I recently saw my urologist because pills were no longer working. He sent a script to a local compounding pharmacy for Prostaglandin E1 20mcg/ml. I have tried all kinds of doses over the past 3 months without much luck. Erections have been mediocre at best. Last night I injected 1ml and still barely had enough erection for sex. I have read about other mixes that include more than just prostaglandin such as trimix and quadmix. Should I move on to those mixes since this alone is not working? Very discouraged at this point. Thanks for any advice.
