I think everyone's confused on this one. He's talking about 50mg of clomid, not m1t. I hope at least...
I assume your running a 2on/2off/2on cycle?
You should stick to your original plan of 10mg m1t for 2 weeks. The take clomid during the 2 weeks off. Most use nolva, but these dosages should be about right: 200mg for days 1-3, 100mg for days 4-7, 50mg for 8-14. Then take m1t for 2 more weeks followed by 3 weeks of clomid. 200mg ED for a week, 100mg ED for a week, 50mg ED for a week.
