So I'm on a mission to get the best body I can by this summer and would love to hear some input on what kind of workout supplement would give me the best results. I'm not looking to get body builder huge or anything, I just want to get sculpted. Lean with some definition. I'm on a diet and have already lost some weight, just need some tips on the most effective way to gain some muscle. P.S. I would rather these products be available at GNC so I don't have to order it online. Thanks!
