Ostarine Review Of 2022: What Are The Results & Dosage?


How conversant are you with Ostarine MK 2866? Fret not if you aren’t well informed because you will learn about it in this Ostarine review extensively. Ostarine MK 2866 is a nonsteroidal selective androgen receptor modulator (SARM) in liquid form. Most bodybuilders use it to shred fat and increase lean muscle mass. However, it was developed for patients to gain weight mass when suffering from cancer muscle wasting diseases like cachexia.

We have independently compiled this comprehensive Ostarine-MK 2866 review to help you should you intend to use this compound in bodybuilding. We have included how it works, the proper doses, usage, the result you should expect, and side effects. In addition, we have included a legal alternative to this SARM. Read this review to the end to learn more about this for better results. But firstly, let’s expound on SARMs.

What Is A SARM?

This class of therapeutic compounds modulates the behavior of your androgen receptors by triggering your DNA, resulting in faster muscle development. Unlike steroids, SARMs don’t affect the non-skeletal muscle tissue. This feature makes it effective in increasing lean body mass.

The results from the use of Ostarine MK 2866 to increase muscle mass showed remarkably fast with fewer side effects than anabolic steroids, although this isn’t clinically proven.

James T. Dalton and Miller accidentally discovered the first nonsteroidal SARM in the 1990s. They intended to use it as androgenic drugs like the anabolic-androgenic steroids. Ostarine’s effect on muscle growth was exceptional, driving the scientists to concentrate on it. However, as time went by, its effects quickly gained attention from bodybuilding dietary supplement manufacturers. The bodybuilders have been illegally using the SARMs, with Ostarine MK 2866  being the common one. So, what exactly is Ostarine MK 2866?

Ostarine MK 2866: Brand Overview 

Ostarine MK 2866 is an artificial muscle strengthening compound found in some dietary supplements used in bodybuilding. Developed by GTx, Inc., this compound is classified in the category of SARMs due to the result of Dalton’s years-long work refining the SARM he discovered. Ostarine, also known as Endobosarm, went into the clinical trial. However, despite the ability to grow lean muscle, it couldn’t help with its intended use in treating cancer and muscle-wasting diseases.

Nevertheless, the company considered it a success and spent more on its development. The preliminary results were encouraging until 2013 when Ostarine  MK 2866 failed in two trial phases. The final nail to its proverbial coffin came in 2018 when it failed in the ASTRID pilot phase. However, some studies showed that it might help treat stress urinary incontinence in affected women. Unfortunately,  the FDA eventually issued a warning against human use after later studies. But why do sports enthusiasts and bodybuilders love Ostarine MK 2866?

  • Rise in Popularity

Ostarine MK 2866’s popularity rose through word of mouth in the bodybuilding world since it was a better option for lean muscle gain. Those who used Ostarine MK 2866 believed it was a better alternative to anabolic steroids in muscle building. However, subsequent numerous clinical trials proved otherwise. Nevertheless, Ostarine’s popularity is still soaring thanks to the internet and its availability in the form of supplements. Ostarine is now available through many sources, unlike in the beginning, mainly due to substance sale and legal gray areas. 

  • Ostarine MK 2866 Legality

The FDA classifies Ostarine MK 2866 and other SAEMs as investigational drugs. The classification means that it’s legal to sell and buy it in the U.S and many parts of the world for research purposes. However, note that selling it for human usage is illegal, including products that use Ostarine as an ingredient.

This law makes it possible to buy Ostarine MK 2866 for research purposes and use it according to preference. For example, many bodybuilding enthusiasts purchase Ostarine for use in building muscles and cutting. However, it would be best to take caution to avoid overdosing. This is because they don’t sell this SARM over the counter, and you can’t get a prescription for it. Furthermore, no qualified medical practitioner can assist you in determining the proper dosage due to the risk of losing their practicing license.

Ostarine MK 2866 is a banned substance, and you should sell or buy it for human consumption. This product is banned by the World Anti-Doping Agency (WADA) and USA Anti-Doping Agency (USADA) due to the substance’s ability to enhance performance.

