Like Chris said, generally if you're using NATURAL products, then you are not going to test positive for drugs etc. in a sports drug test. In saying that, you should check the ingredients in ANY and EVERY product that you are considering using and check with your sporting organization re 'allowed' and 'banned' substances, since not all of them follow WADA - such as the NCAA, which has their own list, and there are a few substances on there that are not banned in anything else.
I'm starting a stack in two weeks and I have asgt, alpha t2, oep, postal, glycobol and all the other basics
OP, depends on goals, but you can't go wrong with any of LG's products.
For a synergistic, fat burning, Pre workout stack check out T-2 + ASGT
PM me with any order questions and concerns
Natty I'm so looking forward to that stack. :-)
