Overview
Proper storage and reconstitution of GLP-3 (Retatrutide) is critical for maintaining peptide integrity and ensuring reproducible research outcomes. This guide outlines laboratory best practices for handling lyophilized GLP-3, consistent with standard research peptide protocols.
Storage of Lyophilized GLP-3
GLP-3 is supplied in lyophilized (freeze-dried) powder form. Proper storage conditions are essential to preserve structural integrity:
- Long-term storage: -20°C in a dry, dark environment
- Short-term storage (under 4 weeks): 2-8°C refrigeration is acceptable
- Protect from: Light, moisture, and repeated temperature fluctuations
- Shelf life: Lyophilized peptides stored at -20°C remain stable for 24+ months when properly sealed
- Do not: Store at room temperature for extended periods or expose to direct sunlight
Reconstitution Protocol
GLP-3 requires reconstitution with a suitable laboratory-grade diluent prior to research use. Standard protocol:
- Recommended diluent: Bacteriostatic water (0.9% benzyl alcohol) for multi-use vials, or sterile saline for single-use applications
- Reconstitution method: Add diluent slowly along the interior wall of the vial — do not inject directly onto the lyophilized powder
- Mixing: Gently swirl to dissolve — do not shake or vortex, as mechanical agitation can denature the peptide structure
- Reconstituted storage: 2-8°C, use within 28-30 days
- Freeze-thaw cycles: Avoid repeated freezing of reconstituted solution — aliquot into single-use volumes before freezing if extended storage is needed
Laboratory Handling Precautions
- Handle in a sterile environment — laminar flow hood or biosafety cabinet recommended
- Use sterile, single-use syringes and needles for all transfers
- Label vials with date of reconstitution and lot number for traceability
- Document all handling procedures per institutional research protocols
- Dispose of peptide materials according to your institution’s biohazard waste procedures
Quality Verification
All GLP-3 (Retatrutide) supplied by Peppy University is:
- Third-party tested via HPLC for purity verification (99%+)
- Supplied with Certificate of Analysis documentation
- Lyophilized using standard pharmaceutical-grade freeze-drying processes
- Lot-tracked for research traceability and compliance documentation
Sourcing GLP-3 for Your Lab
Peppy University supplies research-grade GLP-3 (Retatrutide) in two sizes for different research applications:
- GLP-3 10mg — suitable for initial dose-response studies and smaller research protocols
- GLP-3 30mg — best value for extended research protocols requiring higher total peptide volume
Both available with 99% purity, HPLC verified COA, and same-day processing with 2-3 day delivery.
All products at Peppy University are intended strictly for laboratory and scientific research purposes only. Not for human consumption. Research Use Only.
