Muscletech Amino Prototype 216 is a bodybuilding supplement aimed at boosting amino acids available in the body. Amino acids are necessary for the basic roles of protein. Bodybuilders typically take protein to supply energy and food to muscles. During the workout, small tears appear in muscles. With the right amount of amino acids and protein, these small tears grow into larger muscles. Muscletech lists places to buy Muscletech Amino Prototype 216.

Product Features

The majority of the ingredients in Muscletech Amino Prototype 216 are amino acids. There are many clinical references and huge numbers representing the positive effects of Prototype 216 on muscles. There are a few problems with these numbers and trials. None of the trial links is listed with the description. There are descriptions of the trial with the names of the institutions that completed the trials, but that is where the information stops.

One study references an increase in phenylalanine after taking Muscletech Amino Prototype 216. This is linked to the effect of the supplement in the description. Yes, phenylalanine is boosted by the supplement because it contains the ingredient L-phenylalanine.

As for the claims of immediate muscle growth, that is not a proven claim. Muscle growth is never immediate. It takes time for muscle tears to heal. Immediate growth is not something any stimulant, prescription medication or illegal substance can promise because it does not exist.

Muscletech Amino Prototype 216 sells for $23.99 on sale from the original price of $59.99 from GNC. The product may be on sale because it does not live up to the supplement claims.

  • Claims are a bit outrageous.

Building muscle requires a careful balance of protein, amino acids and exercise. Amino acid supplements are trusted by bodybuilders so there is no sense in making claims of immediate muscle growth when these claims are impossible to live up to. Bodybuilders should take the supplement about 15 minutes before a workout for optimal results.
