Note that "Progynon-Depot" by Schering, Germany is estradiol valerate, but "Progynon-Depot 100" by the very same company is an entirely different substance, estradiol undecylate. Estradiol undecylate has a longer chain length than estradiol valerate; its action is therefore prolonged, and smaller dosages are probably appropriate. The author does not have enough information to make any other comments about estradiol undecylate except that it will reportedly go out of production soon due to the side effect of "excessive feminization" for its only labeled usage, prostate cancer.

If you are allergic to any nut oil, be sure to ask your pharmacist about the base, especially for the generic form of this drug. Castor oil is most often employed, which few people are sensitive to, but a few pharmacies employ other oils such as sesame, because it is less viscous and easier to run through their equipment.
