Best SARMs for Beginners: A Safer Starting Guide (2025)

If you’re new to SARMs and want to build lean muscle or support fat loss without jumping straight into steroids, this guide is for you. Some SARMs are mild and beginner-friendly, while others are far more suppressive and risky.

Here, we break down the best SARMs for beginners based on safety, results, and side-effect risk, so you know exactly where to start-and what to avoid.

Originally developed for medical research, SARMs are now widely sold online as research chemicals, making smart choices more important than ever.

Let’s get into the beginner-friendly options.

Key Takeaways

• Not all SARMs are beginner-safe—starting with mild, low-suppression options matters most 🛡️
• MK-677 and Ostarine remain the most popular entry-level choices for first-time users ✅
• Stronger SARMs can suppress natural testosterone and may require proper PCT ⚠️
• Results depend heavily on diet, training, sleep, and dosage discipline 📊
• SARMs are still research chemicals—long-term safety data is limited 🧪

Beginner-Friendly SARMs: How to Choose the Right Starting Options

Not all SARMs work the same way. Some boost growth hormone, others bind directly to androgen receptors to support muscle growth, and a few simply don’t live up to the hype.

For beginners, the goal isn’t chasing the strongest compound—it’s choosing options that balance results, safety, affordability, and long-term impact. That’s exactly what this list focuses on.

Below, we break down the most beginner-appropriate SARMs based on real-world use, side-effect profile, and overall effectiveness.

#1 Best SARM for Growth Hormone: MK 677

MK 677 is commonly grouped with SARMs when in reality it is not a SARM at all. Regular SARMs will bind to the Androgen Receptors in the muscle tissue (and bone tissue as well) to cause an increase in muscle protein synthesis.

MK 677, however, is a Growth Hormone secretagogue, meaning it will not interact with the Androgen Receptors at all, but only cause an increased release of Human Growth Hormone (HGH) from your own Pituitary gland.

Increased HGH can lead to increased fat loss [1], and muscle gain, and even improve overall life quality.

Because MK 677 does not interact with the endocrine system at all, it is the “SARM” with the least amount of side effects, making MK 677 a very safe SARM and great for beginners.

MK-677 – Swisschems

MK-677

MK-677, also known as Ibutamoren, is a potent growth hormone secretagogue that stimulates natural GH and IGF-1 production by activating the ghrelin receptor (GHS-R1a). Unlike traditional peptide injections, MK-677 is taken orally, offering an effective and convenient way to support growth hormone levels.

This compound is widely researched for its potential to enhance recovery, increase muscle fullness, improve sleep quality, and promote lean mass retention. It works by mimicking ghrelin, a hormone that signals the body to release more growth hormone, while also influencing appetite and energy balance.

Many athletes and researchers note improved sleep patterns, faster tissue repair, and steady body composition benefits during controlled studies. MK-677 does not suppress natural testosterone production, making it an appealing compound for research on long-term GH regulation.

#2 Least Side Effects: Ostarine MK 2866

Ostarine MK 2866 is one of the SARMs people love for its mildness. Not only will this SARM not really cause you any side effects, but you will also see gradual gains rather than bloating.

Ostarine MK 2866 is the SARM with the most research behind the name, and the one most people start off with. Studies have found that this SARM can actually help you burn some unwanted fat while building muscle, without causing real side effects [2].

For those that have serious safety concerns, Ostarine can cause some heartburn and nausea when you abuse the compound way above recommended doses.

This is the Selective Androgen Receptor Modulator that most people reach for in the beginning to stimulate anabolism, and can aid your intense weight training in more than one way.

Ostarine – Science.bio

Ostarine

Ostarine, also known as MK-2866, Enobosarm, or GTx-024, is a selective androgen receptor modulator (SARM) originally developed to help treat muscle wasting and osteoporosis. Unlike anabolic steroids, it was designed to bind selectively to muscle and bone tissue, aiming to minimize unwanted effects on other organs.

In research settings, Ostarine is investigated for its potential to promote lean muscle mass retention, enhance strength, and support recovery. Fitness enthusiasts and biohackers often highlight it as one of the most popular SARMs due to its relatively mild profile compared to stronger compounds.

Science.bio offers Ostarine in a liquid solution (30mg/mL, 900mg total) with batch-coded lab reports and third-party analysis available for transparency. Each bottle includes a UV-resistant glass container, tamper-proof seal, and graduated pipette for accurate measurement.

