used to be muscletech because of the ads. but now its biotest, those bastards refuse to deal with big distributors making it hard for me to order their stuff at work for personal use. now they make the GNC minimum order 200 fucking dollars up from 100 dollars. bitch asses. They make it impossible to get their damn products. i found one distributor who has their stuff though.....i do like their products.......just that they act like dicks.
