Frequently Asked Questions

Is DSIP third-party tested?

Yes. Every batch is third-party tested to ≥99% HPLC purity, with a Certificate of Analysis on every batch and documentation published in the Bolt Peptide COA Library.

How should DSIP be stored?

Keep the lyophilized vial cool and out of direct light. For short periods, room temperature away from light is acceptable; for longer storage, refrigerate or freeze. Once reconstituted, keep refrigerated and use within your validated window.

How is a lyophilized peptide reconstituted?

Add bacteriostatic or sterile water slowly down the inside of the vial wall, then swirl gently (do not shake) until fully dissolved. Calculate the volume needed to reach your target research concentration.

Is DSIP intended for human use?

No. All Bolt Peptide products are supplied strictly for laboratory and scientific research use only, not for human or veterinary use, consumption, or therapeutic application.

How fast does Bolt Peptide ship?

Orders process in 3-4 business days and ship within the United States. Orders of $100 or more qualify for free shipping.
