- Purity (HPLC)
- 95–97%
- ≥98%
- ≥98% with COA per batch
- Compounded preparations undergo stricter post-purification QC. Commercial batches average 2–3% higher impurity levels
- Concentration Options
- Fixed (1 mg or 2 mg per vial)
- Customizable (0.5 mg to 10 mg per vial)
- Fully custom, any mass per vial
- Custom concentrations eliminate multi-step dilutions that introduce error
- Buffer System
- Phosphate or proprietary
- Selectable (phosphate, acetate, citrate, Tris)
- Any buffer compatible with peptide stability
- Buffer selection matters for metal-ion studies and pH-sensitive protocols
- Reconstitution Volume
- Standardized (typically 2 mL)
- Adjustable (100 μL to 5 mL)
- Specified per protocol needs
- Low-volume reconstitution is critical for small-animal dosing
- Lyophilization Atmosphere
- Standard air
- Inert (nitrogen or argon)
- Inert with real-time O₂ monitoring
- Oxygen exposure during lyophilization accelerates methionine oxidation
- Antioxidant Inclusion
- Rarely included
- Methionine or ascorbic acid standard
- Optional, based on storage duration
- Extends post-reconstitution stability by 15–20%
- Batch Size
- 1,000–10,000 vials
- 50–500 vials
- 10–100 vials
- Smaller batches allow mid-run formulation adjustments
