Best SARMs for Endurance

Testolone RAD 140

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 over the course of 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.

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 to 10 mg in week 4 of your 8-week cycle.

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 on 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.
