Question on beginning

I am a 19 yr old lifter who has done prohormone cycles, and a mild sarm cycle (osta ibuta enclo) and i have seen the good, the awesome, and the worst. Everyone always says screw the mild stuff that can make you have horrible sides and just do test. I have a strict diet, good split, and my job doesn’t restrict my lifting habits. I don’t drink or do drugs like weed and whatnot. I simply want to know what the smart thing would be to do if i were to start a cycle. I’m doing research on the diff types like test e and c and so far i’ve seen just a 200mg test cycle could do me the justice i want. However i’m worried about the longevity and i don’t wanna be infertile. I also don’t wanna have to be on test the rest of my life if i can just rip cialis or tadalifil. Honestly i have a really great amount of knowledge in prohormones, lifting, and sarms. So all in all id really appreciate if someone told me what this is all about, considering i may not even get into this if it’s eye opening enough.

Another thing, my test may already be a little screwed due to past cycles, and im actually working on lowering prolactin right now due to 19-NOR-DHEA.
