We looked, and the evidence does not back the claim: either it was tested and did not hold up, or nobody has tested it and nothing that was tested supports it.
Everyone trained one arm the same way for twelve weeks. In that arm, biceps size changed by anywhere from minus two percent to plus fifty-nine, around an average of nineteen. How much of that spread is real is still argued over.
Cut 500 a day and the rule says 52 lb in a year. In supervised studies people lost less than it predicted, and a model predicts a half-time of about a year, because your expenditure falls as you shrink. Same arithmetic, a different trajectory.
Across 4,871 tests, submaximal equations put people in the right fitness third 51% of the time. Guessing gets 33%. Here is what a real test is, and when you actually need one.
The sleepy girl mocktail runs on a study that finished with eight completers. Pooled, ten trials of tart cherry show no clear effect on sleep, and the recovery evidence, though better, is not good.
We said nobody had tested a creatine gummy. Three groups had. Of 27 products, 13 held almost no creatine and 9 met their labels, while every powder tested held its label. None of the tests is peer reviewed, and every tester sells something.
Glycinate is sold on absorption. The trial built to test it found 23.5% versus 22.6% for cheap magnesium oxide, in twelve patients missing part of the bowel, and two company studies in healthy adults did not put it ahead either.
A scoping review found 19 records and three small tests of tallow creams on people, none against a moisturiser. A second study read 200 posts: nine cited any evidence.
In the Cochrane review the bandage cut swelling 30 to 38.6% and the massage added 7.11%, in 83 women; six of seven trials since found it added nothing measurable. In people without lymphedema the studies are small, and few test what it is sold for.
Swallowed, castor oil has a confirmed receptor mechanism and trials and hospital records in more than two thousand women. As a pack, the small tests found no sign it gets through skin, no change in liver tests and no difference from a dummy pack.
The signs that best pick out Cushing syndrome are physical: purple stretch marks more than about 0.4 in (1 cm) wide, bruising from nothing, weakness getting out of a chair. Tiredness is a feature too, and on its own it singles nobody out.
