Six steps from sealed lyophilized vial to a properly stored, ready-to-dose solution.
Use the calculator above to decide how many mL of bacteriostatic water to add — common volumes are 1, 2, or 3 mL. Smaller volume → higher concentration → smaller pull.
Wipe the rubber stopper on both the peptide vial and the bacteriostatic water vial with a fresh alcohol swab. Let air-dry for 30 seconds.
Pull the calculated water volume into a 1 mL insulin syringe. Tip the bacteriostatic water vial upside down to draw fully without sucking air.
Angle the needle so the water runs down the inside wall of the peptide vial. Do not spray water directly onto the powder — high pressure can denature the peptide.
Roll the vial between your palms or gently swirl until the powder fully dissolves. Shaking creates foam and can damage delicate peptide bonds.
Write the reconstitution date on the vial. Store at 2-8°C. Most reconstituted peptides remain stable for 28 days in bacteriostatic water.
A peptide dosage calculator converts the vial size (mg or IU), the volume of bacteriostatic water you reconstitute it with, and your target dose into the exact pull volume on an insulin syringe. The formula is: pull volume (mL) = dose (mcg) ÷ (vial size (mcg) ÷ water volume (mL)). PinnyPeptide expresses the result both in mL and in insulin units (100 units = 1 mL) so you can read it directly off the syringe barrel.
A 5 mg vial reconstituted with 2 mL of bacteriostatic water has a concentration of 2,500 mcg/mL. A 250 mcg dose is therefore 0.1 mL, which is 10 units on a 0.5 mL insulin syringe.
For doses under 30 units, use a 0.3 mL (30 u) syringe — the wider tick spacing makes small pulls more precise. For 30-50 unit pulls use a 0.5 mL syringe. Reserve the 1 mL syringe for unusually large pulls or for the reconstitution step itself. Needle gauge for subcutaneous peptides is typically 29-31 G, length 5/16″ or 1/2″.
Yes. Switch the unit type to IU and enter the vial total in IU and the dose in IU. The math is unit-agnostic — concentration is calculated in IU/mL and pull volume is converted to insulin syringe units.
Most peptides reconstituted in bacteriostatic water (which contains 0.9% benzyl alcohol as a preservative) remain stable for 28 days refrigerated at 2-8°C. Peptides reconstituted in plain sterile water without preservative should be used within 24-72 hours. Always protect from light and avoid freezing reconstituted solutions.
