Bone Density and Healthy Aging
Why skeletal health quietly determines independence in later decades.
Read →GLP-1 vs Growth-Hormone Peptides: Different Goals, Different Evidence
Two peptide categories often lumped together — and the wildly different levels of proof behind each.
Read →The Minimalist's Guide to Recovery
If you only did three things for recovery, the research says these are them.
Read →Reading a GLP-1 Headline Without Getting Misled
A practical guide to the difference between a trial result and a press release.
Read →Heat Acclimation and Adaptation
How deliberate heat exposure builds a kind of fitness — and aids recovery capacity.
Read →DHEA, Hormones, and Aging
A popular anti-aging hormone supplement, weighed against the modest evidence.
Read →GLP-1s and Bone Density: An Open Question
Rapid weight loss can affect bone. What the limited data shows and why it's worth watching.
Read →Injection Technique and Peptides: What the Research Suggests
Site, depth, and rotation shape both safety and absorption — but the evidence comes from insulin, not peptides.
Read →Recovery and Travel: Managing Jet Lag
Light timing and melatonin for crossing time zones, and what the Cochrane review actually found.
Read →Cognitive Reserve and Brain Aging
The buffer that protects thinking with age, and how it's built.
Read →The Economics of Peptide Research: Why Trials Lag
Pivotal trials cost millions and patents fund them. Unpatentable peptides break that model — which explains the evidence gap.
Read →Why Sleep Beats Every Recovery Gadget
Before the plunges and the devices, there's the unglamorous tool with the strongest evidence: sleep, including a controlled trial in athletes.
Read →Semaglutide and Cardiovascular Risk: What SELECT Actually Showed
The SELECT trial found a 20% reduction in major cardiac events in people with heart disease and excess weight — and it changed the drug's FDA label.
Read →Bioregulator Peptides and Aging: A Skeptical Review
Decades of work from a single Russian institute, almost no independent Western trials, and sweeping longevity claims.
Read →Recovery Heart-Rate and Fitness
How fast your pulse falls after effort is a real prognostic marker, but a noisy daily number.
