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

The uninformed opinion of "meatheads" or "jocks" on topics relating to health, strength, or athletic development.
Jock: "Dude, your body only absorbs 20 grams of protein at a time and you can't train a body part more than once a week."

Informed response: "That's broscience, bro. Your stomach and liver can handle a large sirloin with more than 20 grams of protein just fine. and if you think you can train a body part only once a week, then why do you masturbate every day?"

A sarcastic term implying that the time tested, muscle building wealth of knowledge developed and utilized by successful, experienced bodybuilders is inferior to the continually shifting hypotheses of articulate, textbook-savvy 155lb. chemists with little or no real world first-person experience to substantiate their conclusions. The term "Broscience" is oft repeated on bodybuilding and fitness oriented internet forums in an attempt to demonstrate online dominance as a substitution for success in the arena of actual bodybuilding.
Professor Shnootgarten: What are you drinking there?

Tommy: Just a protein shake with some carbs; I need to get my 350 grams daily.

Professor Shnootgarten: According to the 30 pubmed studies that I’ve downloaded, any amount greater than 22.341 grams of protein post workout is superfluous for greater protein synthesis. Additionally, insulin spiking, if that’s your intended objective, is neither necessary nor helpful toward replenishing glycogen stores unless, of course, your focus is high rep, time under tension endurance tolerance rather than maximal load, low rep hypertrophy stimulation.

Tommy: Dude, over the last 8 years, I’ve gone from a 148 pound weakling to a 220 pound beast doing the same stuff that worked for my dad, and you’re a buck fifteen and have never actually seen the inside of a gym.

Professor Shnootgarten: Well, according to last year’s in-vitro study of skeletal-muscle glycogen phosphorylase done at the University of Stuttgart School of Bio-Organic Chemistry Deluxe...

Tommy: Spare me the science lesson Mr. Wizard; you’ll change your mind next week when new studies reveal the opposite conclusions. You can take your research and your weak pale self, and I’ll take the 500+lb.deadlift that I got with hard work and a little help from broscience.

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."

Anecdotal evidence presented as fact by unqualified, yet confident indvidulas in the body building community.
Rampent within liftring forums and message boards, the information is usualy based on hearsay with little to no scientific evidence to support the claims made by the individual.
Examples can be limited to a single fram of mind: It worked for me, so it works the same way for everyone!

There is actually a forum that is called broscience dot com that caters to these claims.
An example of Broscience is as follows:

Unsubstantiated Nutritional and Human physiological claims. Broscience does not ALWAYS go hand in hand with being wrong, its just that its simply UNSUBTANIATED.

Most Jacked guys claim some of these facts to be true since it "worked for them" when they fail to realize that just because it works for them, it will not always tailor to the common majority. Supplement companies tend to perpetuated Broscience so people will keep believing these myths so companies can make products that accomodate these claims so they in turn make $$. Always read, always question. If your not enjoying yourself throughout your training career your probably doing something wrong.
"If you don't eat every 2-4 hours you'll risk being catabolic at some parts of the day, bro. Vince Delmonte said you need to eat every 2-4 hours!"

That is Broscience man. Human beings would not have survived and thrived the way we do today had our dietary needs been that demanding. It's best you ignore everything Vince Delmonte says.

"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...
