Frequently Asked Questions
Which peptide APIs does Winhycare Pharma supply?
Five peptide APIs are supplied to pharmaceutical manufacturers and developers: semaglutide, tirzepatide, retatrutide, cagrilintide and BPC-157. Every molecule in the peptide table, plus custom peptides, is also supplied for research use only to research organisations and individual researchers. Research-grade material is not for human or veterinary use and is not a GMP API.
What is a CRDMO, and how do you work with partners?
A CRDMO partner provides process development, analytical and regulatory services around an API programme. Winhycare Pharma works as your peptide CRDMO partner (sequence and process optimisation, analytical method development, and DMF/CTD documentation) and supplies Semaglutide API, so peptide programmes are de-risked end to end.
What purity and impurity control should we expect for Semaglutide API?
A target release purity of ≥99.0% by UPLC/HPLC, with individual impurities controlled below 0.10%, confirmed by LC-MS impurity profiling and supported by ICH Q1A(R2) stability data. Each batch ships with a Certificate of Analysis.
Do you support US-DMF and CTD Module 3 filings?
Yes. We support US-DMF Type II dossiers, CTD Module 3 CMC sections, ICH Q2(R1) analytical method-validation packages and stability data, and provide a support desk to help resolve regulator deficiency letters during your filing.
Can you validate our injectable formulation facility?
Yes. We provide qualification and validation services for injectable formulation facilities: a Master Validation Plan, IQ/OQ/PQ execution, facility (HVAC, cleanroom classification) and utility (PW, WFI, gases) validation, aseptic media fills, cleaning validation and computer-system validation (21 CFR Part 11), aligned to WHO TRS 986 Annex 2, EU GMP Annex 15 and USFDA 21 CFR Part 211.
How do you handle global shipping of temperature-sensitive API?
Semaglutide API is shipped through validated cold-chain logistics with active temperature monitoring, thermal packaging and customs documentation for the US, Europe and Asia, with standing supply and safety-stock options to protect your production schedule.
