Maintaining the integrity of peptides through proper storage is crucial for preserving their highest quality.

It is advised to keep peptides in either a refrigerator or freezer, although they can remain stable at room temperature for up to a month, which varies with their sequence length and other factors. Here are the recommended storage instructions:

For Reconstituted (mixed) Peptides: Store these in the refrigerator at temperatures ranging from 2 to 8 degrees Celsius. They should be used within 3 to 8 weeks after mixing, depending on the peptide sequence.

For Unmixed Peptides: When in powder (lyophilized) form, these vials should be kept frozen at temperatures between 0 and -20 degrees Celsius. They will stay stable for up to 48 months (4 years) when stored in the freezer. It is preferable to use them within 18 months from the date of purchase for optimal quality.

While unmixed vials can be stored in the freezer for up to four years, storing them in the refrigerator is advisable if you plan to use them within 1 to 3 months, as repeated cycles of freezing and thawing may degrade the peptides.

We strongly advise adhering to a precise mixing process. Before introducing any mixing solution, ensure that both the peptide and the solution are at room temperature. This ensures the peptides are mixed thoroughly each time. Carefully pour the mixing solution into the vial, aiming to let the solution run down the side of the vial to safeguard the peptide. Afterward, lightly swirl the vial and then store it in a refrigerator for 24 hours. Following this period, the peptide will be prepared for use.

No, we do not offer advice on which to buy.

You should choose your peptide based on your research needs. There are many research papers online available to sample from.
