Within 1 day of taking you start feeling that edge. Workouts that normally would leave me sore for days felt like warm-ups. Great for hard gainers, especially if stacked with M-Stak. A bulking must have!

Animal Stak has been one of my staple supplements for many years. This product is one among the “old-school” supplements that have proven effective for muscular endurance and development over the long term.

Its pretty good for gaining strength I've stacked this with mstak an got good results. Together they work to keep your body anabolic even on a cut. I recommend this product.

I have been a big animal fan for year starting with the pack then the PM. I always had wondered about the stack. Gave me a nice boost if taken pre workout, otherwise I would take it before bed to help with recovery.

Took the can 21 days in a row while eating and lifting heavy did not notice anything different. Better off spending money on meat and veggies.

What can I say about Animal Stak. Honestly Did not meet expectations.. kind of upset I spent this much on these... honestly didnt help me out much if any at all. Could not tell any difference. Pretty upset about the product kind of feel as if i wasted my cash. But i did recieve it very very quickly and efficiently thanks bodybuilding.com you were the best part of this experience.

On my second 21 day stack now. I have noticed gains in strength and cuts. Very pleased with this product. Just an FYI it is 8 pills per pack. So if you don't like taking pills this isn't a product for you.

Good product, always seem to see good gains with the proper nutrition. Will say...a lot of pills if your not into that thing

I did a lot of research before taking this, but I'm pretty happy with the results so far. I'm 2 weeks into the stak (it comes with 3 weeks worth of packets) and when I'm in the gym I feel more energized as well as more pumped. I will say it made me noticeably more irritable and break out a little bit. Theres eight total pills per stak, and going down they leave a bit of a weird taste. I'm gonna finish the stak then give it a break for a bit before going back on. I'd recommend this to someone trying to up his weight training.

Yes, swallowing all those pills can be rough...But it is definitely worth it. I went harder and longer in my workouts while on the stak. Saw increase in muscle size as well as definition. For those of us that have trouble gaining weight and size, this products worked wonders. Will for sure use this product again and again.

I've tested the animal stak by itself, and in conjunction with animal test, results were obvious in muscle definition, volume, and strength. Only thing i hope universal nutrition would do in all the animal series, is to take out the artificial colorants from the pills, or use a natural alternative to identify the stimulant pills in the packs.
