No doubt 7 pounds a month can be gained but I must ask what quality of weight? I dont care who you are, what your genetic make up is, or how much gear you take, 7 pounds a month of weight gain cannot be lean muscle mass or be good for you.
I must ask what is the fascination with the number 310? I am not bashing just asking. Because I never understood the want to gain so much weight, not be able to tie your shoes without breathing heavy and generally look and feel like shit.
