Human Growth Hormone Stimulators: Boost Your HGH Naturally

In this post, we are going to cover a list of 10 human growth hormone stimulators and go over some tips to stimulate more growth hormone.

Human growth hormone plays a key role in staying young, long past the time when you have finished growing.

This powerful hormone is produced in the pituitary gland, which is the master gland of your body.

HGH influences body composition and plays an important role in your metabolism. It first starts to decline around age 30, and after that, every year it decreases by 2 percent.

The goal is to keep your human growth hormone at optimal levels as you age, so you can keep your youthfulness for as long as possible.

The off-label use of human growth hormone has led to a multi-billion-dollar industry.

While many believe the best way to increase human growth hormone is through synthetic HGH injections, these are not only very expensive but also have many risks and require a doctor’s prescription.

Many safe alternatives will boost your human growth hormone naturally without visiting your doctor or using injections.

Exercise and supplements are a great way to produce more human growth hormone.

10 Human Growth Hormone Stimulators

Let’s have a look at some of the options that can naturally stimulate human growth hormone production.

1. Mucuna Pruriens

Mucuna Pruriens is a very powerful dopamine and testosterone booster that is backed by science.

Recent studies have shown it can also help to boost HGH production because it contains high levels of L-Dopa, which is a dopamine precursor scientifically shown to help the pituitary gland release more growth hormone.

The added benefit of taking a pure high-strength extract of Mucuna is that it promotes feelings of enjoyment and motivation due to the increase in Dopamine levels.

2. Glutamine

Louisiana State College of Medicine researchers gave their study subjects 2 grams of L-Glutamine that had been dissolved in a cola drink.

Just 90 minutes after consuming the glutamine-cola mix, HGH levels were increased significantly in the group.

Studies also show that glutamine supplements don’t just enable an athlete to avoid illness and stop the breakdown of muscle.

They can, in fact, also increase human growth hormone levels, boost glycogen storage, and hydrate muscle tissues – three elements that are essential in protein synthesis.

We recommend the brand Optimum Nutrition Glutamine Powder as the best choice of glutamine.

3. L-arginine

A few studies have shown that L-Arginine can significantly increase human growth hormone levels in the body.

Researchers in one study gave their subjects a mix of L-arginine and L-leucine, and their human growth hormone levels increased by a shocking 700 percent.

This Arginine & Citrulline Combo is a great way to increase growth hormone levels naturally.

4. L-Ornithine

Japanese researchers found that before a workout, if a man who weighed 80 kilograms consumed 8 grams of L-ornithine, a 300 percent increase in HGH production occurs.

Another study originating in Finland found no significant differences in HGH levels after their subjects were given 2 grams of L-Ornithine before their workout.

In a Polish study, the researchers gave their subjects 10 grams of L-Ornithine before a weight lifting session, and significant growth hormone increases were recorded in all subjects.

However, you can see that the research is very conflicting, and more studies need to be done.

5. L-Leucine

L-Leucine is highly effective when combined with L-arginine.

In fact, studies have seen a whopping 700 percent increase in human growth hormone levels when these two amino acids are combined.

These studies show how this just might be one of the best natural growth hormone boosters out there.

Many studies have shown that L-Leucine improves protein synthesis, which in turn helps build lean muscle mass and burn fat, clearly showing that L-Leucine is one of the best and most potent human growth hormone stimulators to take.

I use this Pure L-Leucine Powder from the company Bulk Supplements.

6. GaBA

GABA (Gamma-Butyric acid) is a neurotransmitter found primarily in your brain, which it gets from glutamine.

Studies have shown that GABA significantly increases human growth hormone levels post-training, and the men in this particular study had their HGH levels quadruple.

However, unless GABA is taken in mega doses, it is not that effective. The acids in the human gut effectively break down before they reach the brain.

7. Creatine

Creatine is one of the most studied supplements used by bodybuilders, and it’s also one of the most respected supplements out there.

Numerous studies are showing how creatine is an excellent human growth hormone stimulator, increasing HGH significantly, which is one of the reasons creatine works for muscle building.

Anyone who has done their research around bodybuilding supplements knows that most of the latest ‘hyped up products’ tend to fail in the first few years after their discovery.

On the other hand, creatine is one of those supplements that, year after year, has lived up to the hype surrounding it.

8. HIIT or High-Intensity Interval Training

In addition to fasting, high-intensity interval training has proven to significantly increase human growth hormone production.

The key is to maximize your heart rate using short, intense exercise bursts, which then lead to a major boost in human growth hormone levels.

In addition, when high-intensity interval training boosts human growth hormone levels, it activates the development of super-fast muscle fibers.

Once activated, these fibers will trigger a massive testosterone release along with a huge release of human growth hormone into the bloodstream.

9. Eat Whey Protein During Exercise Recovery to Boost Human Growth Hormone

Research clearly shows that using whey protein alongside resistance training will significantly increase Human Growth Hormone.

Your production of human growth hormone will increase by a whopping 771 percent during your high-intensity interval workout because you stimulate the fast-twitch muscle fibers.

These muscle fibers are seldom used with most other types of exercise. The higher your human growth hormone levels, the healthier and stronger you are.

Subjects in a study who took whey protein after running on a treadmill for 90 minutes had a heightened HGH response after performing an additional 2nd bout of intensive exercise.

However, you want to be very careful when choosing a quality whey protein, as there is a lot of whey out there that is denatured and filled with coloring agents and nasty sweeteners like aspartame.

To make sure you are getting a good whey protein, you want to check that it’s free from fillers, completely undenatured, and grass-fed like this Whey Protein.

10. A Sleep Mask

You can release increased amounts of human growth hormone while you sleep. Most of this release comes during REM sleep.

Using a sleep mask to block light will allow melatonin (the sleep hormone) to surge, resulting in a deeper, longer, more restful sleep.

More importantly, you will reach REM sleep, and therefore more HGH will be released.

With a sleep mask, look for one that does not put pressure on your eyes and is contoured to provide comfort for REM sleep, such as this one from Plemo.

If you have trouble sleeping, you can also try a melatonin supplement.
