Each row is one dose, the volume to draw and where that sits on a U-100 insulin syringe. The last three columns show which syringe sizes can hold it in one draw.
| Dose | Volume | Syringe units | 0.3 mL syringe | 0.5 mL syringe | 1 mL syringe |
|---|---|---|---|---|---|
| 2 mg | 1.00 mL | 100 units | No | No | Yes |
| 2.5 mg | More than this vial holds | ||||
Source Reported range, not a label dose. Reports describe twice a week for 4 to 6 weeks, then once a week or less. Human trials used thymosin beta-4, not TB-500. Vial math is arithmetic.
How to mix a 2 mg TB-500 vial
- Wash your hands. Wipe the stopper of the TB-500 vial and the water vial with an alcohol swab.
- Draw 1 mL of bacteriostatic water into a syringe.
- Push the needle through the stopper of the peptide vial and let the water run slowly down the glass, not straight onto the powder.
- Swirl the vial gently until the powder is gone. Do not shake it.
- Write the date and 2 mg/mL on the vial, then put it in the fridge.
If you add a different amount of water
More water makes each dose a bigger, easier draw. Less water makes it smaller. The milligrams in the vial do not change.
| Water added | Concentration | 2 mg |
|---|---|---|
| 1 mL | 2 mg/mL | 100 units |
| 2 mL | 1 mg/mL | 200 units |
| 3 mL | 0.6667 mg/mL | 300 units |
The marked row is the amount used in the chart above. Red cells are draws under 5 units, which are hard to read, or over 100 units, which one 1 mL syringe cannot hold.
How many doses are in the vial
| Dose | Whole doses in a 2 mg vial |
|---|---|
| 2 mg | 1 dose |
How long the vial lasts depends on how often it is used. The reported frequency for TB-500 is: twice weekly, then weekly.
TB-500 2 mg vial questions
How many units is 2 mg of TB-500 from a 2 mg vial?
With 1 mL of bacteriostatic water the vial is 2 mg/mL. 2 mg is 1.00 mL, which is 100 units on a U-100 syringe.
How much bacteriostatic water goes in a 2 mg TB-500 vial?
1 mL is the amount used on this page. It gives 2 mg/mL and puts the doses at 100 units. Any amount works as long as the math is redone for it.
What if I added 2 mL instead of 1 mL?
The vial would be 1 mg/mL instead of 2 mg/mL, so 2 mg would be 200 units instead of 100. The dose in the syringe is the same; only the volume changes.
How many doses are in a 2 mg TB-500 vial?
Whole doses in one vial: 1 at 2 mg.
