Hello everybody, I have been searching for an answer to this question and I can't seem to find any answers for my particular situation. Here it goes......Me and my brother started lifting around the same time, it's been about a year and a half and he is HUGE!!! Know I have gained alittle, but nothing even remotely close to him. And to top it off I follow strict diets (3,000 cals) 300 grams of protein good carbs, good fats, creatine, multi vitamins.....ect..... and he eats shit, Burger Kind, Mc Donalds...and doesn’t gain an ounce of fat....all muscle. What I am wondering is if the fact that he more closely resembles my father, who is a good sized guy, and I look more like my mother, who’s family is not the most muscular (to be nice). Could it be possible that I have a higher estrogen count and that could be hindering my gains? and if so could I use a product like 6-oxo even if I am not using anything like a PH. Thanks for any help you can give..
