Muscularity from Beverly International:

Increase Fat Burning And Spare Lean Muscle Mass While Dieting!

Muscularity - By far the most advanced branch chain amino product on the market. Beverly International was the first again in combining several products together into one "ultimate product" combining branch chain aminos, chromium in the form of picolinate, zinc with the corresponding vitamins B-6 and B-12. The branch chains stimulate production of insulin which promotes amino acid intake by the muscles through promoting protein synthesis within muscle tissue.

The chromium makes insulin much more effective in its job of ferrying glucose across cellular membranes. The zinc is important in the pancreas production of insulin. The B vitamins 6 and 12 must be present for the system to effectively utilize the branch chains. Truly a product for all "serious body builders."
