Per-compound reconstitution
Each compound is calculated on its own — different vials, different concentrations, different draws. Use these references, then run your exact numbers on each compound's calculator.
Tesamorelin reference
U100 units to draw for each common Tesamorelin dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 1 mg | 1.5 mg | 2 mg |
|---|---|---|---|---|
| 2 mg | 1 mg/mL | 100 u(1 mL) | 150 u(1.5 mL) | 200 u(2 mL) |
| 5 mg | 2.5 mg/mL | 40 u(0.4 mL) | 60 u(0.6 mL) | 80 u(0.8 mL) |
| 10 mg | 5 mg/mL | 20 u(0.2 mL) | 30 u(0.3 mL) | 40 u(0.4 mL) |
Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
Ipamorelin reference
U100 units to draw for each common Ipamorelin dose, by vial size, reconstituted with 2.5 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 100 mcg | 200 mcg | 300 mcg |
|---|---|---|---|---|
| 2 mg | 0.8 mg/mL | 12.5 u(0.13 mL) | 25 u(0.25 mL) | 37.5 u(0.38 mL) |
| 5 mg | 2 mg/mL | 5 u(0.05 mL) | 10 u(0.1 mL) | 15 u(0.15 mL) |
Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
Running tesamorelin with ipamorelin
Tesamorelin and ipamorelin act on different parts of the GH axis, so they are often dosed together. Each vial reconstitutes to its own concentration — tesamorelin doses are in milligrams, ipamorelin in micrograms — so the draws look very different. Calculate each on its own page.
- Tesamorelin: mg doses; ipamorelin: mcg doses
- Different concentrations — never share a draw figure
- Commonly dosed at the same time
Why the draws differ so much
Because tesamorelin is dosed in milligrams and ipamorelin in micrograms, their syringe units differ by an order of magnitude even at the same vial size and water volume. The per-compound reference tables above show each independently so you do not mix them up.
- An order-of-magnitude difference in dose scale
- Calculate and draw each separately
- Track two reconstitution dates and doses-remaining counts
