Hexarelin FAQ: Reconstitution, Storage, Purity & Sourcing
3 min read•Published 2025-09-15•Quality Peptide USA Research
Hexarelin is a synthetic hexapeptide ghrelin-receptor agonist closely related to GHRP-6. It is widely studied in cardiac and somatotropic research due to its high potency at the GHS-R1a receptor and additional reported activity at the CD36 receptor in tissue models.. This guide covers faq for researchers for Hexarelin — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.
Is Hexarelin research-grade?
Yes. Every batch of Hexarelin sold by Quality Peptide USA is released to a ≥ 99% HPLC purity specification, with mass-spec identity confirmation and LAL endotoxin testing on every lot. The certificate of analysis is published on the product page.
How should Hexarelin be reconstituted?
Reconstitute Hexarelin with bacteriostatic water (0.9% benzyl alcohol). Inject the water down the inside wall of the vial — do not inject directly onto the lyophilized cake. Swirl gently until fully dissolved. Refrigerate at 2–8°C after reconstitution.
What is the reported half-life?
≈ 55 minutes (research models) Half-life figures from in-vitro models are not directly transferable to ex-vivo or in-vivo systems.
Where is Hexarelin synthesized?
Hexarelin is synthesized in the United States and ships from a US facility. No overseas drop-shipping, no customs delays, full domestic cold chain.
What testing is performed on each batch?
RP-HPLC purity (≥ 99% spec), ESI / MALDI-TOF mass spectrometry, Karl Fischer water content, LAL endotoxin screen, and bioburden. All results are published on the per-batch certificate of analysis.
Can Hexarelin be stacked with other peptides?
Many research protocols pair Hexarelin with complementary peptides — the Glow stack for dermal models, the Wolverine stack for tissue repair, or GHRH/GHRP secretagogue blends for somatotropic studies. Review the published literature for your specific endpoint before designing a stacked protocol.
