I take DHEA as well until I can get on T (which will be at minimum 4-6 months from now, possibly up to a year) and people can debate about whether or not it turns into T or E in an FTM but well documented side effects in women are lowered voice, hirsuitism (increased and darkened facial and body hair) and male pattern baldness...which as I understand are all very directly related to DHT levels.
Since we can't talk about dosage I'll just say I take more than the usual level recommended to cisgender women to attempt to get those desired side-effects, but considerably lower than the upper limit of what is considered a dangerous level.
I also lift heavy and take creatine, which might also increase DHT (
http://www.ncbi.nlm.nih.gov/pubmed/19741313 ) but definitely helps me lift heavier.
I'm not really expecting miracles, I just wanted to do something that would possibly make me feel better, or at least like I was doing some little thing towards transitioning more. I started on DHEA one month ago yesterday, and besides the improved energy and sex drive (though that could be the weight lifting, or everything combined) I've noticed the hair on my upper lips is starting to get darker. They're still pretty fine but there's a bunch of them that are definitely growing in brown.
I figure DHEA is pretty safe as a supplement for most people, since it's been around almost 50 years now and it's still OTC.
Ryuu, what Estrogen blocker were you planning on getting?
