The 6 Best SARMS for Cutting, Bulking & Stacking In 2021

6 Best SARMS (md 18)

What Are SARMs?

Selective androgen receptor modulators, or SARMs, are a group of investigational compounds. Investigational because they are still being researched and studied for their potential uses.

SARMs have gotten a lot of attention because they have a unique mechanism. They bind to the androgen receptors differently than compounds such as anabolics, meaning they are said to cause fewer adverse effects (1).

Many of these SARMs have shown promising effects in clinical research. These effects include accelerated muscle growth, improved performance, and faster recovery.

Because of these benefits, bodybuilders and other athletes have started researching these compounds.

This article will go over the best SARMs for both bulking and cutting and the potent effects they carry with them.

Are you simply looking for the best, most reliable vendor for these compounds? Then, check out Science.bio!

The Best SARMs For Cutting

Since there are different types of SARMs, we've decided to split them into two categories; cutting and bulking compounds - let's check them out.

#1. Ostarine (MK-2866)

After thoroughly researching the various compounds, we've concluded that the best SARM for cutting is Ostarine (MK-2866).

According to user experiences, it is mainly known for:

  • Speeding up lean muscle growth
  • Preserving muscle tissue while cutting
  • Accelerating the muscle recovery process
  • It helps repair injuries faster

It possesses many benefits that can come to use during a cutting phase. For optimal effects and results, users advise taking 20mg per day for 6 to 12 weeks.

This cycle has to be followed by a 4-week post cycle therapy. For this, you can use Rebirth PCT as it is the best PCT supplement after any SARMs cycle.

Ostarine is also one of the SARMs with the most clinical research available. It's also been through human clinical trials with promising results.

#2. Andarine (S4)

Another compound that is considered to be one of the best SARMs for cutting is Andarine or S4.

Due to its unique effects, many users choose to use it specifically for cutting and getting lean. It's important to note that this is said to be slightly stronger than our first option.

Here's what users had to say about Andarine:

  • It packs on muscle mass extremely fast
  • It has muscle-hardening effects
  • Maintains muscle and strength during a cut
  • It makes muscles appear fuller and more vascular

To get the most out of it during the cutting period, user experiences recommend running it at 50 to 75mg per day for 6-8 weeks.

This SARM also suppresses testosterone, meaning post cycle therapy is inevitable. Use Rebirth for four weeks after the cycle to recover.

#3. Cardarine (GW-501516)

Technically, the following compound on our list is not a SARM but is often marketed as one. It's actually a PPAR Agonist, meaning it has a different mechanism.

Cardarine or GW-501516 is something we had to include, as it is often stacked with the compounds mentioned above.

When we asked those that have researched With Cardarine why it is so valuable, they pointed out the following:

  • It significantly increases stamina and endurance
  • Helps accelerate fat loss
  • Could also boost exercise capacity

As you can see, it comes with many useful effects that shine during the cutting phase. It's recommended for optimal results to take 10 to 20mg per day for 6 to 8 weeks.

More stamina, endurance, and accelerated weight loss are the benefits you should be looking for when getting lean.

Purchase Cardarine (GW-501516) from our recommended source.

Best SARMs Stack For Cutting

We've gone over each of the best SARMs for cutting. They each have their own unique set of benefits, and because of this, many users have started stacking SARMs together.

When these compounds are stacked together, it creates a synergetic effect as they boost each other's effects. For example, Ostarine is excellent at preserving muscle mass, whereas Cardarine works great for promoting fat loss.

When stacked together, you can lose fat faster AND hold onto the muscle mass you've got, pretty much a win-win scenario.

The Best SARMs Stack for cutting is the Triple Stack, a combination of Ostarine, Andarine, and Cardarine. Generally, the Triple Stack is used anywhere from 4 to 8 weeks at the following dosages:

  • Ostarine 10-20mg/day
  • Andarine 50-75mg/day
  • Cardarine 10-20mg/day

Since stacking them causes additional suppression, post cycle therapy is an absolute must as your hormones will need help to recover.

