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.

| 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 .
Hexarelin is a synthetic hexapeptide in the growth hormone releasing peptide (GHRP) class, structurally related to GHRP-6. Published research has studied its agonism at both the ghrelin / growth hormone secretagogue receptor and at CD36, a scavenger receptor implicated in cardiovascular pharmacology. It has been reported in the literature to produce strong effects on growth hormone release and has been investigated in cardiovascular research contexts. Hexarelin is not approved by the FDA for human use. Research-grade hexarelin is sold only as a laboratory reagent.
How to reconstitute Hexarelin
Research vendors typically offer hexarelin in 2 mg, 5 mg, or 10 mg lyophilized vials. Reconstitution with 2–3 mL of bacteriostatic water is commonly reported.
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
Most Hexarelin draw errors are unit errors, not arithmetic errors: confusing mg with mcg (1 mg = 1,000 mcg), or reading a U-40 syringe with U-100 math — the same printed mark holds 2.5× the volume. Two more worth avoiding: leaving the vial unlabeled, so the concentration and reconstitution date are lost, and under-diluting to the point where the draw is under about one unit and can no longer be read accurately.
Each of these is covered in full in the guides: reconstitution math from first principles, U-100 vs U-40 syringes, storage and shelf life, and how to reconstitute peptides.
