Glutathione

Storage:

All of our manufacturing partners produce peptides using the Lyophilization (Freeze Drying) process, ensuring agents maintain stability for shipping and storage for 12+ months.

In lyophilized form, they are shelf-stable for many weeks. However, for long-term storage, it is recommended to store them in the freezer.

We often hear concerns about the standard "discard after 28 days of first use" disclaimer. Don't worry, this has nothing to do with studies regarding the efficacy of specific peptides. 28 days is the FDA requirement for producers of multi-use vials to prove their bacteriostatic maintains efficacy. This minimum requirement becomes the de facto standard.

In our experience, if you use proper sterile procedures and refrigerated storage, you can continue sampling from the same reconstituted vial for 3+ months.
