How we review

This page explains how articles and tools on this site are made, what we check, and what we leave out.

Who checks the articles

Articles are written and checked by the TTG Editorial Team. We don’t currently have a medical reviewer, so no page on this site carries a medical-review label. If a verified clinician reviews a page in the future, that page will say so and give the review date. Until then, treat everything here as general information and talk with a clinician about your own situation.

Sources

Every medical claim links to a source. We look first to medical societies and public health bodies, such as the Endocrine Society, the American Urological Association, the National Institutes of Health and MedlinePlus, and the Centers for Disease Control and Prevention, and to peer-reviewed papers. The sources for each article are listed at the bottom of the page.

Reference ranges

When we show a range, it is a published reference range, with its source and the group of people it describes. Ranges differ between labs and methods, so the range printed on your own lab report is the one that applies to your result. We don’t set “optimal” targets, and we don’t give dosing or treatment advice.

How we choose what to recommend

We recommend the smallest, lowest-priced test that answers the question a reader came with. Earning a commission does not change that. If a cheaper test fits, that is the one we point to.

Prices

Every price we show carries the month it was checked, and the current price is always on the seller’s site. We don’t show crossed-out list prices as savings.

Tools

Our tools use published methods and say so. The free testosterone calculator is labelled as an estimate, not a diagnosis, and links to the paper its formula comes from. Values you enter stay in your browser.

Updates and corrections

Each article shows the date it was last updated. If you find a mistake, tell us through the contact page. We correct errors and change the updated date when we do.

What we don’t publish

We don’t publish blood work for steroid cycles, advice on buying or dosing peptides, or content promoting products sold to raise testosterone. We don’t suggest ways around the state restrictions of a lab service. We don’t make claims that a test is “the most accurate” without a source.
