Adding my CompoundPharm data points:
5 orders over 8 months, all lyophilized semaglutide 10mg:
- Oct 2025: 98.5% (Janoshik)
- Nov 2025: 99.0% (Janoshik)
- Jan 2026: 98.7% (Finnrick)
- Feb 2026: 98.8% (Janoshik)
- Mar 2026: 99.2% (Finnrick)
Remarkably consistent. The highest I've seen from any compounder. For reference, pharmaceutical-grade semaglutide API is typically 99.0-99.5% pure, so these numbers suggest they're using high-quality raw material.
I also want to note that CompoundPharm provides their own in-house COA with each order — but I still recommend independent testing. Trust but verify.
