Some mice at low dosage got cancer. The other study was at a higher dosage and no cancer was discovered.
Cancer
There has been many forum comments expressing the concerns of GW501516 and it’s relationship to cancer and tumor development. The hypothesis for this controversy stems from GW’s ability to improve Angiogenesis in the body at an extremely high rate and the rate of cancer growth in the colons of lab mice.
This is a common occurrence among endurance athletes and children going through adolescence. Scientists had speculation that if there were tumor cells active in the body, that they would be especially susceptible to angiogenesis and cause the tumor to grow at a much faster rate.

Other Name(s): Cardarine, GW50156, Endurobol

What is GW 501516 (Cardarine)?
GW 501516 (or Cardarine), is a research chemical developed in the 1990s to prevent and cure tumor formation in the colon, prostate, and breasts. Studies done in the early 2000s have found that GW 501516 and other PPAR agonists have also been able to stop metabolic disorders such as obesity and diabetes through specific gene expressions.
As research continued to grow, bodybuilders quickly caught on to GW 501516, calling it “the ultimate endurance enhancing supplement.”
Plus, Cardarine’s ability to burn off excess fatty tissue, enhance recovery, and dramatically increase endurance has made this product a staple in every athlete’s cycle and PCT. With no harmful side effects found in the past 20 years, no wonder why GW 501516 has become a legend in the world of sports and athleticism.
Let’s take a closer look…
How It Works
GW 501516 is is a PPARδ agonist and NOT a SARM, but does work in very similar ways. In this case, GW 501516 targets the androgen receptors that stimulate glucose uptake and skeletal muscle tissue. Currently, it is being suggested as a potential treatment for obesity by rapidly melting through through what’s called “fatty acid oxidation“.
Also, Cardarine is said to increase HDL by an average of 79% (good cholesterol) and decrease LDL (bad cholesterol) in current Phase II trials.
These help increase your HDL levels from an enhanced expression of the cholesterol transporter ABCA1.
The Benefits of GW 501516
The benefits of Cardarine seem to be endless, both in medical science and in the gym. Many studies have been done on GW 501516 showing numerous positive effects during trial, despite minimum side effects.
That is part of the reason why Cardarine has recently become so popular.
Below are a list of the most powerful benefits that you could experience while taking a cycle of GW 501516 (compiled from much research and study)
The Ultimate Endurance Supplement
GW 501516 is literally the best it gets when it comes to endurance, energy, stamina, and performance enhancement of any kind.
It is used by elite athletes for a reason, from cyclists to elite bodybuilders. In fact, WADA has even addded GW 501516 to their list of banned substances because of it’s competitive advantage.
You can expect insane levels of intensity in the gym, shorter recovery times, and be able to bust through plateaus like never before.
Also, the energy you get from Cardarine is not experienced as jittery or anxious. It’s not a stimulant, and you won’t crash hours later.
In fact, many users even report feeling an overall sense of well being and calmness.
Some of the other benefits include:
Rapidly melts fat and NON catabolic.
Provides noticeable results on the first dose.
The ability to run for as long as 8-12+ weeks.
Is versatile and can be stacked with anything.
Can be used while cutting OR bulking.
No side effects, liver toxicity, or suppression have been reported.
No need for a PCT
Cardarine: The Cure for Obesity?
THE PRIMARY ROLE is GW’s ability to rid the body of unwanted fatty tissue and it has become almost LEGENDARY. The chemical compounds in this particular PPAR agonist functions in differentiation of adipocytes.
Much like growth hormone, GW 501516 generates proinflammatory markers in adipose tissue and decreasing the activity of genes involved in lipogenesis. This means that the body is able to block fatty acid chains from forming and being stored as fat.
A study from Scientific Reports published in 2015 stated:
“GW501516 acts on PPAR beta cells that exclusively use body fat as energy in the same way the body would when going through “starvation mode”.
The study is quoted stating: “physiological and pathophysiological functions of PPAR and generated novel strategies to treat metabolic diseases”.
The activation of these particular genes in the body have been seen to burn body fat at such an alarming rate that it is being coined “the cure to obesity”.
There were absolutely no adverse side effects detected in the last 20 years of study and it was extremely rare to see muscle wasting at any point during the research.
Cardarine’s Effects on Muscle Fibers
The 2015 study by Wei Chen, PhD and his colleges has also found that dramatic increases in the PPAR gene in slow twitch muscle fibers increases oxygen usage and greatly increases endurance. The enhanced endurance was seen in lab mice with a normal oxygen supply and those with oxygen restrictions which provided significant evidence that GW501516 targets and enhances skeletal muscle endurance and recovery time to a supraphysiological level.

A study titled “A metabolomic study of the PPARδ agonist GW501516 for enhancing running endurance in Kunming mice” stated that BCAA were spared during trials of intense exercise which allowed the mice to have a greater rate of recovery in muscle tissue and neurotransmitters.
These rats had even lost weight while maintaining a high fat diet, suggesting it could potentially prevent obesity and help manage weight regardless of diet or lifestyle.
Side Effects
Not to say that there are none, but in the last 20 years no side effects have been seen by anyone studying the drug.
GW501516 has not only been tested in healthy subjects, but also those with simulated “real life” habits (such as drinking alcohol, stimulant narcotics, and the use of tobacco products). It is uncertain if there are long term ramifications, but no research has been published stating otherwise.
This is what makes Cardarine so incredibly popular and usable over long periods of time. In certain studies, there have even been signs showing the reversal of diabetes, obesity, Dyslipidemia and many other diseases.
Liver Damage
In contrast to popular belief, GW501516 doesn’t promote damage of liver cells. The chemical has actually been known to promote healthy liver function and faster healing properties to the skin and muscle tissue. In essence, you will not heal rapidly like Wolverine from the X Men movies, but you will shorten the your recovery time from scratches, blisters, and injured muscles by a significant amount.
Cancer
There has been many forum comments expressing the concerns of GW501516 and it’s relationship to cancer and tumor development. The hypothesis for this controversy stems from GW’s ability to improve Angiogenesis in the body at an extremely high rate and the rate of cancer growth in the colons of lab mice.
This is a common occurrence among endurance athletes and children going through adolescence. Scientists had speculation that if there were tumor cells active in the body, that they would be especially susceptible to angiogenesis and cause the tumor to grow at a much faster rate. Since 2004 many experiments have been done to prove this hypothesis, but so far, all of them have been largely unsuccessful.
A study published in 2004 by the American Association of Cancer Research stated that PPAR agonists have:
…Shown to have no effect on the proliferation of colorectal cancer cells and “…under normal culture conditions, PPAR activation has no effect on cell growth”.
Keep in mind that this study was done in rats given amounts of 400 mg a day and was abused and ran for hundreds of weeks to top it all off. Time and time again this study has been refuted and shown to be deeply flawed and inaccurate.
In a 2008 experiment done on human breast cancer and colon cancer cells, not only did the PPAR agonist GW 501516 prove to be safe for use, it has proven to inhibit cancer cell growth. The National Institute of Health has confirmed without a reasonable doubt that GW 501516 inhibits a multitude of cancers in human cells.
Over a decade of research studies on human PPAR beta (the primary target of GW) has only proven a decrease in cancer cells with extended use (up to two years). The confusion for these previous allegations of cancer growth were from results published in 1996 and have long since been abandoned due to new clinical research. The chemical compound has been dosed in human PPAR for a number of years and has only provided positive results on cancer treatments, liver function, and metabolic efficiency.
In all of the human studies done so far, there were no noticeable side effects at all while running GW.
