5 mg vial
Thymosin alpha-1: a 5 mg vial
What a 5 mg vial of Thymosin alpha-1 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
5 mg + 2 mL bacteriostatic water = 2.5 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 2.5 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 |
|---|---|---|---|---|
| Approved regimen for hepatitis BTwice weekly for six months · Subcutaneous | 1.6 mg | 64 units | 3 | Clinical trial |
| Commonly described for general useTwo or three times weekly · Subcutaneous | 450 mcg – 1.6 mg | 18 units – 64 units | 11 | 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.
If you add a different amount of water
The same 5 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 | 1.6 mg draws to |
|---|---|---|
| 1 mL | 5 mg/mL | 32 units units · 0.32 mL |
| 2 mLshown above | 2.5 mg/mL | 64 units units · 0.64 mL |
| 3 mL | 1.667 mg/mL | 96 units units · 0.96 mL |
| 5 mL | 1 mg/mL | Exceeds a 1 mL barrel |
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 Thymosin alpha-1 profile, each with the trial or label it came from.
