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.
