I'm just at the beginning of an experiment applying DHEA to my scrotum, partly for assessing if it will increase DHT and free T. Oral has always caused mood problems and worsens my sleep, which has been garbage for years due to bipolar illness, but my DHEA-S has been on the low side for years. Last measurement was 178 mcg/dL. Been on and off T injections for over 10 years, various protocols/doses, cream & pellets. Labs always look good but never experienced mental or sexual improvements. Gained muscle but also gained weight & fat(or water) around my mid section and the only time it disappears is when I go off of T.
As for how I do this, I empty the contents of a 25 mg capsule into my palm, add a few drops of olive oil, mix it with my finger, then massage it into my scrotum. Libido/sexual thoughts more prevalent. Still getting my late evening erection and now, sporadic nocturnal erections and a now and then mid afternoon erection. No morning wood, but my penis is stirring, LOL. Penis hangs longer and fuller. At some point, I'm considering increasing the dose to 1 1/2 capsules/37.5 mg.
I tried 25 mg 2X (morning/evening). The morning dose seemed to slow down my body, similar to jet lag. Maybe it lowered my cortisol too much. I'll get labs in June or July.
