  1. The timing of this podcast could not be more ideal for me. Crazy. This is an area of hypertrophy research where good studies are lacking and it seems like there is pretty significant inter-individual variability. Thank you

  2. You’ve fallen so far Ben. from a big time name, to a certified snake oil salesmen. Just because the majority of the population is ignorant doesn’t mean it’s alright to take advantage of them lol
