Animal stak is crap...
Its a blend of a bunch of underdosed proH that can be called the newbie stack, because you can expect only 5lbs if you use it right. It will give you some pysch edge but no real qualtiy gains. For gains of 10-15 lbs stack individual proH at proper doses, dont take 5,6 in animal stack underdosed. I like universal, alot, but this is not a serious product.
