I never got the spontaneous erections.....but i was always horny....could've been from testosterone also. The only reason i stopped taking it was becuz I started to get little freckles or brown dots on my face. i didnt mind them on my body but once they started popping up on my face, i didnt like that. I have heard if you keep taking mt2 that they go away or blend in....idk. in the two weeks time, i tanned outside 1 time cutting the grass. I got bronzed nicely. My lips got a little darker but not really noticable....that went away now, however i am still a bit dark. I was running 1.4mg ED
