SARMs or Selective Androgen Receptor Modulators have become increasingly common in the bodybuilding and recreationally lifting world.

But much like driving with your drunk Uncle Larry, there are safety concerns. Some use these research chemicals to enhance muscle mass, athletic performance, or even fat loss. But how safe are they exactly?

SARMs were originally developed to replace Anabolic Steroids in the medical world, as they do have fewer androgenic adverse effects. This doesn’t mean they are “good”, however.

We’re going to take a deep dive into the 5 Safest SARMs and the most potent SARMs, and see why these cannot be coined as “for human consumption”.

What Are the Safest SARMs?

SARMs were created in the late 1990s as a way to replace anabolic steroids in the medical field. Steroids had their uses, especially for treating muscle-wasting diseases like HIV/AIDS.

But, here’s the thing—steroids came with a lot of baggage. They caused some serious side effects, especially in women and kids. So, SARMs were designed as a safer alternative, offering similar benefits without the harsh downsides.

Now, while SARMs are promising, we still don’t have a 100% green light on their safety. Clinical trials are ongoing, and the FIA hasn’t given its stamp of approval for SARMs to be used by everyone just yet.

But here’s the good news: some SARMs are safer than others. If you’re wondering what is the safest SARM, look no further than MK-677 (technically not a SARM but still popular), Ostarine (MK-2866), Stenabolic, Andarine (S4), and LGD-4033. These are considered the safest SARMs to use.

When it comes to bulking or cutting, you want to use SARMs with least side effects. Whether you’re aiming for muscle growth or fat loss, there are options that can help you reach your goals with minimal risks.

For those looking to build muscle, the safest SARMs for bulking include LGD-4033 and Ostarine. They help you pack on lean muscle with fewer risks. On the other hand, the best SARMs for cutting like Stenabolic and Andarine are great for shedding fat while maintaining muscle.

It’s all about finding the right balance. Whether you’re asking what is the safest SARM to take or looking for the least harmful SARMs, there are options out there that fit the bill. The key is to choose wisely, focusing on the safest SARM cycle that aligns with your goals, so you can get the best results without compromising your health.

1) Safest SARMs: MK 677

MK-677 often gets lumped in with SARMs, but here’s the truth—it’s not a SARM at all. While regular SARMs bind to androgen receptors in muscle and bone tissue to boost muscle protein synthesis, MK-677 works differently.

Instead of binding to those receptors, MK-677 is a growth hormone secretagogue. This means it stimulates your pituitary gland to release more human growth hormone (HGH). The result? You get the benefits of increased HGH, like enhanced fat loss (2), muscle gain, and even improved overall quality of life.

The best part? Because MK-677 doesn’t mess with your endocrine system, it’s known as the “SARM with least side effects.” This makes it one of the safest SARMs to take.

If you’re looking for SARMs without side effects, MK-677 is a solid choice. It’s often considered the safest SARMs to use when your goal is muscle growth or cutting fat. Whether you’re after the best SARMs for bulking or the safest SARMs for muscle growth, MK-677 offers a reliable option with minimal risks.

In the world of safe SARMs, MK-677 stands out, not just for its effectiveness but also for its safety profile. So, if you’re asking what are the safest SARMs or searching for the safest SARMs for cutting, MK-677 should be on your radar. It’s an excellent addition to any safest SARM stack.

2) Mildest SARM (Most Researched): Ostarine MK-2866

Ostarine (MK-2866) is a popular choice among those seeking the safest SARMs. It’s known for its mild nature, making it a top pick for both beginners and experienced users. If you’re asking what SARM has the least side effects, Ostarine often tops the list. 

You won’t have to worry about the usual issues like bloating or other uncomfortable side effects.

This SARM has plenty of research backing it, making it a reliable option for those who want to build muscle and burn fat at the same time. It’s often considered the best SARM for muscle growth due to its ability to deliver steady gains without the harsh side effects that other options might bring.

If your goal is to bulk up safely, Ostarine stands out as the safest SARM for bulking. It supports muscle growth while keeping the risks low, which is why it’s so well-loved in the fitness community.

But that’s not all. Ostarine is also a strong contender for the best SARM for cutting. It helps you maintain your hard-earned muscle while shedding unwanted fat, making it a versatile option for various fitness goals.

Overall, Ostarine MK-2866 is a smart choice if you’re looking for a SARM that balances effectiveness with safety. Whether you’re bulking, cutting, or just looking for a SARM with the least side effects, Ostarine has got you covered.

3) Safest SARMs for Fat Loss: Stenabolic SR9009

Stenabolic SR9009 is another one of the “safest SARMs” that is in reality, not a SARM. Stenabolic is known as a REV-ERB and will increase the Rev-ErbA affinity in our body.

Stenabolic is not one of the more popular SARMs, and the reason for this is that it isn’t actually hormonal at all – it does not cause Testosterone downregulation at all. This also means that there is no PCT needed and no Testosterone replacement therapy risk.

