Comparison of the 4 Best SARMs for Bulking

Best SARMs for Bulking

SARMs are selective androgen receptor modulators. They work by selectively targeting muscle cells with stimulating actions that encourage the body to create more testosterone and human growth hormone.

They also increase protein synthesis and speed up fat loss. [1]

Best SARM for Bulking

Testolone RAD 140

Testolone RAD 140 has been on the market for a little over ten years. RAD 140 was developed by a company called Radius Inc. to treat muscle-wasting diseases without the side effects that are inherent with the use of anabolic steroids.

When you take Testolone, it directly stimulates muscle cells and encourages the production of testosterone. It also boosts endurance, stamina, and speed. [2]

Pros

  • Reduces fat and increases muscle mass
  • Improves muscle recovery
  • Increases vascularity

Cons

  • Suppresses testosterone
  • May cause hair loss
  • Liver toxicity
Best SARM for Strength

Myostine YK-11

YK-11, also known as Myostine, has the ability to inhibit the activity of myostatin which is a protein that prevents muscle growth. This makes it an extremely powerful muscle and strength enhancer.

YK-11 has a geometric structure that is very similar to anabolic steroids. Some people actually believe that it is a synthetic steroid that has been mislabeled as a SARM.

It was first studied by a Japanese researcher by the name of Yuichiro Kanno in 2011. [3]

Pros

  • Because of the mechanism in which YK-11 works, it can be beneficial in a cut and a bulk.
  • Can significantly increase strength and muscle growth.
  • Could also increase bone density.

Cons

  • Anecdotal evidence shows hair loss, and acne while using YK-11.
  • Increased aggression.
  • Decreased sex drive.
Best SARM for Beginners

Ostarine MK 2866

Ostarine MK 2866 is generally regarded as the mildest SARM on the market. However, it still has the ability to significantly increase muscle mass while also reducing body fat levels.

That makes it an especially good SARM for beginners to use on their first cycle.

Ostarine selectively works on muscle cells in the body. When attached to the androgen protein, it communicates the message for it to get bigger. Unlike anabolic steroids, Ostarine does not convert to estrogen or DHT. [4]

Pros

  • Ostarine can increase muscle building potential, without minimal testosterone suppressive sides.
  • Ostarine could have potential fat loss effects, combined with a caloric deficit.
  • Ostarine (at a low dose) seems to be safe for females.

Cons

  • Ostarine has been known to have little to no side effects. At higher doses, anecdotal evidence has been found to cause nausea, heartburn, diarrhea and stomach pain.
Best SARM for Women

Ligandrol LGD-4033

Ligandrol is considered by many to be the second most potent bulking SARM after Testolone RAD 140. LGD-4033 is a better option for women than RAD 140 because it is slightly milder.

This compound is nonsteroidal, which means that it will not convert into estrogen. [5]

I suggest that women use half the dosage that men would use on a Ligandrol cycle. Women should start with 5 mg on their first cycle. On their second and subsequent cycles, they should increase the dosage to 10 mg.

Pros

  • Can increase muscle mass
  • Can increase strength
  • Some evidence shows that it can aid in recovery after training
  • Could also help a lot with fat loss

Cons

  • Ligandrol has little side effects, though some anecdotal evidence reports nausea, fatigue, headaches, and low libido.

Bulking

Bulking is a term that bodybuilders use to describe a phase during which they increase their caloric intake while training intensely to increase their lean mass. There may also be some fat gain, depending on how strictly the bodybuilder sticks to their nutritional plan.

SARMs for Bulking

SARMs are generally classified for bulking, fat loss, or recomp, which involves gaining lean muscle mass while losing fat at the same time. All SARMs will provide both lean muscle gain and fat loss results to a certain degree.

Mechanism of Action

SARMs are a type of androgen receptor ligands that bind to androgen receptors and selectively activate androgenic signaling. By their action, they cause testosterone levels to rise, speed up protein synthesis.

SARMs have an antagonistic activity on the prostate and agonistic activity on muscle tissue. As a result, they will increase muscle mass without negatively affecting the prostate.

SARMs Powder

SARMs are available in liquid, powder, and tablet form. They are not available as an injectable.

Buying your SARMs in powder form will be more cost-effective than either of the other forms. However, you will have to put the powder into capsule form before you can make use of it.

That will require purchasing gel capsules, along with a micro-scale and a micro scoop. When you know what your daily dosage will be, make up gel caps that contain that amount and set them aside, ready to get started.

Liquid SARMs

Liquid SARMs are the most popular form of SARMs. That is because they are the easiest to measure out the dosage of.

Most bottles will come with a syringe that makes it easy to do this. However, most people find the taste of the majority of SARMs to be disgusting.

As a result, you should probably chase down your dosage with a glass of juice.

SARMs Cycle

SARMs cycles for bodybuilding usually run between 8 and 12 weeks. I recommend starting with an 8-week cycle.

If you have no complications, feel good and achieve a decent amount of muscle gain, extend it to 10 weeks on your second cycle. On your third and subsequent cycles, you can stretch it out to 12 weeks.

You should follow your bulking cycle with 3 weeks of PCT.

