I have some Bold 200, I weigh 215, 6'1" tall and about 16% BF, ive been lifting for about 6 years off and on. I have been tol about 600mg/wk would be good, and it is good to use by itself. I have allready made sure its reall and it is so if you have any advice for me let me know this is my first reall cycle ive taken sustinol 250 before about a year and half ago but didnt take enough for a full cycle.
