Understand this: the more fat you have, the more aromatase enzymes you have. Aromatase is the enzyme that converts androgens (like test) to estrogen.
So by using AAS when overweight, you will see increased estrogenic side effects (including hypertension) and a good chance of gyno.
And if you're planning on doing a bulking cycle, you're only going to get fatter.
Your best bet is to cut down naturally to 10-12% BF, then use AAS to bulk.
