What are Selective androgen receptor modulators?

SARMs or selective androgen receptor modulators are a relatively new class of performance-enhancing substances.

They work by mimicking the effects of androgens like testosterone and Dihydrotestosterone.

This means that they help to build muscle, increase strength, increasing bone density, prevent bone loss and promote fat loss.

SARMs are currently being researched for a variety of therapeutic applications such as the treatment of breast cancer, muscle wasting & muscle loss caused due to injury or disease.

Most of these conditions, such as breast cancer treatment, muscle wasting diseases, and an increase bone density, were earlier the domain of anabolic compounds.

But the adverse effects are so strong that the applications are limited.

However, SARMs do not produce all the same side-effects as traditional AAS because they’re nonsteroidal hormones that bind only to certain receptors in muscle tissue cells, sparing the organs like the prostate gland.

They are designed to have minimal androgenic effects while exerting anabolic effects.

In a performance enhancement setting, if you are looking to bulk fast, without some of the negative side effects associated with conventional AAS, then here are the best SARMs for you.

#1 – RadBulkBest SARM for lean muscle mass

RadBulk is the legal version of Testolone RAD 140. Anyone who has ever heard of SARMs must definitely have heard of Rad.

It is one of the most popular selective androgen receptor modulators on the market today, currently in Phase 1 of clinical trials for muscle wasting treatment.

Rad is a selective androgen receptor modulator that has been used extensively by athletes because of its innate ability to promote muscle repair while burning fat at the same time.

Its popularity also stems from its versatility. This is one of the best SARMs that you can use for both bulking cycles as well as for cutting cycles.

When you use it with a calorie surplus diet, it will increase muscle. But it has a mild fat-burning effect too. So, if you switch over to a cutting cycle, it will help preserve your muscle tissue.

While we are discussing SARMs for bulking, Radbulk is a terrific option for fat loss and maintenance too.

Why RadBulk is the best SARM for quick muscle growth?

Radbulk ticks both the boxes that you look for, in a SARM for gaining muscle fast. It creates the perfect anabolic environment, allowing your muscles the tools they need to repair, renew and rebuild at an accelerated rate.

To top it off, it primes your hormone levels, by bumping up T levels, making it one of the best SARMs for fast gains.

  • Bumps up Muscle Protein Synthesis

Radbulk has such a strong effect on your Free T levels that it helps in building muscle by enhancing the cell signaling pathway known as mTOR.

This plays a major role in protein synthesis while reducing muscle catabolism thus improving muscle while promoting fat loss.

If you are in a calorie surplus? Expect amazing gains in no time.

  • Enhances endurance

Radbulk also helps in increasing the time you can exercise, by enhancing your stamina levels thus improving endurance levels.

It aids in protein synthesis and improves Nitrogen balance, which makes sure that the protein you take is used efficiently for muscle rather than being wasted out of the body through urine.

Increased nitrogen retention in muscles provides them with an adequate amount of amino acids for optimal health and growth of muscle, apart from promoting fat loss.

What are the ingredients in Radbulk?

Radbulk is a blend of 5 natural ingredients that, when used together, synergistically provide the perfect hormonal support needed for quickly gaining lean muscle tissue.

Acetyl L-Carnitine HCL –Acetyl L-Carnitine HCL contributes to the production of cellular energy by transporting fatty acids into the mitochondria. In Radbulk, it helps with cutting stubborn fat and increasing muscle.

But very few people know that ALCAR is a growth hormone secretagogue. It stimulates the endogenous production of GH, which is a very underrated hormone to boost energy, build muscle, and fat cutting. Alcar does it without causing uncontrolled bone growth and other side effects associated with it.

Choline Bitartrate – Choline Bitartrate provides dietary support for healthy homocysteine levels. It also supports neurotransmitter communications and specifically, acetylcholine synthesis, which is essential for razor sharp focus and brain function when you lift.

In Radbulk, Choline Bitartrate has been included to provide a focused energy boost without the jittery side effects of other stimulants.

Wild Yam – Wild Yam has been clinically proven to increase testosterone naturally by inhibiting the enzyme aromatase, which converts testosterone into estrogen.

Wild Yam also prevents cortisol from binding to its receptors in muscle tissues, thereby helping prevent the breakdown of lean mass, that can occur during stressful activity such as intense weight lifting.

In Radbulk, Wild Yam has been included for pre-workout support that helps to increase testosterone and minimize cortisol, which can both lead to increased lean muscle tissue gains.

Dimethylaminoethanol – Dimethylaminoethanol is a chemical compound that affects the neurotransmitter acetylcholine in the brain, to increase alertness and mental energy.

In addition, it can help with memory recall and learning processes. In Radbulk, Dimethylaminoethanol has been included for its ability to provide a sharp boost of energy that can last throughout a workout.

