Application Guide
How to safely and correctly reconstitute and use your research peptides.
What you need
Peptide Vial
Lyophilised peptide powder in original packaging
BAC Water
Bacteriostatic water for reconstitution (available in our shop)
Insulin Syringe
Sterile disposable insulin syringe 1 ml (27G) for precise dosing
Alcohol Swabs
Sterile alcohol wipes for disinfecting the septum
Protective Gloves
Latex or nitrile gloves for clean handling
Dosage Calculator
Use our Peptide Calculator for accurate calculations
Reconstitution Step by Step
Tempering
Remove the peptide vial from the refrigerator and let it come to room temperature for 15–30 minutes. This prevents condensation when opening, which could damage the powder.
Calculate dosage
Calculate the required amount of BAC Water using our Peptide Dosage Calculator. Example: 10 mg peptide + 2 ml BAC Water = 5 mg per ml (500 µg / 0.1 ml).
Disinfect the septum
Wipe the rubber septum of the peptide vial and the septum of the BAC Water vial each with a fresh alcohol swab. Let the alcohol dry for 10–15 seconds before inserting the needle.
Draw up BAC Water
Insert the sterile insulin syringe through the septum of the BAC Water vial and draw up the calculated amount. No air bubbles — hold the vial inverted and gently tap the syringe to dislodge bubbles.
Reconstitute the peptide
Insert the needle through the disinfected septum of the peptide vial and let the BAC Water flow slowly along the glass wall — do not inject directly onto the powder. This keeps the peptide structure intact.
Dissolve & check
Gently roll the vial between your fingers until the powder has completely dissolved. The solution should be clear and colourless. If it remains cloudy or particles are visible, something is not correct.
Label & store
Write the reconstitution date on the vial. Store the solution immediately in the refrigerator at 2–8 °C. Shelf life: typically 14–28 days.
