Epitalon · Epithalamin

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on the endogenous pineal peptide epithalamin. It is one of the most extensively studied longevity peptides, with Russian research demonstrating telomerase activation, telomere elongation, melatonin normalization, and extended lifespan in animal models. Long-term human studies show reduced all-cause mortality rates and improved biomarkers of aging.

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.

Thymalfasin · Tα1

Thymosin Alpha-1 is a naturally occurring 28-amino-acid peptide derived from thymosin fraction 5 of the thymus gland. Approved in over 35 countries for hepatitis B, hepatitis C, and as an immune adjuvant in cancer therapy, it enhances T-cell maturation, dendritic cell function, and NK cell activity. Research continues to expand into sepsis, COVID-19, autoimmune conditions, and vaccine response enhancement.
