Guides — how a personal research protocol works

The research library explains the compounds and the goal pages explain the goals. These guides explain the machinery in between — how the arithmetic, the labs, the documents and the cycle actually work — so that you can read any protocol, ours included, and check it yourself.

Before you read onResearch and educational information for adults, not medical advice. Guides explain how a personal research protocol is built and read — they are not your protocol. Baseline labs come before anything, and your own physician has the final word. Longevity Bros offers coaching and written research protocols only — we do not sell, supply, source or ship any compound.

A personal research protocol is a written plan for one adult and one goal, built from an intake and a set of labs, reviewed by a second person and released by a coach. It is not complicated, but it has moving parts that are easier to use once you have seen them laid out: a pen is 300 clicks and the dose per click depends on the pen; labs decide what leads and whether a dose holds, steps or stops; three documents say the same thing at three depths; the budget option is written before the upgrade; a cycle has a shape; and switching from a prescribed GLP-1 medicine is phased, never stacked.

Each guide below covers one of those parts in about a thousand words, links to the compound and goal pages it depends on, and ends with the questions we are asked about it most. None of them contains a dose for you — doses live in your own protocol, after your labs have been read — and none of them describes how a dose is physically taken; that is a conversation with your coach and your physician.

The guides

Where the guides sit

Suggested reading sequence

If you are about to start the intake: baseline labs first, so the draw can be booked now. If a protocol has just arrived: how to read your protocol, then pen clicks to check the fridge page. If you are deciding between the options: combo versus separate pens. If you are on a GLP-1 medicine: the transition guide, and take it to your prescriber.
