Example Hexarelin Titration Schedule
| Item | Details |
|---|---|
| Dose | 100–200 mcg per injection |
| Frequency | 2–3× per day, fasted |
| Cycle | 4–6 weeks MAX, then 4–6 off |
| Unique | CD36 cardiac binding (GH-independent) |
Fastest desensitizer of the GHRP class: continuous use cuts the GH response ~50% by week 4, recovering after 4 weeks off — hence the shortest cycles. Highest acute GH pulse of any GHRP in human head-to-head studies.

Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.
- Use clean syringe-unit math before measuring.
Common Mistakes
- Confusing milligrams with milliliters.
- Choosing an option with awkward decimal units.
- Using too little liquid for very small measurements.
- Shaking the vial aggressively.
Hexarelin Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions
Hexarelin is a synthetic hexapeptide growth hormone secretagogue — essentially a more powerful relative of GHRP-6 — that activates the ghrelin receptor (GHS-R1a) to trigger a large, fast pulse of your own growth hormone. It is not a steroid, and not identical to GHRP-6 even though it's built on the same backbone; it's a research peptide, not an approved drug. Among the common GHRPs, hexarelin produces the strongest acute GH release per dose.
In research and community reports, hexarelin is dosed in micrograms — commonly around 100–200 mcg per injection, subcutaneously, one to a few times a day on an empty stomach, with GH peaking roughly 30 minutes later. Crucially, it is run in cycles (often 4–8 weeks on, then a break) rather than continuously, because its effect fades quickly with daily use. These are reference figures from the literature, not an approved regimen, and suitability is a clinical decision.
Add bacteriostatic water slowly down the side of the dry vial and swirl — never shake. For example, a 2 mg vial + 1 mL of water gives 2 mg/mL (2,000 mcg/mL); a 100 mcg dose is then 0.05 mL, which is 5 units on a U-100 insulin syringe. Use the calculator above to match your real vial size (2 mg and 5 mg are common) and target dose. Doses are in micrograms, so measure carefully — small volume errors are a large share of the dose.
Hexarelin's signature problem is rapid desensitization (tachyphylaxis): with continued daily use the ghrelin receptor downregulates and the GH response can fall by roughly half or more within a few weeks. This is exactly why it's cycled with off-periods, or rotated with a gentler secretagogue like ipamorelin while the receptor recovers — running it nonstop mostly buys side effects, not more GH. It's the one trait that most separates hexarelin from the other GHRPs: the highest peak, but the least durable.
Despite a reputation as the "strongest" GHRP, the research picture is a trade-off: hexarelin raises cortisol and prolactin more than any common GHRP and desensitizes fastest, so raw potency doesn't translate into better sustained results. It is not a steroid and nothing like trenbolone — it's a peptide that signals your pituitary, not an androgen. It does have one genuinely unique feature: it binds the cardiac CD36 receptor and has shown cardioprotective effects in animal studies, though that isn't clinically proven. It's not FDA-approved and is banned by WADA; store the dry vial cold and dark, and once reconstituted keep it refrigerated and use within a few weeks.
Practical takeaway: If your goal involves weight management, metabolic health, recovery, physical performance, cognitive function, appearance, or general well-being, discuss it with a licensed healthcare professional. They can help you evaluate approved, evidence-based options rather than relying on an unapproved or investigational compound. This calculator is intended only for transparent research-reference calculations and does not determine an appropriate amount, recommend use, or replace professional medical guidance.