You'll need to use Rebirth PCT for a minimum of 4 weeks, preferably 8. You can find Rebirth by clicking here.

When these three are combined, you'll have the most potent stack for cutting on hands. Unfortunately, companies don't sell stacks, meaning you'll have to buy these products separately.

You must get these SARMs from a trustworthy source. You can buy everything you need directly from Science.Bio - hands down the best vendor for these products.

The Best SARMs For Bulking

We are moving on to the best SARMs for bulking. The following three compounds are said to be the most potent compounds for packing on size and strength.

So let's check them out.

#1. RAD140 (Testolone)

If you're looking to bulk up and gain a lot of size, RAD140 is the SARM you're after. It also goes by the name Testolone, and it's incredibly potent at just small dosages.

After taking the time to read through many of the user experiences online, we've concluded that RAD140 is one of the best SARMs for bulking.

What can you expect from this compound? Here's a list of the benefits that come with using Testolone:

  • Extreme muscle mass gains (10-15lbs per cycle)
  • Quick strength and power increase
  • More exercise capacity during workouts
  • It helps your muscles recover faster

To significantly enhance a physique, most users are taking 10 to 20mg for the course of 6 to 8 weeks, depending on experience.

However, the power of this compound causes severe testosterone suppression. You can't run a cycle without following it with proper post cycle therapy.

As we've recommended earlier in this article, Rebirth for 4-8 weeks after a course of SARMs is what you need. Let's move on to the following bulking product.

#2. LGD4033 (Ligandrol)

Another excellent compound for bulking is LGD-4033 or Ligandrol. You've probably heard of it, as many users take this product to bulk up.

When compared to RAD140, it's slightly less potent but still delivers drastic results. We've gone through some of the reports found on various forums, and they've impressed us.

Here's what they said LGD4033 is capable of doing:

  • Pack on lean muscle mass (Average is 10lbs per cycle)
  • Get stronger and increase the weights during workouts
  • Better pumps and vascularity on cycle
  • It gets your muscles ready for the next training quicker

Ideally, most run Ligandrol at dosages of 5 to 10mg per day as it doesn't need much to show effects. However, those new to SARMs should consider a low dosage, as this will be enough to see results.

LGD4033 also calls for a PCT after the cycle has been finished. Even though it's seen as one of the best SARMs for bulking, it may come with some side effects.

#3. S-23

We've arrived at the last compound in our article, S-23. Less famous than the other SARMs for bulking on our list, but an extremely powerful one.

Even though there's not much research available on S-23, it hasn't stopped bodybuilders from experimenting with it to see what it has to offer.

Here's what some of them experienced during a cycle:

  • Explosive muscle and strength gains
  • Increased levels of aggression
  • More power during high-intensity workouts

Because of the hefty side effects it comes with, it's not a compound for beginners. Our research shows us that it's effective at dosages of just 10mg per day.

It's safe to say that S23 deserves its place on our list of best SARMs for bulking because it's so powerful. If you're considering research on this product, you'll need to know where to get it from.

We're massive fans of Science.bio, as they're known to provide the best quality SARMs, including S-23. You can click here to visit the product page.

Best SARMs Stack For Bulking

Experienced users can look into using a SARMs stack for bulking. Of course, there are various types of compounds you can combine into a stack.

But, we've found a significant amount of users go for a specific type of stack, which is said to be excellent for bulking. That SARMs bulking stack consists of RAD140, LGD4033, and MK-677.

The latter, MK-677 (Ibutamoren), isn't a SARM but said to be a great addition for enhancing recovery. It's definitely one to include if you are looking for the best bulking stack.

Users that have researched with this combination ran it at the following dosages:

  • Testolone 10-20mg per day
  • Ligandrol 5-10mg per day
  • Ibutamoren 10-30mg per day

This cycle generally lasts for 8 weeks. However, many point out that it takes a minimum of 1 to 2 weeks for everything to kick in at full force.

