If I knew then what I know now, I wouldn't have ever started. At the time, I was so curious and full of delusions, I thought I could make a living as a bodybuilder. LOL!!!
Still, I would have wondered "What if...?" for the rest of my life if I hadn't tried them, so it was probably inevitable. I did have fun, and I did learn a lot about myself while taking them. Considering I managed to escape sans significant side effects, I guess I'll chalk it up to a "learning experience".
If you like to lift and you've been curious for some time, give 'em a try.