#3 Best SARM for Recovery: Stenabolic SR9009

Stenabolic is another “SARM” 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 [3].
So not only will Stenabolic increase the amount of fat you lose, and fight muscle wasting, and some even say it can improve sleep as well.

SR9009 – NextChems

SR9009

SR9009 (Next Chems) is a research compound best known for its role in metabolic regulation, endurance output, and fat oxidation through activation of the REV-ERBα pathway.

#4 Safest SARM for Muscle Growth: Andarine S4

Unlike some of the other 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.

S4 (Andarine) – SwissChems

S4 (Andarine)

S4 (Andarine) is a non-steroidal Selective Androgen Receptor Modulator (SARM) originally developed for research into muscle wasting, osteoporosis, and androgen-deficiency conditions. It works by selectively binding to androgen receptors in skeletal muscle and bone tissue, while minimizing interaction with androgen-sensitive organs.

In laboratory models, Andarine has been studied for its role in lean muscle preservation, fat loss enhancement, recomposition efficiency, and strength output during caloric restriction phases. Its partial agonist behavior makes it a popular research compound for cutting-focused protocols.

Swiss Chems supplies S4 (Andarine) at 25mg per capsule, 60 capsules per bottle, produced under strict quality control standards with ≥98% purity verification. Each batch is sealed in tamper-proof bottles intended strictly for research use only.

#5 (The Big Boy) Strongest SARM for Beginners: Ligandrol 4033

Ligandrol LGD 4033 is another of the most popular SARMs, especially for beginners. LGD 4033 is also often used by women because it has so few side effects. That said, it might have more sides than any other SARMs on the list.

That said, it is quite a lot stronger than Ostarine. This means you will be facing some side effects, and you can expect some Testosterone suppression.

This is really just a stronger “entry-level” SARM, meaning it was theorized to treat muscle wasting in severe cases. It can increase lean muscle tissue while also helping you lose body fat.

Some users have claimed benefits further than just muscle building, such as improved recovery from training sessions.

LGD-4033 (Ligandrol) – Science.Bio

LGD-4033 (Ligandrol)

LGD-4033 (Ligandrol) is a highly researched Selective Androgen Receptor Modulator (SARM) originally developed for conditions involving muscle wasting and bone degeneration. It selectively targets androgen receptors in muscle and bone tissue, allowing strong anabolic signaling with significantly reduced androgenic activity compared to traditional anabolic steroids.

In controlled research environments, LGD-4033 has demonstrated powerful effects on lean mass accretion, strength output, nitrogen retention, and recovery efficiency, making it one of the most widely studied SARMs for recomposition and bulking models.

What are SARMs?

In the early 1900s, doctors began experimenting with Anabolic Steroids as a treatment for individuals who were losing muscle mass due to an illness like HIV/AIDS. Unlike SARMs, Steroids would bind to all the Androgen receptors and cause severe side effects.

How Anabolic Steroids were used in the medical world meant that people who were sensitive to androgenic side effects (women and children) would suffer the most. Sure, you get muscle development but at the expense of losing your hair and increasing cholesterol dramatically.

Clinical trials showed that Testosterone and other Steroids do work, they increase muscle mass, increase bone density, and improve physical function. However, they just could not deal with the adverse effects.

SARMs were designed to replace Steroids in the medical world. They would be increasing lean body mass without causing as many adverse effects. SARMs bind to Androgen Receptors just like Steroids do, but only to those found in muscle and bone tissue. They do not require post-cycle therapy, unlike Steroids.

Do SARMs really Work?

SARMs have been tested for a few years and some studies have shown their effectiveness in clinical trials. However, they are not as powerful as Anabolic Steroids. That said, they do still work.

A 2013 study found the SARM mentioned above LGD 4033 to be effective in building lean muscle mass [4].

While there are multiple SARMs available online today, only a few have been tested for the doses used as performance-enhancing supplements would be. They might not be able to give you the massive muscle gains that Steroids would, but they certainly are effective.

Best SARMs for Lean Muscle Mass

With so many SARMs claiming rapid muscle growth and SARMs sellers claiming each SARM is good at increasing muscle mass – which is actually going to be best?

Well, as beforementioned, for beginners your best bet is going to be Andarine S4 or Ligandrol 4033. There might be an argument here for RAD 140, however, I prefer the other two. Some of these will cause downregulation of natural Testosterone production, and you should take this into account when you buy SARMs online.

A few cycles might not hurt you, but SARMs work on the HPTA and can cause problems down the line, especially if you use the wrong SARMs stacks.

