Storage Instructions
All products from Vitae 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.

Mechanism of action
In in vitro and preclinical studies, Thymalin is used to investigate mechanisms of T-cell differentiation, CD4/CD8 ratio modulation, interleukin-2 receptor expression, and natural-killer-cell activity. Research has characterized the preparation's effects on thymic-derived immune signaling, and it is widely used as a comparator to defined thymic peptides such as Thymosin Alpha-1 and Thymopentin.
Storage & handling
Lyophilized powder vial intended for research use — this is not a capsule or oral supplement. Store the unreconstituted vial at -20°C in a dry, light-protected environment for long-term stability. Once reconstituted with bacteriostatic water, refrigerate at 2-8°C and use within 30 days. Do not freeze reconstituted solution.
