Storage by product format and how to read the mixed date
Storage instructions depend on the presentation. Check the product label and its specific expiry; a single generic shelf life does not describe every peptide or format.

Dry powder vials: −20°C
Store the lyophilized powder at −20°C, dry and protected from light. Once reconstituted, follow the product label’s storage and expiry instructions. Do not apply the dry-powder freezer instruction to a ready-mixed product.
Dual cartridges: 2–8°C
Keep filled dual-chamber cartridges refrigerated at 2–8°C, including before activation. Powder and supplied liquid remain separate until activation. Follow the cartridge label for its expiry and handling instructions.
Ready-mixed pens: 2–8°C
Keep Supreme multi-dose and Calyssee ready-mixed pens refrigerated continuously at 2–8°C. The approximate stability window is 30–45 days from mixing, depending on the peptide. The product-specific expiry on the label takes precedence.
Mixed date is not first-use date
For these ready-mixed pens, the stability clock starts when the liquid was mixed, even if the customer has not opened the cartridge. Check the mixed date and expiry when the product arrives. Ask support if the date is missing or unclear.
BAC water and nasal sprays
Keep BAC water refrigerated at 2–8°C and follow its label’s expiry and discard instructions. Store nasal sprays at room temperature according to their labels. The approximate pen stability window is not assigned to BAC water, sprays or sealed dual cartridges.
