Peptides are fragile and degrade quickly from heat, light, moisture, and agitation. Lyophilized peptides are stable short-term at room temperature but require -20°C storage long-term. Reconstituted peptides must be refrigerated (2–8°C) and handled gently. Avoid UV exposure, contamination, and temperature fluctuations. Using high-quality, verified peptides is essential for reliable research results.
Peptides are fragile biological chains. Without proper care, heat, light, and moisture can cause rapid degradation, rendering your research peptides ineffective before your experiment even begins.
Whether you are working with TB-500, MOTS-c, or other compounds, following strict storage protocols is vital for maintaining the integrity of your 99% pure peptides.
Handling Lyophilized (Powder) Peptides
Most peptides from Platinum Lion Peptides arrive in a lyophilized (freeze-dried) state. This powder form is the most stable.
- Room Temperature: Lyophilized peptides are generally stable at room temperature for short periods (during shipping), provided they are kept away from direct sunlight.
- Long-Term Storage: For storage longer than a few weeks, vials should be stored in a freezer at -20°C.
- Moisture Control: Always keep vials strictly sealed until use. We vacuum-seal our products for optimum storage during transit.
Reconstitution and “Wet” Storage
Once a peptide is reconstituted with a solvent (commonly bacteriostatic water), its stability clock starts ticking.
- Refrigeration is Mandatory: Reconstituted peptides must be stored at 2°C to 8°C (standard refrigeration). Do not freeze reconstituted peptides, as the freeze-thaw cycle can damage the peptide structure.
- Minimize Agitation: Peptides are sensitive to mechanical stress. Do not shake the vial vigorously. Instead, gently swirl the vial until the lyophilized cake is fully dissolved.
Factors That Cause Peptide Degradation
- UV Light: Direct exposure to sunlight can break chemical bonds.
- Contamination: Always wipe the rubber stopper with an alcohol pad before inserting a needle to prevent introducing bacteria into the sterile environment.
- Temperature Fluctuations: Keep your lab fridge at a consistent temperature.
Source Quality Matters
Even the best storage techniques cannot fix a strictly low-quality product. Start with the best materials. Platinum Lion Peptides provides third-party tested, HPLC-verified compounds designed for rigorous in-vitro research.
