GHK-Cu
Reconstitution
GHK-Cu is naturally acidic and can sting going in. Filling to the full 3 mL dilutes it as much as the vial allows, which noticeably reduces the burn, so the larger fill is usually preferred. Some people co-mix it with BPC-157 to buffer the sting further.
Reconstitute with bacteriostatic water, adding it slowly down the side of the vial.
Swirl gently until dissolved. Do not shake.
The finished solution will have a faint blue tint. That is the copper and is completely normal.
Once fully mixed it should be clear, not cloudy.

Suggested Protocol
1 mg to 2 mg per day, once daily or split morning and evening
At a 3 mL fill on the 50 mg vial (about 16.7 mg/mL), 1 mg is a 0.06 mL draw (6 units) and 2 mg is 0.12 mL (12 units)
The 100 mg vial at 3 mL is twice as concentrated, so halve those draws
A 5 days on, 2 off pattern is common
GHK-Cu works through gene expression, so visible skin and hair changes take weeks
Commit to a 30 day cycle (then 14 days off), ideally 8 to 12 weeks total, before judging it
It is acidic and can sting, so dilute more and push slowly
Dosing Detail
Injectable use commonly lands around 1 mg to 2 mg per day.
A 5 days on, 2 days off pattern is popular.
Many run a topical version alongside for skin and hair.
Based on 3 mL of bac water.

Duration
Run in 30-day blocks, then take a short break before the next round.
Notes
Copper peptides sting because the solution is acidic. More bac water and a slow push both help.
Popular for skin firmness, fine lines, wound healing and hair quality.
Do not mix in the same syringe as other peptides unless you mean to, since copper can react. BPC-157 is the common deliberate exception.
Inject into a well-rotated subcutaneous site.
Storage & Handling
Keep the powdered (lyophilized) vial in a cool, dark place. Refrigerate it for longer-term storage before mixing.
Once reconstituted and properly stored (refrigerated at 2 to 8°C and kept out of direct light), use the vial within 90 days.
Do not freeze a reconstituted vial, and keep it away from heat and sunlight.
If the solution turns cloudy, develops floating particles, or shows any other sign of degradation, stop using that vial.
A faint blue tint is normal for copper peptides. That colour is the copper itself, not degradation.
