Caffeine and various metabolic extracts such as green coffee and cayenne are utilized to support thermogenesis and energy expenditure. The inclusion of L-carnitine L-tartrate at a very low dose provides minimal support for recovery or muscle protein synthesis.

Primary focus on weight management results in limited alignment with the specific goal of muscle hypertrophy. Formula composition lacks the key ergogenics and amino acids required to meaningfully drive strength gains.
