The 3 Best SARMs for Bulking

Introduction to the Best SARMs for Bulking

Are you looking to bulk up? Before proceeding, do you know what it means to bulk up? Well, while we may all want to get ripped, it is imperative that you first achieve a considerable frame and put on some muscle mass. Basically, that is what bulking entails; building muscle mass, and you shouldn’t confuse it for gaining bulk.

Anyway, if you are trying to pack on some muscle mass, you probably know that the road ahead is no joke. To make the journey worthwhile and more rewarding, SARMs were introduced to help with weight training by boosting strength, endurance, bulking, cutting and even recomposing your body.

Anyway, this guide will focus on the best SARMs for bulking. By the time you finish reading, you will be in a better position to make an informed choice regarding the SARM you would prefer for your bulking needs.

Ostarine (MK 2866)

Ostarine will always come up when a list of the bests SARMs is being compiled. This SARM, which is highly versatile by the way (effective in both bulking and cutting), was developed by GTx Pharmaceuticals. It was initially developed for treatment in muscle-wasting conditions. Ostarine can also be referred to as Enobosarm or Ostamuscle.

Apart from preventing muscle atrophy, Ostarine can help you to build lean muscle mass, in other words, bulking. However, although Ostarine will help you bulk up with some well-sculpted muscles, it is also instrumental in promoting fat loss. Although this may be regarded as a plus by most, someone who wants to bulk without losing fat may view it as a disadvantage.


Here are some of the benefits that make Ostarine one of the best SARMs for bulking.

  • Foremost, Ostarine has a very high anabolic ratio, which means that its anabolic effects are quite remarkable. As a rule of thumb, the higher the anabolic effect, the more muscle building potential a SARM has.
  • Ostarine slightly elevates the estrogen levels. Hold your horses, don’t fret just yet. Seasoned athletes will tell you that some little estrogen during a bulking cycle could go a long way. Estrogen has a positive effect on bone structure, ligaments (improves range of motion), and tendons. It is for this reason that Ostarine is considered a potential treatment for osteoporosis and people with poor bone density.
  • Ostarine helps to improve muscle recovery, which means that your muscles will heal faster and grow at a much faster rate. Moreover, you will be able to go back to the gym much sooner, without feeling all sore.

Other Ostarine benefits include:

  • Increased protein synthesis
  • Heightened strength,
  • Higher stamina and endurance
  • No post cycle crashes

Dosage and Cycle

The length of an Ostarine bulking cycle is usually entirely dependent on one’s goals. However, the standard Ostarine cycle lasts about 8 to 12 weeks. Going beyond 12 weeks is not advisable as it will increase the risk of testosterone suppression.

You can choose from one of these three options:

  • 10 mg of Ostarine daily for 8 weeks
  • 20 mg of Ostarine daily for 10 weeks
  • 30 mg of Ostarine daily for 12 weeks


You can gain anywhere from five to ten pounds of lean muscle mass when bulking with Ostarine. For better results, you can try taking a lower dose during the first week and slowly increase it as your cycle progresses. Consequently, your androgen receptors will not be laden with an instant high dose of the SARM and will have time to adjust, making them respond better.

If you stick to the recommended dosage, Ostarine barely causes any side effects. However, some individuals have experienced headaches and lethargy. The lethargy may be as a result of testosterone suppression. Not to worry, these sides quickly disappear after completing your cycle.

Ligandrol (LGD 4033)

Ligandrol, aka LGD 4033, is a SARM that was developed by Ligand Pharmaceuticals. It is relatively new to the market, unlike the likes of Ostarine. Despite being new, this SARM has achieved quite a reputation for being one of the best SARMs for bulking, if not the very best. In fact, LGD 4033, is probably the only SARM that can give you results close enough to those of anabolic steroids, without the undesirable impacts.

Moreover, Ligandrol is highly versatile, as it can be used not only for bulking but also for cutting and recomposing your body. However, please do not expect overnight results, as its actions are relatively slow compared to anabolic compounds.


