Research Comparison
AHK-Cu (Copper Tripeptide-3) vs Pinealon (EDR)
A side-by-side research comparison of AHK-Cu (Copper Tripeptide-3) and Pinealon (EDR) drawn from Cobalt 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.
Pinealon (EDR)
Pinealon (Glu-Asp-Arg/EDR) is a synthetic tripeptide bioregulator developed in Russia that demonstrates unique DNA-interaction capabilities for neuroprotection and cognitive enhancement. Research suggests benefits for traumatic brain injury recovery, age-related cognitive decline, and cellular aging processes through direct gene expression modulation. Studies have shown that Pinealon exerts neuroprotective effects through MAPK/ERK pathway modulation, reduced neuroinflammation, and enhanced NMDA receptor expression in hippocampal regions. Its ability to directly interact with DNA and influence gene expression makes it distinct from other peptide bioregulators.
