This comparison does not assign a generated winner or score.
- Cold Shock Haze
- Uniform translucent haze appearing immediately upon reconstitution with cold solvent
- Temperature differential between cold bacteriostatic water and room-temp peptide
- Fully reversible. Clears within 10–15 minutes at room temperature
- 95–100% potency retained
- Allow vial to warm to 18–22°C, swirl gently. Cloudiness should resolve
- Reversible Aggregation
- Milky opalescence appearing 6–12 hours post-reconstitution, uniform distribution, no particles
- Suboptimal reconstitution technique (too-fast injection, slight pH mismatch, ionic strength variation)
- Partially reversible. May improve 20–40% after 24h refrigeration at 2–8°C
- 80–90% potency retained
- Refrigerate for 24h and reassess. If clarity improves, peptide is viable for research use
- Irreversible Aggregation
- Visible particles, flocculation, or sediment settling to vial bottom; cloudiness doesn't improve with refrigeration
- Freeze-thaw cycles, prolonged temperature excursion (>6h above 25°C), or extreme pH shift
- Not reversible. Protein structure permanently altered
- <50% potency retained, unreliable dosing
- Discard vial. Aggregated peptide cannot be re-solubilised and potency is compromised
- Microbial Contamination
- Cloudiness with yellow/brown discolouration, may have odour, often accompanied by visible particles or 'strings'
- Sterile technique breach, prolonged storage above 8°C, needle reuse, or compromised bacteriostatic water
- Not reversible. Bacterial enzymes actively degrade peptide
- Unknown and unsafe. Proteolytic enzymes fragment the peptide unpredictably
- Discard immediately. Contaminated peptide poses research integrity and safety risks
