What you need to know

hGH is the rebuild signal. Dry fasting clears damaged cells, T3 restores metabolic power, and hGH tells your body to build new healthy muscle and immune tissue from what was freed.
Cyproheptadine and hGH work together. Injected hGH bypasses the pituitary signal cyproheptadine blunts, so you do not need to stop cyproheptadine before starting hGH.
Some people need to eat significantly more calories than they ever have during this phase. Without enough fuel, the rebuild cannot happen. Research suggests 9 months of treatment may be needed to feel substantial results.
hGH is the preferred base: it is the actual hormone, so it needs nothing from your body to work, puts the least strain on the system, and gives the most benefit. If you truly cannot access hGH, CJC-1295 + Ipamorelin can be tried to help wake up your own pituitary, but it is an awakening aid, not a full replacement.

This phase is about using Human Growth Hormone (hGH) to help your body repair deep tissues and fix your immune system. I have used this myself and with my clients to get amazing results. Everyone’s body is a little different, so you and I have to carefully figure out how it works for you.

* Can’t get hGH? Real hGH is the preferred base: it is the actual hormone, so it needs nothing from your body, puts the least strain on the system, and gives the most benefit. If it is truly out of reach, secretagogues like CJC-1295 + Ipamorelin can be tried to help wake up your own pituitary, as an awakening aid rather than a full replacement. Ask Yannick in the portal for the adjusted plan.

Cyproheptadine and hGH Work Together

If you used cyproheptadine during your first T3 cycle (for appetite, sleep, or brain-gut calming), you do not need to stop it before hGH. Cyproheptadine blunts the pituitary’s own signal to release growth hormone, but the hGH phase injects growth hormone directly, so it bypasses the pituitary and overrides the blunting. The nighttime cortisol point does not change this: hGH here is for regeneration and calming the nervous system, not overnight fat loss, and its rebuilding actions stay active even with cortisol softened. Keep cyproheptadine going wherever appetite, gut tolerance, or sleep still call for it. See the full cyproheptadine context on the T3 Therapy page.

How hGH Works in the Body

Three angles on the same molecule: how hGH triggers the rebuild signal, how it directs fat burning, and how it shifts body composition toward muscle rather than fat. Read all three before starting hGH so the protocol logic makes sense.

How hGH Helps You Heal

Fixing Your Immune System: The Calorie & Building Flood.
Dry fasting cleans out the “trash,” and hGH sends the signal to “rebuild” through a massive calorie and building flood. This phase focuses on flooding the body with energy to signal abundance and regeneration. Some may need to eat significantly more calories than they ever have to force this process, which can take months to years. While weight gain is a common concern (see the Minnesota Starvation Experiment), it is often an unavoidable part of reclaiming your health. Success here involves maintaining insulin sensitivity while maximizing rebuilding, often utilizing peptides and ketone strategies as additional co-factors.

The “Big Three”: Fasting, T3, and hGH working together
For many people, using hGH by itself doesn’t work. To truly heal, you need all three parts of the Scorch Protocol to work together:

Phase 1: The Cleanup (Dry Fasting): This cleans out the debris and old proteins that are blocking your body’s healing signals.
Phase 2: The Power (T3 Therapy): This turns your body’s power back on. You can’t rebuild your body if you don’t have enough energy (ATP) to do the work.
Phase 3: The Rebuild (hGH): Once the trash is gone and the power is on, hGH gives the command to build new, healthy cells and “power plants” (mitochondria).

A New Way to Look at Chronic Illness

Doctors now believe that some chronic illnesses trap the body in a cycle of inflammation where low growth hormone levels stop the body from repairing itself. Using hGH helps your body stop burning sugar inefficiently and starts using its best fuel source for energy again.

How long does it take? Studies show that people with low growth hormone often need 9 months of treatment to feel better. Be patient, it takes time to rebuild your body’s energy and reverse your symptoms.

Why Fasting isn’t Always Enough: While fasting helps your body make more growth hormone at first, doing it too much or not eating enough can actually lower your hormone levels later on.

What the Research Says: One study showed that “starvation” could drop growth hormone levels by up to 50% for several months. This means some people may need extra hGH support to make sure their body keeps healing after a fast.

How hGH Helps You Burn Fat

During a fast, your body makes more growth hormone to help you burn fat for fuel. This is what helps your body make ketones, which your brain uses for energy when you aren’t eating.

The “Over-Fasting” Problem: If you fast too often or for too long, your body might stop making enough growth hormone. When this happens, you might notice that you aren’t losing much fat anymore, even if you aren’t eating. You might also feel more tired or take longer to recover. Some people mistake this for being sick again and try to fast more, but that only makes the problem worse. This is why I focus on using hGH to break that cycle.

Rebuilding Muscle, Not Fat

One of the hardest parts of the Scorch Protocol is the Refeeding Phase. After a long fast, your body is desperate for food. If your hormones aren’t balanced, your body will want to store all that new food as fat instead of muscle.

The Fix: This is where hGH therapy helps. It tells your body to use those nutrients to rebuild your muscles and organs instead of just making you gain fat.

What the Science Shows:

A study on animals showed a big difference between just eating again and eating while using hGH:

Without hGH: Rebuilding body weight was slow, and they didn’t gain extra muscle.
With hGH: They rebuilt their body weight in just 9 weeks and actually grew more muscle than they had before.

Using hGH while you start eating again ensures your body becomes stronger and leaner than it was before you started.

Practical: Sourcing and the Synergistic Stack

Once you understand what hGH does, the next questions are where to get it safely and what other peptides amplify its effect during recovery. This section covers both.

