The longevity.

Collagen peptides are short-chain amino acid sequences derived from enzymatic hydrolysis of native collagen (types I, II, and III).

Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) developed by Professor Vladimir Khavinson as a brain cortex bioregulator.

FOXO4-DRI is a synthetic D-amino acid retro-inverso peptide designed to selectively eliminate senescent cells — aged, dysfunctional cells that accumulate with age and drive chronic inflammation.

GHRH is the endogenous 44-amino acid hypothalamic peptide that drives pulsatile growth hormone secretion from the anterior pituitary.

Retinalamin is a polypeptide preparation isolated from bovine retinal tissue and registered as a pharmaceutical drug in Russia for retinal degenerative disease.

SS-31 (Elamipretide) is a mitochondria-targeted tetrapeptide that concentrates in the inner mitochondrial membrane.

Thymalin is a thymic peptide bioregulator developed by Vladimir Khavinson (the same researcher behind Epithalon) from bovine thymus extracts.

Thymosin Beta-4 is a 43-amino acid endogenous protein ubiquitously expressed in mammalian tissues, encoded by the TMSB4X gene.

Thymus Extract (Thymostimulin) is a partially purified preparation of thymic polypeptides derived from calf thymus tissue, first developed in Italy in 1976.

Ovagen is a synthetic tripeptide (Glu-Asp-Leu, EDL) sold as part of the Khavinson family of cytomaxes and cytogens and marketed as a liver and gastrointestinal bioregulator.

Testagen is a synthetic tetrapeptide (Lys-Glu-Asp-Gly, KEDG) sold as part of Professor Vladimir Khavinson's bioregulator range and marketed for testicular and male reproductive support.
