The original post is correct when he said the higher your bf the more Test will be aromatized into E2. The aromatase enzyme is stored in our body fat and where it also carries out its action. So the more bf we have the more aromatase enzyme is present.
It is possible to keep your E2 in check while on cycle using certain mandatory meds. But it's still not a good idea if the rest of your body is under metabolic stress from high cholesterol and insulin resistance from ooor diet.
I'm not saying you're a complete slob lol I'm sure you're in quite good health. But I would heed the advice of these posts and get a good 6 months of training under your belt steroid free. Build up a significant base of strength and re-evaluate the steroid use. By then you should be around 12-14% bf and in much better condition to handle the potential stress of gear usage.
Hope this helps,
