Compound reference

What each molecule actually is, what the research has examined, how strong that evidence is, and where UK law stands. Written as a reference rather than a sales page, because the existing options are a supplier listing with a price on it or an argument on a forum.

We sell equipment, not compounds. Nothing on these pages is for sale here, and nothing on them is medical advice or a recommendation. They describe what has been studied. They do not tell you what anything will do for you, and they contain no dosing information.

Evidence levels, and why they matter

Every page carries an evidence label. It is the most useful thing on the page and the thing supplier listings never tell you.

Human trialsRandomised controlled trials in people. A different category of confidence entirely.
Early human dataSmall or exploratory studies in people. Suggestive, not settled.
Animal studies onlyUsually rodents. Most compounds discussed online sit here, and most promising animal results never reproduce in humans.
Laboratory onlyCells in a dish.

A compound with impressive rat data and no human trials is not a proven anything. That distinction is the whole point of this section.
