Step-by-step instructions for properly handling, reconstituting, and storing research peptides
Gather these items before beginning the reconstitution process
Follow these steps for proper peptide reconstitution
Remove the lyophilized peptide vial from the freezer and allow it to sit at room temperature for 10-15 minutes to prevent condensation.
Wipe the rubber stopper with an alcohol swab and allow it to dry completely to maintain sterility.
Using a sterile syringe, draw the required amount of bacteriostatic water. Never shake the vial — swirl gently instead.
Insert the needle into the center of the stopper and slowly inject the water against the glass wall, not directly onto the powder.
Gently swirl the vial (do not shake) until the peptide is fully dissolved. This may take 1-5 minutes.
Refrigerate reconstituted peptide at 4°C (39°F). Use within 30 days.
Calculate the correct dosage based on peptide concentration and desired dose
Volume to draw per dose
Lyophilized: -20°C (freezer)
Reconstituted: 4°C (refrigerator)
Avoid repeated freeze-thaw cycles
Always use sterile bacteriostatic water (0.9% benzyl alcohol) for reconstitution to prevent bacterial growth during storage.
Most reconstituted peptides remain stable for 30-60 days when refrigerated. Always check specific product recommendations.
Always use aseptic technique when handling peptides. Wear gloves and safety glasses. Never reuse needles or syringes. Dispose of sharps properly in an approved sharps container. If you experience any adverse reactions, seek immediate medical attention. These products are for research purposes only and are not for human consumption.
