Follistatin-344: a 1 mg vial
What a 1 mg vial of Follistatin-344 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
1 mg + 1 mL bacteriostatic water = 1 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 1 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 community protocolDaily for a course of 10 to 30 days · Subcutaneous | 100 mcg – 300 mcg | 10 units – 30 units | 10 | 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 1 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 | 1 mg/mL | 10 units units · 0.1 mL |
| 2 mL | 0.5 mg/mL | 20 units units · 0.2 mL |
| 3 mL | 0.333 mg/mL | 30 units units · 0.3 mL |
| 5 mL | 0.2 mg/mL | 50 units units · 0.5 mL |
Storage
Before mixing
Refrigerated at 2–8 °C, protected from light.
After mixing
Refrigerated at 2–8 °C, and used quickly. A large glycoprotein is far less stable in solution than a short peptide, and it will not look any different once it has lost activity.
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.
