I've written about the use of half and half and raw eggs. It's great for bulking. I've used raw eggs in shakes and never had a problem but in case there is a problem, it's one you don;t want to have!
I've told a few guys to mix BIG BLAST with half and half and ice cream and they think it's crazy but if you're really underweight you'll fill out fast and it taste friggin amazing. Still, fats post WO are not optimal.
I also said the Isopure was good, but that's zero carbs. I mix the Alpine Punch with 1/4 cranberry juice and that's delicious. But once again, fruit juice doesn;t spike insulin which is what you want (maybe the only time you want it) post workout.
Incidentally, that's actually a good time to take vanadyl sulfate. A dated supplement but it will increase glucose deposit. Anyway, it's cheap as hell and a lot safer than using insulin!
