Pretty good (Review by Timothy)

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. (Posted on 12/8/2015)

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.

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. (Posted on 7/5/2015)

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. (Posted on 3/11/2012)
Animal Stak is Stak2 (Review by Ken)
Recommend to a Friend
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! (Posted on 11/16/2010)
