- Research-Grade Lyophilized Thymalin
- −20°C (standard freezer)
- 12–24 months
- Bacteriostatic water, 45-degree wall injection technique
- Moisture ingress from repeated freezer access, freeze-thaw cycles
- Longest stability with lowest handling complexity. Ideal for labs conducting multi-month studies
- Reconstituted Thymalin (Research)
- 2–8°C (refrigerator)
- 28 days maximum
- 0.9% benzyl alcohol bacteriostatic water
- Temperature excursions during storage, exceeding 28-day window
- Requires strict refrigeration discipline but allows flexible dosing schedules within the window
- Clinical-Grade Peptides (Comparison)
- 2–8°C (pharmaceutical-grade refrigeration with monitoring)
- Manufacturer-specified, typically 30–90 days reconstituted
- USP-grade sterile water or manufacturer-provided diluent
- Temperature deviation alerts, contamination from multi-dose vial access
- Higher regulatory oversight and monitoring but not substantively more stable than research-grade when handled correctly
- Room-Temperature Storage (Incorrect)
- 20–25°C
- Potency drops to <70% within 7 days
- Not applicable
- Enzymatic degradation, oxidation, bacterial proliferation in reconstituted form
- Never acceptable for thymalin. Irreversible potency loss within one week
