Has anyone tried navel transdermal testosterone application? This study Navel absorption: transdermal bioavailability of testosterone shows bioavailability of 79.9% compared to 49.9% forearm administration.
Yes, I've tried scrotal testosterone dissolved in 10% DMSO and worked very well but caused testicular pain so I had to stop.I’m sure the concentration of nearby veins in that area helps. Are you familiar with applying a transdermal T (cream) to the scrotum? I don’t have the paper in from of me, but it states a near 8x increase in testosterone bioavailability for absorption in scrotum application vs abdominal application.
