Dose on a U-100 syringe (100–200 mcg)
| Vial | BAC water | Draw |
|---|---|---|
| 5 mg | 2.5 mL | 5.0–10 units |
| 5 mg | 3 mL | 6.0–12 units |
| 10 mg | 2.5 mL | 2.5–5.0 units |
| 10 mg | 3 mL | 3.0–6.0 units |
On a U-100 syringe, 100 units = 1 mL, and the syringe holds 100 units total. Most people keep a single subcutaneous injection under about 50 units — bigger volumes are usually mixed stronger (less water) or split into two shots. Only mixes that fit in one syringe are shown. Always double-check with the reconstitution calculator.
What it does
Hexarelin is a synthetic hexapeptide growth hormone secretagogue and one of the most potent GHRPs. It is researched for growth hormone release, muscle recovery, and cardioprotective effects, though it is known for relatively fast receptor desensitization.
Mechanism
Hexarelin binds the ghrelin receptor (GHS-R1a) in the pituitary and hypothalamus, strongly stimulating pulsatile growth hormone release. It also acts on CD36 receptors in cardiac tissue, which is the basis for its studied cardioprotective effects.
Storage — lyophilisedwhat's this?
Store lyophilized at -20C for long-term storage.
Storage — reconstitutedwhat's this?
Refrigerate at 2-8C after reconstitution and use within 30 days.
Reconstitution noteswhat's this?
Reconstitute with bacteriostatic water. Because desensitization develops with continuous use, research protocols typically cycle Hexarelin or limit it to a few doses per day.
Commonly stacked with
- CJC-1295 (no DAC)
- Ipamorelin
Commonly reported side effects
- Increased hunger
- Water retention
- Elevated cortisol and prolactin at higher doses
- Tingling or numbness in extremities
Contraindications noted
- Pregnancy or breastfeeding
- Active cancer (GH stimulation)
- Uncontrolled diabetes
Research notes
Hexarelin raises cortisol and prolactin more than Ipamorelin, which is why many researchers prefer Ipamorelin for long-term use. Cycling helps limit receptor desensitization.
