I don't think you need to be running more than 50mg per day. It just tends to add more sides that are not worth the little extra progress you might see.
The best way to get leaner fast is going to be fasting and changing up diet. Focus on that #1. I would also recommend Cardarine. Don't bother with any SARMs because you don't want to go on vacation being on a PCT.
I like anavar for cutting and would add Cardarine to the stack. Keep the var to 8 weeks or less though. You can continue the Cardarine for much longer though. I recommend 16 weeks before taking 4 weeks off minimum.
