Method
On November 8, 2026 the publisher reviewed public pages on each manufacturer's own site. We compared the launch route, any stated minimum and its unit, formulation, filling and testing support, packaging, and scale-up handoffs. The order reflects fit for the stated buyer, not a numeric score.
Limits
This is desk research. Nobody visited a factory, ordered a sample or checked a certificate registry. Company statements are not independent verification, so each profile ends with items to confirm in writing. Nothing here is medical, legal or regulatory advice.
