10 mg vial
GHRP-2: a 10 mg vial
What a 10 mg vial of GHRP-2 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
10 mg + 1 mL bacteriostatic water = 10 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 10 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 |
|---|---|---|---|---|
| Diagnostic test, the approved useA single dose, once · Subcutaneous | 100 mcg | 1 unit | 100 | Clinical trial |
| Repeated dosing, as studiedTwice daily · Subcutaneous | 100 mcg – 200 mcg | 1 unit – 2 units | 100 | Clinical trial |
| Commonly described community protocolOne to three times daily · Subcutaneous | 100 mcg – 300 mcg | 1 unit – 3 units | 100 | 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.
Repeated dosing, as studied
Twice daily
One 10 mg vial holds 50–100 doses at this dose, which is 3.6–7.1 weeks of use.
| Cycle | Doses | 10 mg vials | Syringes | Bacteriostatic water |
|---|---|---|---|---|
| 8 weeks | 112 | 2–3 | 112 | 2 mL – 3 mL |
| 12 weeks | 168 | 2–4 | 168 | 2 mL – 4 mL |
| 16 weeks | 224 | 3–5 | 224 | 3 mL – 5 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 10 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 | 100 mcg draws to |
|---|---|---|
| 1 mLshown above | 10 mg/mL | 1 unit units · 0.01 mL |
| 2 mL | 5 mg/mL | 2 units units · 0.02 mL |
| 3 mL | 3.333 mg/mL | 3 units units · 0.03 mL |
| 5 mL | 2 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. Do not freeze once mixed.
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 GHRP-2 profile, each with the trial or label it came from.
