Phase 4: T3 Thyroid Therapy (Rebooting Your Metabolism)

Many people with chronic illness are stuck in a state where their body is “hibernating” to save energy. Even if your blood tests look normal, your body might not be using thyroid hormones correctly. This phase uses a hormone called T3 to “reboot” your body’s thermostat and turn your energy back on.

Is This Therapy Right for You?

Main Requirements (You must have these)

1. Low Waking Temperature:Is your temperature consistently below 36.5°C (97.7°F) first thing in the morning? This is the main sign your metabolism is slow.
2. Low Heart Rate:Is your resting heart rate below 72 beats per minute? This also suggests a slow metabolism.
Note: If your resting heart rate is above 90 bpm, resolve that first — elevated resting HR is a contraindication for starting T3 therapy.

Other Common Symptoms

(Check how many you have – the more you have, the more likely you need this)

Quick Check:

Low Morning Temp + Low Pulse + 3 or more symptoms You may be a good candidate for T3 therapy.

Track your temp and pulse for one week to be sure.

Getting an Accurate Temperature Reading

Use a Basal Body Thermometer, Not a Standard One

Your waking temperature is one of the most important data points in this entire protocol. A cheap drugstore thermometer that reads to one decimal place is not good enough. You need a thermometer precise enough to detect meaningful shifts, the kind used for tracking fertility windows.

Digital basal body temperature thermometer for precise tracking

A digital basal body thermometer that reads to two decimal places and holds the result for easy reading

What to Use:A digital basal body thermometer, the kind sold for fertility tracking (ovulation monitoring). These read to two decimal places (e.g., 36.48°C rather than 36.5°C), which gives you the precision needed to track real trends over days and weeks. They are inexpensive and widely available online or at pharmacies.
How to Take It Correctly:Place the thermometer under the tongue and hold it there for at least 60 seconds before the reading locks. Most standard thermometers beep too early. A basal thermometer is designed to wait for a true stable reading. Take it before getting out of bed, before drinking anything, and at roughly the same time each morning. Movement, eating, and even sitting up will raise your temperature and give you a false reading.
What You Are Looking For:Log your temperature every morning. You are tracking a trend, not a single number. As T3 therapy works, you should see your waking temperature gradually climb toward 36.5–37.0°C (97.7–98.6°F) and stabilize there. Erratic readings, persistent sub-36°C temperatures, or a temperature that rises but then drops again are all meaningful signals worth noting.

Introduction to T3 Therapy

Overview: This therapy uses T3 (thyroid hormone) to help with fatigue and low body temperature. The goal is to “restart” your metabolism. You can dive deeper into it on this site: wilsonssyndrome.com

Wilson’s T3 Therapy & Dry Fasting for Chronic Illness: a detailed breakdown of why this combination works when nothing else has.

The Best Way: Slow-Release T3 (SR-T3)

We strongly recommend using Slow-Release T3 (SR-T3).

Where to Get T3

One trusted source for Slow-Release T3 is chronic-illness.st. They specialize in this medication and can ship to many places. (Previously chronic-illness.ca — the site has recently migrated.)

Why Your Blood Tests Might Lie to You

The Real Problem: Tissue-Level Resistance

Most doctors look at your blood to see if you have enough T3. But just because T3 is in your blood doesn’t mean it’s getting inside your cells where it’s needed. This is called tissue-level resistance.

Think of T3 as a “key” and your cells as “doors.” In many sick people, the locks are jammed. The T3 keys are floating around in the hallway (your blood), but they can’t get into the rooms (your cells) to turn on the power. When a doctor draws your blood, they see plenty of keys and say, “You’re fine!” Even though your body is actually starving for energy.

Brain Insulin Resistance

This problem is especially serious in the brain. When T3 can’t get into your brain cells correctly, it leads to a type of “brain insulin resistance.” This causes major brain fog, memory problems, and severe fatigue. Even if you eat enough food, your brain can’t use that energy properly without the T3 “key” to unlock the process.

Other Signs of Resistance:

T3 therapy is used to “electrify” the body, sending a structured “electrical signal flood” of abundance and shock to finally force those jammed locks open and wake your body up. This convinces the cells that T3 can enter again and radically increases insulin sensitivity. Depending on the case, this may require a mix of T4 and high T3, or just T3, but the concept of a short, powerful energy burst remains the same. Do not forget to understand the critical co-factors required for T3 therapy to be safe and effective.

The Role of Genetics: In some cases, your genetics can play a big role in how your body handles T3. Fasting, stress, and low-carb can have different effects on different people. To learn more about this, visit the Genetic Polymorphisms page.

