i have an over-active thyroid and i was wondering if that could impare my ability to gain from PE. i have worked out and my muscles take almost a week for the soarness to go away and the whole point of working out and PE is damaging and repairing cells for new growth but if it takes my muscles almost a week to heal how long is it taking my dick to heal i kno not to many people in here are doctors but could it be possible that an overactive thyroid which by the way is responsible for so many hormones in our body can keep me from gaining?
