i started at 17, i used dbol mostly and then graduated to fina pellets around age 18....i had great results, i was the most muscular kid in school, popular, had parties all the time with the ladies....then it was time for some Omna's which was my first injection cycle. i loved it and i havnt gone back to orals since then.....but now im 25 through college and law school and am a practicing attorney so i only cycle 1 to 2 times a year to keep that lean sexy look.......do i regret it? hell no, but i had a personal trainer who was on flex magazine's cover for over all winner and he told me everthing i needed to know........moral of the story.......RESEARCH (i think, or whatever)
