Polydiethylstilbestrol phosphate (PSP, PDSP) is an estrogen medication which has been used in scientific research and has been studied for use in veterinary medicine as a livestock growth promoter.[1][2][3][4][5][6] It is a phosphate ester of diethylstilbestrol (DES) in the form of a polymer and is a polymeric form of fosfestrol (diethylstilbestrol diphosphate); PDSP acts as a long-lasting prodrug of DES.[1] It has similarities to polyestradiol phosphate and polyestriol phosphate.[1]
