The big news is that Jarrell Williams has been found positive for Cardarine GW501516 in his test on March ahead of his huge fight against Anthony Joshua in June. So here is all the information on what exactly Cardarine is.

What is GW501516 – Cardarine?

Cardarine, also known as Endurobol, has been in development since 1990, and is now one of the most popular SARMS because of its ability to burn excess fat, improve recovery, and dramatically increase muscle endurance to 150% by supplying them with twice as high levels oxygen. Without any harmful side effects discovered over the last 20 years, it is no wonder that Cardarine has become a legend in the world of sports and athletics. This obviously can be seen in the recent case of Jarrell Miller.

Cardarine (GW5015016) is used by elite athletes, mainly to improve stamina, as it is felt during the first 40 minutes after taking. It gives you enormous levels of energy, improving muscle stiffness and muscle efficiency by 150% . This means you will make your work shorter but more intense or longer without feeling tired. Reduces recovery time – meaning you can train every day while you are taking GW501516. Cardarine will quickly melt the fat without affecting the muscle mass.

In Short, Cardarine;

  • Provides an increase in energy levels to 150% without being a stimulant
  • Versatile – can be combined with almost anything.
  • Can be used for fat burning or muscle growth, will speed up your results in both cases
  • No side effects, liver toxicity or testosterone suppression have been reported.
  • There is no need for therapy after a cycle.


The ability of Cardarine GW501516 to relieve unwanted fat has become almost legendary. Like growth hormone, Endurobol generates proinflammatory markers in adipose tissue and reduces the activity of genes involved in lipogenesis. This means that your body will be able to block the formation of fatty acid chains and store them as fat.

A study of scientific reports published in 2015 states that Endurobol works on PPAR beta cells, making the body use only its own fat as a source of energy. Activation of these separate genes in the body has the potential to burn body fat at such an alarming rate that some people see Cardarine as a “solution to obesity.”

There are absolutely no undesirable side effects found during the last 20 years of research, and muscle loss was extremely rare during the study.

Endurobol stimulates the intake of glucose and skeletal muscle tissue. It burns fat by stimulating the oxidation of fatty acids. It is offered as a potential treatment for obesity because of its ability to quickly lose fat. Also, Cardarine increases HDL with an average of 79% (good cholesterol) and reduces LDL (bad cholesterol) in ongoing Phase II trials.

This makes it perfect for priming during a steroid cycle because it eliminates any side effects from the build-up of bad cholesterol.


Not to say that there are none, but no side effects have been seen in the past 20 years by anyone who studies it, Endurobol has been tested in healthy individuals, in simulated “real-life” habits (such as drinking alcohol, stimulant drugs, and use of tobacco products). It is not certain whether there are consequences, but there is no published study to indicate otherwise.

This makes Cardarine usable for long periods of time. In some studies, there are even signs of turning diabetes, obesity, dyslipidemia and many other diseases.


Unlike the popular claim, GW501516 does not cause hepatic cell damage. It is known to affect healthy liver function and stimulate faster healing of skin and muscle tissue.


What makes Cardarine distinctive is that it can be used for almost anything, clearing fat, increase muscle mass or post cycle therapy.

The most common way to use Cardarine is a triple stack, including LGD 4033 or MK 2866 + S4 (Ardarine) . So take advantage of everything, endurance, burning fat and increasing muscle mass.


Cardarine  stimulates genes in Androgen receptors responsible for the use of fatty tissue as energy. In this way the body switches to fat as the main source of energy, which contributes to their accelerated burning. Another unique feature of the Cardarine is that it boosts oxygen and blood circulation to muscle and tissue by 150 to 175%, allowing you to use your muscles optimally (doing more repetitions or cardio without scratching). Also, increased blood circulation will help burn the hard-to-reach fat you mentioned around your abdomen, because in principle there is not enough blood in your body, in other words your body will already be able to use them as a source of energy. If you want an even better fat- burning effect, Andarine is the best combination with Cardarine, because while Cardarine stimulates the body to use fat as the main source of energy, Andarine can minimise lipoprotein lipase, an enzyme that causes accumulation of fat. This automatically means that with Andarine the fat will stick you hard. There is also 33% of the strength of testosterone, which means you can also pick up pure muscle.
