If you're looking for the best selective androgen receptor modulators to improve muscular endurance and cardiovascular endurance levels, this is the guide for you.
I've been using SARMs for almost 13 years now (yes that long), so have tried almost everything myself, from SARMs to anabolic steroids and designer steroids, too.In this article we'll cover:
- Different Types of Endurance
- SARMs for Muscular Endurance
- SARMs for Cardio Endurance
- Stacks for Better Endurance
- …and more
So if you want improved athletic endurance, either to break some personal records, or just for the fun of it, then sit back, and read our article on the BEST SARMs for endurance.
Types of Endurance
First off, we have to explain something. Before we get into the best SARMs to improve endurance, you first need to understand that there's more than one type of endurance.
The two types of endurance are:
- Muscular Endurance – This is also known as anaerobic endurance, which breaks down glucose in the blood stream without oxygen. It's mainly for short spurts of intensity, but done over a certain duration.
- Cardiovascular Endurance – This is the most obvious kind of endurance, and it's what most people think of when they think of endurance. This is aerobic endurance, which is the ability to encourage glucose metabolism with the aid of oxygen.
Obviously, both forms of endurance are best, but you will have to pick which type you want, because the best SARM for you will vary depending on the TYPE of endurance you want.
Best SARMs for Endurance
When most people think of endurance, they think of cardiovascular endurance, not necessarily muscular endurance. So, we'll focus on that first.
1. Cardarine (GW-501516)Here are the benefits of Cardarine:
- Significant Increase in Endurance [R]
- Insanely High Energy Levels [R]
- Great for Fat Loss & Muscular Strength [R]
- Improve Stamina in the Gym & Treadmill
- Mild Increase in Lean Muscle Mass [R]
- Lower LDL (Bad) Cholesterol Levels [R]
- Many Other Benefits
What makes Cardarine such a powerful compound to increase endurance? The secret lies in its ability to improve mitochondrial biogenesis, your cellular energy production mechanism.
In short, Cardarine literally improves endurance on a cellular level, allowing you to train harder, with increased endurance, better stamina, and super intense workouts.
I remember when I first took Cardarine, it was insane how fast it starts increasing stamina, it literally started on day one. I remember I hadn't done any cardio in years, and I just had a spurt of energy so decided to go for a run. I ran a 7 minute mile, after zero cardio.
It also helps you recover faster, and is great on a cutting cycle. It's okay for building muscle, but it REALLY excels when you want to improve your endurance.
2. Stenabolic (SR-9009)
Stenabolic is another one of the best SARMs for endurance – and while it doesn't have a huge impact on building muscle mass, it's great at shredding body fat and stopping muscle wasting on a cut or caloric deficit.Here are the benefits of Stenabolic:
- Significantly Increase Endurance [R]
- Far More Energy Compared to Baseline
- Great for Cutting Cycles & Fat Loss [R]
- Easy Way to Boost Athletic Performance
- …and more
Stenabolic is classified as a PPAR Delta Receptor agonist, which means it's not the best to increase muscular endurance or increase muscle mass, but it's GREAT for cardio. Almost as strong as Cardarine (GW-501516) but not quite.
It's also great to lose fat. By encouraging fatty acid oxidation and increasing insulin sensitivity, it helps to limit glucose uptake, leading to less fat even with the same calories.
3. Testolone (RAD 140)
Now… RAD 140 is probably my favorite SARM of all time, not to mention an amazing SARM for muscular endurance. The muscle mass you pack on with RAD 140 is insane.Here are some benefits of RAD 140:
- Drastically Improve Muscular Endurance [R]
- Extremely Potent Anabolic Effect
- Rapidly Pack on Lean Muscle Mass [R]
- Amazing At Burning Excess Body Fat
- Builds New Muscle Cells [R]
- Reduces Post Training Fatigue
- …and more
If you want to have more muscular endurance, muscular strength, and just have more energy overall, Testolone (RAD 140) is one of your best bets. It's amazing at building lean muscle, and the rate you shred fat is insane compared to other SARMs.
Best SARMs Stack for Endurance
Based on my own experience and anecdotal evidence, the best SARMs stack for endurance consists of RAD 140 and Cardarine. This will not only burn fat and enhance muscle gains, but drastically improve athletic performance and overall endurance.
When I first started taking this stack, I noticed a huge boost in energy almost immediately, in addition to burning fat and decreasing post training fatigue, plus extra muscle growth.Here is the best SARMs stack for endurance:
- RAD 140 (Testolone): 15mg/day
- Cardarine (GW-501516): 10mg/day
- Cycle Duration: 12 Weeks
- PCT Protocol? Yes
RAD 140 is the strongest selective androgen receptor modulator in my experience, with a 90:1 anabolic ratio, so it has a huge binding affinity for androgen receptors. In a nutshell, this means it will shoot your muscular endurance and athletic performance through the roof.
Cardarine, or GW-501516, isn't a SARM, but is the best research chemical for cardiovascular endurance by far. It's been clinically shown to double your cardiovascular output.
In summary, these are the three best selective androgen receptor modulators for improving your endurance: RAD 140, Cardarine, and Stenabolic. If you do cycle them, don't do it for a super long period of time (just 8-12 weeks is fine), and take the recommended dosage.
Keep in mind both these compounds have a short half life, so they will start to kick in and change your body, muscle strength, and energy very quickly.
If you do want to buy one of these SARMs, we urge you to buy it from our verified list of SARMs companies. Since so many companies these days are known for selling fake stuff, we decided to make and maintain a list of the best, highest quality, verified vendors.
