The trimix gel is an off shoot of Muse (alprostadil).  The Muse is available, but because it causes pain problems in many guys the trimix was developed.  I have not seen it packaged , but the contents are the same as the trimix injections. I am guessing that it does not require FDA approval as the contents are already approved. 

welcome to the zero club Dirtmover, it is a nice club to be a member of. Can't say much about the ED, I have been impotent for 18 months.

peace to you

Great news on the zero results. Welcome to the club. The difference between trimix injections and trimix gel is the first is inserted into the cavernous cavities of the penis, the second is absorbed thru the body from inside the urethea. You'll probably find a big difference in time and response between the 2. Trimix gel has been around for several years, but no one was compounding it during that time, until recently when a company started doing it.

GREAT! I hope you will always be in the zero club. you've been a lot of help for me. I am 20 days before you on surgery!!

Congratulations on your beautiful zeros!!
