This comparison does not assign a generated winner or score.
- Visual appearance
- Yellow/brown discoloration, possible cloudiness from aggregation
- Cloudiness with rapid progression, visible particulates, biofilm
- Clear solution, no visual abnormalities
- Degradation shows gradual colour shift; contamination appears suddenly and worsens daily; counterfeit looks normal but performs zero function
- Odour
- Neutral or faint chemical smell
- Sour, musty, or putrid odour
- Neutral
- Bacterial contamination produces detectable odour within 48–72 hours; peptide degradation is odourless
- Tanning response
- Weak or absent despite proper dosing
- Weak/absent (if peptide concentration drops due to dilution)
- Completely absent from day one
- Degraded MT-2 may produce partial response initially then fade; contamination doesn't affect receptor binding but may reduce usable peptide; counterfeit never works
- Injection site reaction
- Minimal (unless oxidised peptide fragments trigger localised inflammation)
- Redness, swelling, heat, possible abscess formation
- Minimal to none
- Contaminated peptide causes immune response at injection site; degraded peptide rarely does unless severe oxidation occurred
- Storage history
- Likely temperature excursion or prolonged storage beyond 28 days post-reconstitution
- Non-sterile reconstitution, reused needle, compromised vial seal
- N/A. Product was never viable
- Degradation correlates with time and heat; contamination correlates with procedural error during handling
- Reversibility
- Irreversible. No way to restore broken peptide bonds
- Irreversible. Bacterial growth cannot be undone
- N/A
- Neither degradation nor contamination can be fixed once they occur; discard and replace