Safflower Oil – Safflower Oil is an excellent source of the essential fatty acid linoleic acid and provides all omega 6 fatty acids.

In Radbulk, Safflower Oil contributes to increased testosterone production and can help with muscle gains without adding excess body fat.

Why we highly recommend Radbulk?

Radbulk is one of the best SARMs for quick bulks as well as slow sustained weight gain. It is better suited for the former though because of its rapid absorption and dramatic results.

Here’s why Radbulk is one of our favorite SARMs for bulking.

1- Promotes muscle mass in multiple ways

  • Boosts testosterone, increases protein synthesis and nitrogen retention.
  • Dry muscle gains with a visible reduction in stubborn fat mass
  • Vascularity is an added benefit. Almost like using Testosterone and Anavar, which are a potent combo of anabolic compounds.

2- No Side effects like Selective androgen receptor modulators

Does not affect your androgen receptors and hence will not produce adverse effects like testosterone suppression which is common in testolone rad 140. No need to use a PCT supplement.

3- One of the best SARMs for rapid results

  • One of the best SARMs that will build lean body mass and burn body fat at the same time.
  • Kicks in within days and produces an intense boost in strength, vascularity, and pumps
  • Versatile enough to be used for both cutting and bulking cycles. Hence, Radbulk is also one of the best SARMs for cutting.
  • Comes with a 100-day money-back guarantee

#2 – LigabulkQuick Muscle Booster

If your fitness goal is muscle growing without messing around with losing fat, then Ligabulk is the best SARM for you.

As implied by the name, this is the legal alternative to Ligandrol or LGD-4033, the most popular bulking selective androgen receptor modulator, for quickly gaining body weight.

Ligabulk mimics the results of LGD 4033 by increasing glycogen storage, shifting the energy balance, improving nitrogen ratio, and of course, protein synthesis.

It is like using Dianabol, one of the strongest Anabolic steroids. Only, Ligabulk does not produce any of the native effects that anabolic steroids do.

Why Ligabulk is the best SARM for muscle?

Ligabulk focuses solely on hypertrophy. This is one of the best SARMs that boasts of this unique ability. It is extremely selective in exerting its actions, which means that its perfectly suited for razor-targeted fitness programs.

  • Amplifies Glycogen Storage and hence boosts muscle growing

Ligabulk works by amplifying a muscle cell’s ability to uptake glycogen and helps in protein synthesis, which results in rapid muscle growth at a much faster rate than when you lift weights.

Glycogen increases the speed of muscle recovery after you lift heavy weights. Clubbed with the right nutrition, this will lead to rapid cell growth and hence result in hypertrophy.

  • Stimulates Growth Hormone, Testosterone & IGF-1

Ligabulk creates the perfect anabolic setting by stimulating the release of natural growth hormone, testosterone, and IGF-1.

This troika is so powerful that it can amplify muscle strength and power output – even without training – leading to increased muscular gains even if you lollygag in front of the mirror.

That’s why even recreational lifters undergo complete body composition transformations with Ligabulk.

What are the ingredients in Ligabulk?

Ligabulk is a blend of 7 natural ingredients, which are tasked with just one goal. To increase the rate of muscle gain to anabolic steroids levels.

Naturally, the list is carefully selected. There are some potent hormone boosters, amino acids that help in enhancing muscle recovery, and energy boosters that will help you make the most of your workouts.

Vitamin D3 – Vitamin D3 helps boost testosterone levels, reduce cortisol levels and increase insulin-like growth factor 1 levels which makes it possible to gain muscle fast after a workout. Vitamin D3 also helps the body absorb calcium.

Methyl Sulfonil Methane -MSM helps boost growth hormone levels, increase collagen production, and helps the body use calcium.  MSM also aids in joint health allowing you to train harder and longer improving your overall performance.

Suma Root – Suma root is clinically proven to increase growth hormone levels by over 450%. It also helps promote better sleep, aiding recovery, increases muscle strength, and will help you lose body fat fast and gain lean muscle.

Ashwagandha Root -Ashwagandha root’s muscle building and testosterone boosting properties help you build lean muscle while burning fat. It also helps improve athletic performance by building strength and endurance allowing you to train harder for longer. It is also a potent adaptogen that will keep you energized and focused.

Tribulus Terrestris -Tribulus terrestris helps boost strength, increase lean muscle mass, and increases bone strength making it one of the best natural testosterone boosters. Tribulus also prevents cortisol production caused by stress allowing your body to recover faster post-workout.

L-Leucine -L-Leucine stimulates protein synthesis helping your body recover and build lean muscle fast. It is also one of the most anabolic amino acids and will keep you in a state of positive nitrogen balance allowing more protein to be synthesized. This means more mass gains!

