Great physique particularly for how little PEDs you've used. Upper body and quads look really good. Back looks a bit small in comparison to the rest.
As someone new to this here are the two most important things to learn. First, take care of your health - blood pressure, blood sugar, liver, etc. Your monthly prescription / health supplement bill should greatly exceed your monthly PED bill.
Second is an analogy Dave Tate gave years ago. Steroids are your ace card - you can only pull them out once. If you use them to be a good high school football player then you probably won't make it in college. If you use them to be a good player in college then you probably won't make it in the NFL. If you use them to be a good NFL player and get a few more years + a few more million dollars then you did it the right way.
When and how you use them is a personal choice for each individual to make. For you, you have genetics on your side more than most guys, meaning you don't need as much of the PEDs to get similar results. Add stuff in as needed, escalate the doses as needed to keep making progress. Don't go for 2,000mg total on your first prep cycle just because you read guys doing it. You definitely have the ability to turn pro and go at that level for a good while if you take it slowly.
@mytreefiddy was still competing as a men's physique pro into his 50s I believe.
