Hey. This might be a long shot since you have last log-in in Nov 27, 2014 but maybe this gets to your email...
I came across your post about low testosterone, acne, and very oily skin (after tretinoin cream). I have the exact symptoms as you did; I am 24 year old male right now. My testosterone level was around 308 ng/dl,
I am in the process to figuring out the cause of all this...trying to get my testosterone back up because this low libido stuff is not fun at all...
Anyways, were you able to figure out the reason for those issues? Any help would be greatly appreciated! Just want to finally end this long battle with acne.
