I think that any adult can make up his mind regarding this.
However, since you would like advice:
As others have recommended, I feel that gaining experience is extremely helpful before adding in the variable of AAS.
While experience cannot be directly attributed to temporal parameters (i.e. many people who have years in the gym still have no idea what they are doing or how to improve), I do feel that experience is well correlated to such parameters.
If you train intelligently, constantly assessing the variables at play in relation to your current level of progress, and changing certain variables to see how your body reacts and what works best for you, you will understand a great deal that will deeply benefit you throughout your training.
If, however, you add in the variable of AAS BEFORE you have an understanding of all other variables, it may well be (and this is true for many people I know), you will never understand your bodies reactions well, and use AAS as somewhat of a crutch rather than a support and asset to the rest of your training, diet, etc.
When making hard, even slow progress, and having to own up to a shitty diet slowing your progress, or poor sleep patterns, or few stress management skills, it forces you to deal with these issues in order to resume progress. You have a greater opportunity to perfect many aspects of training.
But, to reiterate BONEZ suggestion: You’re an adult. AAS is a personal decision. Do whatever you want.
