Before asking your stupid beginner questions, make sure to read:https://www.reddit.com/r/steroids/wiki
Yes it's reddit, find a better compilation of information about steroids on the internet if you don't like it.
Also, include:>e-stats>age>time spent lifting>height>weight>BF%
Oral only cycles are retarded and you're a retard for considering them.
We can't help you dose your AI, it's different for everybody and there's a lot of factors at play. Figure it out yourself.
And most importantly,
NO SOURCE TALK (This isn't up for debate, you will be banned). Figure out where to get steroids on your own.
