Igf-1 LR3 + PEG MGF

I’m entering week 2 of an IGF-1 LR3 50 mcg pre workout 4 week cycle. I have PEG MGF on hand and I plan on using it on weekends and off days only. The consensus seems to be doses of 200mcg. Because I will be researching it on off days, should I just pin it Subq? Or still bilateral IM in the last body part I trained? Thanks