Where to Get hGH

It is very important to get high-quality hGH, as many products sold online are fake or low-quality. There are a few realistic paths:

Prescription: hGH can be prescribed by a doctor in many countries for documented deficiency. This is the cleanest route if you can get it.
UGL Labs: Underground labs (UGLs) are the more accessible and affordable option for most people. Nearly every country has some way to access UGL-sourced hGH if you do the right digging in your local community. The catch is that UGL products are not subject to any pharmaceutical quality control: purity and actual dose vary, and contaminated batches do exist. The prescription route above is bioidentical and verifiable, so it is worth pursuing first. If you do go the UGL route, use a source that provides third-party purity testing and start at the lowest sensible dose.
Can’t access either? hGH is strongly preferred as the base, but if it is truly out of reach you can try CJC-1295 + Ipamorelin to stimulate and speed up your own pituitary’s awakening. These do not replace hGH, they only nudge your GH axis to wake back up, so treat them as an awakening aid rather than a full substitute.

If you have trouble finding what you need, I can help point you in the right direction.

Synergistic Peptides During Recovery

For certain people, the protocol has missing keys that no amount of fasting or hormones will unlock on their own. These three peptides address immune, gut, and energy axes that are commonly broken in chronic illness:

Thymalin (Thymic Peptide):A peptide derived from the thymus gland that directly stimulates immune system regeneration. Particularly valuable for people whose immune dysregulation is the core driver of their illness; it essentially “reboots” thymic output, which declines with age and chronic stress. Pairs powerfully with hGH’s tissue-rebuilding signal.

BPC-157 (Body Protection Compound):One of the most researched healing peptides available. Accelerates repair of the gut lining, tendons, nerves, and vascular tissue. For people with a damaged gut (leaky gut, SIBO, chronic inflammation), BPC-157 can be a critical bridge that allows nutrients to actually absorb during the rebuild phase. Also shows strong synergy with stem cell activity post-fast (see Refeeding page).

Retatrutide (GLP-1/GIP/Glucagon Triple Agonist):A newer triple-agonist peptide that activates glucagon signaling alongside GLP-1 and GIP. For people stuck in low-energy states with poor glucose utilization, the glucagon component can raise baseline energy availability in a way that nothing else does. Consider this for cases where fatigue persists despite normalized temperatures and adequate caloric intake.

Not everyone needs all three. Think of them as targeted keys for specific locks (immune, gut, and metabolic energy). Identify your weakest axis and start there.

The Final Step: Testosterone, After the Rebuild Is Underway

In my own recovery, testosterone was the last lever, not an early one. It goes in only after the earlier work is done: the fast has cleared the ground, T3 has restored metabolic power, and the hGH rebuild is already established. On that base, testosterone adds mitochondrial density and muscle and acts as the anabolic counterweight to the catabolic, high-cortisol state chronic illness leaves behind. Adding it before the prior cycles are complete is building density on an engine that is not yet running. This ordering is my clinical framework rather than a tested protocol.

How it is run:Case by case, only once prior cycles and blood work support it. Monitor hematocrit and hemoglobin (testosterone thickens the blood), and let estradiol rise rather than reflexively crushing it, since some of testosterone’s benefits run through the estradiol it converts into.

Medical caveat: testosterone is a prescription therapy with real cardiac, hematologic, and endocrine risks. Every dose and change is an individualized, physician-supervised decision, not a self-serve lever.

The Research Case for hGH in Chronic Illness

The published mechanism for why this matters specifically for chronic illness recovery: thymic regeneration, immune restoration, mitochondrial biogenesis, and tissue repair under conditions of long-term suppression.

Why hGH Works for Chronic Illness: The Research Case

If you have been sick for years, you are not just dealing with a pathogen or an immune glitch: your body has physically degraded. Muscle wasted. Immune tissue atrophied. The thymus, which produces your T-cells, has shrunk. No amount of fasting or antivirals rebuilds that. hGH does.

Thymus Regeneration & Immune Rebuilding:Clinical research, including the TRIIM trial, has demonstrated that hGH can physically regenerate the thymus gland, replacing fat tissue with functional immune tissue and increasing the production of “naive” T-cells (the immune cells your body uses to recognize new threats). These are the same cells that chronic illness depletes. Some studies show epigenetic aging reversal still detectable six months after stopping treatment, and increased T-cell output lasting up to a year post-discontinuation.

hGH vs. secretagogues:hGH is the preferred base. It is the actual hormone, so it needs nothing from your body to work, puts the least strain on the system, and gives the most benefit: strong muscle and tissue rebuilding, pronounced thymic regeneration, and a direct anabolic signal to every cell. Secretagogues like CJC-1295 + Ipamorelin only prompt your own pituitary to release GH, so they depend on your axis responding and do not replace hGH. I keep them for one narrow job: helping to wake up and speed the pituitary’s own recovery.

Safety & Immunogenicity:Modern recombinant hGH is bioidentical to what your pituitary produces. As a result, the immune system rarely recognizes it as foreign, with antibody formation rates in adults of approximately 2 to 3%, far lower than many common medications. Peptide secretagogues, by comparison, can provoke antibody responses against the peptide (usually without clinical impact), one more reason hGH stays the base. For most people, well-sourced recombinant hGH is remarkably well tolerated.

The Bottom Line:You are already doing the hardest part by dry fasting and committing to this protocol. hGH is not a shortcut; it is the targeted rebuilding signal that tells your body to use everything the fast liberated. Stem cells mobilized. Immune system primed. The only thing left is giving your body the hormonal instruction to rebuild. That is what hGH provides.

Can't source real hGH or peptides?

This is the wall almost everyone hits. No doctor will prescribe slow-release T3, and the peptide and hGH markets are full of fakes. Inside 1-on-1 coaching you get my current, personally verified supplier contacts for slow-release T3, peptides, hGH, and cyproheptadine, plus exactly what to order and how to dose it. Most people say that list alone was worth the price.
