Editorial policy

How we research, write, review and correct every page.

Sources we use

In order of preference: official prescribing labels (FDA, EMA), peer-reviewed clinical trials, systematic reviews, peer-reviewed preclinical studies, and official regulatory notices (FDA, WADA, national regulators). We do not use vendor websites, forums, social media or "protocol" sites as sources.

How we write

Doses

Doses in the “Doses studied in people” tables come only from published human studies or official labels, with the source cited next to the number. Weekly protocol charts may also show protocols commonly reported in public sources; these are always labeled “Commonly reported, not studied”, kept separate from trial and label doses, and cited. Reporting a protocol is not a recommendation. These are reported for reference and are not recommendations. Our calculator and reconstitution guides do arithmetic and explain general laboratory practice. They do not tell anyone what amount to use.

Research process

Profiles are drafted with the help of AI research tools that gather and summarize primary sources, then checked against those sources. The date each page was last reviewed is shown at the bottom of the page. Regulatory status changes often; check the linked sources for the latest position.

Independence

This site carries no advertising for compounds, takes no payment from manufacturers or sellers, and does not link to vendors.

Corrections

We correct factual errors as soon as we confirm them and update the review date on the page. If you find an error, note the page and the source that contradicts it. A dedicated corrections address is being set up.
