GHK-Cu (copper peptide) is a research peptide used topically or reconstituted. It is not FDA approved. This tool does the mixing and unit math for the numbers you enter.
Informational only. Not medical advice. Always double-check every dose with a licensed provider.
A 50 mg vial with 5 mL of water is 10.00 mg/mL. A 2 mg dose is 0.20 mL, which reads as 20 units on a U-100 syringe, and the vial holds 25 doses. These are example numbers, change them to yours.
Divide the GHK-Cu in the vial (mg) by the bacteriostatic water you added (mL) to get the strength in mg/mL. Divide your target dose by that strength to get the mL to draw, then multiply by 100 for the units on a U-100 syringe. For example, a 50 mg vial with 5 mL of water is 10.00 mg/mL, so a 2 mg dose is 0.20 mL, which is 20 units.
That is your choice, and it only changes the strength, not how much GHK-Cu you have. More water makes it weaker (more units per dose); less water makes it stronger. This tool shows the units for whatever amount you enter.
It depends on your vial strength and your dose. With the example above (50 mg in 5 mL, 2 mg dose) you would draw 20 units on a U-100 syringe. Enter your own numbers to see yours.
It depends on the exact product. Some peptides and GLP-1 medicines are FDA approved and some are not. See our plain guide on what peptides are FDA approved.
