How Hexarelin Acetate Works

Hexarelin is a synthetic hexapeptide GH secretagogue that acts on the ghrelin receptor (GHSR-1a) to stimulate pituitary GH release. It is one of the strongest GHRPs, producing robust GH pulses even in subjects with low endogenous GH. Hexarelin also has unique cardioprotective properties mediated through CD36 (scavenger receptor class B) independent of GH release, protecting cardiomyocytes from ischemia and reducing cardiac fibrosis. Unlike GHRP-6, it produces less appetite stimulation.

Research Applications

Reconstitution Calculator

Add this much bacteriostatic water:
2.0 mL
2 mg Hexarelin Acetate + 2.0 mL BAC water = 1 mg/mL

Inject bacteriostatic water slowly along the vial wall. Gently swirl until dissolved — never shake. Store reconstituted solution at 2-8°C and use within 30 days.

Hexarelin acetate from MiPeptidos produces robust GH release in our pituitary cell cultures, stronger than GHRP-6 at equivalent doses as expected from the literature. The hexapeptide GHSR agonist tested at 98.7% purity....

Frequently Asked Questions

Hexarelin Acetate (CAS: 140703-51-1) is a research compound, with a molecular weight of 887.04 Da in the Growth Hormone / GH Secretagogues category. Hexarelin is a synthetic hexapeptide GH secretagogue that acts on the ghrelin receptor (GHSR-1a) to stimulate pituitary GH release. It is one of the strongest GHRPs, producing robust GH pulses even in subjects with low endogenous GH. Researchers commonly investigate Hexarelin Acetate for Maximum GH secretion capacity, Cardioprotection independent of GH, CD36 receptor biology. Every vial from MiPeptidos includes batch-specific analytical documentation.
Hexarelin Acetate is available in 2 sizes (2mg, 5mg), so reconstitution volume depends on which vial you have. For the 2mg size, add 1mL of bacteriostatic water; for the 5mg size, use 1-2mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted Hexarelin Acetate at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
Hexarelin is the most potent GH secretagogue in the GHRP family — it produces the highest GH spike per dose, but also the fastest desensitization (tachyphylaxis) with repeated use. Both Hexarelin and GHRP-6 are hexapeptides binding GHSR-1a, but Hexarelin has additional direct cardioprotective effects via CD36 scavenger receptors independent of GH release. At 887 Da it is slightly larger than GHRP-6 (873 Da). MiPeptidos offers both for GH pharmacology research.
Store lyophilized Hexarelin Acetate at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Hexarelin Acetate has a reported half-life of ~70 minutes, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Hexarelin Acetate order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-HXRL-2600315, tested January 5, 2026) shows 99.5% purity by HPLC, mass spectrometry confirmation at 887.04 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
