Not a fan of muscle-tech products. Usually overpriced, nasty tasting, and lacking in nutrients compared to the competition.
Personally, I use products from MHP, mainly Probolic-SR and "Up your Mass" (Silly name, I know) Both are more potent (28g of protein for Pro. & 60g for UYM), cheaper than anything from Muscle-Tech, and taste pretty damn good.
Th only thing Muscle-Tech has is a good marketing campaign, their products fail compared to the competition.
