Manufacturing Process
At Prime Vitality Inc (Prime Peptides), we are dedicated to producing high-quality research-grade peptides with exceptional purity and consistency, ensuring stringent quality control at every stage. Every batch is independently tested by Janoshik Analytics and finished at our Hamilton, NSW facility.
High-Purity Water Usage
The process begins with the dissolution of peptides in WFI (Water for Injection) grade water — the highest purity standard available. This ensures a clean and contamination-free foundation for our products.
Excipients for Stability
To enhance stability, mannitol and sucrose are added as excipients. Mannitol serves as a bulking agent, while sucrose acts as a lyoprotectant, preventing degradation and aggregation throughout the freeze-drying and storage process.
Electrospray Ionisation (ESI)
During the ESI process, the peptide solution is sprayed into a fine mist. Sodium ions are introduced and attach to peptide molecules, facilitating ionisation. This controlled process plays a crucial role in enhancing stability and characterisation.
Sterile Filtration
Following ionisation, the peptide solution undergoes sterile filtration through a 0.22 µm PES (polyethersulfone) filter membrane to remove any potential contaminants and ensure a high level of purity.
Precise Vialing & Freeze-Drying
Once filtered, the solution is precisely dispensed into 3 mL vials. The vials are partially stoppered and placed into a freeze-dryer for a carefully controlled 36-hour lyophilisation cycle:
- Freezing Phase: Solution cooled to −40 °C, stabilising the peptide structure.
- Primary Drying: Water removed through sublimation, eliminating the majority of moisture.
- Secondary Drying: Remaining bound water removed via desorption.
Frequently Asked Questions
How are Prime Peptides manufactured?
Our peptides are manufactured using WFI-grade water, ESI ionisation, 0.22µm sterile filtration, and a 36-hour lyophilisation cycle. All finishing takes place at our facility in Hamilton, NSW.
What purity standards do you follow?
We use Water for Injection (WFI) grade water, add mannitol and sucrose as stabilising excipients, and filter through 0.22µm PES membranes. Each batch is independently tested by Janoshik Analytics.
Where are your peptides finished?
All processing, packaging, and distribution take place at our facility in Hamilton, NSW, Australia. Our Australian-based team handles final formulation and quality control.
Are your peptides tested for purity?
Yes. Every batch undergoes rigorous third-party purity testing by Janoshik Analytics. Certificates of Analysis (COAs) are available on every product page.
