How we source and review our content

Where our facts come from

Health and science statements come from official and primary sources:

• documents from FDA and other regulators, including warning letters and drug labels such as those published on DailyMed;
• National Library of Medicine resources, including PubMed, PubMed Central, PubChem, MedlinePlus and ClinicalTrials.gov;
• peer-reviewed journals;
• public health and sport bodies, such as the CDC, the World Anti-Doping Agency and the US Anti-Doping Agency; and
• official company documents, such as a drug's prescribing information or a syringe maker's product specifications.

We do not use vendor pages, clinic marketing, blogs, forums or Wikipedia as sources for health facts. Our supplier's pages are used only for product facts, such as what a vial holds. City pages also draw on census, weather, mapping and local government records, and sometimes local news, for facts about each place.

When an official record has not been published yet, we may report what trade press says, name it as trade press, and recheck the fact once the official record appears. For example, FDA's page for its July 23 to 24, 2026 advisory committee meeting on seven peptides still showed no minutes or vote results when we checked it on October 25, 2026.¹ Our research sheet therefore records the vote as reported by the trade publication AJMC² and flags it for a recheck.

How a fact reaches a page

Before anything is written, each compound and topic gets a research sheet. Every fact on a sheet is tied to its sources. Each source is stored with its title, publisher, web address, type and the date it was accessed, plus the passage the fact rests on. The access date shows how current a fact is, which matters most for regulatory facts, because rules and enforcement change.

Writers take health facts only from these sheets and copy each source entry unchanged. If a fact a page needs is not on a sheet, it is left out and logged as an open question, not filled in from memory. A new source can be added only after it has been opened, read and found to meet the rules above.

How we cite

Each health statement carries a numbered citation right after the claim, and the numbers match the source list at the end of the page. When a statement is not a label fact, the sentence names the evidence behind it, so you can judge its strength. Examples are "in rats", "in cell studies", or a human trial named with its length and the number of people in it.

Rules for health content

• Approved medicines are described from their FDA labels, including the label's dosing schedule, and pages say that the prescriber sets the dose.
• Dosage pages for other compounds give only doses used in published studies, with the species, route and duration, and state that no human dose is established.
• No page gives a dose, frequency, cycle or protocol for a person for a compound that is not an approved medicine, and no page says a product treats, cures or prevents anything.
• Injection content describes how prescribed injectables are given, from clinical sources, and how to dispose of sharps. It never explains how to inject a research compound.
• GLP-1 research vial product pages carry no prescription, clinic, insurance or brand-price content and no comparison with prescription brands. Pages about the brands state label facts only and never point to a research vial as a substitute or a cheaper option.

Store facts come from data

Writers do not type prices, strengths, stock status, ship-from origins or business details. Pages pull them from our product and business data when the site is built. If a business fact is not set yet, such as a delivery time, the page leaves it out instead of guessing.

Review before publishing

Pages that make health statements are checked by a qualified reviewer before they go live. A reviewed page shows the reviewer's name, credentials and review date. Until a page has passed review, the build leaves it off the live site.

Each page's file also goes through an automated validator. It confirms that every citation points to a listed source and that every listed source is cited. It also checks that every internal link leads to a real page and that no price is typed by hand.

Our conflict of interest

We sell many of the compounds we write about. The rules on this page exist partly to manage that. The same sourcing and citation standard applies whether or not we sell a compound. Every compound profile has a side effects section and a regulatory status section, and education pages use buying words only in links to product pages.

Corrections

If you find an error, tell us through the contact page. Name the page, the sentence and, if you have one, the source that shows the problem. We check the claim against its cited source. If the page is wrong, or the source has been replaced by a newer one, we correct the page and update its date. The writers behind these pages are described on the editorial team page.
