Tesamorelin Reconstitution Calculator
Tesamorelin is a stabilized GHRH analog studied for growth-hormone-axis research. It ships lyophilized and is reconstituted with bacteriostatic water. Research doses are larger than Ipamorelin, so vial-to-water ratios matter for measurement accuracy.
For laboratory research use only.
Peptide Reconstitution Calculator
Enter your vial size and bacteriostatic water volume. The calculator outputs the resulting concentration per mL and per insulin syringe unit. For procedural reference only.
Reading the result: If you have a 5mg vial reconstituted with 2mL of BAC water, your concentration is 2,500 mcg/mL. On a U-100 insulin syringe, that's 25 mcg per IU mark.

Tesamorelin concentration reference
Pre-computed concentrations for common Tesamorelin vial sizes (5 mg, 10 mg) across 1–3 mL of bacteriostatic water. All values assume a U-100 insulin syringe.
| Vial | BAC water | Concentration | Per IU (U-100) |
|---|---|---|---|
| 5 mg | 1 mL | 5,000 mcg/mL | 50 mcg |
| 5 mg | 2 mL | 2,500 mcg/mL | 25 mcg |
| 5 mg | 3 mL | 1,667 mcg/mL | 16.7 mcg |
| 10 mg | 1 mL | 10,000 mcg/mL | 100 mcg |
| 10 mg | 2 mL | 5,000 mcg/mL | 50 mcg |
| 10 mg | 3 mL | 3,333 mcg/mL | 33.3 mcg |
Tesamorelin research reference
- Dosing range: 1–2 mg per dose, daily in published research design (research range)
- Administration: Subcutaneous
- Storage: Refrigerate after reconstitution; used within 30 days in most research protocols.

How the math works
Concentration (mcg/mL) = vial mass (mg) × 1000 ÷ bacteriostatic water volume (mL). For a 5 mg Tesamorelin vial reconstituted with 2 mL, that is 2,500 mcg/mL. On a U-100 insulin syringe (100 IU marks per mL), each IU mark holds 25 mcg.
