I preffer Humulin-R over Homolog or any other, i feel humolog is to fast acting and will not give a full benifit as humulin-R would...kisks in within 15min peaks at 2 hours and hangs around for about 6 hours total...i like to time mine that it peaks about 15 minutes after training...but that can be tricky as you need to bring some carbs with you while training, i bring Crea-Fuse...10gm of creatine & Simple sugar mix...any kind of that sort of a drink will do...Good luck...XXL
