Hexarelin

Overview

What is Hexarelin?

Hexarelin is a synthetic hexapeptide growth hormone secretagogue that produces the strongest pulse in its class. It also desensitises fastest, with the response falling within two to four weeks of continuous use, so protocols are cycled rather than run continuously.

What the research reports

Reported benefits of Hexarelin

Outcomes described across the published Hexarelin literature and ongoing study. Read each as research context rather than a promised personal result.

1. 01

   Strongest GH pulse in class

   Produces a larger growth hormone response than other peptides in the ghrelin receptor family, which is its defining pharmacological characteristic within the class.

2. 02

   Pituitary reserve testing

   A 1999 cohort found the hexarelin test reliable for screening growth hormone deficiency, though unreliable for ACTH and cortisol reserve. Reported in research settings.

3. 03

   Cushing's differentiation

   A 2000 trial reported the hexarelin test effectively separated Cushing's disease from alcohol induced pseudo-Cushing's syndrome. Reported in research settings.

4. 04

   Cardiac research interest

   A separate research line explores cardioprotective effects through CD36 signalling that appear independent of growth hormone release. Reported in research settings.

5. 05

   Metabolic pathway research

   Work describes CD36 and PPAR gamma activation linked to insulin resistance and lipid handling in metabolic disorder models. Reported in research settings.

Dosage and protocol

How Hexarelin is typically studied

Protocols use 100 to 200 mcg two or three times daily, cycled 2 to 4 weeks on and 4 weeks off because of rapid desensitisation. Figures describe study protocols, not a personal regimen.

Route

Subcutaneous injection

Example range

100-200 mcg

Frequency

Two to three times daily

Timing

Empty stomach, 30 min before meals. Cycling is required by design.

Clinical evidence

Clinical evidence for Hexarelin

The published Hexarelin record, labeled by strength so you can see what is settled and what is still emerging.

Interactions

How Hexarelin pairs with other peptides

GHRP-2 peptide

Both act on the ghrelin receptor, so combining duplicates one target and compounds cortisol effects.

CJC-1295 blend

Synergistic on first dosing, though published work shows the synergy fades with repeated administration.

Ipamorelin

Same receptor family with a far lower side effect profile, so combining offers little practical gain.

MK-677 oral use

Stacking secretagogues raises IGF-1 and insulin resistance risk while desensitisation still applies.
