How to Use the Peptide Calculator
- Enter Peptide Amount: Input the total amount of peptide in your vial (in mg or mcg).
- Enter BAC Water Volume: Input how much bacteriostatic water you will add (in ml).
- Enter Desired Dose: Input your target dose for research purposes.
- Read the Result: The calculator will show exactly how much solution to draw, with a visual syringe guide.
Understanding Peptide Reconstitution
Peptide reconstitution is the process of dissolving lyophilized (freeze-dried) peptide powder into a liquid solution using bacteriostatic water. This process is essential for research applications as it allows for precise measurement and administration of peptide doses.
The concentration of your reconstituted peptide depends on two factors: the total amount of peptide in the vial and the volume of bacteriostatic water added. Our calculator uses this simple formula:
Volume to Draw (ml) = Desired Dose (mcg) ÷ Concentration (mcg/ml)Where concentration = Total Peptide Amount ÷ Total BAC Water Volume
Tips for Accurate Reconstitution
- 1.Always use bacteriostatic water (BAC water) for reconstitution as it contains a preservative that prevents bacterial growth.
- 2.Add the water slowly, allowing it to run down the side of the vial rather than directly onto the peptide powder.
- 3.Gently swirl the vial to mix - never shake vigorously as this can damage the peptide structure.
- 4.Store reconstituted peptides in the refrigerator (2-8°C) and use within the recommended timeframe.
- 5.Use insulin syringes (typically U-100) for precise measurements - 1ml = 100 units.
Frequently Asked Questions
How much BAC water should I add?
The amount of BAC water depends on your desired concentration. Common amounts are 1ml, 2ml, or 3ml. More water creates a more dilute solution (easier to measure small doses), while less water creates a more concentrated solution (fewer injections needed).
How long does reconstituted peptide last?
When stored properly in a refrigerator at 2-8°C, most reconstituted peptides remain stable for approximately 4-6 weeks when using bacteriostatic water. Always check for cloudiness or particles before use.
What syringe should I use?
Insulin syringes (U-100) are recommended for their precision. On these syringes, 100 units equals 1ml, and each small marking represents 1 unit (0.01ml). Our calculator provides readings in both ml and units for convenience.
