How to Store Hexarelin Long Term: Storage Method Comparison
Lyophilized at −20°C (sealed vial) 24–36 months Minimal if humidity <40% and no temperature excursions above −15°C Long-term bulk storage before protocol initiation Gold standard for preservation. Achievable in any lab with proper freezer monitoring Lyophilize

- Lyophilized at −20°C (sealed vial)
- 24–36 months
- Minimal if humidity <40% and no temperature excursions above −15°C
- Long-term bulk storage before protocol initiation
- Gold standard for preservation. Achievable in any lab with proper freezer monitoring
- Lyophilized at 4°C (sealed vial)
- 6–12 months
- Moderate. Oxidation at Trp residues accelerates
- Emergency short-term storage if −20°C unavailable
- Acceptable for <6 months but requires monthly visual inspection for discoloration
- Reconstituted at 2–8°C (multi-dose vial)
- 28 days maximum
- High. Deamidation and aggregation both proceed measurably
- Active research protocols with daily/weekly dosing
- Standard approach but requires strict adherence to 28-day discard rule
- Reconstituted and frozen at −20°C (aliquots)
- 90–120 days
- Moderate if single thaw per aliquot; severe if refrozen
- Protocols requiring infrequent dosing over months
- Best practice for extended protocols. Aliquoting prevents freeze-thaw degradation
- Room temperature (any form)
- <48 hours
- Severe and irreversible. Complete loss of potency within 72 hours
- Transport only with validated cold packs
- Unacceptable for storage. Suitable only for <6 hour transport windows
- Every storage decision is a trade-off between convenience and molecular stability. Researchers frequently choose multi-dose vial storage at 4°C because it's simpler. One vial, easy access. That choice works for 28 days. Beyond that, you're dosing with degraded peptide.
