When you source CAS 137359‑89‑8 Cetrorelix from fragmented distributors, three critical issues almost always surface:
- Sky‑rocketing API costs – Traditional suppliers add 30‑45% markup to cover “handling fees,” pushing your per‑cycle expense beyond budget.
- Inconsistent batch purity – Variability in HPLC purity (often 96‑98% instead of ≥99.5%) forces you to run additional QC, delaying release to market.
- Lengthy lead‑times & freight bottlenecks – 6‑8 weeks from order to delivery is the norm, jeopardizing time‑sensitive clinical trials.
According to a 2025 industry survey, 37% of IVF clinics reported a “critical shortage” of GnRH antagonists due to these exact issues. The result? Cancelled cycles, lost revenue, and damaged brand reputation.
Resolve these risks now with a single, compliant source.
