To echo the advice above, be sure you have your diet nailed and consistent before crossing over to the dark side. Steroids can do a great job at masking a poor diet, but you simply won’t get the best from them unless your diet is nailed - and if it really truly is then a sensible cycle, even a simple one at low to moderate doses will yield far better results than a high dose or multiple compound cycle with a poor diet. To me that’s the thing you need to nail, and is more important than starting body fat- recomping on steroids with a good diet in place is just a different world compared to trying to recomp naturally and, IMO, is probably their best use for most first time users.
As for what to take first cycle- testosterone, either E or C. If you plan on doing more than one cycle as time goes on then it’s inevitable that you’ll start stacking compounds at some point but testosterone, whether high or low doses, should always be in the mix as a base, and you really want to figure out how you respond to it in regards to gains and side effects before adding anything on top of it.
As for starting with an oral only cycle like dbol or var, well you could and I do understand the hesitancy to pin, but orals tend to be pretty inconsistently dosed and come with a range of side effects, some of which are kinda silent like tanked HDL levels (most orals are horrible for this) and liver stress. And of course orals will suppress your natural T levels so you’ll still need to PCT and deal with all the issues that can come from this including fluctuations in estrogens which can be a big problem even in orals that don’t aromatize (the drop in T can do enough damage to your T/E ratio even without raising E). Most first timers think orals only are going to be low risk but not so at all IMO.
