Dylan is right. I'm running it right now, 60mg/day. I wouldn't recommend a dose lower than 40 by itself. If you have virgin receptors 40 would probably be fine. As far as sides the only thing I'm feeling are slightly dryer joints.
You should put as much into PCT as is necessary. I'm going to use HCGenerate last two weeks & through PCT, a light dose of clomid and a natty test booster. I've got forma and a grab bag full of other ancillaries just in case. You'll learn either the hard way or the easy way that you should have more than what you think you'll need for PCT.
Good luck
