Reconstitution calculator · GHK-Cu
GHK-Cu reconstitution calculator.
Work out the concentration of a reconstituted GHK-Cu vial. Presets match the 50 mg / 100 mg formats we stock, and the reference table below is calculated for those exact vials. Research use only.
This tool reports concentration only. It is not dosing guidance, and nothing here is for human use.
GHK-Cu concentration reference table
Every combination of the GHK-Cu vial sizes we stock and the bacteriostatic water volumes people most often add.
| Vial | BAC water | Concentration | Per 100 µL aliquot |
|---|---|---|---|
| 50 mg | 1 ml | 50 mg/ml | 5 mg (5,000 mcg) |
| 50 mg | 2 ml | 25 mg/ml | 2.5 mg (2,500 mcg) |
| 50 mg | 3 ml | 16.667 mg/ml | 1.667 mg (1,667 mcg) |
| 50 mg | 5 ml | 10 mg/ml | 1 mg (1,000 mcg) |
| 100 mg | 1 ml | 100 mg/ml | 10 mg (10,000 mcg) |
| 100 mg | 2 ml | 50 mg/ml | 5 mg (5,000 mcg) |
| 100 mg | 3 ml | 33.333 mg/ml | 3.333 mg (3,333 mcg) |
| 100 mg | 5 ml | 20 mg/ml | 2 mg (2,000 mcg) |
How the calculation works
Concentration is the mass of peptide divided by the volume of solvent. A vial holding 5 mg reconstituted with 2 ml of bacteriostatic water gives 2.5 mg/ml, so a 100 µL aliquot contains 0.25 mg. The powder itself adds no meaningful volume at these masses, which is why the water volume alone sets the concentration.
Handling in the Vietnamese climate
Sealed lyophilized vials are stable at room temperature in transit, which is why the material ships dry rather than cold. Once reconstituted, the solution is kept refrigerated and shielded from light. Bacteriostatic water is the usual solvent because the benzyl alcohol in it lets a vial be entered more than once.
What is GHK-Cu?
A copper-carrying tripeptide that occurs naturally in human plasma.
GHK-Cu is one of the few compounds in this catalog that your body already makes. It is a three-amino-acid peptide. Glycine, histidine, lysine, that binds a copper ion. It circulates naturally in plasma, and its concentration declines substantially with age, which is what first drew research attention.
The copper is not incidental; it is central to the molecule's activity, and the blue colour of the powder comes from it. Research focuses on skin, extracellular matrix and collagen signalling. It is also widely used as a cosmetic ingredient, which makes it unusually well characterised for topical work.

Common questions
What is GHK-Cu?
A naturally occurring three-amino-acid peptide. Glycine, histidine, lysine, bound to a copper ion. It circulates in human plasma and declines with age. Listed here as a non-clinical research material.
Why is GHK-Cu blue?
The copper ion bound to the peptide gives it the blue colour. The copper is not a carrier or an additive. It is central to how the molecule works.
How much bacteriostatic water do I add to a GHK-Cu vial?
There is no single correct volume. The water volume sets the concentration: more water gives a weaker solution and a larger aliquot for the same mass. Common choices are 1 to 5 ml. Enter your vial size above to see what each volume produces for 50 mg / 100 mg.
What concentration does a GHK-Cu vial give?
It depends entirely on the solvent volume. The reference table above lists every combination of the 50 mg / 100 mg vial format and 1, 2, 3 and 5 ml of bacteriostatic water.
Does the powder change the final volume?
Not measurably at these masses. A few milligrams of lyophilized peptide occupies a negligible volume, so the bacteriostatic water you add is effectively the final volume.
Can I use normal water or saline instead?
Bacteriostatic water is the standard solvent for multi-entry vials because it contains a preservative. Sterile water and saline have no preservative, so they are single-entry solvents.
