steroids should only, be used by healthy adult males with no pre existing medical conditions.
if you are unsure about your lipid profile, and sure you want to take steroids, then yes, of course you should get blood work done to see the shape your in before using aas.
if you are even slightly out of what are considered "normal healthy" ranges, then you should not take steroids, and work on getting healthy first.
this what I would guess most people who make threads like "heart pounding on sd" or "high bp on cycle" do not do before jumping head first into an aas cycle. so hats off to you for asking first.
