Research Comparison
AHK-Cu (Copper Tripeptide-3) vs Epitalon (Epithalon, AEDG)
A side-by-side research comparison of AHK-Cu (Copper Tripeptide-3) and Epitalon (Epithalon, AEDG) drawn from Cedar Peptides' peptide database records.
AHK-Cu (Copper Tripeptide-3)
AHK-Cu (Copper Tripeptide-3) is a synthetic copper-binding tripeptide composed of alanine, histidine, and lysine complexed with a divalent copper ion (Cu²⁺). It is structurally analogous to GHK-Cu, differing by a single amino acid substitution at the N-terminus, which contributes to its more targeted activity in dermal papilla cells and hair follicles. The compound is primarily investigated for its role in hair growth and skin regeneration. It has demonstrated the ability to stimulate follicular activity, enhance vascular signaling, and modulate pathways associated with hair miniaturization. In addition to hair-focused applications, AHK-Cu supports fibroblast activation and collagen synthesis, contributing to improved skin structure and repair.
Epitalon (Epithalon, AEDG)
Epitalon (Epithalon, AEDG) is a synthetic tetrapeptide derived from a naturally occurring pineal gland peptide, composed of four amino acids (Ala-Glu-Asp-Gly). It has been extensively studied in Russian research for its role in regulating aging processes, particularly through telomerase activation and circadian rhythm modulation. The peptide is associated with cellular longevity, improved sleep regulation via melatonin production, and systemic anti-aging effects. Research suggests it may influence gene expression, antioxidant systems, and cellular repair pathways, with effects observed even at extremely low (microgram-level) concentrations.
Reading a comparison
A comparison places two records side by side; it does not merge them. Each description above is drawn from that compound's own record, and the two were not necessarily characterised by the same methods, at the same time, or to the same level of detail. Before comparing any attribute, it is worth establishing that both records describe the substance you think they describe — names are not identifiers, and two entries sharing a name can differ in salt form, stereochemistry or the convention used to state a mass. Where a figure carries no method beside it, the comparison is between two reported numbers rather than between two measurements.
