Research peptides ship as a lyophilized (freeze-dried) powder that must be dissolved before it can be measured. Reconstitution is the process of adding a sterile diluent — usually bacteriostatic water — to bring the powder into solution at a known concentration.
What the process involves
- Let the vial and diluent reach room temperature.
- Sanitize both rubber stoppers with an alcohol swab.
- Draw your chosen volume of bacteriostatic water.
- Add the water slowly against the inside wall of the vial — never spray it directly onto the powder.
- Let it dissolve on its own or swirl gently. Do not shake.
- Store the reconstituted vial refrigerated and protected from light.
From volume to a measurable dose
Once dissolved, the concentration is fixed by two numbers: the milligrams in the vial and the millilitres of water you added. Our reconstitution calculator turns those into the exact units to draw on an insulin syringe, and the mg / mcg / IU converter handles any unit conversions along the way.
Choosing a water volume
There is no single “correct” volume — more water simply makes each dose a larger, easier-to-read draw. If your target measurement lands between the marks on your syringe, adjust the water volume and recalculate until it sits on a clean line.
Storage and stability
Reconstituted with bacteriostatic water and kept refrigerated and away from light, many research peptides remain usable for a few weeks, though this varies by compound. Always follow the stability data supplied with your specific material.
