- Storage Temperature Before Reconstitution
- −20°C (lyophilised powder), then 4–6°C briefly before mixing
- Room temperature (22–25°C) for 20+ minutes before mixing
- 12–18% bioactivity loss before reconstitution even begins due to glycosidic bond hydrolysis
- Temperature discipline starts before the vial opens. Not after. Most degradation we document happens during the 'I'll mix it in a minute' delay.
- Solvent Addition Speed
- 0.5–1.0 mL per 10 seconds, directed at vial wall, gentle swirling after each addition
- Full volume added rapidly in 5–10 seconds, injected directly onto powder
- Protein aggregation and foaming reduce bioavailability by 30–60%. Aggregates cannot cross cell membranes
- Mechanical stress denatures peptides faster than temperature or pH errors. Slow addition isn't optional.
- Reconstituted Solution Storage
- 2–8°C (refrigerator), protected from light, used within 28 days
- Countertop storage at room temp between doses, or freezing reconstituted solution
- Room temp: 25–40% loss per 48 hours. Freezing: ice crystal formation ruptures molecular structure completely
- Once mixed, NAD+ is no longer shelf-stable. Treat it like insulin. Refrigerate immediately, never freeze.
- Needle Reuse Between Vial Access
- Fresh needle for each vial entry and each injection
- Same needle used to draw from vial and inject, or reused across multiple doses
- Bacterial contamination risk increases 40–70% with each reuse; rubber particulates introduced into solution
- Needle tips aren't sterile after the first puncture. Benzyl alcohol preservative doesn't compensate for repeated contamination.