In addition to bulking, Ligandrol has several other benefits. They include;

  • LGD 4033 reduces the recovery time between workout sessions. It ensures that the muscles that were engaged during exercise heal as it also increases their endurance. Besides the physical recovery, this SARM also enhances your psychological recovery. As a result, you can spend long hours training in the gym without your willpower or endurance fading.
  • Ligandrol is a fast-acting SARM and increases protein synthesis, which is essential for bulking.
  • This SARM improves blood flow, which ensures that your muscles receive all the necessary nutrients efficiently, to promote bulking. Moreover, the improved blood flow helps to reduce muscle recovery time.
  • LGD 4033 promotes storage of glycogen in the muscles. The glycogen is later metabolized into energy, which keeps you energized throughout your bulking cycle.

Dosage and Cycle

LGD 4033 is one of the most potent SARMs, which is evident even in the dosage. Check out the recommended dosage and cycle length.

The daily recommended dosage for LGD 4033 is from 3 mg to 15 mg per day. As for the cycle, it is relatively long, stretching from eight to twelve weeks.

You will love to know that after a bulking cycle with Ligandrol, Post Cycle Therapy won’t be necessary. However, given that bodies are never similar if you experience symptoms of low testosterone, PCT is essential. Otherwise, Ligandrol doesn’t cause any other side effects, unless personal ones which cannot be generalized.


Generally, when bulking with Ligandrol, you can expect to gain an average of two pounds of muscle mass every week. However, some of that mass can be lost after completing your cycle as it was merely a result of glycogen storage.

Andarine (S4)

Among all the SARMs in the market, Andarine has the best anabolic to androgenic ratio at 10:1. We’ll get into this later. Anyway, Andarine, also known as S4, is a SARM that’s researched and developed by GTx Pharmaceuticals. Initially, it was being investigated for its potential therapeutic application in preventing muscle catabolism and promoting muscle growth.

Andarine is one of the SARMs with an impressively high oral bioavailability. This means that as soon as it is ingested orally, it begins working to help you achieve your desired fitness goals.

Given its impressive anabolic potential, Andarine produces remarkable bulking gains. What’s more, it doesn’t cause water retention, which means that you will not deflate after your bulking cycle is completed. Essentially, S4 allows you to bulk up and retain both the mass and the strength you’ve gained during the cycle.


Here’s what makes S4 such an excellent SARM for cutting:

  • Promotes gains in muscle mass. Andarine increases protein synthesis and also promotes nitrogen balance in the body. These two provide the foundation for building muscle mass.
  • No water retention. Due to its high anabolic properties, Andarine allows you to safely build muscle without having to be concerned about any unwanted bloating.
  • It provides a stable anabolic environment. For this reason, you can safely use other compounds, knowing that Andarine will not interact negatively or inhibit them from working.
  • Increases strength- In as little as two weeks, you will notice a substantial increase in strength and endurance. In fact, you may even set a new personal best before reaching week 5 of your bulking cycle.


Andarine is required in high dosages, unlike Ligandrol. Ideally, one is advised to stick to 50 to 75 mg of S4 daily. Some anecdotal reports advice taking this SARM for only five days a week. Andarine has a half-life of four to six hours. As a result, you are advised to split the dosage into three to ensure maximum anabolic activity throughout.

While Andarine is potent when used solo, it is particularly effective when stacked with other SARMs. If you want to bulk up, you can stack 50 mg of Andarine with 10 mg of Testolone (RAD 140). However, when taking this combination, you are advised to increase your calorie intake.

The standard Andarine dosage lasts between six and eight weeks, with a two to four-day rest in between bulking cycles.

Side effects

The most common side effect reported by Andarine users is a change in vision. Users have reported experiencing a yellow tinge in everything they observe and having trouble adjusting to night vision. However, the issues cease the moment you stop using Andarine.
