The WT3 Protocol, Explained in Dr. Wilson's Words

“WT3 protocol” appears on nearly every page of this site, and it is easy to nod along without ever having seen it defined. This guide assembles the definition from the doctor’s manual and from the one peer-reviewed description of the protocol, so a patient can understand what is being proposed and a physician can find the chapters that spell it out. It is a description, not an instruction: T3 is a prescription medicine and the protocol is run by a doctor.

The one-paragraph version

The manual’s own quick sketch:

Involves the use of pure T3 powder mixed with a sustained release agent usually administered in capsules. Patients take increasing doses according to a schedule and their signs and symptoms. After the signs and symptoms resolve, the treatment can be tapered off after a time. Sometimes more than one “cycle” of treatment is needed to fully correct the problem.

And the description in the 2006 clinical report in the Puerto Rico Health Sciences Journal — the protocol’s peer-reviewed footprint:

The WT3 protocol involves the use of SR-T3 taken orally by the patient every 12 hours according to a cyclic dose schedule determined by patient response. The patient is then weaned once a body temperature of 98.6 degrees F has been maintained for 3 consecutive weeks.

Four ideas are packed into those two passages: sustained-release T3, a 12-hour interval, a cycle that goes up and then comes down, and a temperature target that decides when.

Goal one: get the temperature up — steadily

Feeling well on T3 therapy has everything to do with the T3 stimulation being strong enough to get the temperature up to normal, and steady enough to be well tolerated. With T3, steadiness is everything.

With T3 levels, STEADINESS Is Everything. This cannot be over-emphasized.

The lower the dose of exogenous T3 therapy the easier it is to keep the T3 level steady.

— Treatment Principles, the doctor’s manual

Steadiness is why the protocol uses a compounded slow-release preparation rather than instant-release tablets (the manual’s reasoning is collected in Sustained-Release T3 vs Cytomel), and why the caveats chapter opens with:

The whole trick is to start with a steady level of T3 and keep it steady (see Q13).

Goal two: reset, then leave

The distinctive claim of the protocol is that improvement can outlast the medicine. The manual calls it “capturing” the temperature, and the quick sketch names the phenomenon:

Remarkably, patients’ temperatures and symptoms often remain improved even after the T3 therapy has been discontinued. This is an encouraging sign that suggests the treatment is corrective, not palliative. We call this the “resetting phenomenon.”

— A Quick Sketch of Wilson’s Temperature Syndrome, the doctor’s manual

The manual’s analogy for this is deliberate and worth reading in full, because it is also the analogy the 2006 paper reaches for:

Just as patients must frequently be cycled on ocp’s several times, so too do Wilson’s Temperature Syndrome sufferers frequently need to be cycled on and off T3 therapy more than once to fully re-establish the preferable thyroid hormonal milieu that corrects the symptoms, and that the patient’s own body can maintain naturally.

— Treatment Principles, the doctor’s manual

Why more than one cycle

The explanation the manual gives for repeated cycles is mechanistic — Dr. Wilson’s model of T4, T3 and reverse T3 competing at the cell:

It sometimes takes more than one cycle of T3 therapy to even get the temperature up to normal (which is not necessarily the same as capturing the temperature).

When the first cycle of T3 therapy is weaned and the patient’s own T4 production begins to come up again, with less RT3 around to compete against it, the T4 to T3 conversion pathway is more favored than previously (which favors a smaller T4/RT3 preponderance than previously).

— Treatment Principles, the doctor’s manual

The caveats chapter states the practical consequence:

The closer patients’ temperatures are brought to 98.6, the less medicine they’ll need on subsequent cycles (if such cycles are needed at all) (See Q14).

Nevertheless, by weaning off the T3 therapy and starting another cycle, patients are often able to get their temperatures up on much lower doses (which are easier to keep steady). Thus, with patients often requiring less and less medicine on subsequent cycles than they did on previous ones, they are often able to wean off the T3 therapy completely with their temperature and symptoms remaining improved.

— Caveats for T3 Therapy, the doctor’s manual

Whether that model is right is exactly what the critics dispute; the reverse-T3 part of it is collected in Reverse T3 and Low Body Temperature.

Weaning

Coming down has its own rule:

When weaning, the goal is to wean slowly enough that the patient’s temperature doesn’t drop.

What the published report found

The 2006 paper is a report on eleven patients, not a controlled trial, and this site describes it as such everywhere it is cited. Its result, verbatim:

We report the results of 11 patients who underwent the WT3 protocol for the treatment of CFS. All the patients improved in the five symptoms measured. All patients increased their basal temperature. The recovery time varied from 3 weeks to 12 months.

— Friedman, Miranda-Massari & Gonzalez, P R Health Sci J 2006;25(1):23–29, PubMed 16883675

The same abstract records the controversy in the same breath: the treatment “is not based on a measured deficiency of thyroid hormone”, which is the American Thyroid Association’s objection. Both sides are on the objection hub.

Where the details live

For physicians, the protocol is the manual: Treatment Principles for the goals and the model, Timing of Doses, Compliance for the 12-hour rule, Unsteadiness and the T4 Test Dose for side effects, the Caveats and the 35 clinical Q&As. Dr. Wilson also recorded a 30-minute tutorial series. For patients, the plain-language version is Medical Treatment of Wilson’s Temperature Syndrome, and the way in is a practitioner who knows it.

This is a reader’s guide compiled from Dr. Wilson’s published writing and one published report; every quotation links to its source. It describes a prescription protocol and is not a dosing instruction or medical advice.
