Is PX1's Bronchogen made in the USA?

Yes. Bronchogen is manufactured in cGMP-certified facilities in the United States — never imported. Every lot is manufactured, purity-tested and packaged domestically.

How do I verify the purity and COA for Bronchogen?

Each batch ships with a lot-specific Certificate of Analysis showing 99%+ HPLC purity, mass-spec identity confirmation and endotoxin results. The current batch's report is published on this page and matches the exact vial you receive.

How is Bronchogen shipped and stored?

Lyophilized vials are shipped domestically and are stable at room temperature for transit. For long-term storage keep vials cold; once reconstituted, refrigerate at 2–8°C and use within about 30 days.

Is Bronchogen for human use?

No. All PX1 Research compounds are sold strictly for in-vitro laboratory and research use only — not for human or animal consumption, and not for diagnostic or therapeutic use.
