### Storage Shelf Life: Up to 2 Years with Proper Storage

The standard storage shelf life of this peptide is 24 months, or 2 years, provided that strict storage requirements are followed. Unreconstituted lyophilized powder should be stored in a sealed container in a cool, dry environment at 2-8℃, avoiding direct sunlight and air exposure to reduce the damage to peptide bonds caused by ultraviolet radiation and humidity. Its purity is typically maintained above 98%. This high purity, combined with sealed glass packaging, ensures stable biological activity throughout the shelf life. Exceeding the storage temperature or frequent opening may lead to peptide molecular degradation, shortening the shelf life by 30%-50%.
### Duration of Action in Vivo: Long-lasting Regulation of Cellular Senescence
Compared to natural Epitalon, the structural modification of N-Acetyl Epitalon Amidate significantly prolongs its duration of action in vivo. It delays telomere shortening by activating telomerase, and this cellular-level regulatory effect can last for several weeks. Studies show that after a single dose, its effects on circadian rhythm regulation and melatonin secretion can last for 1-2 weeks, while its anti-oxidative stress and DNA repair support effects can continue for 3-4 weeks. This long-lasting effect stems from the modified molecule being more easily absorbed and resistant to degradation by peptidases in vivo, with a half-life approximately 1.5 times longer than the original peptide.
### Key Usage Tips
This peptide is currently only for scientific research. After reconstitution, it should be used as soon as possible to ensure activity. Its long-lasting effect is not "permanent," and the natural process of cellular senescence will continue. Regular dosing is necessary to maintain the regulatory effect. Furthermore, temperature control and light protection during storage and use are crucial to ensuring its shelf life and efficacy; improper handling at any stage may weaken its biological activity.
