Pretty shocked

Great! I didn't expect much as OTC products usually aren't that great. To my surprise, I started to notice the effects in drive at the gym within the first week. Takes some time to build up, once it hits, loving it!!!

Pretty good

I bought this product to build muscle and have more endurance in and out of the gym. On my first cycle i was a little leary of wether it was going to work or not. But after about 4 weeks i started seeing changes. At the end of my first six weeks i gained 7lbs of solid muscle. Also i felt as if i had quite a bit more endurance to push through my workout. I would reccommend this to others.

Not for me

I bought this product as a natural test booster, but never felt the effects. I have always heard good things about Universal and figured this would be a great time to try this to give me an edge on my workouts. I honestly never felt an increase in strength or muscle gain. This product could possible work for someone else but it deff did not do much for me. I liked the fact that the pills came in easy to open individual bags and made it easy to carry anywhere.

Definitive results

This product delivers, plain and simple. No worries about placebo effect. This stuff puts the Muscle on and there are no adverse side effects to worry about. Put on 8 lbs of muscle in the last cycle and a large increase in max in most all areas of my lifting. I have used Stak several times with impressive results each time. I plan total it with Animal Test on my next cycle. Great product from Universal!!! With a long reputation of consistency.

strength gains in my hard to gain areas

Started back at the gym after a long period of time. I have always had a hard time improving my biceps and chest. Started taking animal stak and withing 2.5 weeks im lifting a lot more weight than i expected after such a short period. Already seeing results.

The best one

The first time I tried this stuff I fall in love, it really worked for me, built lean muscle and kept my gains after I finished this product.....after 8 weeks I took it again and worked even more, well I think I just add more weight to my sets and stuff, I DO highly recommend this product it really works and best yet I highly recommend buy it from best price nutrition, they are faster than other online you have to give it a try guys, won't be dissapointed.

Does What It Claims

This stuff does what it claims. I takes a week to start working.

Good product

I noticed a difference after the second week

animal works.

I have taken this of and on against other products Animal stack works for me. no placebo here, every time I cycle back on it my strength gains have always been through the roof!.

Great Product, Lots of potential

This is a great product. If you take Animal Stak and really hit the gym hard, eat right and sleep enough, you can really see some incredible gains in strength over just three weeks of using it. The only down side is that it requires taking seven pills a day every day for three weeks, but that is nothing compared to the gains you get from taking it.

Animal Stak is Stak2

Not sure why this is labeled as Stak2 on the site, it is the original Stak. False advertising. Anyways, seems to work pretty well so far, probably a 20% strength increase. We will see what happens in 3 weeks. RESPONSE: Universal removed the 2 from the labeling. This is indeed Stak2, just changed by the manufacturer, Universal Nutrition. Hope this clears things up. Thanks!
