Hexarelin 5 mg

Hexarelin 5 mg contains examorelin, a potent growth hormone secretagogue peptide. In research settings it is used to stimulate GH release via GHS-R1a receptor activation. In non-medical bodybuilding contexts, hexarelin is commonly referenced for its GH-stimulating properties, though such use falls outside approved indications.

Community protocols commonly reference hexarelin being injected 1–2 times daily at doses of 100–200 mcg per injection. Due to rapid receptor desensitization, cycle lengths are typically limited to 4–6 weeks followed by a break. Doses are typically timed on an empty stomach to maximize the GH response.

Hexarelin does not suppress endogenous testosterone production because it acts on the GHS-R1a receptor rather than the hypothalamic-pituitary-gonadal axis. Post-cycle therapy is therefore generally not considered necessary after hexarelin use alone. However, a 4-week break between cycles is commonly referenced to allow receptor resensitization.

Examorelin stimulates growth hormone release by activating the GHS-R1a receptor in the pituitary and hypothalamus. It also binds to the CD36 receptor in cardiac tissue, mediating cardioprotective effects independent of GH. Hexarelin additionally causes significant elevations in prolactin, ACTH, and cortisol.

The GH pulse from a single hexarelin injection typically peaks within 15–30 minutes and returns to baseline within a few hours. However, GH response attenuation begins within 2–4 weeks of continuous use, which is why cycle lengths are typically limited. After a 4-week break, receptor sensitivity is generally restored.

There is no single GH secretagogue that is universally best. Hexarelin produces the strongest GH pulse but also the most pronounced cortisol and prolactin elevation and the fastest desensitization. Ipamorelin is more selective with minimal side effects and no desensitization, making it better for long-term use. The appropriate choice depends on individual goals and cycle strategy.

Hexarelin produces 2–3 times the GH peak of GHRP-2 but desensitizes within weeks and elevates cortisol and prolactin more significantly. GHRP-2 produces strong GH stimulation with moderate cortisol and prolactin elevation and slower desensitization, making it a better choice for 10–12 week cycles.

Hexarelin produces the strongest GH pulse but with significant cortisol and prolactin elevation and rapid desensitization. Ipamorelin produces cleaner, more selective GH release with virtually no side effects and no desensitization, making it the better choice for long-term use. The proven strategy is to use hexarelin for a 4–6 week blast, then switch to ipamorelin for months of maintenance.

100 mcg is commonly referenced as a conservative starting dose for hexarelin, producing roughly 70–90% of the maximal GH response while keeping cortisol and prolactin moderate. Doses of 100–200 mcg per injection are typical in community protocols. The 5 mg vial contains 5,000 mcg total, providing 25–50 doses at these levels.

Hexarelin 5 mg is labeled at 5 mg of examorelin per vial. It is supplied as a lyophilized powder in a 2 mL vial, requiring reconstitution before use.

Yes. A published laboratory report dated September 12, 2025 measured Hexarelin 5 mg at 5.34 mg, equivalent to 106.8% of its 5 mg label claim. The batch number for this report is #HEXAHD6.

The complete report can be viewed in the Lab Reports tab. Laboratory results apply to the tested sample represented by the individual report and should not be interpreted as a measurement of every vial.

Lyophilized hexarelin is typically reconstituted with a suitable solvent such as Bacteriostatic Water or sterile water. The volume of solvent added determines the concentration of the resulting solution. Proper sterile technique should be used during reconstitution.
