I had gyno surgery in January 06.
Had about 10oz of hardened tissue removed from the left side of my chest where the problem was. The right side was fine and only required a small bit of liposuction to even things up a bit. If you've got it and it bothers you, have the surgery - I was under the knife for about three or four hours and was in hospital for 24 hours recovering. No problems.
I should point out it wasn't caused by gear use though - I'd had it since I was about 12 and training and gaining weight had just made it worse at a time when my hormones were all over the place. It looks fine now and there's a scar around my nipple area but it's barely noticeable.
10oz of tissue and a 4 hour surgery and an overnight stay!
Holy fuck, you did not have gyno-you have a full grown tittie!
But if you had it since you were 12 that is full on genetic gyno. I have seen some of these surgeries where the amount of tissue removed form 15, 26, 17 year old boys could fill a milk container-I am talking baseball sized fiberous type gyno tissue. Felt sorry as fuck for those kids.
Glad you had it removed-I hope you had some sort of health insurance-I dont have shit and the surgery you had would be $10K plus easy.