When to Start T3: The Fasting Block Integration

Start T3 on Day 3 of the Water Fast, Not After

In the Scorch Protocol, T3 therapy does not begin at the refeed. It begins on day 3 of the water fast that follows the 5-day dry fast. This timing is intentional.

By starting T3 on day 3 of the water fast, you are on T3 day 3 when you have your first calories. This matters because T3 needs to already be running when refeeding begins It supports your metabolism, keeps your kidneys in a stronger state, and crucially, it means your antiviral protocol (L-lysine + monolaurin) can start immediately on refeeding day 1. You do not need to wait for kidney rehydration before beginning antivirals.

The Ramp During the Fast:Follow the standard 15 mcg/day climb. Water fast day 3 = 15 mcg (T3 day 1). Water fast day 4 = 30 mcg (T3 day 2). Water fast day 5 = 45 mcg (T3 day 3). You then continue climbing into the refeed from there, with T3 day 4 being your first day of eating.
Also a High-Risk Window for Viral Reactivation:When T3 cycles end and doses taper down, your metabolic rate temporarily dips. This creates the same energetic trough that triggers herpesvirus reactivation during the fast-to-refeed transition. Continue antiviral coverage during T3 wind-down until your waking temperature has stabilized at your baseline for 5–7 consecutive days.

The 30-Day T3 Cycle

This plan is designed to wake up your body’s metabolism. It involves a 10-day “climb” followed by a 20-day “descend.”

PhaseTimeWhat to Do
The Climb10 DaysThe Hike Up: Increase your total daily dose by about 15 mcg every single day.
Example: Day 1 = 15mcg, Day 2 = 30mcg, Day 3 = 45mcg...
Note: Split your total dose into two parts: one in the morning and one in the evening.
The Peak1–3 DaysStay at your highest dose for a few days to “break” your metabolism’s resistance. If your heart races or you feel anxious, stop increasing.
The Taper20 DaysThe Hike Down: Slowly lower your dose back to zero.
This lets your thyroid start making its own hormones again without a crash.

Safety First

Is your heart racing?If your resting heart rate is over 100 beats per minute, STOP INCREASING. Stay at your current dose or lower it until your heart rate slows down.
Are you using “Instant” T3? WARNING: This fast 10-day climb is only for Slow-Release T3. Do not try this with regular “instant” T3 unless you are very careful and take many small doses throughout the day.
Having trouble stopping? If you feel bad while lowering your dose, your doctor might suggest a small dose of T4 to help your body adjust.

Keeping Your Progress

Fueling T3 Therapy: Why Calories Matter Here

T3 dramatically increases your metabolic rate. That is the point. But a faster metabolism with insufficient fuel will cannibalize muscle. You must not be in a caloric deficit during this phase.

Match Your Caloric Demand:As T3 doses climb, your body burns more energy. If you are not eating enough to cover that demand, the body will turn to muscle tissue for fuel, the opposite of what you are trying to achieve. Keep calories at or above your target (see the Refeeding page) and prioritize protein to give your body something to build with, not just burn.
Move Your Muscles: Tell Your Brain to Keep ThemPhysical movement during T3 therapy sends a preservation signal. Your body will not aggressively break down muscle tissue it is actively using. You do not need to train hard. Even walking, light resistance work, or bodyweight movements daily is enough to keep the muscle-sparing signal active. Lying still while on T3 with insufficient calories is the worst combination.
When You Cannot Hit High Calories Yet:Some people, especially early in the refeed, cannot physically eat enough to match T3’s demand. Their gut is not ready, appetite is suppressed, or digestion is too compromised. In this case, there are specific strategies that can help:
  • hGH: directly shifts the body toward anabolism and preferential fat use, reducing the rate at which muscle is burned for fuel even when calories are temporarily low.
  • Retatrutide: a GLP-1/GIP/glucagon triple agonist that improves glucose utilization and raises baseline energy availability. The glucagon component is particularly useful for people stuck in low-energy states.
Important: If you do not understand how hGH or Retatrutide work and why they are recommended in this context, do not use them. These are not general supplements. They are targeted tools with specific mechanisms. Read the hGH Therapy page and understand the protocol before considering them.

Life to Your Mortal Body: The Spirit That Raises the Dead

Sunrise over a valley, awakening and new life

Romans 8:11: “And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you.”

The thyroid is not broken. It has gone quiet. T3 is the spark that calls it back. The morning my metabolism came back online after years of crashing was one of the most spiritual experiences of my life. Not dramatic. Just warmth, where there had been cold. Energy, where there had been nothing. The body recognizing itself again. The same Spirit that raised Christ from the dead dwells in you. If He can do that, He can wake up your cells. If you have been sick long enough to stop believing this is possible, that is exactly where this protocol meets you.
