I ran it a little different last time, i ran 100mg ed starting about 5 days before my last shot of prop, and continued with 100mg until morning wood returned constantly. Then down to 50mg ed for a few more weeks. This was after a 15-16 week cycle and i think it worked better than the standard dosing, but it is hard to say because so many factors were different. I normally have used the normal dosing schedule explained above, just thought i would share.
