I wanted to see what’s considered a good trough level with topical gels and creams 24 hours after application. I’ve seen several guys over the years state their trough levels are only in the 300ng range. Then drugs like Androgel and testim say to get trough level between 350-750ng 24 hours post application. It seems it would be difficult to have a trough much above 300-400ng considering the rapid half life of topicals. I realize most doctors want a level 2-6 hours after application, but it would be nice to know. Anyone that has been on topicals long term please chime in.