Sodium Hyaluronate

Sodium hyaluronate reduces post-workout muscle damage by creating a protective barrier around your muscles. This allows you to train harder for longer sessions increasing lean muscles mass and strength gains.

Why we highly recommend Ligabulk for rapid muscle growth?

Ligabulk is one of the best SARMs for boosting lean mass. There are many other SARMs that are effective at muscle building mind you.

But Ligabulk is the best of them all. It is the no-nonsense, fast mass gainer that most hard gainers seek, after struggling for years to build a good physique.

1- Rapid Absorbing Formula for quick muscle growing

  • Fast Absorbing formula that boosts muscle gain by increasing Glycogen storage in muscle tissue. This creates the perfect setting for anabolism and hypertrophy
  • Preferred by bodybuilders to build muscle mass and muscular endurance over testosterone replacement therapy. No need to use a PCT supplement either after the cycle to keep your gains since it does not bind to androgen receptors.

2- Amazing Pumps

  • Huge pumps and quick bulking SARM
  • Rapid increase in strength which is a perfect adjuvant for fast muscle building
  • Helps you breach plateaus and add tons of weight to your 1 rep max lifts

#3 – YKBulk5 Times stronger than other SARMs

When Rad140 Testolone was launched, most of the athletic community expected that this was the strongest SARM of them all. Then came YK 11 and it set new records for mass gain and strength.

YK11 is a relatively new compound on the market with an affinity to bind to the androgen receptors in muscle tissues that is 10 times higher than testosterone.

It is actually not a selective androgen receptor modulator. Instead, it is a myostatin inhibitor, which inhibits the levels of myostatin in your body, and increases follistatin levels.

Any compound that strong also cause severe side effects. YK 11 can shut you down completely, almost like anabolic steroids. That’s why Brutal Force developed YKBulk, the legal YK11 alternative.

If you seek a legal bulking agent that will encourage lean muscle at 5x the rate of other SARMs, look no further.

Why YKBulk is one of the strongest SARMs?

Bodybuilders or recreational lifters who have used anabolic steroids often complain that they find SARMs underwhelming. YKBulk is the only SARM that’s used by professional bodybuilders for building muscle.

That should give you some perspective of the kind of results you can expect with YKbulk. In fact, for this reason, we generally recommend that YKbulk only be used by experienced users.

The results can be overwhelming for first-timers running their maiden SARMs cycle.

  • YKBulk multiplies muscle stem cells

Muscle stem cells are those from which new myocytes (muscle fibers) form during skeletal muscle regeneration, after injury, or as a result of exercise. YKBulk increases the number of these stem cells by as much as 58%.

This is one of the most profound effects on muscle growing that any SARM can have and it kicks in within days of the initial dose.

  • YKBulk blocks TGF beta signaling

Transforming growth factor β (TGF-β) is a signaling protein that starts the process of making muscle cells into fat cells. YKbulk prevents this from happening.

It also increases IGF-1 levels. The overall impact of these three actions is to greatly increase muscle mass.

Since it also contains anabolic activity at other sites including bone, cartilage, and connective tissue, Ykbulk has very strong overall anabolic activity.

What are the ingredients in Ykbulk?

It’s amazing how Brutal Force has managed to create a mirror replica of one of the most potent SARMs of all time. We expected this supplement to be crammed with hormone boosters and whatnot. But it is actually a blend of just 5-ingredients.

These are handpicked for improving muscle mass and cut fat at an accelerated rate, without negatively affecting hormone receptors in a healthy person who’s lifted naturally all their life.

Tribulus Terrestris –TT is the strongest herbal extract that is able to increase testosterone levels. It also has anti-estrogenic effects due to the protodioscin (PD), dehydroepiandrosterone (DHEA), and flavonoids it contains. As a result, you gain ripped and hard muscle with minimal fat and water retention.

Bulbine Natalensis – This is a herb used in the South Africa body building industry for its anabolic properties. It works by increasing testosterone and IGF-1 levels, and is also quite renowned for its ability to increase stamina and strength in the gym.

Alcar –Alcar or Acetyl L Carnitine is an amino acid which acts as a transporter of fatty acids into the mitochondria (structure within our cells that creates energy). In other words, it works by transporting fatty acids to be used as fuel during your workouts. ALCAR will also decrease fatigue and increase endurance. Also it enhances muscle pumps.

That explains the 24/7 pumped look on YKBulk.

Muira Puama extract – Muria Puama increases the key hormones responsible for anabolism. It is also a natural Myostatin inhibitor which allows for maximum anabolism and minimal catabolism. As a bonus, it is one of the most potent sexual enhancers available, that also has a positive effect on bone density.

Longjack –Eurycoma Longifolia or Longjack has gained popularity amongst recreational lifters ability to increase testosterone levels, improve libido and enhance overall sense of well-being.

