GHK-Cu Dosage Guidance

(Already provided – use the earlier block or this refined version:) GHK-Cu is typically reconstituted with bacteriostatic water (BAC) and administered via subcutaneous injection or topical application, depending on your research protocol. The most commonly referenced laboratory dosage ranges are: • Daily injection: 1–2 mg per day for systemic effects such as tissue repair, collagen stimulation, and anti‑inflammatory studies. • Topical application: 1–3% GHK-Cu solution applied directly to skin or wound models, often combined with a neutral carrier gel. • Cycle length: Standard research cycles range from 4–6 weeks, followed by a 2‑week washout period to observe lasting effects and minimise receptor desensitisation in model organisms. Reconstitution example: A 50 mg vial reconstituted with 2 ml BAC water yields a 25 mg/ml solution. A 1 mg dose is drawn as 0.04 ml (4 units on a standard insulin syringe). Always store lyophilised GHK-Cu at −20 °C and reconstituted solutions at 2–8 °C, protected from light. Do not freeze after reconstitution. For research use only – not for human consumption.
