Skin & Collagen

Compounds studied in collagen synthesis, skin elasticity, wound healing at the dermal level, or cosmetic applications.

AHK-Cu AHK-Cu is a synthetic copper-chelating tripeptide (Ala-His-Lys) used in cosmetic formulations and studied in a single published laboratory model for effects on hair follicle growth. View research notes → Cartalax Cartalax is a synthetic tripeptide (Ala-Glu-Asp) developed by Russian gerontology researchers. In vitro studies have examined its effects on cellular aging markers across several tissue types. View research notes → Epithalon Epithalon is the most-studied synthetic tetrapeptide in longevity research. The evidence centers on telomere biology and pineal gland function. Here is what the published literature actually shows. View research notes → GHK-Cu GHK-Cu is one of the most-studied peptides in skin aging and collagen research. Here is what the published evidence actually looks like. View research notes → GHK-Cu + Epithalon: Anti-Aging Research GHK-Cu and Epithalon address two distinct layers of the aging process. GHK-Cu has one of the largest in vitro evidence bases in skin and collagen research. Epithalon has been studied for telomere elongation and longevity at the cellular level. This page covers what the research actually shows for each compound and what they cost per milligram. View research notes → GLOW Blend (GHK-Cu + BPC-157 + TB-500) A pre-formulated research blend combining GHK-Cu, BPC-157, and TB-500 in a single vial. Here is what the research on each component looks like and what the published evidence actually shows. View research notes → Glutathione Glutathione is the body's primary intracellular antioxidant — a tripeptide it manufactures itself. Levels decline with age and chronic disease, and research has examined whether supplementation can reverse that decline. View research notes → KLOW Blend (GHK-Cu + BPC-157 + TB-500 + KPV) A four-peptide research blend combining GHK-Cu, BPC-157, TB-500, and KPV in one vial. Here is what the published evidence looks like for each component and how KLOW differs from the three-peptide GLOW formulation. View research notes → Melanotan Melanotan is the informal name for a family of synthetic alpha-MSH analogs originally developed for sunless tanning research. Two pharmaceutical descendants, afamelanotide (Scenesse) and bremelanotide (Vyleesi), are now FDA-approved for specific medical indications. View research notes → Melanotan II Melanotan II is a synthetic alpha-MSH analog studied for skin pigmentation, sexual function, and melanocortin receptor pharmacology. It is the precursor compound that led to the development of PT-141 (bremelanotide), which is FDA-approved for women's sexual dysfunction. View research notes →
