20α-Dihydrotrengestone (20α-DHTG ), also known as 20α-hydroxytrengestone , as well as 6-chloro-20(S )-hydroxy-9β,10α-pregna-1,4,6-trien-3-one , is a progestin and the major active metabolite of trengestone .[ 1] [ 2] prodrug of 20α-DHTG, as it is largely transformed into this metabolite when given orally in humans.[ 2] [ 1] potent progestogenic activity similarly to trengestone.[ 1]