Vendors don't sell stacks, so you need to get each product individually from a trustworthy site. Buy your SARMs from Science.bio, as they're the only transparent company we fully trust.

Best PCT For SARMs

It's important to know that every cycle of SARMs, regardless of the type, requires post cycle therapy (PCT).

It's because they're suppressive, meaning they'll lower your body's testosterone levels. Then after the cycle is done, your body requires help to get them back up.

The best PCT for SARMs you can get is Rebirth, produced and sold by Huge Nutrition. It contains all the essential ingredients you're going to need to get your hormones back up and running.

It's made up of quality compounds that'll start working from day one, such as Arimistane, D-Aspartic Acid, and Tribulus.

Rebirth should be taken for at least four weeks as your SARMs PCT. It will help your endocrine system and get those testosterone levels back at an optimal level during this period.

That means it's going to help you maintain your muscle mass, strength, libido, performance, and energy.

You often see that those who don't use a post cycle therapy like Rebirth end up losing a massive amount of the gains they've gotten from a cycle.

We always recommend stocking up on two bottles, just in case you're going to need to run it for longer than four weeks due to heavy suppression.

Do You Need Cycle Support For SARMs?

Despite what many people say, SARMs are liver toxic. A lot think that's not the case, but it's true.

There have been several reports of liver injury caused by the use of selective androgen receptor modulators.

That means cycle support (organ support) is highly recommended when running a cycle. It's going to help support your organs while they're undergoing stress and tension caused by the cycle.

But, you're not going to want to get just any organ support; you need one that uses the right ingredients.

I've used probably a dozen of cycle support products throughout the years, but there's one that stood out.

I'm talking about Defend; it's by far the most effective and stacked cycle support you're going to find.

It's stacked with high-quality ingredients, here's a breakdown

  • Tauroursodeoxycholic acid (TUDCA)
  • N-Acetyl-Cysteine (NAC)
  • Milk Thistle (Sylibum marianum)
  • Peppermint Leaf Powder
  • Saw Palmetto Extract

Defend is sold exclusively by Huge Nutrition, the same company that sells the Rebirth PCT for SARMs. That means you're able to stock up both these products from their site.

Make sure to run Defend from the start to the finish of your cycle. So, for example, if it's a 12-week cycle, you're going to need to run it alongside for the entire 12 weeks.

The Best Place To Buy SARMs From

When searching the web, you'll come across several vendors that have SARMs for sale. We've gone through the most popular sources but found the majority to be lacking when it came to quality.

The only source we can comfortably recommend is Science.bio. As someone who has researched these compounds, we found all of the products they sell legit and accurately dosed.

Click here to be taken to the official Science.bio site to purchase third-party tested SARMs.

The reason why we stand behind them is that they have strict quality control. You can find all the third-party tests on their sites, showing you how pure the product is.

The higher the purity of a compound, the better. Everything Science.bio has it tested above 99% purity, which means you won't have to worry about your product being bunk or underdosed.

Buying SARMs from cheap and sketchy sources can lead to serious adverse effects, which you obviously want to avoid.

On top of that, they're also reasonably priced. Unfortunately, we see way too many vendors overprice their products, and most of them don't even have public third-party tests available.


We've shown you the best SARMs out there for cutting and bulking. There are many highly effective compounds for building lean mass, strength, and increasing performance.

But, it's important to note that they do come with side effects. The main issue is that these SARMs cause hormonal suppression, meaning a post cycle therapy is an absolute must.

Cycle support is also highly recommended since there's plenty of evidence that these compounds put the organs under a lot of tension.

We recommend getting Rebirth PCT for your post cycle therapy and Defend for your organ support. These are both sold by Huge Nutrition, meaning you can order everything in one go.

If you're still searching for a place to buy SARMs from, you should head over to Science.bio as they're the top-rated vendor right now.
