Desogestrel

Desogestrel is a third-generation progestogen with high progestational selectivity and minimal androgenic activity, used in combined oral contraceptives and in progestogen-only pills at higher doses that inhibit ovulation. Simson Pharma's Desogestrel reference standard and impurities support stability-indicating testing for this widely prescribed contraceptive progestogen.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Desogestrel Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
