How to Store Peptides Properly Powdered Peptides Store in the refrigerator or freezer Reconstitute only when ready to use Shelf life: Up to two years when stored cold Reconstituted Peptides Store consistently in the refrigerator Shelf life: Typically 36 months when handled properly Nasal Sprays and Creams Store consistently in the refrigerator Shelf life: Nasal sprays: 36 months refrigerated Creams: Approximately 6 months refrigerated Avoid repeated freezing and thawing whenever possible

Nasal spray delivery Nasal spray delivery offers an alternative route that avoids both the skin barrier and digestive degradation

It plays a critical role in cellular energy production and protects cells from oxidative damage

Allow the vial to sit undisturbed for 35 minutes while the peptide dissolves passively do not shake or vortex, as mechanical shear stress denatures peptide structure

This stability profile distinguishes it from many peptide-based research compounds and has contributed to interest in its biochemical persistence, signaling activity, and pathway-specific effects in mechanistic investigations

Leaving your reconstituted vial on the counter even briefly accelerates deterioration
