GHK-Cu vials are usually larger (50 mg or 100 mg) because per-dose amounts are higher than most therapeutic peptides. 5 mL of bacteriostatic water is a common reconstitution volume for these larger vials.
| Dose | 50 mg vial | 100 mg vial |
|---|---|---|
| 1 mg | 10units | 5units |
| 2 mg | 20units | 10units |
| 5 mg | 50units | 25units |

Short plasma half-life (~4 hours). Downstream gene-expression changes (collagen synthesis) persist longer.
Refrigerate after reconstitution. Copper peptides are slightly less stable than non-metal-bound peptides — use within 14-21 days for best potency.
Skin remodeling, wound healing, hair regrowth (topical or subcutaneous). Most cosmetic protocols are topical; injectable use is less common.
The math on this page is correct for the listed vial and BAC-water volume. The decision to reconstitute and inject GHK-Cu belongs to you and a clinician who knows your full history — not to a webpage.
GHK-Cu most commonly ships as 50 mg or 100 mg of lyophilized powder. The standard reconstitution is 5 mL of bacteriostatic water, which yields clean unit-mark math on a U-100 insulin syringe for the doses used in most protocols.
The standard volume is 5 mL of bacteriostatic water. You can use more (easier to draw, lower concentration) or less (more concentrated, smaller draw volume) without changing the peptide itself — only the syringe math changes. The dose table on this page is pre-calculated for 5 mL.

U-100 insulin syringes (29–31 gauge, 8–13 mm needle) are standard for subcutaneous peptide injection. Each unit on a U-100 syringe equals 0.01 mL. The dose table above shows how many units to draw for each common dose, given the vial size and standard bacteriostatic water volume.