It’s one of the most used supplements when it comes to building muscle. Most compounds bind weakly at the androgen receptor (AR), but not Longjack.

Why we highly recommend YKbulk for rapid gains?

Ykbulk is one of the best SARMs for all-around gains. It is primarily a bulking sarm that’s most effective to increasing muscle mass at a rapid pace. But the reduction in Myostatin and the boost in androgen levels also helps in cutting fat.

1- Strongest SARM for rapid bulk

  • Strongest selective androgen receptor modulator for building muscle tissue. Inhibits Myostatin levels in the body. This encourage lean muscle growth like no other SARM.
  • Equally effective at cutting fat, which makes it a unique option.

2- Used by professional bodybuilders

  • Generally not recommended for first timers running their first cycle due to the intense boost in strength and size.
  • Can produce a mild increase in aggression that one generally gets with only androgen receptors binding compounds.
  • Contains no banned ingredients or doping compounds disallowed by the world anti doping agency.

3- No Negative Side Effects

  • Hence no need for a long post cycle therapy to retain your gains
  • Is one of the bestselling dietary supplements in the health and fitness industry.
  • Comes with a 100% money back guarantee.

#4 – IronBound Bulking StackBest SARMs stack for muscle growth

If you have prior experience using SARMs or AAS, or even legal SARMs, then you can straight away jump to the Ironbound Bulking Stack.

By now, you’d be knowing that SARMs are a shortcut to unprecedented gains. This is the best SARMs stack, that is a shortcut for the pros. It is a combination of four of the most potent SARMs for rapidly gaining mass.

If you always wanted to know what you can achieve if you stack SARMs, here’s the answer.

What are the SARMs in the Ironbound bulking stack?

The Iron Bound Stack is a combination of four SARMs in one pack. This makes it the strongest combination of dietary supplements you can use. We have already reviewed three of these SARMs in our list above.

Ligabulk – Quick Mass gaining SARM with dramatic increase in strength. Think of it like using Dianabol.

Radbulk – The lean and dry mass gainer. Think ripped, vascular physique fit for the beach.

YKBulk – The strongest of them all, possibly stronger than even Radbulk.

Ostabulk – Ostabulk is the one SARM that we have not covered. That’s because it has gained a reputation as one of the best SARMs for cutting. That stems from the fact that Ostarine MK 2866, on which it is modelled is a muscle preserving sarm.

But Ostabulk is not Ostarine MK 2866. It is the legal and improvised alternative to Ostarine MK 2866. While it produces a very similar lean physique, it is in many ways better than Ostarine MK 2866.

You can use it to successfully bulk, with lean mass. Also, if you are in a deficit for losing fat, Ostabulk will keep you lean.

Just like the rest of the SARMs, no need for post-cycle therapy with Ostabulk.

Why we highly recommend the Ironbound Stack for lean muscle mass?

The Ironbound Stack was for a long time used only by pro bodybuilders with prior expertise in anabolics. But now, even first timers who are not necessarily a body builder is using it for creating a perfect physique for boasting rights on social media.

  • Gives you a cherry picked combination of SARMs for multiple fitness goals.
  • No need to rely on guesswork to stack SARMs. Just pick the stack and start using them.
  • Contains one selective androgen receptor modulator to meet every fitness goal.
  • Includes some of the best SARMs for cutting, as well as bulking.
  • Comes with Brutal Force’s Iron Clad Money Back Guarantee

Which SARM is best for bulking?

Most users are torn between YKBulk & Radbulk. They also produce different kinds of aesthetics. Radbulk is the ideal choice if you are looking for more vascularity and shredded gains. Ykbulk will be a better pick if you want to gain fast and gain huge.

What is the strongest SARM for muscle growth?

We’d go with YKbulk. The natural Myostatin inhibition is so potent at stimulating muscle that you will breach all your previous records for lifts and size. If you wanted their biceps to rip out of the T-shirt, this is the SARM for it.

What is the strongest SARM on the market?

That’s unfortunately a tough one to answer. The strongest SARM is subjective since people react differently to each SARM. We know of someone who could not tolerate Ostabulk but had great results with YKBulk.

Whereas people generalize that Ostabulk is milder than YK. So, it all depends on your individual body responds to these SARMs.

What’s better LGD or RAD 140?

Again, that’s subjective to what your fitness goals are. If you are looking for a rounded physique with a massive increase in size, then LGD might be a better bet. But if you seek a ripped and shredded finish to the physique, then you will prefer Rad 140.

Final Thoughts

Legal SARMs are a great alternative to AAS and unproven chemicals that can have dangerous side effects. These are manufactured in an FDA-registered facility in the United States. Try these, instead of taking chances with your health.

You will get the same results and gain size in no time.
