if this is your first cycle its not safe to run the cycle longer then 15 weeks imo because u dont know how u will recover after it , if it isnt , i would run it for 20 weeks . what i would suggest is up the dose to 500-600mg and just run what u have till its done . also USE THE ADEX dont just have it on hand , use it to PREVENT sides not take care of them when u get them , controlling estrogen is important and not just about the sides u can see . if all u have is clomid , run in at 100/100/50/50/ 2 weeks after your last injection
