Epithalon vs GHK-Cu: Best Anti-Aging Peptide?
Comparing epithalon (telomere extension, telomerase activation) vs GHK-Cu (gene expression restoration, collagen, wound healing) for anti-aging research.
Epithalon
Epitalon
Research OnlyGHK-Cu
GHK-Copper
Research OnlyEpithalon
A synthetic tetrapeptide that activates telomerase, the enzyme responsible for lengthening telomeres. One of the only compounds with robust evidence for telomere extension in humans.
GHK-Cu
A naturally occurring copper-binding tripeptide that declines with age. Promotes skin rejuvenation, wound healing, hair growth, and anti-inflammatory effects. One of the most studied anti-aging peptides.

Our Verdict
Winner: Both serve different goals
Epithalon targets the cellular aging mechanism (telomere shortening) and has the only human data showing actual telomere lengthening. GHK-Cu works at the gene expression level, restoring youthful patterns of tissue maintenance, collagen production, and inflammation control. They complement each other: Epithalon targets the clock; GHK-Cu targets the downstream effects of aging.
