100 mg vial
GHK-Cu: a 100 mg vial
What a 100 mg vial of GHK-Cu becomes once it is mixed, and what each dose reported in the sources draws to on a syringe. Every figure is arithmetic on the vial size in the heading — none of it is a recommendation, and the doses are the ones our sources describe rather than ones we picked.
Leading with
100 mg + 1 mL bacteriostatic water = 100 mg/mL
Chosen because it puts the reported doses on readable marks of a 1 mL U-100 syringe. Other volumes are perfectly valid — the dilution table further down covers them, and the concentration changes what every dose draws to.
What each reported dose draws to
At 100 mg/mL, on a 1 mL U-100 syringe. Every row names the source it came from, and a trial protocol and a community convention are not the same kind of information.
| Goal | Dose | Units | Doses in this vial | Source |
|---|---|---|---|---|
| Commonly described injected doseOnce daily · Subcutaneous | 1 mg – 2 mg | 1 unit – 2 units | 100 | Community practice |
| As delivered within a GLOW or KLOW blendOnce daily · Subcutaneous | 1.25 mg – 2 mg | 1.25 units – 2 units | 80 | Community practice |
Check every figure against the vial in front of you before drawing. Vials are filled with an overage and labels are not a guarantee. Change any of these numbers in the calculator.
How long a vial lasts
Vials round up, because most of a vial is not a thing you can buy. Only doses with a stated continuous frequency appear here — anything described as a course, a range or “as needed” has no honest weekly rate, so it is left out.
Commonly described injected dose
Once daily
One 100 mg vial holds 50–100 doses at this dose, which is 7.1–14.3 weeks of use.
| Cycle | Doses | 100 mg vials | Syringes | Bacteriostatic water |
|---|---|---|---|---|
| 8 weeks | 56 | 1–2 | 56 | 1 mL – 2 mL |
| 12 weeks | 84 | 1–2 | 84 | 1 mL – 2 mL |
| 16 weeks | 112 | 2–3 | 112 | 2 mL – 3 mL |
As delivered within a GLOW or KLOW blend
Once daily
One 100 mg vial holds 50–80 doses at this dose, which is 7.1–11.4 weeks of use.
| Cycle | Doses | 100 mg vials | Syringes | Bacteriostatic water |
|---|---|---|---|---|
| 8 weeks | 56 | 1–2 | 56 | 1 mL – 2 mL |
| 12 weeks | 84 | 2 | 84 | 2 mL |
| 16 weeks | 112 | 2–3 | 112 | 2 mL – 3 mL |
Syringes assume one per dose and no wastage. Water assumes each vial is mixed at 1 mL. Neither accounts for a dropped vial, a bent needle or a dose you decide to change, all of which happen.
If you add a different amount of water
The same 100 mg of compound, at four common volumes. More water means a larger, easier-to-measure draw of a weaker solution; less water means the opposite. The amount of compound you inject is identical in every row — only the volume carrying it changes.
| Water added | Concentration | 1 mg draws to |
|---|---|---|
| 1 mLshown above | 100 mg/mL | 1 unit units · 0.01 mL |
| 2 mL | 50 mg/mL | 2 units units · 0.02 mL |
| 3 mL | 33.333 mg/mL | 3 units units · 0.03 mL |
| 5 mL | 20 mg/mL | 5 units units · 0.05 mL |
Storage
Before mixing
Refrigerated at 2–8 °C, protected from light.
After mixing
Refrigerated at 2–8 °C. The solution is characteristically blue; that colour is expected and is not a fault.
Other vial sizes
The same compound, different arithmetic.
Arithmetic on the vial size named above and the doses our sources report. Nothing here is a recommendation, a protocol or medical advice, and no clinician has reviewed it. Some rows describe community practice, which is not evidence that a dose is safe or effective. Speak to a licensed healthcare provider before acting on any of it.
Sources for the doses above are listed in full on the GHK-Cu profile, each with the trial or label it came from.
