Tofacitinib citrate API is a pharmaceutical-grade chemical and is typically sourced through GMP-certified API manufacturers or distributors. If you’re looking for legitimate suppliers, here are common avenues and some well-known companies that often stock tofacitinib citrate as an API or in related forms. Availability can vary by region and over time, so it’s best to contact the suppliers’ API sales teams directly.
