GHK-Cu Reconstitution Calculator
Also listed as GHK Cu · GHKCu · copper peptide · glycyl-histidyl-lysine copper
GHK-Cu ships lyophilized in 50mg, 100mg vials. Enter the vial size, the bacteriostatic water you add, and a target analyte mass to get the solution concentration, the aliquot volume in mL and µL, and the marks it reaches on a U-100 graduated syringe. Laboratory reconstitution math only.
U-100 scale — 100 graduation marks per mL.

GHK-Cu reconstitution chart
Example: a 50mg GHK-Cu vial reconstituted with 2 mL of bacteriostatic water is 25 mg/mL (25,000 mcg/mL), and each mark on a U-100 graduated syringe holds 250 mcg. Every vial size and diluent volume:
| Vial | Bac water | mg/mL | mcg/mL | mcg per U-100 mark |
|---|---|---|---|---|
| 50mg | 1 mL | 50 | 50,000 | 500 |
| 50mg | 2 mL | 25 | 25,000 | 250 |
| 50mg | 3 mL | 16.67 | 16,667 | 166.67 |
| 100mg | 1 mL | 100 | 100,000 | 1,000 |
| 100mg | 2 mL | 50 | 50,000 | 500 |
| 100mg | 3 mL | 33.33 | 33,333 | 333.33 |

GHK-Cu calculator — frequently asked questions
There is no single required volume — the diluent sets the concentration, not the amount of GHK-Cu in the vial. A 50mg vial (50 mg) gives 50 mg/mL with 1 mL of bacteriostatic water, 25 mg/mL with 2 mL, and 16.67 mg/mL with 3 mL. More diluent makes each aliquot a larger, more precisely measurable volume.
Concentration is the lyophilized mass divided by the diluent volume. A 100mg GHK-Cu vial reconstituted with 2 mL of bacteriostatic water is 50 mg/mL (50,000 mcg/mL). GHK-Cu is supplied in 50mg, 100mg vials; the chart on this page lists each size at 1, 2 and 3 mL.
A U-100 graduated syringe has 100 marks per milliliter, so each mark is 0.01 mL. At 25 mg/mL (a 50mg vial with 2 mL) each mark holds 250 mcg; multiply the mcg-per-mark figure by the number of marks to find the mass in a measured volume. These are volume-measurement figures, not dosing or administration instructions.
Lyophilized GHK-Cu is stored at −20°C long-term (2–8°C short-term), protected from light. Once reconstituted with bacteriostatic water, the solution is typically held at 2–8°C and used within the window appropriate to the study. Swirl gently to dissolve — never shake — and minimize freeze–thaw cycles.
No. It performs in-vitro laboratory reconstitution math for a research-use-only reference standard. It is not medical, dosing, or clinical guidance and is not instructions for administration.
