About GHK-Cu

A copper-binding tripeptide studied extensively for skin regeneration, hair follicle health, and wound healing.

Research dose ranges

  • Dose: 1000–2000 mcg per administration
  • Frequency: 1× per day
  • Route: subcutaneous
  • Half-life: ~4 hours
  • Cycle: 8 weeks on / 4 off

GHK-Cu is most commonly studied topically. Injectable research protocols typically use 1–2 mg subcutaneously per administration.

Storage

Sensitive to light. Store lyophilized vials at 2–8°C in dark conditions; refrigerate reconstituted solution.

GHK-Cu calculator FAQ

How do I use the GHK-Cu calculator?+

Confirm your vial size in mg (default 50), set the diluent volume in mL (default 5), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard GHK-Cu reconstitution?+

Most GHK-Cu research protocols reconstitute a 50 mg vial with 5 mL of bacteriostatic water, yielding 10000 mcg/mL.

What syringe should I use for GHK-Cu?+

U-100 insulin syringes are standard for GHK-Cu subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the GHK-Cu calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
