Research summary

Super Human Blend combines nine amino acids historically used in performance and "GH-release" stacks: L-Arginine, L-Ornithine, L-Citrulline, L-Lysine, L-Glutamine, L-Proline, L-Taurine, L-Carnitine, and N-Acetylcysteine (NAC). Arginine, Ornithine, and Lysine are the classic combination studied for stimulating growth hormone release, but the strongest evidence for that effect comes from IV infusion research, not oral or the kind of standalone use this product represents — one study found intravenous arginine infusion raised growth hormone levels more than 20-fold in women. Oral-route evidence is far weaker: a controlled trial of oral arginine and lysine in older men found no significant change in spontaneous or GHRH-stimulated GH levels or IGF-1, and a broader review described oral arginine research overall as inconsistent, with most studies using small sample sizes. L-Carnitine has the most robust human trial base of the nine — the same 2020 meta-analysis of 43 randomized trials described on Fat Blaster's page found supplementation associated with an average 1.1 kg reduction in body weight and 1.2 kg reduction in fat mass.

L-Citrulline is studied for raising nitric oxide and supporting blood flow during exercise, but meta-analyses describe its ergogenic effects as modest and inconsistent: a 2019 meta-analysis of strength and power studies found a small pooled effect size of 0.20 with every individual study's confidence interval crossing the null, and a separate meta-analysis of nine endurance trials found no significant effect on time-to-exhaustion. N-Acetylcysteine has more supportive data for exercise fatigue specifically — an infusion study in eight endurance-trained men found NAC extended time to fatigue during high-intensity cycling by roughly 26% and raised muscle glutathione levels — though a larger 2017 meta-analysis pooling more heterogeneous studies found no clear performance benefit. Taurine's evidence is weaker still: a randomized trial giving 3 g/day to 55 trained men before resistance exercise found no measurable effect on antioxidant markers. Published research on L-Glutamine and L-Proline in this context is limited, and no study has evaluated these nine compounds combined in a single preparation.
