Quick math example
A 5 mg vial mixed with 2 mL gives 2,500 mcg/mL. A 300 mcg dose is 0.12 mL, which equals 12 units on a U-100 syringe.
Reconstitution reference
U100 units to draw for each common Sermorelin 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 | 200 mcg | 300 mcg | 500 mcg |
|---|---|---|---|---|
| 2 mg | 1 mg/mL | 20 u(0.2 mL) | 30 u(0.3 mL) | 50 u(0.5 mL) |
| 5 mg | 2.5 mg/mL | 8 u(0.08 mL) | 12 u(0.12 mL) | 20 u(0.2 mL) |
| 10 mg | 5 mg/mL | 4 u(0.04 mL) | 6 u(0.06 mL) | 10 u(0.1 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.
How the sermorelin calculation works
Sermorelin vials are labelled in milligrams while doses are usually discussed in micrograms. The calculator converts the vial total to mcg, divides by your BAC water volume to find concentration, then divides your target dose by that concentration.
Doses are small, so a U-100 insulin syringe makes the draw easier to read than a larger barrel.
- 5 mg vial = 5,000 mcg total
- 5,000 mcg / 2 mL = 2,500 mcg per mL
- 300 mcg target = 0.12 mL draw
Sermorelin 5 mg vial with 2 mL example
A 5 mg sermorelin vial mixed with 2 mL gives 2.5 mg/mL, or 2,500 mcg/mL.
A 300 mcg dose is 0.12 mL, which equals 12 units on a U-100 syringe; a 200 mcg dose is 0.08 mL, or 8 units. Reconstituting in 1 mL instead doubles the concentration and halves each draw.
- 5 mg / 2 mL = 2.5 mg/mL → 300 mcg = 0.12 mL = 12 units
- 5 mg / 2 mL = 2.5 mg/mL → 200 mcg = 0.08 mL = 8 units
- 5 mg / 1 mL = 5 mg/mL → 300 mcg = 0.06 mL = 6 units
Sermorelin vs other GH-releasing peptides
Sermorelin is a GHRH analogue, like tesamorelin, and is often discussed alongside the GHRP-class secretagogues such as ipamorelin. The reconstitution math is identical across all of them — only the vial sizes and typical doses differ — so if you run more than one, calculate each on its own page.
- Same concentration math as tesamorelin and ipamorelin
- Calculate each compound separately if you run several
- A consistent water volume keeps your unit counts comparable
