ye mate 75 should be fine depending on your size i think, im not a big build and i ran 50mg per day, milk thisle is a must it cost like £3.00 for 90caps so is so cheap and will help out, as for joints i suffered very badly with tennis elbow i mean extreme, if i made a sharpe movment with my arm it would be sore till the next mourning. remember if u decide to do the injectable version it can be drunk. \ hope it helps
