I know they say there are no stupid questions, so I'll just say that this might be strange. I'm about six weeks into a winni/sust cycle now. I'm doing 50mg winni EOD and 125 mg sust EOD. I know that the sust is a little low, but I have to make sure I don't get too big too fast because I will be tested if I am suspected for AS use. Even with a low dosage of sust, I've managed to put on about 12 lbs in the last six weeks. I'm working a little more cardio now and pulling a lot of fat out mf my diet to be slow down the growth a little. Anyway, here's my question... This morning a noticed a small "bump" forming under my skin on the side of my chest; just in front of my armpit if my arm is down. The sust doseage is very low and I've noticed no swelling or over-sensative nipples so I think gyno is out. The bump is maybe a half inch around and I guess it's more of a knot. It's gotten a little larger since this morning so I'm starting to get concerned. Going to a doc is the last option because of my job, so I figured I'd ask the real experts out there. Anyone out there heard of anything like this??? Thanks.
