Phase 5: hGH Therapy (Rebuilding Your Body)

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

* Can’t get hGH? Real hGH is the strongest rebuilding signal, but it is not the only way in. Easier-to-source growth hormone secretagogues like CJC-1295 + Ipamorelin can be used in its place on a slightly modified protocol. Ask Yannick in the portal for the adjusted plan.

Stop Cyproheptadine Before Starting hGH

If you used cyproheptadine during your first T3 cycle (for appetite, sleep, or brain-gut calming), stop it before you move to hGH. Cyproheptadine directly lowers growth hormone output, so it belongs to the first T3 cycle only. It also blunts the nighttime cortisol pulse that hGH depends on to burn fat while you sleep. Running both at the same time works against the therapy. 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 we 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? Consider Tesamorelin, a GH secretagogue peptide. Rather than replacing hGH directly, it signals your pituitary to maximize its own production. Output is limited (typically below 2 IU) but it is legal, far easier to source, and still meaningfully effective for supporting the recovery phase.

If you have trouble finding what you need, Yannick 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 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. Tesamorelin:Tesamorelin is a milder alternative that stimulates your pituitary to release its own GH in a pulsatile, natural pattern, making it safer and easier to source, but limited (typically below 2 IU output) and more targeted toward visceral fat. hGH provides broader systemic effects: stronger muscle and tissue rebuilding, more pronounced thymic regeneration, and a direct anabolic signal to every cell in your body. For serious chronic illness recovery, hGH is the more powerful tool.

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 2–3%, far lower than many common medications. Tesamorelin, by comparison, triggers antibody formation in up to 50% of users (though usually without clinical impact). 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 Yannick’s 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.
