GHK-Cu is the copper complex of a naturally occurring tripeptide studied across dermatology, wound-healing, and cosmetic science for decades. It is analytically tractable but frequently sold without adequate identity or copper-content documentation.
Angiotensin (1-7) is a heptapeptide metabolite of the renin-angiotensin system studied as a counter-regulatory arm opposing Ang II signaling, with cardiovascular and fibrosis research literature.
Cartalax is an Ala-Glu-Asp tripeptide bioregulator discussed in cartilage and connective-tissue aging research. It shares sequence motifs with other Khavinson tetrapeptides but is a distinct catalog entity requiring explicit identity proof.
Cortagen is an Ala-Glu-Asp-His tetrapeptide bioregulator studied in adrenal cortex and stress-axis aging research. It is among the organ-targeted Khavinson peptides where catalog naming and sequence confirmation matter.
Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) associated with telomerase and pineal-aging research from the Khavinson bioregulator literature. Catalog material is analytically simple but requires batch identity confirmation.
FOXO4-DRI is a D-retro-inverso peptide designed to disrupt FOXO4–p53 interactions in senescent cells. It sits at the intersection of senolytic research and catalog peptide supply, where sequence fidelity is critical.
Glutathione is the central intracellular tripeptide antioxidant studied across redox biology, detoxification, and aging research. Catalog supply includes reduced (GSH) and oxidized (GSSG) forms requiring explicit specification.
Humanin is a 24-amino-acid peptide first identified in surviving neurons of Alzheimer's disease tissue. It is studied for cytoprotective, metabolic, and inflammatory endpoints across mitochondrial peptide research.
MOTS-c is a 16-residue peptide encoded within mitochondrial 12S rRNA, studied for metabolic regulation and exercise-mimetic effects in rodent models. Endogenous production and exogenous supply are distinct research contexts.
Ovagen is a Glu-Asp-Leu tetrapeptide bioregulator associated with liver and hepatocyte aging research in the Khavinson literature. Catalog supply should be verified as the defined tetrapeptide, not an undisclosed liver extract.
Pinealon is a Glu-Asp-Arg tripeptide bioregulator studied in neuroprotective and brain-aging research from the Khavinson literature. It is analytically tractable but often sold without adequate batch characterization.
SS-31 (elamipretide) is a mitochondria-targeted tetrapeptide studied in mitochondrial dysfunction, heart failure, and rare disease research programs with published clinical-stage data — distinct from most catalog-only longevity peptides.
Thymalin refers to a thymus-derived peptide bioregulator preparation studied in immune aging and thymic involution research. Catalog products vary between defined peptides and complex extracts — identity scope must be explicit.
Vesugen is a Lys-Glu-Asp tripeptide bioregulator studied in vascular and endothelial aging research from the Khavinson catalog. It is frequently discussed alongside cardiovascular recovery peptides but occupies a separate evidence base.
