- Crystal-clear, no particulates
- Proper reconstitution and storage
- Intact. Full bioactivity
- Yes
- This is the only acceptable appearance for reconstituted MK-677 throughout the 28-day refrigerated shelf life.
- Slight haziness within 24 hours of mixing
- Incomplete dissolution or cold water used
- Questionable. May resolve with gentle warming to 4–6°C
- Potentially. Observe for 12 hours
- If haziness doesn't clear within 12 hours at stable refrigeration, discard it.
- Visible cloudiness 3+ days post-reconstitution
- Temperature excursion above 8°C or bacterial growth
- Compromised. Protein aggregation likely
- No
- Cloudiness after proper initial reconstitution indicates degradation. Efficacy is lost and contamination risk is present.
- Particulate matter or floating debris
- Coring from rubber stopper, undissolved powder, or contamination
- Severely compromised
- Particulates are either insoluble aggregates or foreign matter. Both render the solution unsafe.
- Cloudiness + unusual odor
- Bacterial contamination from non-sterile water or moisture exposure pre-reconstitution
- Complete failure
- Absolutely not
- Odor signals bacterial metabolic byproducts. This vial is contaminated and must be discarded immediately.
