email inquiries in this matter and have not gotten a single response. I have had similar experiences with Supplement Warehouse in the past, but for some reason, keep coming back to them. Perhaps this time I have learned my lesson. Still hoping to see those two items some day........