Why would you even want more Rev-ErbA? Well, it can increase lipolysis, decrease adipogenesis, and improve inflammatory responses from the body [6].

So not only will Stenabolic increase the amount of fat you lose, and fight muscle wasting, but some even say it can improve sleep.

4) Safest SARMs for Strength: Andarine S4

Unlike some of the other safest SARMs on this list, Andarine S4 is a simple and straightforward SARM. It will bind to the Androgen Receptors throughout the body and cause biological changes.

Andarine is known to be quite good at helping individuals cut weight. Unlike Anabolic Steroids, there is very little chance that this compound will cause Estrogenic side effects.

Andarine will give you a very dry look while also helping you with building lean body mass as well as increasing bone density. It was originally developed for patients suffering from muscle wasting and bone problems (as they age).

While Andarine is relatively safe, there are definitely effects on the eyes as users have reported “yellowing” of vision. They also claim that it can make the eyes very sensitive to light.

5) Safest SARMs for Muscle Growth: Ligandrol LGD-4033

Ligandrol LGD-4033 is a selective androgenic receptor modulator (SARM) that was developed by Ligand Pharmaceuticals. It is primarily a mass-building SARM that was originally developed to treat muscle-wasting conditions.

Ligandrol is one of the best SARMs for increasing lean mass and it activates the muscle regeneration process after a workout. This SARM also increases both energy and strength.

Ligandrol can be stacked with a cutting SARM for weight loss to preserve muscle size while you are stripping off body fat.

In terms of weight loss, Ligandrol is able to attach to fat receptors and stimulate fat loss. It will boost the metabolism for faster calorie burning.

How Do Selective Androgen Receptor Modulators (SARMS) Work?

The human body has Androgen Receptors throughout that are meant to be bound by ligands. In particular, these ligands include human hormones such as Testosterone. This is completely normal and healthy, and can even be exploited.

By massively increasing the number of certain ligands in the body, we can see massive biological changes, particularly in metabolism, body fat levels, bone density, and muscle mass.

We know from a study published in the New England Journal of Medicine that Testosterone alone will build muscle mass [9] – no exercise is needed! Just look at the graph!

SARMs will do something similar to Steroids, just not quite as powerful. SARMs will bind to the Androgen Receptors in the body, causing muscle growth. Easy right? Let’s make it a bit harder. This is how SARMs work:

Step 1: Steroid Hormone or SARM binds to the Steroid Hormone Receptors

Step 2: Hormone/SARM-Receptor complex enters the Nucleus

Step 3: The complex will bind to the receptor sites on the chromatin

Step 4: This activates mRNA transcription

Step 5: mRNA leaves the nucleus

Step 6: Ribosomes translate mRNA into new proteins

This is the process in which SARMs will help you gain muscle. These compounds will also not bind to all the receptors in the human body, unlike Anabolic Steroids, which will bind to everything.

Safest SARMs for Bulking

Bulking is a term usually used by individuals looking to gain quite a bit of muscle mass and don’t mind gaining a bit of pudge as well. Not the “leanest” option available.

The safest SARMs for bulking would have to be Ligandrol LGD 4033 because it’s actually got some potency. Yes, there are side effects, however, if your goal is bulking, you’re looking for something with significant benefits.

This means taking a few L’s and choosing the appropriate Selective Androgen Receptor Modulator. It might be a wise idea to keep some PCT or anti-aromatase products on hand.

Safest SARMs for Lean Muscle Mass

Conversely to “bulking”, trying to gain lean muscle mass usually means a more careful approach. Someone looking to improve muscle mass, someone looking to use some body-building products to cause muscle growth without any fat gain or bloat.

The safest SARMs for lean muscle mass would have to be Ostarine. Ostarine is known to be somewhat mild in its physical function, and that means that you simply won’t be experiencing the heavy sides.

You can still experience a significant amount of muscle growth, and you certainly will do less damage than any Anabolic Steroid.

Safest SARMs for Fat Loss

Fat loss differs ever so slightly from “cutting” because, in my opinion, fat loss can apply to anyone and everyone. Only athletes (specifically physique athletes) will cut.

The safest SARMs for Fat Loss would have to be MK-677 (again, not really a SARM). MK 677 is known as a Growth Hormone secretagogue that will increase the amount of Growth Hormone the pituitary produces.

Growth Hormone has few if any “real” side effects when used in normal doses. It can definitely lead to insulin resistance if you totally abuse the product in question, however, you have to be eating like an absolute pig (and using way too much for that to happen).

MK 677 will lead to increased levels of Lipase in the body, which in turn will greatly increase lipolysis – fat loss. It is pretty average at inducing muscle growth, however.

Safest SARMs for Cutting

Cutting is reserved for athletes mostly. Physical function plays a massive role in their progress, as they need to battle muscle wasting as much as they possibly can. Other SARMs like MK 677 would help, sure, but I think the safest SARMs for cutting is Ligandrol.

It is going to do a better job at stopping muscle wasting when dieting than some other SARMs on this list, and in clinical trials, it has been shown to aid slightly in the act of losing fat.

