IGF and tired?

Is it just me or anyone else get tired when starting the Imense growth
factor? I just started and dam I seem more tired at night. Was going
to hit the gym last night but just couldn't get the energy. Could be all
the other shit I got going on. Work, coaching ect. Anyone else experience
this or is it just me, or mabey just cus I started it might pass.

I feel that also. I thought I was just lazy.

guess i got lucky for once and dont get tired from it , i do only use 20mcg also.

It's called hypoglycemia, low blood sugar.
