Hexarelin dosage calculator
The Hexarelin dosage calculator above converts a target dose into exact syringe units based on your vial size and how much bacteriostatic water you used to reconstitute it. Hexarelin is commonly sold in 2 mg, 5 mg, 10 mg vials. The calculator supports both U-100 and U-40 insulin syringes and flags draws that are too large for the syringe barrel or too small to measure accurately. A hexapeptide GHRP that activates both the ghrelin receptor and the CD36 scavenger receptor implicated in cardiovascular pharmacology. Enter your target dose in the calculator above to see the exact number of units to draw.
Hexarelin dosage chart
| Sample dose | Concentration | Volume to draw | Units on U-100 |
|---|---|---|---|
| 130 mcg | 2.5 mg/mL | 0.052 mL | 5.2 |
| 250 mcg | 2.5 mg/mL | 0.1 mL | 10 |
| 500 mcg | 2.5 mg/mL | 0.2 mL | 20 |
| 1000 mcg | 2.5 mg/mL | 0.4 mL | 40 |
| 2000 mcg | 2.5 mg/mL | 0.8 mL | 80 |
Hexarelin and GHRP peptides
Hexarelin is a Hexapeptide GHRP. A hexapeptide GHRP that activates both the ghrelin receptor and the CD36 scavenger receptor implicated in cardiovascular pharmacology. Other peptides in the GHRP class include Ipamorelin .
How to reconstitute Hexarelin
Reconstituting Hexarelin is the same unit-conversion process used for any lyophilized peptide:
- Draw your chosen volume of bacteriostatic water into a syringe.
- Inject the bacteriostatic water slowly down the side of the Hexarelin vial — do not shoot it directly onto the powder.
- Swirl gently until the powder fully dissolves. Do not shake.
- Store the reconstituted vial refrigerated.
- To dose, calculate your draw volume: divide your target dose by the concentration (vial mg ÷ water mL = mg/mL). The calculator above does this automatically.
For Hexarelin specifically, 2 mg, 5 mg, 10 mg vials are common. A typical reconstitution adds 2 mL of bacteriostatic water, producing a concentration of 2.5 mg/mL for the 5 mg vial size.
Hexarelin half-life and storage
Published pharmacokinetic studies report a plasma half-life of approximately 55 minutes for hexarelin.
Lyophilized hexarelin is typically stored refrigerated. Reconstituted solutions are commonly refrigerated and protected from light.
Common Hexarelin dosing mistakes
- Confusing mg and mcg. 1 mg = 1,000 mcg. Always convert to the same unit before computing the draw.
- Using a U-40 syringe with U-100 math. Same printed mark, 2.5× the physical volume. Always check the syringe label.
- Not labeling the vial. Write the reconstitution date and concentration on the vial the moment you mix it.
- Under-diluting. If your draw is less than about 1 unit, the volume is too small to read accurately — add more bacteriostatic water next time.
