— Mechanism / 01

Three mechanisms. One molecule.

GHK-Cu is the copper-tripeptide complex that drives every credible "peptide skincare" claim. Collagen synthesis, hair follicle activity, hyaluronic-acid signaling — three mechanisms with three decades of dermatology literature underneath them.

Collagen synthesis

GHK-Cu upregulates type I and type III collagen, stimulating fibroblasts to rebuild the dermal matrix.

Effect · Primary

Hair follicle activity

Activates dermal papilla cells and prolongs anagen — the published mechanism behind copper peptide hair claims.

Effect · Secondary

Antioxidant signaling

Suppresses inflammatory and oxidative pathways at the dermal level — the visible-skin part most users notice first.

Effect · System
— Reference protocol / 02

Trial-aligned titration ladder.

This is the published Phase 2 escalation pattern, not a dosing recommendation. Adjust under qualified guidance based on tolerability and research goals. Open the dosing calculator below to convert mg to units.

Topical mg

Reconstituted at 1mg/mL, applied AM/PM after cleanser. Most cosmetic-research protocols.

Subcutaneous1–2 mg

Twice-weekly SC for systemic-skin protocols. Lower doses than recovery peptides.

Combination1+topical

Stack subq with topical for skin, hair, and connective-tissue protocols.

— What ships / 03

The complete research kit.

Every Element MD box ships with everything needed to reconstitute and run the protocol. We don't fragment the workflow into upsells — the kit is the kit.

One vial replaced three protocols.

Was running GHK + BPC separately. The pre-blend cleaned up my schedule and the outcomes hold.

Texture, hairline, glow. All three.

Twelve weeks in. The synergy is real and the convenience matters.

Element MD's blend ratio is identical batch over batch.

Tested with my own contract lab — ratios consistent across two reorders. That is real QC.

Switched from a compounded source. Half the cost, twice the documentation.

Element MD is the one whose batch consistency I have not had to question. Reorder is automated and the COA on top of every box matches the database.

— Common questions / 05

Before you order. Before you reconstitute.

Topical vs subq?
Topical is best for localized skin/hair claims; subq is for systemic protocols. Many run both.
Why copper?
The copper ion is the active centre — it gates the redox + collagen mechanism. Plain GHK without copper does not behave the same way.
Dilution for topical?
Most protocols dilute to 1–2mg/mL in saline or distilled water. Apply post-cleanse.
Independent COA?
Every batch ISO-17025 tested.
What's your cold-chain process?
Lyophilized peptide is stable at room temperature for short transit, but we ship every order with insulated mailers and gel packs sized to the destination. Average arrival temperature on cross-country routes is 4.7°C.
How do I cancel a subscription?
From your account dashboard, in two clicks. No retention call, no email loop. Pause, skip, or cancel any time before the next ship date.
