I wouldnt be surpised if Partlow wouldnt even tell Aceto what he was taking...because imo in pro bbing "fast metabolism" = more fatloss drugs.
Some guys, pro's and non pro's really do have beyond ridiculous fast metabolisms....they are rare, very rare but they exist. IMO if these guys can learn how to eat they make the best BB.
I'm not discounting the drugs, but I think sometimes the drug aspect has started to largely overshadow everything else.
