I seemed to have gotten a lump under right nipple from SARM S4. I took if for about a month and a half last spring and the vision problems were crazy. I would see a light at night and it would have a very very yellowish hue. It did seem to make me more vascular and bulkier but it also aggravated the hell out of my very minor gyno I had from prior roid use. letro didnt do anything and I was on that for about 2 months. Its weird and kinda nasty but when I squeeze the lump, s$%^ starts coming out of my nipple ... Prami, which I intended to use for gyno, didnt work, but it is AWESOME for leaning out and mood and dreams (and I SWEAR I get more girls with it. really weird...)... I cant seem to get rid of gyno. i am in the process of starting surgery for it, but as a last resort i just started exemestane/nolv/Clomid combo. Trying all angles. Exemestane apparently works a different way then letro (type I vs type II) so I am going to try it. Let me know if anyone has had any success with this or maybe in the same situation.
