Through highschool I never ever considered steroids. I trained, ate, and slept great and I was by far the most built guy in school, and the strongest. There was this guy in my grade who wanted to be just like me so he took dbol tabs. He gained about 15lbs but was still much smaller and weaker than I. It was then christmass holidays so there was no school for 3 weeks. When we all came back to school 3 weeks later, I gained about 3 lbs by eating and training naturally, but the guy on steroids came back about 20lbs lighter because he was not ready for steroids. He did not know how to eat, and train correctly, and couldnt keep eating and training with the same intensity for very long, because training 5-6 days a week, eating 5-6 meals a day was getting to him.
You have to become a bodybuilder before taking steroids, because when your done your cycle, you wont keep anything because it takes alot of dedication to keep what you gained. When you lose your gains, people will notice, and they will think you are sick and dying or something, trust me, I have seen it and it is funny.
My advice is, wait until you have trained for at LEAST 5 SOLID years before using. And do a real cycle, not this shitty dbol only crap that kids do.
