Product Overview


  • Anabolic Liquid
  • Dietary Supplement

The Science Behind The Size:

  • Product: a fast absorbing anabolic liquid amino acid that has, per serving, 15 grams (15,000 mg) of high quality branched chain, peptide-bonded, and free amino acids; stress B-complex vitamins; energizing complex carbohydrates; and pure crystalline fructose.
  • Result: protein in its most easily digested, absorbable and utilizable form to maximize muscle growth and optimize protein synthesis.
  • Science: research shows that when taken orally, peptide-bonded amino acids increase nitrogen retention better than free form amino acid mixtures for optimum muscle growth.

Suggested Use

As a quick-acting, easily digested amino acid, take three (3) tablespoons daily, or as recommended by a professional trainer. Amino Fuel may also be taken with meals, between meals, as an anabolic acid before workouts, or after physical activity. For best results, use as part of a low-fat diet and exercise program.

Good stuff with bad taste

Posted by 4788781836400525595 on May 28, 2014

It's a good product with the necessary needfuls in its ingredients list. But it's very gluey and sticky, which makes things a little messy at times. The taste is horrendous. Not very portable given the sticky gluey content which makes it hard to displace into other containers with minimal wastage. The original bottle is a little heavy and clumbersome. Still, a good liquid form of Amino.
