Juicing so young teaches guys to rely on the drugs, not training and diet which will fuck them in the long run. Over my 20+ yrs in the gym I can count on one hand how many guys under the age of 19 that actually knew how to eat and train (sort of)and possessed the discipline to follow through with it.
I know that if I was a teen and I wanted to consume 200 grams of protien a day my parents would've never allowed it because they would've gone broke feeding me. So even if I wanted to do it right I wouldn't have been able to.
Also relying on your bros to keep you in check is like the blind leading the blind. Keep in mind I'm not one of your lard ass coaches still trying to relive his glory days. I'm mid 30's, one of the biggest/strongest guys in my state, and people still ask me if I compete all of the time. So I'm not some washed up, beer bellied , alcoholic, has been telling you to do as I say and not as I do. By using roids at such a young age you're selling your genetic potential short. And if you're using college as an excuse, you might wanna think about this. A college education is great. However it's no guarantee of success in life. 20-30 yrs ago it may have been different, but these days having a BS is nothing special. Sure, you could go to school another 4 yrs and become a Dr or Lawyer, but when you graduate you'll have a monthly student loan payment that rivals a monthly home mortgage in amount. You'll also probably work 60-80 hrs a week at your own practice-leaving little time for dieting/training. If you get married/have kids you'll have even less time. This kind of lifestyle will age you quickly, and once you no longer have your youth you may truly wonder why you chose the path in life that you did-and by then it will be too late to change it. So before you make irreversible decisions about using AAS so young, try to see the big picture. What do you want your day to day life as an adult to be like? If you wanna join the rat race and die of a stress/diet related heart attack at age 45 go for it. Success to me is measured by comfort, health, and happiness, not how much frivolus material shit you have or how much $$$ is in your bank account. Why have all of these nice things if you never have time to enjoy them? It's not like you can take these things with you when you die.
