Broscience is the predominant brand of reasoning in bodybuilding circles where the anecdotal reports of jacked dudes are considered more credible than scientific research.
Broscience in action:

"Bro, you gotta slam 40-60 grams of waxy maize plus 20 grams of BCAA within 7 seconds of finishing your last set of squat rack curls. Otherwise, you'll go straight catabolic."

when guys weight lift and talk about muscle growth without actually knowing the science.
That guy is swole.

Why?

Because he uses maxX 4 times day.

Sounds like bro science.

"scientific evidence" that is culled from magazine advertisements for various bodybuilding supplements and stated as implicit fact within bodybuilding user forums; typically prefaced with the word "bro" or shared with the "bros."
Broscience in action: ok... So I heard to take my SizeOn over a periode of time while working out.... sounds like sound advice... or does it? I have read that Creatine turns toxic after about 3-7 sec. after and depending what kind of medium its mixed in .... so why dosnt this apply to SizeOn... I havent read anywhere that it is PH balanced like the Kreacline or what ever its called.

A body of knowledge regarding men's health substantially lacking in scientific rigor.
Broscience ranks below Jewish physics and above climate science in terms of scientific rigor.

Word of mouth knowledge passed off as fact, primarily among bodybuilders + weightlifters. Generally spouted most by guys who have used loads of steroids and are huge, have no idea what is happening to their bodies and then share that same cluelessness with others who make the false assumption that their experience means that they have knowledge.

Watch who you listen to. Seriously. They are everywhere, sharing their knowledge - B5150.
"I never had any hairloss when I pinned the testosterone in my butt cheeks, but when I tried pinning in my bicep, I went bald" is some broscience you could find in a forum, or a gym
