Where to inject GHK-Cu?

Published studies of GHK-Cu on its own used a cream or gel on the skin. The studies that injected it were hair clinics that injected the scalp with mixes that contained it. So no study says where on the body to inject it. If you mean a research vial injected under the skin, the body is the same, with the same four spots: the belly at least two inches from the belly button, the outer thigh, the back of the upper arm, and the upper outer buttock. That is not a finding about GHK-Cu. This is not a dose or a protocol. Full walkthrough at /injecting. Profile at /compounds/ghk-cu.

Part of injecting: sites, needles and safety. Subcutaneous vs intramuscular, site rotation, lipohypertrophy, needle length and gauge, vial hygiene at injection time, travel syringes, scar tissue, and when to stop and see a clinician. Full walkthrough at /injecting.
