The arithmetic, step by step
Every reconstitution conversion comes back to one number: the concentration of peptide per millilitre of solution. With 5 mg of Tesamorelin dissolved in 2 mL of bacteriostatic water, the concentration is 5 ÷ 2 = 2.5 mg/mL. Once that figure is fixed, every other conversion follows from it.
A U-100 insulin syringe is graduated to 100 units per millilitre. That means one unit on the barrel corresponds to 1 ÷ 100 = 0.01 mL of solution, which carries 0.025 mg of Tesamorelin. Multiplying through by the number of units drawn gives the dose in milligrams; dividing a target dose by that per-unit mass gives the units to draw. The lookup table above is just those two operations applied at common round-number inputs.
The micro-to-milli conversion sits one step above this layer. One milligram is 1,000 micrograms, so a 1 mg reference dose is the same as 1000 mcg of Tesamorelin. The mass does not change with the unit label — the calculator and the lookup table treat the two interchangeably.
These figures hold only at the listed vial-to-water ratio. Tesamorelin is also shipped in vial sizes of 1 mg, 2 mg, 5 mg, 10 mg in research-vendor presentations, and changing the vial size — or the volume of BAC water used to reconstitute it — produces a different concentration and therefore a different lookup table. The calculator handles those overrides directly.
Concentration at other common vial sizes
Tesamorelin ships in several vial sizes. At a fixed 2 mL of BAC water, the concentration scales linearly with the vial — and so does every value in the lookup table.
| Vial size | Concentration | 1 mg draws |
|---|---|---|
| 1 mg | 0.5 mg/mL | 200 units (2 mL) |
| 2 mg | 1 mg/mL | 100 units (1 mL) |
| 5 mg | 2.5 mg/mL | 40 units (0.4 mL) |
| 10 mg | 5 mg/mL | 20 units (0.2 mL) |

Frequently asked questions
- How do you convert Tesamorelin mcg to units?
- On a 5 mg vial reconstituted with 2 mL of bacteriostatic water, the concentration is 2.5 mg per mL. From there, the conversion is a single division (or multiplication) — see the lookup table above for the worked values.
- Does the conversion change with a different vial size?
- Yes. The same peptide reconstituted at a different vial-to-water ratio gives a different concentration, and every value in the lookup table shifts accordingly. Use the calculator linked on this page to override the defaults.
- What syringe should I assume?
- The lookup table on this page uses a U-100 insulin syringe (100 units per mL). On a U-40 syringe the units would scale proportionally — the underlying mass is the same.
- Why does the table only go up to certain values?
- The table is bounded by the vial's total peptide content and the BAC water volume in the vial. Values above those thresholds are not physically possible to draw from a single vial at the listed concentration.
- Is this conversion specific to Tesamorelin?
- The arithmetic is general, but the input values (vial size, BAC water volume, default syringe) are Tesamorelin-specific reference defaults drawn from the per-peptide reference page. Different peptides ship in different vial sizes, so the lookup table changes.
