GHK-Cu reconstitution calculator
copper tripeptide GHK-Cu
GHK-Cu is a naturally occurring copper-binding tripeptide studied mostly for skin repair and wound healing. Cosmetic (topical) use is mainstream; injectable use is a research-chemical gray zone. Note the unusually large vial sizes - GHK-Cu math involves bigger numbers than most peptides.

This tool converts the numbers you enter (dose ÷ concentration = volume). It never suggests a dose. The FDA has documented hospitalizations caused by mg / ml / unit conversion errors with vial-and-syringe products - if the readout surprises you, stop and verify with your prescriber or pharmacist.
Questions people actually search
Why are GHK-Cu vials so much larger than other peptides?
Amounts discussed in research are in the milligram range (often 1-2 mg or more per administration), a thousand times larger than typical BPC-157 amounts in mcg. Vials are sized accordingly at 50-100 mg. The math is identical - only the magnitudes change.
Is topical GHK-Cu the same as injectable?
The molecule is the same; the regulatory status is not. Topical GHK-Cu in cosmetics is legal and widespread. Injectable GHK-Cu has no approved form and is sold under research-use-only labels, with the purity and legality caveats that entails.
Does GHK-Cu need bacteriostatic water?
For a multi-dose vial punctured repeatedly, bacteriostatic water is the standard diluent discussed in compounding literature because the benzyl alcohol suppresses bacterial growth. Single-use preparations may use sterile water.
