I waited until I was 25 to start using. In highschool and college I was under the impression that I was a better person for not using steroids while my friends were. What a load of crap. Since I got into the anabolic supplement game I have become much more knowledgeable about diet and training. I credit this to wanting to make the most out of every cycle. I only wish I had started earlier. I'm 28 now and have 3 cycles under my belt and getting ready to start #4. I usually do at least one every year.
