yea, Basically they just marketed the products to different target markets, focusing on that groups wants and needs. Muscletech is your normal bodybuilding supps. line for those willing to spend money to get a realitively good product that hits all the bases of gaining muscle and staying lean. Six Star is pretty much their budget line. In my opinion it's marketed for high school kids because they tend to state the words get jacked or get ripped in 3 weeks. Something every teenage guy (including me

) wants to hear. Finally M.A.P was put out to grab the attention of the hardcore lifters looking to spare no expense. This is evident when they use such words as "test subject" and "side effects" to describe an insane way of supplementation. Hope this helps!
