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 |
|---|---|---|---|---|---|
| 200 mcg | 0.06 mL | 6 units | Yes | Yes | Yes |
| 300 mcg | 0.09 mL | 9 units | Yes | Yes | Yes |
| 500 mcg | 0.15 mL | 15 units | Yes | Yes | Yes |
Source Reported range, not a label dose. Reports describe 5 nights on and 2 off. The approved product, Geref, was discontinued in 2008. Vial math is arithmetic.
How to mix a 10 mg Sermorelin vial
- Wash your hands. Wipe the stopper of the Sermorelin vial and the water vial with an alcohol swab.
- Draw 3 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 3.3333 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 | 200 mcg | 300 mcg | 500 mcg |
|---|---|---|---|---|
| 1 mL | 10 mg/mL | 2 units | 3 units | 5 units |
| 2 mL | 5 mg/mL | 4 units | 6 units | 10 units |
| 3 mL | 3.3333 mg/mL | 6 units | 9 units | 15 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

How many units is 500 mcg of Sermorelin from a 10 mg vial?
With 3 mL of bacteriostatic water the vial is 3.3333 mg/mL. 500 mcg is 0.15 mL, which is 15 units on a U-100 syringe.
How much bacteriostatic water goes in a 10 mg Sermorelin vial?
3 mL is the amount used on this page. It gives 3.3333 mg/mL and puts the doses at 6, 9, 15 units. Any amount works as long as the math is redone for it.
What if I added 1 mL instead of 3 mL?
