i was on a cycle of dianobol and sustanon 250 for about 12 weeks and had massive strength and wieght gains but started to notice the sighns of gyno and had a little lump in my nipples so i stopped. all sighns of this have gone now and i have waited for a year just to be sure. i want to start a new cycle now but am worried of this happening again can any one give me any advice?
