Method
How to reconstitute, step by step
- Step 1
Bring vials to room temperature
Let the lyophilized peptide and bacteriostatic water sit out for 15–20 minutes before mixing.
- Step 2
Sanitize both stoppers
Wipe each rubber stopper with a fresh alcohol swab and let it air dry.
- Step 3
Draw your diluent
Pull the calculated volume of bacteriostatic water into a sterile syringe.
- Step 4
Add water slowly
Angle the needle so the stream runs down the inside glass wall — never directly onto the powder.
- Step 5
Swirl, never shake
Roll the vial gently between your fingers until fully clear. Shaking can shear the peptide.
- Step 6
Label and refrigerate
Mark the date and concentration, then store at 2–8°C and protect from light.
Reference
Conversions & storage
Quick conversions
- 1 mg = 1,000 mcg
- 1 mL = 100 units on a U-100 insulin syringe
- 10 units = 0.10 mL
- 1 lb = 0.4536 kg
- Concentration (mg/mL) = vial strength ÷ diluent volume
- Units to draw = (dose ÷ concentration) × 100
Storage guidance
- Lyophilized (unmixed): stable at -20°C long term; room temp for short transit.
- Reconstituted: 2–8°C, typically used within 28–30 days.
- Always use bacteriostatic water for multi-draw vials; sterile water is single-use.
- Protect from light and avoid repeated freeze/thaw cycles.