How Do Ostarine MK 2866 Work?

Ostarine MK 2866 works by connecting to androgen receptors in a tissue-selective manner, differentiating it from anabolic steroids. The receptors detonate to grow muscles faster and enhance protein synthesis that helps with building muscles. This mechanism is similar to anabolism, where small molecules are divided into more complex ones. Note that these processes need a lot of energy. Ostarine MK 2866 acts as the external force that enables you to attain lean muscles with a consistent and intensive workout.

In addition, Ostarine MK 2866  boosts endurance levels that enable a long and intensive workout. This feature comes in handy if fatigue kicks in due to the fat-burning diet, as it improves your recovery time.  

What Are the Results Achievable With Ostarine MK 2866?

There is enough visual evidence that Ostarine MK 2688 can help with burning body fat and gaining body mass. However, there are no clinical trials on bodybuilders, making the results uncertain. The only human trials are on patients’ muscle-wasting health conditions. It is safe to say that, like other SARMs, Ostarine is like steroids in the body.

In addition, Ostarine MK  2866 has shown promising results in bettering symptoms of urinary incontinence and breast cancer. However, there is less evidence, and the results are still open for further research. But as a bodybuilding enthusiast, what result can you get from Ostarine MK 2866?

 What Can You Expect From Ostarine MK 2866?

On the other hand, Ostarine MK 2688 gives results faster. So you should expect a quicker return on investment, with the following typical results:

  • Increased muscle mass

In line with its intended use, Ostarine MK 2688 helps with conditions like muscular dystrophy since it combines with androgen receptors. But in the absence of such health conditions, it attaches itself to the receptors and accelerates your body’s metabolic rate to help in increasing muscle mass. Once the attachment occurs, the SARM triggers the protein to enhance protein synthesis and grow muscles faster.

  • Improved recovery

Ostarine has also shown promising results in improving body and muscle recovery. The recovery happens when this substance and receptors meet. This makes it possible to train regularly to achieve lean muscles.

  • Regulates body fat levels

Ostarine MK MK 2688 can maintain both mass and muscle strength during caloric deficits. In addition, it also has the nutrient partitioning effect, which enhances fat loss when on the Ostarine cycle. Therefore, Ostarine MK 20866 is better than other SARMs like LGD-4033 Ligandrol and S.R.- 9009 Stenabolic for beginners. 

  • Increased bone density

This SARM also showed a positive effect on preliminary bone healing in rats. The results are due to an increase in Serum levels of phosphorus after Ostarine treatment. This result indicates that Ostarine can help improve microstructural bone indices, which results in stronger bones.

Usage, Doses, and Cycling of Ostarine MK 2866

As we mentioned earlier, no qualified doctor can help you with directions on how to take MK 2866. For that reason, we have scoured the internet and come up with the right way to use SARMs safely. 

Who is Ostarine MK 2866 suitable for?

Ostarine is suitable for patients suffering from muscle wasting syndrome due to autoimmune disorders and cancer. However, its properties have made bodybuilding enthusiasts use it to cut body fats, boost muscle growth, and get lean body mass faster. Note that this application requires caution when cycling.

What is the Right Ostarine Dosage?

You first need to consider different ages and underlying health conditions to get the proper Ostarine dosage. But in general, you should start with 20 mg if you are bulking and 10 to 15 mg if you want to lose body fat. This is commonly known as cutting. You should take 10 mg as the minimum and 30 mg as the maximum per day. However, if you are a lady, it will be best to use 5mg for a start. There is no standard dosage, although it’s best to start with 10 mg and gradually increase as you get used to it.

Many users prefer to try what works best for them for a few weeks of cycling. However, this exposes you to dangers that come with trial and error. Our research shows that you don’t require an excessive amount to realize notable results. The information we found on user forums shows that a typical Ostarine MK 2866 cycle consists of weeks one to six of 10 to 20 mg. This is the cycle for new users. Experienced users can go with 20 to 30 mg. All these cycles are followed by post cycle therapy (PCT) to help restore your testosterone levels.  

When Should You Take Ostarine MK 2866?

