It is an interesting listen for sure. The message I get, whether correct or not, is that there is not much that reliably helps you make gains other than consistent hard work, creatine, and protein if you are deficient. I have tried all sorts of supplements over the years with variable expectations. Having that money back sure would be nice.
Love me some Dr Mike. I've managed to cut out all the bs in my supplement routine, I used to powerlift competitive when I was 17-21 and wasted so much money on random crap. Now its a stack of multivitamins, whey isolate, creatine mono and cranberry juice.
