#1 Best SARM for Endurance

The best SARM for muscular endurance is RAD140 (Testolone).

Testolone is one of the most potent SARMs for building muscle. It also significantly boosts workout recovery, muscular endurance, and levels of stamina. Users of Testolone universally report having a lot more workout energy during their cycle. The side effects are minimal but may include some suppression of testosterone, interrupted sleep, and mood alteration.

The recommended dosage of Testolone is 5 to 20 mg per day. New users should begin with 5 mg and build weekly throughout an 8-week cycle to 15-20 mg during the last two weeks.

Based on our extensive research, we recommend purchasing Testolone from Sports Technology Labs.

Testolone Summary

Testolone RAD 140

Testolone Rad 140 is a selective androgen receptor modulator (SARM) that was created for the purpose of treating breast cancer and muscle wasting in postmenopausal women. It effectively enhances the body’s natural production of testosterone and also increases lean body mass.

Since it attaches selectively to androgen receptors, it does not carry the sort of side effects that come with anabolic steroids.

Testolone primarily increases lean muscle tissue by enhancing testosterone and human growth hormone as well as boosting other anabolic effects following intense weight training. It may also be able to increase training energy, endurance, and speed while working out.

Testolone is considered to be one of the best SARMs for muscle-building effects but it has also been shown to be effective in fat burning as well.

An initial study conducted on monkeys showed that the administration of Testolone increased their body weight by 10 percent after 28 days of use. Another similar study showed that the negative effects on the prostate and seminal vesicles were significantly reduced by taking Testolone along with synthetic testosterone.

#2 Beginner SARM for Endurance

The best SARM for beginners is Ostarine (MK-2866).

This is a mild SARM that people who are brand new to the use of SARMs will be able to tolerate.
It is suitable for both men and women.

This SARM is beneficial for both bulking and cutting cycles. You will also notice improvements in energy and endurance when you take Ostarine.

Ostarine Summary


Ostarine is an orally-active, non-steroidal selective androgen receptor modulator (SARM ).

It’s considered to be the best SARM for beginners and it is most commonly used during bulking and recomp phases.

In a 12-week double-blind placebo-controlled phase II clinical trial involving 120 healthy elderly men and postmenopausal women, ostarine was shown to significantly increase muscle issues, and improve physical function and insulin sensitivity. [4]

Ostarine selectively binds itself to proteins within the body that are called androgen receptors. 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. [5]

Ostarine is legal, but only for research purposes. It has not been approved by the US Food & Drug Administration (FDA) and as a result, cannot be sold as a dietary supplement.

Ostarine MK-2866 Overview

⭐️ Top Benefits: Muscle growth, strength gain, fat loss
🧪 Form: Liquid, Powder
⌛️ Cycle Length: 6 – 7 weeks
💰 Average Cost: $54.99

#3 Ligandrol LGD 4033

The best SARM for Cardiovascular Endurance is Ligandrol.
Ligandrol has been used for decades to help medical patients combat muscle wasting disease and fatigue. Over that time it has shown to be a safe product with very few side effects.

Some people, however, may experience mild aggression and depression along with increased blood pressure when they take Ligandrol.

Ligandrol has become popular with endurance athletes as a means to boost their cardiovascular endurance allowing them to keep going when they would otherwise have ‘hit the wall.’

Start your Ligandrol cycle with 5 mg per day. If you tolerate it well, increase it to 10 mg in week 4 of your 8-week cycle.

Based on our extensive research, we recommend purchasing Ligandrol from Sports Technology Labs.

LGD 4033 Summary

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 in order 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.

SARMs for Endurance

In addition to their ability to promote anabolic hormone release to increase muscle hypertrophy, a number of selective androgen receptor modulators also increase muscular and cardiovascular endurance.

SARMs are a targeted legal alternative to steroids that allow you to recover more effectively from your workouts.

Rather than boosting hormonal activity, they get to work on the androgen receptors to promote enhanced protein synthesis and resultant muscle repair and growth.

They also significantly increase the energy output of muscle cells to boost endurance levels.

SARMs users find that they have the extra oomph to push through the most grueling workouts, that they recover from their training sessions faster, and that they are able to sustain a consistent cardiac output for longer.

Types of Endurance

Endurance can be divided into two aspects; cardiovascular and muscular.

Total fitness requires that a person have high levels of both!

Cardiovascular Endurance

Cardio endurance involves aerobic metabolism – it is your ability to perform exercises that tax your heart and lungs for a prolonged period of time.

Cardiovascular endurance exercises include running, cycling, and rowing.

In fact, any activity that challenges your heart and lungs to work harder can be considered cardiovascular and this could include some forms of weight training.

Muscular Endurance

Muscular endurance specifically refers to the ability of an individual muscle to perform a high number of repetitions of a movement that takes it through its full range of motion.

This obviously relates to performing resistance exercises in the gym.

However, it can also be achieved with cardiovascular exercise.

For example, if you run for an hour, you are performing repetitions of moving your quadriceps up and down. This is a test of muscular endurance.

At the same time, you are testing the cardiovascular endurance of your heart and lungs.

Best SARMs Stack for Endurance

The best SARMs stack for endurance combines the best cardiovascular endurance SARM with the best muscular endurance compound.

As a result, you should stack Ligandrol with Testolone.

Stacking these two compounds will not only provide you with a massive all-around endurance boost, but it will also help you to get big fast.

Here is how you should stack Ligandrol and Testolone over an 8-week cycle:

Week 15 mg per day15 mg per day
Week 25 mg per day15 mg per day
Week 310 mg per day15 mg per day
Week 410 mg per day15 mg per day
Week 510 mg per day10 mg per day
Week 610 mg per day10 mg per day
Week 715 mg per day 
Week 815 mg per day 

Do You Need PCT for SARMs?

You generally do not need PCT for SARMs. PCT is done to offset the suppression of testosterone that occurs in a cycle.

SARMs such as Ostarine will not suppress testosterone.

There are a few SARMs, however, that do have a suppressive effect. One of them is RAD 140.

When using a PCT for SARMs, you can use a milder form than you would with steroids.

Take-Home Message

Your best bet to supercharge your endurance safely and effectively is to stack the two best SARMs over an 8-week cycle of Ligandrol and Testolone.

You will be amazed at how much more energy and endurance you will get from this stack.
