2 mg vial
Thymosin Beta-4: a 2 mg vial
What a 2 mg vial of Thymosin Beta-4 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
2 mg + 1 mL bacteriostatic water = 2 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 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 |
|---|---|---|---|---|
| Ophthalmic trial protocolApplied as an eye drop, twice daily · Topical | 100 mcg | 5 units | 20 | Clinical trial |
| Commonly described community protocolTwice weekly during a loading phase, then weekly · Subcutaneous | 2 mg – 5 mg | from 100 unitstop of the range needs a second vial | 1 | 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.
Ophthalmic trial protocol
Applied as an eye drop, twice daily
One 2 mg vial holds 20 doses at this dose, which is 1.4 weeks of use.
| Cycle | Doses | 2 mg vials | Syringes | Bacteriostatic water |
|---|---|---|---|---|
| 8 weeks | 112 | 6 | 112 | 6 mL |
| 12 weeks | 168 | 9 | 168 | 9 mL |
| 16 weeks | 224 | 12 | 224 | 12 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 2 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 | 2 mg/mL | 5 units units · 0.05 mL |
| 2 mL | 1 mg/mL | 10 units units · 0.1 mL |
| 3 mL | 0.667 mg/mL | 15 units units · 0.15 mL |
| 5 mL | 0.4 mg/mL | 25 units units · 0.25 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 Thymosin Beta-4 profile, each with the trial or label it came from.
