I take mine usually 12 hours apart. Half in the morning and half in the evening. Also, 40-50mg will be fine if this is your first cycle. My first cycle was a winny only cycle and I did 50mg for 6 weeks and it was a good one. I know most here will ridicule for taking an only only cycle your first time around but many people here also went that route. We were all newbies at one time or another.
Good luck and head to the other forums and post your training schedule and results. It helps to keep a log to keep you on track and focused.
