GHRP-6 Dosage Calculator: Reconstitution and Units
To calculate a GHRP-6 dose, divide the vial mg by BAC water mL to get concentration (mg/mL), divide your target dose in mg by concentration to get draw volume (mL), then multiply by 100 for U-100 units. GHRP-6 doses are typically discussed in the 100–300 mcg range.

| Vial (mg) | BAC water (mL) | Concentration | Dose (mg) | Draw (mL) | U-100 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 | 0.2 mg | 0.08 mL | 8 units |
| 5 mg | 2 mL | 2.5 mg/mL | 0.3 mg | 0.12 mL | 12 units |
| 10 mg | 5 mL | 2 mg/mL | 0.2 mg | 0.1 mL | 10 units |
How to Calculate GHRP-6 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 GHRP-6 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 GHRP-6 vial, regardless of size. U-100 is the standard insulin-syringe scale: 100 units = 1 mL.

Example GHRP-6 Calculations
Step-by-step worked examples using common vial sizes. Results are for illustrating the math only.
5 mg vial + 2 mL BAC + 100 mcg (0.1 mg) dose
- Vial: 5 mg | BAC water: 2 mL | Target dose: 0.1 mg
- Concentration: 5 ÷ 2 = 2.5 mg/mL
- Draw volume: 0.1 ÷ 2.5 = 0.04 mL
- U-100 units: 0.04 × 100 = 4 units
10 mg vial + 5 mL BAC + 200 mcg (0.2 mg) dose
- Vial: 10 mg | BAC water: 5 mL | Target dose: 0.2 mg
- Concentration: 10 ÷ 5 = 2 mg/mL
- Draw volume: 0.2 ÷ 2 = 0.1 mL
- U-100 units: 0.1 × 100 = 10 units
GHRP-6 Reconstitution Guide
GHRP-6 is a lyophilized hexapeptide typically supplied in 5 mg or 10 mg vials.
- Add BAC water slowly down the side of the vial. Swirl gently — do not shake.
- Common setup: 5 mg vial + 2 mL BAC = 2.5 mg/mL. Each 0.1 mg (100 mcg) dose = 0.04 mL = 4 units.
- Refrigerate at 2–8 °C once reconstituted. Use within 4 weeks.
Frequently Asked Questions
What is GHRP-6?
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that stimulates growth hormone secretion via the ghrelin receptor. It is a research compound.
How does GHRP-6 differ from GHRP-2?
Both are GH secretagogues but GHRP-6 is associated with stronger appetite stimulation in research models while GHRP-2 is considered more selective with less hunger response.
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.
