IGF scheduling

I will be on a 15 weeks comp prep cycle soon. Is it better to use IGF during the first half of the cycle or the last weeks of the cycle. OR can I do first 4 weeks, rest 4 weeks and then use IGF again during last 4 weeks of cycle?

i would do the first 4 rest four next 4 method

the research indicates that IGF becomes ineffective after 30 days of use.

4 on 4 off
