Sermorelin Dosage Calculator: Reconstitution and Units
To calculate Sermorelin dosage, divide your target dose (mg) by the vial concentration. For a 3 mg vial with 3 mL BAC water: concentration is 1 mg/mL. A 100 mcg (0.1 mg) dose equals 0.1 mL (10 U-100 units). A 300 mcg (0.3 mg) dose equals 0.3 mL (30 U-100 units).

| Vial (mg) | BAC water (mL) | Concentration | Dose (mg) | Draw (mL) | U-100 units |
|---|---|---|---|---|---|
| 3 mg | 3 mL | 1 mg/mL | 0.1 mg | 0.1 mL | 10 units |
| 3 mg | 3 mL | 1 mg/mL | 0.2 mg | 0.2 mL | 20 units |
| 3 mg | 3 mL | 1 mg/mL | 0.3 mg | 0.3 mL | 30 units |
| 5 mg | 2 mL | 2.5 mg/mL | 0.1 mg | 0.04 mL | 4 units |
| 5 mg | 2 mL | 2.5 mg/mL | 0.3 mg | 0.12 mL | 12 units |
How to Calculate Sermorelin Dosage
Three steps convert any vial and BAC water combination into the exact volume to draw on a U-100 insulin syringe.
Step 1 — Calculate concentration (mg/mL)
Divide the total peptide in the vial (mg) by the volume of BAC water you added (mL). For example: a 5 mg Sermorelin vial reconstituted with 2 mL BAC water gives 5 ÷ 2 = 2.5 mg/mL.Step 2 — Calculate draw volume (mL)
Divide your target dose (mg) by the concentration (mg/mL). For a 0.5 mg dose at 2.5 mg/mL: 0.5 ÷ 2.5 = 0.2 mL. This is the exact volume to draw into the syringe.Step 3 — Convert to U-100 syringe units
Multiply the draw volume (mL) by 100. For 0.2 mL: 0.2 × 100 = 20 U-100 units. Read this number on the unit markings of a standard insulin syringe.
Dosage Formula
Concentration formula
Concentration (mg/mL) = Vial mg ÷ BAC water mLDraw volume formula
Draw volume (mL) = Dose (mg) ÷ Concentration (mg/mL)U-100 syringe units
U-100 units = Draw volume (mL) × 100These three formulas apply to any Sermorelin vial, regardless of size. U-100 is the standard insulin-syringe scale: 100 units = 1 mL.

Example Sermorelin Calculations
Step-by-step worked examples using common vial sizes. Results are for illustrating the math only.
100 mcg (0.1 mg) dose from 3 mg / 3 mL vial
- Vial: 3 mg | BAC water: 3 mL | Target dose: 0.1 mg
- Concentration: 3 ÷ 3 = 1 mg/mL
- Draw volume: 0.1 ÷ 1 = 0.1 mL
- U-100 units: 0.1 × 100 = 10 units
300 mcg (0.3 mg) dose from 3 mg / 3 mL vial
- Vial: 3 mg | BAC water: 3 mL | Target dose: 0.3 mg
- Concentration: 3 ÷ 3 = 1 mg/mL
- Draw volume: 0.3 ÷ 1 = 0.3 mL
- U-100 units: 0.3 × 100 = 30 units
Sermorelin Reconstitution Guide
Sermorelin is a GHRH (growth hormone-releasing hormone) analog typically supplied as a lyophilised powder in 3 mg or 5 mg vials. Doses are often measured in mcg — use the mcg-to-mg conversion (÷ 1000) before entering into the calculator.
- Swab both vial stoppers with alcohol swabs and allow to dry.
- Draw 3 mL BAC water for a 3 mg vial to achieve 1 mg/mL (1000 mcg/mL).
- Inject BAC water slowly along the glass wall of the peptide vial.
- Gently swirl until the powder dissolves. Do not shake.
- Store at 2–8 °C and use within 4–6 weeks.
Frequently Asked Questions
How do I convert Sermorelin mcg doses to mL?
First divide the mcg dose by 1000 to get mg. Then use: draw volume (mL) = dose (mg) ÷ concentration (mg/mL). For 300 mcg = 0.3 mg at 1 mg/mL: draw 0.3 mL = 30 U-100 units.
What is the standard Sermorelin reconstitution?
A 3 mg vial + 3 mL BAC water = 1 mg/mL (1000 mcg/mL). At this concentration every 0.1 mL = 100 mcg, making fine-tuning straightforward on a U-100 insulin syringe.
What are U-100 syringe units?
U-100 is the standard scale for insulin syringes. 100 units = 1.0 mL. That means 10 units = 0.1 mL, 50 units = 0.5 mL. Multiply any draw volume in mL by 100 to get the U-100 units reading.
Do I need to recalculate if I change the amount of BAC water?
Yes. Changing BAC water volume changes the concentration (mg/mL), which changes the draw volume for the same mg dose. Always recalculate using: concentration = vial mg ÷ BAC water mL, then draw volume = dose mg ÷ concentration.
How do I convert mcg to mg for the calculator?
Divide mcg by 1000 to get mg. For example: 250 mcg = 0.25 mg, 500 mcg = 0.5 mg, 1000 mcg = 1 mg. Enter the mg value in the calculator.
What is Sermorelin studied for?
Sermorelin is a GHRH analog studied for its role in stimulating pituitary GH release. It is a research compound and not approved for general therapeutic use without a prescription.
