Controlled Lyophilization Cycles
Protocols engineered around each peptide's thermal profile — shelf temperature, vacuum ramps, and hold times optimized to protect structure and extend shelf stability.
Custom Formulations
Concentrations, buffer systems, excipients, and blend ratios tailored to your project, documented with batch records and analytical targets.
Verified Material Procurement
Raw inputs sourced through a vetted supplier network and analytically verified to 98%+ purity before production.
End-to-End Packaging
Sterile vialing, capping, custom labeling, kitting, and shipper-ready packaging — all in one US facility.
Process
Project Review
Target peptide, concentration, fill volume, and stability requirements define the cycle.
Cycle Development
Engineering batches verify cake structure, reconstitution, and moisture content.
Controlled Lyophilization
Validated cycles with real-time monitoring and full batch records.
Fill, Cap & Finish
Vialing, capping, and secondary packaging completed in-house.
QC & Release
Analytical testing and Certificate of Analysis documentation on every lot.
Domestic Logistics
