I have read several threads on here that stated that overweight people shouldn't use steroids because of increased likelihood of certain side effects. I would like to know why an overweight person would be more likely to develop gyno or high blood pressure than someone with low body fat. I haven't seen any links to any studies in any of the other threads so I was wondering if this is opinion based on anecdotal evidence or is there science to back it up? Does the increased likelihood of gyno and high bp only apply to sedentary people or would someone who works out and does cardio everyday still be at increased risk?
