Xtreme Growth Factor - Lean Mass Weight Gainer. Pack on lean muscle without the fat!

AST MUSCLE-XGF is a potent mass gaining formula designed for solid lean muscle growth without fat gain.

Typical weight gainers get their calories mostly from cheap carbohydrates. Excessive carbohydrates only provide "empty" calories. The weight you gain from these sub par products is mostly fat. Gaining lean muscle mass is more than just slamming "empty" calories. That’s why MUSCLE-XGF delivers you a precision formulation designed to support solid, lean mass weight gain without adding fat.

AST Muscle XGF contains MyoGen-8

MyoGen-8 is our new multi-release, 8-stage, nitrogen-rich protein hybrid – consisting of 8 precision coalesced protein composites designed for slow, medium, and fast nitrogen delivery. You get fast and long lasting nitrogen delivery for immediate and extended protein synthesis. No other weight gainer gives you such a comprehensive protein formula.
