Formulation
Formula re: Contains
Metabolic Nutrition identified these structure flaws with free-form glutamine and solved the problem by utilizing chemical and enzymatic peptide bonding to develop T.A.G., the first di-peptide "stable" glutamine engineered to specifically target muscle for maximum muscle repair and recovery.
Formula re: Contains
T.A.G. contains both Trans-Alanyl-Glutamine and L-Alanyl-L-Glutamine (Sustamine) to offer the only duel di-peptide Glutamine structure that is stable in both liquid & high temperature, yet easy to absorb and assimilate into the bloodstream for direct infusion into the muscle cells.
Formula re: Type
In addition, T.A.G. also supports the body's immune system, increases protein synthesis and growth hormone release; making it a critical supplement in any athlete's regimen.
Formula re: Contains
Trans Alanyl Glutamine

Brand IP Statement(s) re: (c), (TM), (SM)
T.A.G. is ideal for any consumer who demands superior quality, uncompromising results, and is looking to improve overall health, increase muscle repair, and maximize physical enhancement…guaranteed!
General Statements: All Other Content
Everyone wants to build a great physique they are proud of, as well as admired by others. Problem is, even though you put in the time and effort with strenuous workouts and strict dieting, without proper recovery you will never see the gains you work so hard for. It's common to use L-Glutamine to assist in recovery from working out, but science has proven that the body is predisposed to use regular L-Glutamine for intestinal health and not for muscle tissue repair. Regular glutamine also degrades in liquids and is unstable at higher temperatures.
General Statements: All Other Content
T.A.G. works by preventing the loss of muscle glutamine during exercise, (i.e. muscle loss), supplying the critical glutamine needed by the muscle intra and post workout.
