Tesamorelin Reconstitution Calculator
A synthetic GHRH analog studied in growth-hormone and metabolic research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted Tesamorelin preparation, plus the mass-to-molar conversions for its stated molecular weight.

The pre-filled example, step by step
The inputs above are the neutral reference preparation this site uses everywhere the calculator appears: a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of Tesamorelin and not an amount anyone should draw — they exist so the arithmetic is visible before you change anything.
- Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for Tesamorelin is approximately 0.4868 mM at its stated molecular weight.
- Per syringe unit. A U-100 syringe divides 1 mL into 100 units, so one unit holds 2,500 mcg ÷ 100 = 25 mcg.
- Volume for the 250 mcg target. 250 mcg ÷ 2,500 mcg/mL = 0.1 mL, or 10 units on that syringe.
- Preparations per vial. 5,000 mcg ÷ 250 mcg = 20 preparations.

Mass and molar equivalents for Tesamorelin
Derived from the molecular weight recorded on the Tesamorelin entry: Approximately 5136 g/mol — the entry states this as an approximate figure, so the equivalents below are approximate too. Concentration in molar units is what an in-vitro protocol is usually specified in.
| Quantity | Molar equivalent |
|---|---|
| 1 mg of Tesamorelin | 194.7 nmol (0.1947 µmol) |
| 1 mcg of Tesamorelin | 0.1947 nmol |
| A 1 mg/mL solution | 0.1947 mM (194.7 µM) |
Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.

Handling questions for Tesamorelin
How does tesamorelin differ from sermorelin and CJC-1295?
Sermorelin and CJC-1295 are based on the shorter GHRH(1-29) fragment, whereas tesamorelin is a stabilized analog of the full 44-amino-acid GHRH. Its N-terminal modification gives it greater stability than sermorelin while remaining a short-acting daily-dosed GHRH analog.
