How should I store the products?

Peptides are sensitive compounds. This means they can lose structure or effectiveness if exposed to excess heat, light, agitation, or improper handling. Because of this sensitivity, many peptides are supplied in a dry, powdered form, which helps preserve their stability during storage and transport. 

This dry form is more durable and allows the peptide to remain intact until it is ready to be prepared for use. 

When the term reconstitution is used, it simply describes the process of preparing that dry powder into a liquid solution. This step allows the peptide to be used in a controlled and measurable way. Reconstitution does not change what the peptide is — it only changes its form. 

Even though reconstitution is a straightforward process, care still matters. Gentle handling helps maintain the integrity of the compound and reduces the risk of degradation or contamination. Proper preparation supports consistency, accuracy, and stability throughout use. 

In short, reconstitution is about protecting the peptide so it can function as intended — nothing more, nothing less.