For effectiveness, it’s best to use 24-hour intervals when on the Ostarine cycle. You can take it at any time of the day, provided you maintain the break as mentioned earlier. Although for consistency and best results, you should take it in the morning or after your workout. Ostarine MK 2866 has a 24-hour half-life, making it pointless to take it multiple times per day. In addition, you should avoid taking this SARM during or right before you start working out.

 Stacking Ostarine MK 2866 for bodybuilding

Stacking is essential since Ostarine causes severe testosterone hormone suppression. While at it, you need to apply for a PCT program. Some stacks are suitable for cutting, increasing lean muscle mass. Some of the SARMs you can stack with Ostarine MK 2866 include:

 Ligandrol (LGD 4033)

This stack is a simple stack that includes Ligandrol and Ostarine, which makes it suitable for bulking. Its cycle lasts eight weeks, but the dosage changes after the first week. For instance, you will take 10 mg of Ostarine MK 2866 daily in the first week and then increase the dosage to 20 mg for the remaining seven weeks. Meanwhile, you will also be taking 5 mg of LGD 4033 per day in the first week. Then, you can increase the dosage to 10 mg for the subsequent weeks. But note that you need a four-week PCT after completing your cycle. 


Cardine and Ostarine stack is best for cutting. The cycle for this stack also lasts for eight weeks and consists of 20 mg of Ostarine daily and 10 to 20 mg of Cardine. This stack also requires a four-week PCT.

Cardine and Andarine

This stack comprises two more selective androgen receptor modulators and is more advanced than those mentioned above. It entails consuming 20 mg of Ostarine MK 2866 for the entire cycle and around 10 to 20 mg of Cardine daily. For Andarine, you will have to take 25 mg to 50 mg daily, followed by the four-week PCT to undo the effects of the substances. 

Stacking for female bodybuilders

Female bodybuilders should use the Ostarine MK 2866 and Andarine stack, but dividing the quantity in half is essential to achieve the intended muscle mass. This stack only lasts six weeks. You will not need post-cycle therapy after using it because of the dose’s lowness.

What Are the Potential Side Effects of Ostarine MK 2866?

Despite Ostarine MK 2866 being considered safe compared to anabolic steroids for growing muscle mass, prolonged use can potentially affect you. Some of the side effects come due to its selective action. Most of these side effects appear after the cycle, with a bit more in females appearing during the cycle. The most common side effects include:

  • Testosterone suppression
  • Joint pain that calls for a break until the pain subsides.
  •  Severe headache
  •  Disrupted menstrual cycle
  •  Liver toxicity
  • Hair loss
  •  Heart attack
  • Sleep disorder
  • Stroke
  •  Back acne
  •  Facial hair in menopausal women

So, which way to go if you want to safely and legally use SARMs in your bodybuilding? It will be best to use the legal alternative to Ostarine MK 2866. 

 Legal Alternatives to Ostarine MK 2866

There are legal alternatives to supplements, which are much safer and easily accessible. Unlike anabolic steroids and illegal SARMs, these compounds are minerals, vitamins, and plant extracts. They, however, work the same as the chemicals above in helping you build muscle faster and cut body fat. Although, it is best to note that an Ostarine MK 2877 alternative won’t be as strong. OSTABULK by Brutal Force is the most highly rated product in this category of legal options. So, what is it, and how does it work?

 Overview of OSTABULK

OSTABULK is a supplement scientifically developed by Brutal Force, a bodybuilding brand owned by a United Kingdom-based company called Health Nutrition Limited. This company specializes in workout aids for cutting body fat and building muscle mass. It also has a branch in the U.S where it manufactures, packs, and sells it. Unlike the anabolic steroids and SARMs, OSTABULK is FDA approved and fit for human consumption. Furthermore, it has no flagging from the world’s anti-doping agencies.

OSTABULK’s safety can be attributed to its 100% natural ingredients that duplicate the effects of testosterone to encourage muscle growth. Those ingredients include:

  • B6 vitamin
  • Magnesium
  • D3 (Calcium iodide)
  • Citrate of Zinc
  • K1 vitamin
  • D- Aspartic Acid (DAA)
  • Citrate of Boron
  • Fenugreek seed extract
  • Extracts of Korean Red Ginseng Root
  • Stinging Nettle leaf 

How Does OSTABULK Work?

