What is GHK-Cu / Epithalon?
(a copper peptide with a pineal peptide)
Two peptides that address aging at different levels: GHK-Cu at the tissue level, signaling collagen, elastin and repair; Epithalon at the cellular level, supporting telomerase and the pineal gland's melatonin rhythm. Together they are the core of many longevity protocols, and one vial means one injection.

Each peptide has its own evidence base; the combination itself has not been studied in trials. Prescribed off-label at your physician's discretion.
How skin and longevity peptides work

Day 1
A US-licensed physician reviews your goals and history and sets your dose and course. The kit includes everything you need.

Week 1–2
A small subcutaneous injection, daily or on the course your physician sets. Sleep and skin hydration are often the first things people notice.

Month 1–2
Collagen signaling takes weeks to show: skin texture and firmness, and recovery after training, tend to change next.

Month 3–6
Changes consolidate with consistent use. Your physician checks in, adjusts the dose and decides on the next course.

Beyond
Longevity is a long game: sleep, movement, nutrition and sun protection do most of the work. Peptides support them.

The science of skin and longevity peptides
GHK-Cu stimulates collagen and elastin synthesis and wound repair; Epithalon lengthens telomeres in human cell lines and supports melatonin production.
Neither has large modern human trials for longevity outcomes. Your physician explains what is established and what is early before prescribing.
