So in the past ive only really used some lean muscle mass protien and some weight gain protien since ive started which id say is about 6 months ago ive put on 5 kg to my 60 kg mass which is rather slow but i have the gayest metabolism so i gota deal with it and i think there mite be a chance that i have a inborn metabolic disease because the length of my arms is 6.5ft and the length of my body from feet to head is 6.2 feet coz my doctor told me to check it and he sead i mite have one of those conditions so any ways what i wana know is the list of supplemts i should have and use...fish oil and some form of protien powder but what els ? is there any supplements you can point out for some one with super fast metabolism ?
