- Reconstitution Water
- Sterile water for injection
- Bacteriostatic water (0.9% benzyl alcohol)
- Sterile water must be discarded within 24 hours; bacteriostatic water remains sterile for 28 days after opening
- Bacteriostatic water is non-negotiable for multi-dose protocols. Sterile water is appropriate only for single-use applications
- Syringe Gauge
- 21-gauge standard needle
- 27–30 gauge insulin syringe
- Larger needles create shear forces that denature peptide chains; insulin syringes minimise mechanical stress and provide 0.01mL precision
- Always use insulin syringes for peptide work. The cost difference is negligible and the precision gain is substantial
- Storage Container
- Standard refrigerator
- Medication cooler with thermometer
- Kitchen refrigerators experience 2–10°C swings; dedicated coolers maintain 2–8°C stability
- If storing reconstituted peptides for more than 72 hours, temperature logging becomes essential. Guessing based on refrigerator settings leads to degraded compounds
- Vial Access Technique
- Drawing without cleaning stopper
- Alcohol swab before every draw
- Each needle puncture introduces contamination risk; cleaning the rubber stopper with 70% alcohol before every draw reduces bacterial introduction by 90%
- This is the single most overlooked step in peptide handling. Skipping it compromises the entire batch
