I read this on Poliquin’s Facebook fan page:
“I get asked this a lot, what do you think about using supplements to raise insulin before training? My take: you need cortisol to have energy during the workout, so that you can use heavy loads to create overload. Since raising insulin lowers cortisol, it does not make much sense. Another case of looking at the World through a straw!”
I’ve always spiked insulin preworkout, what do you guys think?
