The phase you are in determines what to do next
Most researchers who are not seeing the results they expected are not using the wrong compound. They are using the right compound at a point where the limiting variable has already moved.

The four phases and what limits each one
Fat loss on a GLP-1 does not fail because a compound stops working. It moves through phases, and at each phase the variable controlling results shifts. A compound that suppresses appetite is doing exactly the right thing while intake is the limiting variable. That same compound, at the same dose, does not increase energy output, restore how efficiently cells produce energy, or improve recovery capacity.
So the question that changes everything is not which compound should I use. It is what is the limiting variable in my system right now. The four phases below answer that one question, and the explorer lets you move through each of them to see where a protocol sits.
Watch first
This video walks the same four phases from the beginning of a protocol to the end. It states the phase logic more firmly than the framework does now, so where the two differ the text on this page is the updated version. The idea is the same, the framing here is tighter.
Intake
Limiting variable: intake
The compound is doing what it is supposed to do. Appetite is suppressed, the scale is moving, and energy is stable.
Signal to look for: scale moving, appetite suppressed, energy stable.
The bar under each phase shows roughly where that phase sits between the intake side of the equation and the recovery side. Phase 1 sits almost entirely on the intake side. By Phase 4 the controlling variable has moved almost entirely to the recovery side, which is why a tool aimed at intake has progressively less to act on as the protocol moves right.
| Phase | Limiting variable | Signal to look for |
|---|---|---|
| Phase 1 | Intake | Scale moving, appetite suppressed, energy stable. The compound is doing its job and the task is protecting lean mass in the first weeks. |
| Phase 2 | Output | Scale slowed or stopped while intake is controlled. The variable has moved from how much goes in to how much is burned. |
| Phase 3 | Efficiency | Training heavier, recovery slower, flat energy on rest days. How efficiently cells produce energy has degraded, so restoration is the question rather than more demand. |
| Phase 4 | Recovery capacity | Sleep degraded, morning readiness gone, stalled across every metric. The overnight repair window is the ceiling. |
Why phase identification comes first
Most researchers who hit a wall do the same thing. They adjust the dose, they add a compound, or they switch to something stronger. The results do not improve and sometimes they get worse. The compound is one of several variables in play, and phase is the one most often skipped.
Escalating intake suppression in a phase where intake is no longer the limiting variable adds demand to a system where the constraint has already moved, so the change may not produce what is being measured for. That is the mechanism behind most of the stalls in this guide.
Before any compound question. Peptides amplify what is already present. They do not replace infrastructure. If sleep is poor, stimulants are high, stress is unmanaged, and nutrition is inconsistent, every compound in this guide will amplify the instability rather than correct it. The foundation check in part two is not optional, and it is the cheapest thing on this page to rule out.

Part two
The foundation gate
Before any compound is added at any phase, four foundational inputs need checking. Research consistently suggests that compounds added on top of unstable foundations produce a fraction of their documented effect. This is not a soft recommendation. It is a diagnostic filter, and it runs before the phase question rather than after it.
If any of the four below are genuinely compromised, resolving that is the first thing to look at, not a compound addition. Work through the list and a read appears underneath it.
Nothing checked yet. Work through the four above and a read will appear here.
Interpretation note. None of these four are settled outcomes for any individual. They are inputs that shift a distribution. A researcher reading a flat result on a compromised foundation may be reading the foundation rather than the protocol, and those two situations point at different next steps.
Part three
Where Phase 2 and Phase 3 overlap
Phase 2 and Phase 3 overlap more than the clean framework suggests. This is the section advanced researchers will want to read twice, because it is where a correct framework produces a wrong answer.
Cortisol load, training volume, and sustained restriction can push a protocol into Phase 3 territory while the scale data still looks like a Phase 2 problem. A researcher in that situation who applies the Phase 2 response is adding metabolic demand to a system that is already under strain. The plateau does not resolve, and the intervention looks like it failed when the reading was the thing that was off.
The three signals that separate them
Three signals suggest Phase 3 is running underneath a Phase 2 presentation. Answer each one below against what you have actually observed rather than what you would expect, and the tally will show which profile your signals are pointing at.
Why this matters before part four. If any of these three are true alongside a fat loss plateau, research suggests ruling out Phase 3 before applying a Phase 2 response. Part four asks a related but different question, which is what the scale and intake data show. Where these signals imply an answer there, it appears as a suggestion you can confirm or override rather than something filled in for you.
Part four
Identify your phase
Most researchers who read the phase descriptions feel confident they identified their phase correctly. That confidence is usually right in the broad sense and wrong in the details, which is why these are asked in order rather than all at once.
Each question appears once the one above it has been answered. Some answers settle the read on their own, and when that happens the questions below stop, because asking a question that cannot change the answer implies it is still in play.
Question one
Is the scale still moving consistently week over week, with appetite meaningfully suppressed and energy stable or slightly elevated?
Question two
Has training performance dropped, has recovery slowed, or is fatigue present on rest days?
Question three
Has sleep quality degraded, has morning readiness collapsed, or has progress stalled across every metric regardless of adjustments?
Question four
With intake feeling controlled, has the scale slowed while energy has started to decline?
What this returns and what it does not. This sequence returns the variable worth looking at next. It does not return a compound decision, and it does not resolve an individual variable on your behalf. A framework read is a starting point for a question, not an answer to one.
Part five
What this guide does not cover
This guide identifies the phase. It does not work through the compound framework inside each one, because that decision depends on variables this page cannot see. The resources below pick up where the map stops.
| Resource | What it covers |
|---|---|
| Protocol Stall Guide | Phase 2 in full. The complete diagnostic framework for fat loss plateaus including the GLP-1 audit, compound specific stall patterns, and the step by step Phase 2 decision path. Free. |
| Research Protocol Bible | The compound framework across all four phases. Covers Phase 3 and Phase 4 in full including the efficiency and recovery categories, the foundation gate in detail, and the full bottleneck diagnostic system. |
| Compound Diagnostic | Works through the compound being run and points at the most likely reason a result has stalled. Useful once the phase is settled and the question has become compound specific. |
If the phase read from part four came back unresolved, the search engine covers each of the individual variables on its own. If it came back specific, the Protocol Audit is where a framework read becomes an analysis built against your actual inputs.

When the framework is not specific enough
A personalized read built from your exact protocol inputs identifies what is most likely limiting progress, what is already working, and what the research suggests adjusting over the next four to six weeks.
