Hydroxyprogesterone heptanoate

Hydroxyprogesterone heptanoate (brand names H.O.P., Lutogil A.P., Lutogyl A.P.), or 17α-hydroxyprogesterone heptanoate, also known as hydroxyprogesterone enanthate, is a steroidal progestin of the 17α-hydroxyprogesterone group that was developed by Roussel and Théramex and has been used clinically in France and Monaco. It was a component of the experimental preparation Trophoboline (or Trophobolene), which also contained nandrolone decanoate and estrapronicate. It was also studied or used in Tocogestan, a combination of hydroxyprogesterone heptanoate (200 mg), progesterone (50 mg), and tocopherol (250 mg) oil for intramuscular injection.
