Epithalon vs GHK-Cu
Both feature in longevity research but operate through unrelated mechanisms — telomerase signalling vs copper-mediated repair and gene-expression modulation.
Mechanism
Epithalon (Ala-Glu-Asp-Gly) is reported in research literature to upregulate telomerase activity. GHK-Cu is a copper-binding tripeptide that influences gene expression related to tissue repair, antioxidant defence and dermal remodelling.
Research focus
Epithalon research has centred on pineal/telomere-related endpoints. GHK-Cu research spans wound healing, dermal repair, hair follicle biology, and broad gene-expression effects.
Half-life & administration in research
Both are typically administered subcutaneously in research protocols. Half-lives are short (minutes); studies often dose intermittently across cycles.
Frequently asked questions
Are these both longevity peptides?+
Both appear in longevity research, but they work on very different pathways. Epithalon is studied for telomerase activity; GHK-Cu is studied for copper-mediated tissue repair and gene-expression effects.
Which has stronger human data?+
GHK-Cu has the larger published literature, particularly in dermatology and wound-healing research. Epithalon's human data is more limited and largely Russian-language.
