Hiperformance Culture - The Verdict
Trends
A live claim, weighed. Each breakdown takes something currently circulating - a protocol, a supplement, a shortcut - and asks what the evidence actually supports.
The verdict is stated plainly, including when the honest verdict is that nobody knows yet.
We graded 71 trends against the evidence. 4 clear High.
