Creatine is the most-studied supplement in sports science, and also the most mythologized — kidney damage, mandatory loading phases, and cognitive miracle claims that don't survive a close read of the meta-analyses. A mechanistic look at the phosphocreatine system as a chemical capacitor, the real effect sizes from recent meta-analyses, why some people are non-responders, and what the cognition evidence actually supports.

Plantar Fasciitis: Mechanics and Evidence-Based Fixes The plantar fascia is a load-bearing structural element, not an inflamed tissue — the "-itis" in plantar fasciitis is a misnomer for a degenerative fasciosis. A mechanical breakdown of the windlass mechanism, why the first steps out of bed are the worst ones, the heavy-slow-resistance protocol with actual RCT numbers behind it, and an honest evidence ladder ranking every common treatment from heel raises to magnetic insoles.

The Huberman Lab Peptides Episode, Reviewed: What Dr. Bakri Said and What Survives Scrutiny In June 2026, Andrew Huberman spent nearly three hours with physician Abud Bakri walking through BPC-157, GHK-Cu, epithalon, pinealon, thymosin alpha-1, GLP-1s, and retatrutide. The episode is a genuinely useful map of what people are injecting and why. It is also a case study in how conversational time can flatten a very steep evidence gradient. A peptide-by-peptide fact-check of the claims, the mechanisms, and the regulatory maze in between.

Diet and Cognition: What the Evidence Actually Supports, and What the Marketing Sells Most diet-and-cognition claims rest on observational studies that systematically over-promise, and the few large randomized trials that tested the headline diets came back muted. A skeptical-engineer walk through the Mediterranean and MIND data, omega-3s honestly, the supplement graveyard, and the one mechanism that actually holds up.

Caffeine Pharmacokinetics for Engineers How caffeine actually works inside your body: adenosine receptor antagonism, the 5-hour half-life math that explains why your 3 PM cup is still measurable at midnight, tolerance and withdrawal as receptor upregulation, CYP1A2 genetic variation, and dose-response curves for alertness versus anxiety — written for people who reason in graphs and decay equations.
