Beta-Alanyl-N-methyl-L-histidine

Anserine is a methylated dipeptide analog of carnosine found in high concentrations in avian and fish muscle. It shares carnosine's pH-buffering and antioxidant properties but shows superior blood-brain barrier penetration. Research highlights potential for cognitive decline prevention, reduction of amyloid-beta toxicity, and improved exercise performance. It is often studied alongside carnosine for synergistic effects.

FGF-21

FGF-21 is a 181-amino-acid endocrine fibroblast growth factor secreted by the liver under fasting conditions. It promotes fatty acid oxidation, ketogenesis, insulin sensitization, and thermogenesis in brown adipose tissue. Animal studies show it extends lifespan and reverses metabolic syndrome. Long-acting FGF-21 analogs and fusion proteins (efruxifermin, pegbelfermin) are in Phase 2–3 trials for NASH, type 2 diabetes, and dyslipidemia.

GHRH(1-29) · GRF 1-29 NH2

Sermorelin is a synthetic analog of the first 29 amino acids of endogenous growth hormone-releasing hormone (GHRH). It stimulates the pituitary to produce and secrete growth hormone in a pulsatile, physiologic manner. FDA-approved for GH deficiency in children, it is extensively researched in adults for body composition, sleep quality, and age-related GH decline.
