PBN Site: "Caffeine has not shown any benefit on power and strength."
(And I think a cup of espresso actually has less caffeine than a cup of coffee.)
Just goes to show you that there aren't any perfect studies out there yet. There are always limitations that either cannot be controlled for or are disregarded in a particular study. Because of this, the use of caffeine has to be evaluated on an individual basis and we cannot make any blanket statements regarding its use at this time.