OSTABULK works by stimulating the hormonal response of your testosterone. This compound is suitable for men since it’s intended to boost muscle strength. Its similarity to Ostarine MK 2866 is how it duplicates the testosterones effects to help you reduce body fat levels, boost energy, and increase lean muscle mass. However, its difference from Ostarine makes it essential to combine the supplement with a balanced diet and consistent workout to achieve the desired result. 

 What to Expect from Using OSTABULK?

Since OSTABULK works like Ostarine, you will get the same result, less the severe side effects of the banned selective androgen receptor modulator. You can notice the result within a few weeks after you start cycling. Some of the results include muscle gain, enhanced strength, and a ripped physique. OSTABULK also improves your endurance to work out for the results mentioned earlier. 

Usage, Dosage, Cycling, and Stacking of OSTABULK

You will purchase OSTABULK in capsule form with a bottle containing  90 capsules. It’s recommended to take three tablets per day which translates to an entire month’s supply. Note that it’s best to take the capsules with 8 oz of water 45 minutes before your first meal for it to work. In addition, you should take it on both your workout and non-workout days. Refer to Brutal Force’s official website for complete information on dosage and food.

It is safe to say that OSTABULK is the best supplement to increase muscle mass. This is because it’s 100% legal and natural to buy and ship worldwide. In addition, it involves no injection or liquid since it’s taken orally and doesn’t cause any hormonal imbalance. Therefore, this is your best bet to build muscle mass fast.

  • Who Should Refrain from OSTABULK?

OSTABULK is unsuitable for pregnant and breastfeeding women. In addition, those under 18 years old and people with underlying medical conditions can’t use it. However, the latter can consult a doctor. 

  • Stacking OSTABULK

You don’t need to stack  OSTABULK since it combines various natural supplements. However, if you feel you have to do it, you can try adding other safe and natural supplements using trial and error. Alternatively, you can go for Brutal Force’s stacks. The stacks that feature this supplement include Ironbound Building Stack and the Goliath Strength stack. 

What Are the Possible Side Effects of OSTABULK?

There are no significant side effects of using OSTABULK to grow muscle mass except for allergic reactions. This is because the product doesn’t attach to androgen receptors made in a facility that processes eggs, wheat, fish, milk, and soy. Unfortunately, it also contains the extracts we mentioned earlier, which can potentially cause an allergic reaction.

Some of the minor side effects you might experience while muscle building using OSTABULK include but are not limited to fatigue, nausea, and headaches. It is best to stop cycling and consult your physician if this happens.

Where Can You Buy OSTABULK, and What Are the Guarantees?

OSTABULK is only sold through the company’s official website. This strict measure is to control counterfeits and enhance the product’s credibility. So, you should know that any similar product sold on online marketplaces is fake. In addition, the company usually has offers on bulk purchases that don’t necessarily limit you to one product. However, note that the offers are generally scarce, and you should grab them as soon as possible.

Brutal Force trusts its products in muscle building and has a 100-day return policy with a 100% money-back guarantee. However, note that the guarantee doesn’t apply for single-item transactions or a single bottle. Additionally, to qualify, the package must be in its mint condition.

Conclusion – Does Ostarine Help Increase Muscle Mass?

The rise in the popularity of dietary supplements to increase muscle mass has led many bodybuilders and athletes to take illegal selective androgen receptor modulators. Unfortunately, some manufacturers don’t disclose the side effects of some of those products on a user’s body once they attach to androgen receptors, which makes them dangerous. We have covered the proper Ostarine dosage, cycle, and how to stack to mitigate the adverse effects of overdosing.

This Ostarine review has also covered OSTABULK—the legal alternative to Ostarine MK 2866. In addition, we have mentioned where you can buy a genuine OSTABULK from Brutal Force and the guarantees. It will help if you use the information in this review to start using these supplements safely for a ripped physique.
