How the compound library is written

The compound library is a plain-English reference to the medicines and substances Enhanced Training Studio can log. It exists so people who track their health can read what is actually known about something, with the evidence and the risks, in one place.

What each page covers

• What the substance is, and its legal and regulatory status in the UK, US and EU.
• How it works, and what it is approved for, if anything.
• What the research shows, with the strength of the evidence stated plainly.
• Known risks and side effects.
• The blood tests that guidelines or product labels mention monitoring.
• The sources for every claim, at the end of the page.

What we never publish

• Doses. No amounts, ranges, schedules or course lengths, even for approved medicines. Only a prescriber who knows your history can set a dose.
• Protocols. No cycles, combinations, "post-cycle" plans, mixing or injection instructions.
• Sourcing. No suppliers, products, prices or ways to obtain anything.
• Anything about avoiding detection, in sport or anywhere else.
• Performance or appearance claims. Research results are reported in the words the studies used.

Sources

We use product labels and summaries of product characteristics (FDA, EMA, the UK electronic Medicines Compendium), regulators (FDA, EMA, MHRA), clinical guidelines (for example the Endocrine Society), the NHS, NCBI's LiverTox, clinical trial registries and peer-reviewed journals. We don't use forums, sellers, supplement sites or encyclopaedias. Each source is opened and checked before it's cited.

Evidence labels

Every page carries one label:

• Approved medicine: approved as a prescription medicine in the UK, US or EU for at least one use in people.
• Former or veterinary: approved for people only in the past or elsewhere, or only for animals.
• Investigational: being tested in human clinical trials, not yet approved.
• Limited human evidence: little human data beyond small or old studies, case reports or animal research.

Reviews and corrections

Each page shows the date it was last reviewed. Regulatory status changes, so status lines say "as of" a date. If you spot a mistake or an out-of-date source, email [email protected] and we'll check it and correct the page.

Not medical advice

The library is general information. It isn't medical advice and doesn't replace a doctor or pharmacist. Many of the substances described are prescription-only or controlled, and several are not approved for use in people at all. Enhanced Training Studio doesn't sell, supply or recommend any substance.