If you diet correctly, you even stand a chance of increasing lean muscle mass! But, you have to be doing everything perfectly for that to happen.

Safest SARMs for Beginners

Beginners are often misinformed that they can take substances without any sides. There are always going to be some side effects, these are not dietary supplements after all. This is why the World Anti-Doping Agency bans these compounds.

That said, if you are 100% sure about using one of the safest SARMs, you could look at Ostarine. Typically, it is not going to have a lot of side effects, and it is the SARM with the most amount of clinical trials supporting it.

Dosage of Safest SARMS:

SARM	Dosage	Key Benefit
MK-677	20-25mg per day	Muscle growth 💪🔥
Ostarine MK-2866	10-25mg per day	Muscle preservation 🛡️💪
Stenabolic SR9009	20-30mg per day	Stable levels ⏰🔄
Andarine S4	20-25mg per day	Avoid vision side effects 👁️🌀
Ligandrol LGD-4033	5-10mg per day	Muscle gains 🏋️‍♂️👌

MK-677 is often dosed at 20-25mg per day. This dosage helps with muscle growth and fat loss while minimizing side effects.

Ostarine (MK-2866) is considered safe with a dosage of 10-25mg per day. It supports muscle preservation and is gentle on the body.

Stenabolic SR9009 is effective at a dosage of 20-30mg per day. It is taken in multiple doses throughout the day to maintain stable levels.

Andarine S4 typically has a dosage of 25-50mg per day. Users often cycle it for 6-8 weeks to avoid vision side effects.

Ligandrol LGD-4033 is safe at 5-10mg per day. This low dosage supports muscle gains with minimal risks.

Benefits of SARMs

SARMs are a term used to describe a massive amount of compounds that all have different chemical structures, and they will have different effects based on that structure. That said, SARMs can have the following benefits:

• Increase in lean muscle tissue
• Decrease in body fat levels
• Improving your cardiovascular and muscular endurance
• Greater bone density
• Better sleep
• Certain SARMs can even increase libido and sexual function

While SARMs do have a host of benefits, it’s important to remember that SARMs can still have side effects. No official regulatory body has approved SARMs for human use, and that will only happen when all the side effects have been fully studied, etc.

Which SARMS are the Harshest?

YK-11 is one of the harshest options available. It is a myostatin inhibitor rather than a typical SARM. Users have reported side effects similar to those of anabolic steroids. These include testosterone suppression, raised liver enzymes, increased cholesterol, acne, and joint pain.

S23 is another potent SARM known for its significant impact on muscle strength and pumps. However, it also comes with harsh side effects, the most severe being extreme testosterone suppression. This makes it a less favorable choice for many users.

RAD 150 is a newer and more potent variant of RAD 140. It is known for being harsher due to its stronger effects. RAD 150 users often experience more pronounced side effects compared to those using RAD 140, which, along with LGD 4033, is considered moderate in terms of side effects.

SARMs vs Anabolic Steroids

The first thing you need to know is that SARMs and Steroids do exactly the same thing, just in different manners.

Both SARMs and Steroids will bind to the Androgen Receptor Cells, and cause a biological change from there. The process is explained in a paragraph higher in this article, however, it is important to remember that these substances do the same thing.

The only difference is that Steroids have the potential to be way more impactful on your body. Steroid users have a greater risk of developing prostate cancer, worse cholesterol readings, and Testosterone suppression. This is because Steroids are a lot stronger than SARMs.

SARMs do, however, need a lot more research done on them before we have a grasp as to how these compounds act on a long-term scale.

Safest Place to Buy SARMs

Finding a reputable SARM supplier online is pretty hard and for good reason. These guys can label their products as anything and since the dietary supplement industry doesn’t regulate these compounds, they aren’t tested.

That said, we have made use of Amino Asylum for a long while now, and they have never disappointed us. They have everything from RAD 140 to even other products, like a Selective Estrogen Receptor Modulator.

They have a large number of great reviews on their site and on Reddit, and if you spend some time online, you’ll soon realize that Amino Asylum is the leading SARM supplier in the States.

Safest Way to Take SARMs

SARMs are experimental, they are literally sold as research chemicals! So, if you are terrified of any side effects at all, be careful of which SARM you choose to use.

Here are some tips on how to use SARMs safely:

• Don’t use too much, follow the recommended dosing
• Don’t use the strongest SARMs, start off with lighter ones and move up
• Do not run cycles that are longer than recommended
• Have your bloodwork done to see how your hormones change, like with LetsGetChecked
• Use other substances like a Selective Estrogen Receptor Modulator (SERM) and aromatase inhibitors as needed
• Make use of a PCT once you have completed your cycle

Are SARMs Legal?

The use of a Selective Androgen Receptor Modulator or SARM is technically illegal. These are classified as “not for human use” and they may not be sold as dietary supplements.

That said, SARMs are legal to purchase under the term “research chemicals”, as are some other compounds like Peptides. SARMs are however banned by the World Anti-Doping Agency in professional sports.
