Men's Health After 40: The Sterling Field Guide

Start here

Most health spending after 40 goes wrong in the same way: a symptom shows up, a product gets blamed, and the credit card comes out before anyone checks whether the thing works or whether you even need it. This field guide is the antidote. It groups the decisions men over 40 actually face and points each one to a full Sterling dossier: what the evidence says, what to measure first, who should skip, and the next move. We sell clarity, not transformation, so several of these verdicts are simply “save your money.”

Hormones and testosterone

The most searched, most oversold corner of men’s health. Start with bloodwork, fix the basics, and treat supplements as modest support rather than a substitute for a real diagnosis.

• Testosterone Boosters Before TRT: whether to try a natural booster or go to a TRT clinic, and how to know if you are actually low.
• Tongkat Ali vs Fadogia Agrestis: which natural test booster has human evidence, and which carries a safety question.

Weight and metabolic health

The GLP-1 era changed the conversation. Here is how to decide with clear eyes, and what to measure.

• Thinking About a GLP-1?: what to ask a real prescriber, how to protect muscle, and where a natural alternative honestly fits.
• CGM for Non-Diabetics: Stelo vs Lingo: whether a continuous glucose monitor is worth it, and as a short experiment rather than a subscription.

Supplements that earn their place

A short list of supplements with real evidence, and an honest read on the hype around the rest.

• Creatine Monohydrate vs HCl: why the cheap, boring form wins, and why creatine is a top buy after 40.
• Magnesium for Sleep: which form actually helps, which to skip, and how much to take.
• NMN vs NR: NAD+ Boosters: both raise a lab marker, but the benefit is unproven, so here is the cleaner pick and who should skip.

Recovery and longevity

The habits and tools sold as longevity essentials, ranked by the strength of the evidence.

• Cold Plunge vs Sauna: which has the stronger evidence, and the cold-timing mistake that costs you muscle.

Measure before you spend

The cheapest, highest-return move is often a measurement, not a purchase. These are the devices worth owning, and the ones to skip.

• Upper-Arm vs Wrist Blood-Pressure Monitors: the validated cuff to buy, and the mistake that changes your reading.
• Smart Scales After 40: worth it for the weight trend, not the body-fat number.

How to use this guide

Pick the decision in front of you, read the dossier, and act on the one cheapest credible step it names. Then come back when the next question shows up. New dossiers land regularly, each built the same way: a clear verdict, the evidence behind it, and the honest caveat a good advisor would give you.
