Over the years, I have known men who have used low-dose DES (Diethylstilbestrol) with some success. DES has been discussed here in a few threads.
Wikipedia [1]:
"DES {was a} standard initial treatment for symptomatic advanced prostate cancer for over 40 years, until the GnRH agonist leuprorelin {Lupron} was found to have efficacy similar to DES without estrogenic effects and was approved in 1985."
"It is still available from compounding pharmacies ..."
Apparently, that is no longer true. A pharmacist told me that he could no longer get the powder, & couldn't work on a prescription for human consumption if he had the powder. He wished he could get the powder to satisfy the demand from dog owners:
"DES has been very successful in treating female canine incontinence stemming from poor sphincter control."
Strange that it is now banned in the U.S., considering recent interest in using 1 mg doses for CRPC cases.
