Hexarelin Storage & Stability: Cold Chain, Half-Life & Shelf Life
3 min read•Published 2025-05-11•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 storage & stability for Hexarelin — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.
Lyophilized Shelf Life
Sealed lyophilized Hexarelin stored at 2–8°C maintains potency through the expiration date listed on the certificate of analysis (typically 24–36 months from manufacture). Short transit exposure to room temperature during shipping does not meaningfully degrade lyophilized peptide — the vacuum-sealed solid form is highly stable. Once received, refrigerate promptly for long-term storage.
Reconstituted Solution Stability
Lyophilized: 2–8°C. Reconstituted: refrigerate, use within 30 days. Benzyl alcohol in bacteriostatic water provides bacteriostatic protection but does not extend chemical stability indefinitely. Investigators running multi-week protocols should plan their aliquoting strategy in advance.
Reported Research Half-Life
Reported in-vitro / preclinical half-life for Hexarelin: ≈ 55 minutes (research models) Half-life depends on study system — plasma, tissue culture media, and intact-animal models all yield different effective windows.
Cold-Chain Shipping by Quality Peptide USA
Every order of Hexarelin ships with insulated cold packaging for transit, dispatched from US facilities on the same day for orders placed before 2 PM EST. Tracking is provided on every shipment so research teams can plan receiving and cold-room storage.
