0.8g per pound of protein covers all muscle growth: beyond that is waste

49 randomized controlled trials and nearly 2,000 subjects later, researchers at McMaster University found your muscles stop responding to protein at 0.73 grams per pound of bodyweight per day, not the one gram per pound that gym culture has been preaching for decades. For a 180-pound person, that gap means eating roughly 47 extra pounds of protein per year with zero additional muscle to show for it. The one-gram standard was never backed by dose-response data, it just got laundered through bodybuilding forums and supplement marketing until everyone forgot to ask where it came from.

Fadogia agrestis has no human trials: only rat data exists

Millions of men are taking Fadogia agrestis to boost testosterone and the entire scientific foundation for that decision is one rat study from 2005 — zero human trials, ever. The same paper that showed elevated testosterone in rats also showed dose-dependent toxicity, and that part somehow never made it into the podcast ads. Tongkat ali at least has five human RCTs behind it, but that evidence belongs to a completely different plant, and the supplement industry has been quietly borrowing its credibility to sell something that has never been tested on a single human being.

Sleep regularity: 60,000 people show consistency beats duration

Sleeping 8 hours means nothing if you're doing it at different times every night — a 60,000-person study just proved consistency beats duration when it comes to staying alive. People with the most irregular sleep schedules had a 53 percent higher risk of dying from any cause, even after researchers controlled for how much sleep they were actually getting. The metric we have been told to obsess over for decades, total hours, turned out to be the weaker signal.

700 studies on creatine and the answer is simpler than you think

After 700 studies across 30 years, scientists didn't land on some cutting-edge compound or patented formula -- they landed on a $15 tub of creatine monohydrate, which the International Society of Sports Nutrition officially called the most effective ergogenic supplement available to athletes. The kidney damage fears? Not supported by controlled research in healthy people. The fancy branded versions with better "absorption"? A marketing story, not a science one.

TikTok bone smashing debunked: what actually builds facial structure

Young men on TikTok have been hitting themselves in the face with rocks and hammers trying to sharpen their jawlines, citing a 132-year-old bone biology principle called Wolff's Law — and oral surgeons are now treating them for nerve damage and microfractures. The science they are quoting is real, but they are applying it so wrong that bone researchers do not even consider it a debate. The actual path to jaw definition is dropping body fat below 15 percent, chewing hard mastic gum to build your masseter muscle, and fixing your posture — none of which require hitting yourself in the face with anything.
