Certificate of Analysis
Every batch undergoes independent third-party laboratory analysis to verify identity, potency, and safety. Testing includes quantitative assay verification, heavy metals screening, and comprehensive microbial analysis.
View Certificate of AnalysisStorage Instructions
All products from LGI peptides are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.
Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.
Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.
Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.
