01Mechanism of Action
Parameter
GHK-Cu
Pinealon
Primary target
Copper-dependent enzymes (lysyl oxidase, SOD); regulator of >4000 human genesPickart 2018
Antioxidant defense + neuronal gene expression (proposed)Khavinson 2014
Pathway
Cu(II) delivery via GHK chelation → ↑collagen / elastin / GAG synthesis; ↓inflammatory cytokines; ↑hair follicle growth-factor signalingPickart 2018

05Administration Protocol
Parameter
GHK-Cu
Pinealon
1. Reconstitution
Add 1–2 mL bacteriostatic water to a 50 mg vial → 25–50 mg/mL. Use within 30 days, refrigerated.
Add 1–2 mL bacteriostatic water to 10 mg vial.
2. Injection site
SQ — local to the area of interest (face, scalp) for skin / hair indications. Rotate sites.
SQ — abdomen preferred.
3. Timing
Anytime; evening preferred. Topical: apply to clean dry skin.
Daily during cycle, any time.
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate, light-protected, ≤30 days.
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
5. Needle
30–31G, short (4–6 mm) for shallow SQ. Topical: clean fingertips, no needle.
29–31G, 4–8 mm insulin syringe.
06Stack Synergy
GHK-Cu
+ BPC-157
ModerateGHK-Cu drives ECM remodelling and copper-dependent enzymes; BPC-157 upregulates VEGFR2 angiogenesis and fibroblast migration. The pathways are non-overlapping and complementary — together they accelerate wound healing more than either alone in anecdotal protocols.
- GHK-Cu
- 1–2 mg SQ · daily near wound
- BPC-157
- 250–500 mcg SQ · daily near wound
- Primary benefit
- Combined ECM rebuilding + angiogenesis for tissue repair
Pinealon
+ Epitalon
ModeratePinealon (neuroprotection) + Epitalon (telomerase activation) form the canonical Khavinson "longevity stack" — both pineal-derived bioregulators with complementary axes. Pinealon supports neuronal antioxidant defense; Epitalon supports telomere maintenance. Anecdotally cycled together 1–2× per year.
- Pinealon
- 5–10 mg SQ · daily × 10 days
- Epitalon
- 5–10 mg SQ · daily × 10 days (overlap or alternate)
- Primary benefit
- Neuroprotection + telomere preservation
