Frequently Asked Questions

How do I reconstitute a peptide? Reconstitution means adding bacteriostatic water to the lyophilised powder. Concentration (mg/mL) equals the vial mass in mg divided by the millilitres of water added - for example a 10 mg vial with 2 mL of bacteriostatic water gives 5 mg/mL. See the reconstitution guide and use the calculator for exact volumes. This is research-preparation information, not human dosing guidance.

How much bacteriostatic water do I add to a peptide? It depends on the concentration you want: more water means more units per dose, less means fewer, and the total mg in the vial is unchanged. The reconstitution calculator pre-fills a volume that places a typical research dose at a readable syringe mark.

How should peptides be stored? Lyophilised (powder) vials are generally kept cold and protected from light; once reconstituted they are refrigerated and used within a limited window. See the storage guide for specifics. This is research-use-only handling information.

How long do reconstituted peptides last? Shelf life depends on the compound, temperature and handling; a reconstituted vial is refrigerated and degrades faster than the sealed lyophilised powder. The storage guide covers typical handling windows. General research information, not medical advice.
