What's up people? I'm new to all this but I just have a question about the NPP that I'm about to start. I have been taking Test C for about a week now and come Monday ima start with NPP. Here is the schedule that I came up with. Monday, Wednesday, Friday - NPP 100mg a week Tuesday, Friday - Test C 250mg a week I'm trying to figure if the npp is going to mess with my sex drive or are there going to be any side effects that I need to know about before I start.
