GHK-Cu 100 mg Calculator
Unit conversion for a reconstituted 100 mg vial: mg → mcg/mL → mL → U-100 syringe units. Nothing is pre-filled or recommended.
Regulatory status
Injectable GHK-Cu is not approved by the FDA for any human use, and there is no FDA-approved dose. Products sold as "research peptides" are not FDA-approved drugs. FDA has stated: "Compounded injectable drugs containing GHK-Cu may pose risk for immunogenicity due to the potential for aggregation and peptide-related impurities."
Calculator
100 mg vial × diluent volume: concentration table
| Diluent | mg/mL | mcg/mL | mcg per U-100 unit |
|---|---|---|---|
| 0.5 mL | 200 | 200,000 | 2000 |
| 1 mL | 100 | 100,000 | 1000 |
| 1.5 mL | 66.7 | 66,667 | 666.7 |
| 2 mL | 50 | 50,000 | 500 |
| 2.5 mL | 40 | 40,000 | 400 |
| 3 mL | 33.3 | 33,333 | 333.3 |
| 4 mL | 25 | 25,000 | 250 |
| 5 mL | 20 | 20,000 | 200 |
This table is pure arithmetic (concentration per volume), not a dosing chart. Arithmetic example only (not a dose): 100 mg in 2 mL = 50,000 mcg/mL, so one U-100 unit holds 500 mcg.
How the math works
- Vial amount in mcg = mg × 1,000.
- Concentration (mcg/mL) = vial mcg ÷ diluent mL.
- Volume (mL) = amount entered ÷ concentration.
- U-100 units = mL × 100.
FAQ
Does this page give a GHK-Cu dosage or dosage chart?
No. This page is a calculation tool only. It converts the vial amount, diluent volume and amount you enter into concentration and U-100 syringe units. It does not suggest any dose, schedule or protocol for GHK-Cu.
Is GHK-Cu FDA-approved?
Injectable GHK-Cu is not approved by the FDA for any human use, and there is no FDA-approved dose. Products sold as "research peptides" are not FDA-approved drugs. FDA has stated: "Compounded injectable drugs containing GHK-Cu may pose risk for immunogenicity due to the potential for aggregation and peptide-related impurities."
What is the concentration of a 100 mg vial?
It depends on the diluent volume: concentration (mcg/mL) = 100000 ÷ mL of diluent. For example, 100 mg in 2 mL = 50,000 mcg/mL, so each U-100 unit holds 500 mcg. See the table above for other volumes.
