Protocols people actually report

These are descriptions of what appears in published studies and in community reports — not instructions, not recommendations, and not medical advice. Every protocol carries the evidence grade of the compounds in it, and most of those grades are low.

Read this first

A protocol existing here means people documented it. It does not mean it works, that the dose is safe, or that the compound is legal where you are.

How protocols are graded here
ADrawn from a trial protocol or an approved label
BMatches the dosing used in at least one human study
CExtrapolated from animal work or small open-label use
DCommunity practice with no study behind it at all

The grade describes the source of the protocol, not whether it is safe. 5 of the 7 protocols on this page are C or D.
