I was on Testogel for a couple of years and I made some posts here about my experiences with it.
I was on 50mg a day and I felt that somehow I absorbed it too quickly, i.e. I would get a rush about 4 hours after application, then deflate so to speak as the day went on.
I recently saw my endo, and after some ridiculous conversations, he eventually put me on Tostran.
I have been on it about 3 weeks now (60mg - the standard dose) and I feel much better !
The downside is it does not dry nearly as fast as testogel - takes at least half an hour wherea testogel was more or less instant. But I feel much better throughout the day (and night). To put it bluntly, I can get erect at night times now whereas on testogel it was hit and miss.
I read somewhere that adding aloe vera from the chemists / supermarket makes it dry quicker.
To be honest if that works I would say its the best gel.
However, its apparent that everyone metabolises these gels differently and what may be good for me may not be for others.
