There are several important factors users should take into account before beginning to use anabolic steroids:

Age: Are you physically and mentally mature enough to use AAS

At a young age the human body is getting used to the new hormone levels. This makes it hard to make balanced decisions. Irrational use of AAS it might send your brain over the edge. Remember you run a risk of having to take shots for the rest of your life by starting AAS. Consult with experienced and older AAS users before starting using it. Get informed, learn for other users mistake and not from yours.

Body fat: Check is your body fat level is low enough

If your body fat is high you have a higher chance of being affected by side effects. High body fat also means you are out of shape and should take care of that naturally.
Diet. Without a good diet you do not give your muscles the fuel they need to grow.
You need to eat protein at least every 3 hours. AAS isn’t a diet plan. If you want to lose weight then eat right.

Work out Plan: Set a training plan while using AAS

If you take AAS to early then you run the risk of screwing your body up. If a good work out plan isn’t followed on a cycle you waste the cycle. Make sure you have a good plan and have been on it for a long time.