Best SARMs for Fat Loss

While most SARMs and Steroids are used to encourage lean muscle growth, certain SARMs can lead to better fat loss as well – well, they’re not actually SARMs.

MK 677 is known as a Growth Hormone secretagogue, and HGH itself will lead to higher levels of Lipase – which in turn will lead to better lipolysis (fat loss).

Another option is Cardarine, which is going to help with lipid metabolization. Both can be used together, in fact stacking SARMs is commonplace in bodybuilding – granted the side effects can become hard to manage.

While these can help in your endeavor to burn fat, the best course of action is still the good ‘ol calorie deficit and cardio.

Do SARMs require Post Cycle Therapy (PCT)?

A PCT is what is used after a cycle of Steroids or SARMs to fix your Testosterone levels. The influx of exogenous hormones of a Testosterone nature can cause a downregulation of your natural Testosterone production.

This will happen with all Anabolic Steroids, but only with some SARMs. This is also dose and time of dose dependant. Most people will just get the athletic performance benefits, pop a few Nolvadex and pin a bit of HCG and be completely fine.

You can purchase HCG from Swiss Chems: (BUY NOW)

Most SARMs do require a PCT of sorts, maybe a Selective Estrogen Receptor Modulator or HCG will do the trick. Again, the harder you push, the harder it will be to reactivate Testosterone levels.

Are SARMs Safe?

For the most part, sure. There simply are not enough studies or anecdotal evidence to know all the side effects these compounds have.

And you might reply with “Well, Steroid users still survive?!” and you would be correct – they do. However, Steroids have been studied extensively and have been abused by millions of men and women. We know what happens when you use more than 500mg of Trenbolone per week, spoiler alert, it ain’t good.

Side effects of SARMs, whether you use them for lean mass or for burning fat, we simply do not know all of the relative sides yet. Therefore, there is still some danger to using these compounds.

SARMs vs Steroids

SARMs are often compared to Steroids and for good reason. They both act upon the same site, the Androgen receptor. Both can be used for muscle gain or to improve athletic performance. Both can even lead to increased bone density! That said, they differ wildly from one another.

SARMs will not bind to all the receptors in the body as Anabolic Steroids would. The prime example of this would be the fact that SARMs do not have an affinity for the prostate. They do not cause as much hair loss. They don’t really cause virilization in females (some do).

So, SARMs are just less powerful in regard to sides. But, they are also a lot weaker. The downside of having fewer side effects is the fact that they are not as strong.

Beginner SARM Cycles

Using a SARMs stack is super common, and you can build a muscle mass or cutting cycle(s) by combining the correct SARMs with one another. Just be weary that combining more than one new compound is not advised at the same time. If you have adverse effects, how do you know which one was causing it?

Beginner SARM Cycle for Muscle Mass

Once you have your training, diet, and recovery in check, you can start looking at using SARMs to improve your results. The best beginner SARM cycle for muscle mass would be:

• MK 677 (before bed)
• Andarine S4
• (maybe) Ligandrol 4033

Beginner SARM Cycle for Fat Loss

Once you have your training, diet, and recovery in check, you can start looking at using SARMs to improve your results. The best beginner SARM cycle for cutting would be:

• MK 677 (before fasted cardio)
• Cardarine GW 501516
• (maybe) Ligandrol 4033

Are SARMs Legal?

SARMs can be purchased under the nomenclature of “for research purposes” or “research chemicals” but may not be sold for human consumption. More tests are needed, and they have not been approved by the FDA for human use yet.

Best place to find SARMs online?

You have two options, either going through an HRT clinic (you would be limited to certain SARMs, mostly for muscle recovery) such as Evolve HRT.

The second option would be using an online vendor like Sports Technology Labs or Amino Asylum. These are two of the most tested and trusted vendors on the market currently.

SARMs to Avoid

As a beginner, certain SARMs should be avoided like the plague because they can be severely detrimental to your health. These include YK-11 and S23, as they are incredibly powerful, and will have equally intense side effects.

Conclusion: SARMs for Beginners

SARMs can offer a middle ground between natural training and full anabolic cycles – but they’re not a shortcut or a toy. Beginners who choose to experiment should already have solid training experience, consistent nutrition, and realistic expectations in place before starting.

Less is always more at the beginning. Mild compounds, conservative dosing, and proper recovery will take you much further than rushing into stronger options. Progress should be built gradually, not forced.

Most importantly, SARMs are still research compounds, not fully approved performance supplements. That means long-term safety data is limited, and responsible use is essential. Train smart, stay patient, and always put your health first.
