After taking the initial 21 day packets, I felt so much better about my work-outs. I started to "feel" the way I was working out! this is a product I will continue to use!

I alternate the Stak with the Test. I take two cycles of the Test then one cycle of Stak. I feel the added endurance in my workouts as opposed to when I wasn't taking either product. I have been training all of my adult life and at age 52 the testosterone level decrease significantly. This product has supplemented my testosterone level and allows me to keep lifting reasonably heavy. I train 6 days a week and I enjoy all the Universal products.

I've only been on bodybuilding.com for about a year, but this so far is the first product I am taking the time to write a review simply because I think it deserves a higher rating than what it is currently at. I followed the directions and didn't miss a day, and I can honestly say in one months time I had made the biggest and most noticeable gains than in any other period of time in which I have tried to put on size. Granted, I went all out and was very religious with everything (diet, lifting, other supplements) so I cannot say it was entirely because of this product, but I do believe this played a large part. I highly recommended it.

I've good this about this product from my buddies so I gave it a try. It worked great my energy level was up, sex drive, strength and overall growth. I put on 5lbs of lean muscle while loosing 1.5% body fat in my three week cycle. By far one of my favorite products. I have used animal pak for a long time and always have loved it. I've stopped using pre workouts wen I was on it to see the overall effect. I was only using creatine mono, animal pak, animal flex(which I love), animal stak, and whey protein. It did wat it said and more. I have more definition size and strength in three week cycle

Not a huge fan of taking down pills but definitely think it's a requirement for certain supplements effective dosing. Noticed a much higher frequency of gains in terms of strength and even size some. Never benched over 75 on the DB's and never comfortably done 205 BB. Easily jumped to reps of 85lb DB's and can easily 3 rep 205 since the span of use. Definitely going to be a repeat customer of Universal.

I used this product again and I will say it was amazing!! My rep bench is 275 lbs my squat rep is 255 at 10 times. I don't deadlift anymore because of my back. This is an extreme builder and you will be able to put mass quickly anywhere you want.

I tried my first test-stimulant, AH-D which worked pretty well. Definitely noticed the vascular increase. After taking Animal Stak it was clear it was the better choice. Not only did I increase even more after that from the vascularity aspect but I noticed I was able to push through harder during intense workouts and felt like I could do more afterwards. My body mass also increased and it fits perfect with a CrossFit WoD or HIIT routine (hard exercise = faster results).

I have always been impressed by the Animal products line. I have used the original Animal Paks since the 80s and I am always willing to try a new addition to the line. Animal Stak is a terrific natural testosterone and growth hormone booster. Since adding Animal Stak to my regimen, I am stronger in the gym and recover quicker between sets. Well done, Animal!

9/10

Building block and pilar for mass building, effective testbooster ideal for serious lifters or anyone who wants the benefits of a quality testbooster. The go to product for pros and those who don' t know and don' t want to worry about the quality of the ingredients blends and compositions offered by some other brands. Recommended for serious weightlifters in their late 20's early 30's.
