Biohacking insights
Peer-reviewed biohacking research, translated into plain English.
What does the lean mass number on a DEXA scan mean?
The lean mass number on a DEXA scan has a published threshold for 'low', and in 1,372 adults over 50 it tracked spine fractures better than body fat did.
Does hyperbaric oxygen therapy work? What the trials actually tested
The trial evidence for hyperbaric oxygen therapy sits in wounds that will not heal. The ageing and brain claims rest on reviews, not randomised trials.
Does BPC-157 work? Three human studies, all of them pilots
Does BPC-157 work? In rodents, injured tendons heal faster. In people the entire record is three pilot studies, one of which enrolled two adults.
Does PRP work for hair loss? Some regrowth, inconsistent evidence
PRP injections use your own blood to try to treat hair loss. In pattern baldness the evidence shows modest regrowth, no standard protocol, and no cure.
Does red light therapy work for wrinkles? One trial used a dummy mask
Does red light therapy work for wrinkles? In a 16-week trial, 60 adults used a light mask or an identical dummy - raters saw the difference.
Are executive health check-ups worth it? The trials tested a simpler check
Executive health check-ups bundle dozens of tests. The randomised evidence covers a plainer version, and across 233,298 adults it did not move the death rate.
Does red light therapy work for hair loss?
Red light therapy grows measurably more hair than a dummy device in pattern hair loss, but the trials are small and rarely test the machines clinics sell.
Hyperbaric oxygen therapy side effects: how common are they?
The usual hyperbaric oxygen therapy side effects are ear pressure pain and temporary short-sightedness. Serious problems are rare. Here are the numbers.
