GHK-Cu Waitlist // Fitish RX
// New from Fitish RX Two formats. One molecule.

The peptide
your body
makes less of
every year.

GHK-Cu is a copper-binding peptide your body produces naturally, and produces less of as you age. Now arriving in two prescription-grade formats, oral sublingual tablets and a compounded face cream. Be the first to know when it goes live.

GHK-Cu by Fitish
GHK-Cu // Wellness that wins.

Your body's
repair signal,
quieting with age.

GHK-Cu is built from three amino acids (glycine, histidine, lysine) bound to a copper ion. It signals your skin and tissue cells to repair, regenerate, and behave younger. Plasma levels drop sharply with age, tracking closely with visible aging, slower wound healing, and weaker collagen.

Why ours wins.

You can buy a copper peptide serum at Sephora. Here is the difference.

Concentration

OTC products run 0.5 to 1%. Compounded prescription formulations are dosed at clinically meaningful concentrations matched to each patient's needs.

Purity

Prescription compounding follows USP 795 pharmaceutical standards. OTC operates under cosmetic regulations, which are dramatically less strict.

Provider review

Every prescription is reviewed by a licensed provider who screens for contraindications before approval. No cosmetic product offers that.
