Sermorelin
LongevityGHRH analog (first 29 amino acids of human GHRH). Stimulates endogenous growth hormone release. Approved for pediatric GH deficiency, widely used off-label in adults.
SS-31 (Elamipretide)
LongevityStealth BioTherapeutics' mitochondria-targeted tetrapeptide. Binds cardiolipin in the inner mitochondrial membrane and improves electron transport chain efficiency. Multiple Phase 3 trials in genetic mitochondrial diseases (Barth syndrome, primary mitochondrial myopathy) with mixed regulatory outcomes.
NAD+ (Nicotinamide Adenine Dinucleotide)
LongevityCoenzyme essential for cellular energy production and DNA repair (NOT a peptide — it's a nucleotide). Available as IV infusion, intranasal, and oral precursors (NR, NMN). Heavily discussed in longevity communities. Direct NAD+ supplementation has weak human RCT support; precursors have somewhat better data.
Epitalon
LongevityTetrapeptide studied primarily in Russian gerontology research for telomerase modulation and pineal function.
