Powerful Stuff

Posted by HawaiianViking on Sep 05, 2012 | Verified Purchase

Universal Nutrition, Animal Stak, Testosterone Optimizers are powerful: I've noticed a significant improvement in my workouts while I've been taking this product. It's a good alternative to dangerous and/or illegal substances, but it's not without its drawbacks: This product is expensive. For 21 Packs, it's not the best value, and you'll probably need more than just 21 Packs to reach and maintain your training goals. For me personally, this product has given me a headache, upset my stomach and has been taxing to my liver, so it's not the easiest regimen to maintain. Still, it's probably worth it, since it is that effective.

Thanks for your feedback!

Good for balancing/boosting test levels

Found that this is a bit expensive for what you get, 21 days of normalized/boosted testosterone, but it definitely helps. Probably need to go through 2-3 Staks to get to where you want to be. This is a sloooow process towards getting the chiseled bod you want, but arguably a lot safer than the alternatives. I'd say if you are going for hardcore muscle gaining, this is relatively mild. Combined with lots of protein and creatine, maybe some NO2 or something like Jack3d, you should expect to see good results over a few months.
