We’re all looking for an edge. Whether in our businesses, our finances, or yes, even in the gym. That means looking at the latest supplements and training tips from the people who know.

We’ve been reading a lot about the steroid Ostarine, and so we decided to write up a review. During our research, we did find that the FDA considers anything with Ostarine in it to be illegal. To give our readers the best information, we decided to include in this review the best legal alternative we found to Ostarine, OSTABULK, from Brutal Force.

What is Ostarine?

Ostarine was developed by pharmaceutical company Merck, and it has been in clinical trials for over a decade. The trials and development are for people with wasting diseases, to help them build and retain healthy body weight.

The drug is also known as Enobosarm, and it is not legal in any known countries. It is important to note that, as you may find it in unlabeled ‘gym supplements.’ It is regulated by the United States Anti-Doping Agency, as well as other drug regulating bodies.

The science behind Ostarine is similar to other steroids. It bonds to receptors in the cells that tell it to promote growth in the body, mimicking the natural hormones we all have during pubescence. Ostarine is generally taken orally as a post-workout supplement. However, it has not yet even made it out of clinical trials: the developers of Ostarine have not yet found it effective enough to take to the normal market.

Ostabulk: Natural Alternative
  • Legal alternative to Ostarine
  • Mimics muscle-building benefits
  • All natural ingredients = no side effects
  • No need for prescription
  • Fast-acting & powerful formula 


Other than the very real legal issues you could face when taking banned and illegal substances, there are significant health risks involved with Ostarine. We relied on a number of articles, but study from the National Institutes of Health was especially insightful.

In it, they found that 13% of participants in the study showed signs of something called “Malignant neoplasm progression,” which is cancerous. Also, a number of participants reported symptoms that resemble the side effects of chemotherapy. Another source we found reported liver damage, headaches, and nausea from Ostarine use.

The Alternative

While researching the steroid Ostarine, we did find several legal alternatives. Several of them were safe, and a few were even effective. The one we believe offers the best results in a safe and legal package was Ostabulk, from Brutal Force.

The primary ingredient we keyed in on with Ostabulk is something called D-Aspartic acid. It’s an amino acid that we’ve reviewed as part of some testosterone boosters on the market.

D-Aspartic acid has been shown to increase the protein synthesis in muscles and promotes muscle growth and strength. Also, importantly as an alternative to Ostarine, even the aforementioned National Institutes of Health has noted that testosterone levels in mammals can be significantly increased with D-Aspartic acid, without the dangerous side effects associated with Ostarine.


While some supplements on the market call themselves testosterone boosters, many of them rely on snake oil recipes. Some supplements we’ve researched are cocktails of various over the counter herbs you can buy yourself and roll the dice.

Ostabulk is different, though. It uses clinically researched and proven ingredients in a blend that’s designed for results. And they boast a 98% customer satisfaction rate. That means people are using it, and hitting the strength and bulking goals they need.


D-Aspartic Acid: Like we mentioned above, this amino acid has been researched and it works. It promotes more of your body’s natural testosterone levels, safely. One key feature of using a supplement that increases your own production of a hormone is your body will stop producing it as soon as it reaches unsafe levels. That means you won’t be risking any adverse side effects by taking it.

Fenugreek and Nettle Extracts: Sometimes a little herbal lore has a ton of truth. St. John’s Wart, for example, had been used for centuries, and then later found to actually contain a natural form of aspirin. Fenugreek and stinging nettle have both been recently found to promote the amount of testosterone produced in the body and how much bonded to cells for protein synthesis.

Korean Red Ginseng: Used for centuries in East Asia as a male supplement for health, this herb is included here to help with overall hormone health and production.

Magnesium, Zinc, and Boron: Not only are these essential minerals that we don’t see nearly enough of in our modern diets, all three of these minerals are necessary for the synthesis and use of acetylcholine, which is the primary compound responsible for the transmission of signal between nerves and muscles. It wouldn’t matter how much testosterone you had if you didn’t have the necessary chemicals to fire the muscles themselves.

Vitamins B6, K1, and D3: Like the minerals mentioned above, these three vitamins get left out of modern food production. That’s because they’re mostly for muscle gain, muscle tone, and proper metabolism. And those things don’t seem to be the goals of snack food companies. By including them in Ostabulk, Brutal Force makes sure that as you’re adding muscle and building new strength, you’re also getting the nutrients you need to keep your gains.

Bioperine®: This is a trademarked form of the natural piperine, from the black peppercorn. Piperine has been proven to help the body with what’s called macronutrient absorption. By now we’ve all read that you can take 5 million grams of Vitamin C and pass all of it away in urination. With Bioperine, you’re going to absorb all of the key ingredients in Ostabulk, and make them available for your body.

Does it Work?

Every ingredient we researched in Ostabulk has a history of clinical and anecdotal success. That means these ingredients have been working in the lab, and in the gym. And Brutal Force sports a Five Star rating from over 1,000 reviews.

Maybe more impressive, 9 out of 10 Brutal Force customers recommend their products to their friends. We all know you don’t tell anyone about what you’re using unless it works.

The best part for you, Brutal Force offers a 100-day money-back guarantee for all its products. So you can try it out for over three months and test it risk free.

Side Effects

There have been no side effects reported or known from use of Ostabulk, unlike the dangerous Ostarine steroid. That means you can use it and feel safe. It also means you can stack it with your other favorite supplements.

And because it’s completely legal, you don’t need to worry about tripping any drug tests, or any contraindications with medications from your doctor.

Pros and Cons


  • Effective alternative to Ostarine.
  • Safe and totally legal.
  • Available without a prescription.
  • Proven testosterone boosting ingredients.

  • Better muscle gains, strength, and drive


  • Only available through the Brutal Force official website.
  • Because D-Aspartic acid is proven to boost testosterone, it may not be suitable for all athletes.


While we did our due diligence with Ostarine, we did find it was illegal. We also found that it doesn’t have a true lineage of effectiveness. Combined with its known adverse health effects, we found that use of Ostarine wasn’t worth the risks.

During our research, though, we did find Ostabulk was a legal and safe alternative with proven ingredients. So if you’re looking for bigger strength gains, better muscle tone and mass, and increased energy and performance in the gym, we recommend Ostabulk.

It’s available on the Brutal Force website for $59.99 for a one month supply. If you buy in bulk, though, you can get a third month free after purchasing two months worth. And they do have that 100-day money-back guarantee.
