For maximum shelf life and integrity, lyophilized peptides should be stored in a sealed vial at refrigerated or frozen temperatures prior to reconstitution.
- Preferred storage: –20°C (freezer)
- For long-term preservation and maximum degradation prevention: –80°C (ultra-low freezer)
Avoid frequent freeze-thaw cycles, exposure to humidity, or light. Once reconstituted, compounds should be used promptly and stored only as your protocol or lab guidelines allow.

My package says delivered but I have not received it. What should I do?
Although carrier issues are beyond our scope of our control, we recommend looking around your property for the package. Sometimes carriers leave parcels in inconspicuous areas for safety reasons or they may have delivered to a neighbor next door. Rest assured, we want you to receive your items. If your package says delivered but you have not received it you must complete the following steps in order for us to reship your items out.
1. Contact your local post office or if you have a relationship with your delivery person, ask them to check their truck/facility.
2. File a lost package claim with your carrier. You can use the link here: https://onlineclaims.usps.com/ All of the information you need to file your claim can be found in the tracking email that we sent to you.
3. The carrier will provide you with a claim number or confirmation email of your claim being filed. Please forward a copy of the claim number or screenshot of the confirmation email and our shipping department will discuss your reshipment.
