Well since the PEG version of MGF is supposed to stay active for a few days, I dont think it's imperative that it be taken pwo like the regular MGF. Also who know at what serum ammount of PEG MGF and for what duration after taking PEG MGF that inhibition of differientation occurs. So I just take the IGF ED or almost ED. Worse case scenario the IGF taken the day of PEG MGF will not do anything because of inhibition caused by the initial MGF level spike.
If you dont want to waste IGF you could take your IGF every day except the two days per week you take your PEG MGF.
As far as your slin goes, if it were me Id just take the slin pwo like I ussually do irregardless of weather it was an MGF or IGF day. Or for a more extreme bulker taking slin in the mornings ED in addition to the PWO slin dose. The LR3IGF should be active for pretty much all day so theres no rule that says you have to take it post wkout if hypoglycemia is a concern. Personally I've never had any problem taking my LR3 IGF and slin at the same time PWO. (because thats when it was convenient for me to take the IGF.) But if your blood sugar is gettin low and and your feeling dizzy and crappy, then just seperate your slin and IGF doses by a couple hours and you should be golden. Hope I've been of some help.
