I have a couple questions for you guys. I recently had a blood test where my TSH and antibodies were quite high = hypothyroid. I used to be a little bigger (195) but lost a lot of weight to 155 and now am 175, during part of a period I took Tyrotabs. I usually have a sporadic sleep pattern due to college and such. I usually stick to a relatively low carb high protein diet. So some questions: Do you think this could be because of my diet, me losing a lot of weight or the thyrotabs? And then what would the effects of having a hypothyroid have on weightlifting? Would this also mean (and I'm pretty sure it does) that I will be unable to take prohormones and the like? Thanks guys and I appreciate all the responses.