Best SARM Stacks for Bulking

If you want to pack on lean muscle bulk as fast as possible without resorting to anabolic steroids, then stacking with the right SARMs is the way to go. By doing so, you should be able to pack on up to 12 pounds of muscle over a 12-week bulking cycle. To do that, you are going to have to be training 5-6 times er week and maintaining a daily caloric surplus of around 500 calories.

The best SARM stack for bulking pairs RAD 140 and Ostarine.

Take 20 mg of Rad 140 daily along with 25 mg of Ostarine over the course of the 12-week bulking cycle.

SARMs vs Prohormones

SARMs are different from prohormones. Whereas SARMs are selective androgen receptor modulators, prohormones are precursors to anabolic hormones.

They get converted into testosterone and estrogen hormones when they interact with hormones. They then exert androgenic, estrogenic, and progestogenic effects.

In contrast, SARMs only produce androgenic effects, meaning that they have far fewer side effects. Prohormones also have a more pronounced suppressive effect on testosterone than SARMs.

SARMs vs Steroids

Steroids are synthetic forms of testosterone. They affect all organs of the body with the result that, while they undoubtedly increase muscle mass, they also cause problems to such organs as the liver and kidneys.

In contrast, SARMs are able to selectively target muscle and bone cells in order to promote anabolic effects. Rather than a shotgun approach which you get with steroids, SARMs are like a laser targeted sniper shot.

SARMs Side Effects

SARMs may produce mild side effects depending on the constitution of the user. These may include nausea, bloating, headaches, and gas.

The most serious side effect that has been noted with regard to any SARM relates to Andarine S4. People who take more than 50 mg per day of S4 may experience yellowish tinting of their vision, as well as trouble adjusting to light and darkness.

Another effect of SARMs use may be suppression of the body’s natural production of testosterone. This effect, however, is far less than you will get with either steroids or prohormones.

Even so, I recommend doing a course of PCT after every cycle. Women, however, do not need to do a PCT cycle.

SARMs PCT

PCT stands for post cycle therapy. When you take any compound that affects testosterone, your body’s natural production of that hormone may be negatively affected.

PCT is used to bring that natural production back to its pre-cycle level. When you take a SARM, your testosterone suppression will be less than if you were to take anabolic steroids or prohormones, however, there will still be a minor suppressive effect.

I recommend following your bulking cycle with 3 weeks of PCT using Clomid.

This is a brand name for a compound that is actually called Clomiphene Citrate. It is, in essence, a synthetic form of estrogen.

As such it does the opposite to what steroids, prohormones, and SARMs do. Taking Clomid initiates a process by which the body produces more testosterone.

When taken for a steroid PCT, the Clomid dosage is around 50 mg per day. However, because the suppression effect is much milder with SARMs, a dosage of 10 mg per day for 3 weeks will be sufficient.

SARMs Results

SARMs will produce you with some pretty impressive bulking results. However, this won’t happen automatically.

You will also need to be training intensely in the gym, pushing constantly to increase the weight that you are using. In addition, you will need to be increasing your caloric intake by around 500 calories beyond your maintenance level.

Concentrate on lean proteins at a rate of 1 gram per pound of bodyweight.

You can expect to put on between 5 and 15 pounds of mass over the course of an 8-week cycle of Testolone stacks with Ligandrol.

Here’s an example of a guy who completed a 8-week cycle of Testolone Rad 140 and Ligandrol LGD-4033.

Best SARMs for Bulking

As you can see, this guy has put on an impressive amount of mass through his traps, deltoids, and arms while retaining his leanness.

SARMs Forum

SARMs forums allow you to benefit from the experience of SARMs users who have gone before you. This will help you to understand what to expect and what to do to have the best user experience.

When it comes to buying SARMs, forums can also guide you to the best, most reliable online retailers.

There are a number of SARMs forums online. The one that I recommend is isarms.

It features a steroids and SARMs information forum, a SARMs expert podcast, an underground source talk, and a SARMs buyer review forum.

Where to Buy SARMs (Bodybuilding)

SARMs can be purchased legally in almost every country around the world (the exception is Australia). However, they can only be sold as research tools.

As a result, there are many online retailers who know that their target market is bodybuilders. Due to the law, however, they do not promote their SARMs as bodybuilding supplements.

Instead, they present them dryly without any of the promotion that you would expect to see on a bodybuilding supplement website.

Due to the SARMs market being completely unregulated, you need to be very careful about buying SARMs. Many online sellers are dubious at best and you should avoid buying your SARMs from Asia as the quality and purity from that part of the world is highly suspect.

Best SARM Companies to Buy SARMs

There are a few suppliers who have gained a reputation for the quality of their products. 4 of the best suppliers for SARMs include:

  1. ChemYo
  2. Pure Rawz
  3. Swiss Chems
  4. Behemoth Labz

Take-Home Message

If you are serious about bulking up, selective androgen receptor modulators will get you there faster and more safely than using steroids or prohormones. However, you should not take SARMs until you are beyond puberty and have at least a year’s worth of serious training under your belt since prior to that time your natural testosterone production and muscle building potential are still developing.

Make sure that you are also training hard and that you’re eating at last 500 more calories per day than your maintenance level with an emphasis on lean protein. Do these things, and you can expect to pack on between 5 and 15 pounds of mass on your first SARMs cycle.
