Human Growth Hormone (HGH) is a key player in your body’s health, influencing everything from muscle growth and metabolism to recovery and aging. As we get older, our natural production declines. Many people are looking for ways to get those levels back up. This guide provides a detailed look at how to increase growth hormone, covering natural strategies, peptide therapies, and medically supervised treatments available in 2026. Whether you want to optimize your body's own production or explore advanced options with a doctor, we'll walk you through the steps.
To begin optimizing your growth hormone levels, you won't need a complex lab setup, but you will need a few key things:
Before diving into specific methods, it's crucial to understand the three main approaches to increasing growth hormone. Each works differently and is appropriate for different situations.

You can't optimize what you don't measure. The first step is to understand your current growth hormone status. Doctors don't typically measure GH directly because its levels fluctuate wildly throughout the day. Instead, they measure Insulin-like Growth Factor 1 (IGF-1).
IGF-1 is produced by the liver in response to GH and its levels remain stable, making it a reliable indicator of your average growth hormone production. Ask your doctor for a blood test to check your IGF-1 and other relevant hormone levels. This provides a crucial baseline to track your progress. It also helps your doctor determine if you have a clinical deficiency that may require medical treatment. While you can order an at-home testosterone testing kit, a full hormone panel including IGF-1 is best done through a provider. Understanding your baseline is the first move in taking control of your human growth hormone levels.
Your body releases the largest pulse of growth hormone during deep sleep (stages 3 and 4). Without quality sleep, other optimization efforts will have limited effect. The updated 2026 protocol for natural GH improvement specifically emphasizes deep sleep quality over total hours slept (Growth Hormone Optimization Naturally: Protocol 2026).
How to do it:
Studies on peptides like Ipamorelin have shown a 23-31% increase in deep sleep, highlighting how critical this sleep stage is for GH release (Ipamorelin Complete Guide: Growth Hormone Peptide Therapy).
Short, intense bursts of exercise are a powerful natural stimulus for GH release. High-intensity resistance training (HIRT) and high-intensity interval training (HIIT) are particularly effective. These workouts create a significant metabolic stress that signals the pituitary gland to release GH to aid in recovery and tissue repair.
One source highlights that high-intensity workouts can temporarily but significantly increase HGH production (How to Increase Growth Hormone Naturally: 7 Proven Methods). The key is intensity. A casual walk won't do it. You need to push your body hard for a short period.
How to do it:
Fasting is one of the most effective ways to naturally boost growth hormone. When you fast, your insulin levels drop. Low insulin is a key signal for your body to ramp up GH production. One study noted that HGH levels can increase by 300% after three days of fasting and by as much as 1,250% after one week (Human Growth Hormone: 13 Ways to Increase HGH Naturally).
For most people, prolonged fasts are not practical. A more sustainable approach is daily time-restricted eating, like the 16:8 method (fasting for 16 hours and eating within an 8-hour window). The 2026 GH protocol emphasizes timing these fasting windows around insulin clearance rates for maximum effect (Growth Hormone Optimization Naturally: Protocol 2026).
How to do it:
If natural methods aren't enough, peptide therapy is the next logical step for many. Growth hormone secretagogues (GHSs) are peptides that signal your pituitary gland to produce and release more of your own GH. They work with your body's endocrine system, maintaining the natural, pulsatile rhythm of GH release (Growth Hormone Secretagogues: Complete Guide).
The most common combination is a GHRH analog (like Sermorelin or CJC-1295) with a GHRP (like Ipamorelin). This combination creates a synergistic effect, increasing GH peaks 3-5 times more than either peptide alone.

For individuals with a confirmed Adult Growth Hormone Deficiency (aGHD), direct replacement with recombinant human growth hormone (rhGH) is the standard of care. Brands like GENOTROPIN, NORDITROPIN, and HUMATROPE are all forms of somatropin, which is bioidentical to the GH your body produces.
This is a prescription-only treatment and requires a doctor's diagnosis. A significant development is the recent study on somatrogon, a once-weekly long-acting growth hormone. A March 2026 study found it effective at improving body composition in aGHD adults and could improve adherence by reducing injection frequency from daily to weekly (Efficacy and safety of once-weekly somatrogon in adults with growth hormone deficiency | Pituitary | Springer Nature Link).
Dosing and Cost:
Beyond the core steps, several other supplements and lifestyle factors can support your efforts to increase growth hormone.
When trying to increase growth hormone, many people make predictable errors that hinder their progress. Avoid these common pitfalls:
It's essential to involve a healthcare professional in this process. Contact your doctor if:

What is the best natural way to increase growth hormone? The most effective natural methods are a combination of high-intensity resistance training, getting consistent deep sleep, and implementing intermittent fasting to keep insulin levels low. No single method works in isolation; a combined approach is best.
Are HGH peptides legal in 2026? As of April 2026, many growth hormone secretagogue peptides like CJC-1295, Ipamorelin, and Sermorelin are legally available by prescription from licensed U.S. compounding pharmacies for specific patient use. While their regulatory status has been debated, with some temporarily moved to the FDA's restricted Category 2 list, they remain compoundable under current guidance (Peptide Therapy Statistics 2026: The Definitive Data Roundup).
How long does it take to see results from increasing HGH? With peptide therapy or HGH injections, many people report improved sleep and recovery within the first few weeks. Noticeable changes in body composition, such as increased muscle mass and reduced body fat, typically take 2-3 months of consistent use. Natural methods may take longer to show physical results.
Can you increase growth hormone after 40? Yes. While natural GH production declines with age, the methods described in this guide are effective for adults of all ages. Both lifestyle interventions and therapies like peptides can significantly increase GH production and IGF-1 levels in individuals over 40.
What foods increase growth hormone? No single food directly contains or creates HGH. However, foods rich in amino acids like arginine and glutamine (e.g., meat, fish, dairy, spinach) may support GH production. The most important dietary strategy is to avoid foods that spike insulin, especially sugar and refined carbohydrates.
