Gaining weight and getting big isn’t easy – you need a lot of muscle to get the kind of serious size that gets serious attention. To get this kind of muscle mass, you have to continually feed your body calories, proteins, and carbohydrates; if you don’t, you won’t move even an inch on the scale.

But make no mistake: not just any proteins and carbohydrates will do. To gain the kind of thick, dense, ripped mass that splits shirts and turns heads – to grow complete mass – you need high-quality, anabolic, championship-grade calories, proteins, and carbohydrates. And, you need them to get to your muscles at the right times  right now and over the course of the entire day.

COMPLETE MASS 600 by Optimum Health brings together the highest-quality, anabolic, championship-grade calories, proteins, and carbohydrates in one easy-to-use, highly-effective formula. By combining a scientifically formulated professional-caliber blend of time-released proteins and an anabolic carb matrix that give you 600 growth-triggering calories per serving, COMPLETE MASS 600 builds serious size.

The time-released, professional-strength protein blend in COMPLETE MASS 600 contains a full 50 grams of highly bioavailable fast, medium and slow-acting proteins that supply your hard-working muscles with a steady stream of growth-triggering amino acids for up to five continuous hours. As a result, you get an all-day positive nitrogen balance that prevents muscle wasting and that triggers constant muscle growth!
