Cardarine (GW501516) Guide: Dosage, Results, & More! (2021)
Cardarine, otherwise known as its research name GW501516, is a research chemical that has garnered the eye of many athletes around the globe.
While it’s often lumped in with SARMs, Cardarine isn’t technically a SARM—it’s a PPARδ receptor agonist, developed to improve cardiovascular health in those suffering from diseases.
Recently however, many body builders and athletes have been using Cardarine to shred fat and enhance endurance—does it work, though?
In this article, we’ll cover the results, dosage, cycle guidelines, and take a look at what the clinical research has to say about Cardarine so far.
What is Cardarine? (GW501516)
Cardarine is often placed in the group of SARMs, although this isn’t entirely accurate—while Cardarine may be similar to SARMs, it is not a SARM.
Cardarine, sometimes known by its research chemical name GW-501516, is a peroxisome proliferator-activated receptor delta agonist that was initially developed to help treat metabolic and cardiovascular diseases. [R]
Recreational users soon discovered that Cardarine could also be used to drastically increase endurance and accelerate fat loss, though.
In fact, according to most cycle logs and anecdotal evidence, Cardarine can be used as a powerful cutting agent, to lose fat rapidly, and to seriously improve endurance levels.
Overview of Pros & Cons
Before we look at the various dosages, cycles, stacks, and effects on the body that Cardarine has, let’s first give a quick overview of it.
- Enhance Muscle Endurance
- Accelerate Body Fat Loss
- Increase Energy Levels
- Promote Lean Muscle Gain
- Improve Insulin Sensitivity
- Healthier Blood Lipid Profile
- Not Entirely Risk Free
- More Research Should Be Done
- Increased Rate of Cell Death
- High Dosages May Increase Cancer Risk
The biggest concern many people have with Cardarine is its potential to cause cancer, but as we’ll explore later in this article, the study which came to this conclusion gave lab mice an incredibly high dosage that almost no human would ever take, for a very long period of time. [R]
All in all, Cardarine is a fascinating research substance which body builders can use to keep muscle on a cut, promote accelerated fat loss, and more.
Legality of Cardarine
While researchers at the FDA have still not given this substance the “okay” for human consumption, it’s still 100% legal to buy and sell online.
Currently, this supplement is classified as a research chemical, meaning that people can buy it for “personal research” and it’s completely legal.
Our recommended SARMs vendor is currently Science Bio—we wrote a full review of them there, and we recommend you give it a read first.
How Does Cardarine Work?
Shortly after ingestion, Cardarine works by binding to the PPAR Delta receptor, and signals the liver to draw energy from fatty acids. [R]
Typically, your body draws energy from blood sugars (glucose), however by switching the preferred source to fatty acids, fat loss is accelerated.
In fact, it isn’t uncommon for people using Cardarine for bodybuilding to report losing over 10-15 pounds from one 8-12 week cycle.
Unfortunately however, Ligand Pharmaceuticals, the same company that created Ligandrol, abandoned Cardarine research in 2007, so there isn’t very much clinical data regarding the fat loss effects of this substance.
Cardarine vs. SARMs
One of the biggest misconceptions that a lot of people have, is that Cardarine is somehow a SARM—this is actually not the case.
Rather, it is something known as a PPARδ receptor agonist, which is a class of products currently under research for their potential cardiovascular health benefits.
That being said, Cardarine is often sold alongside SARMs, and many body builders find that stacking it with SARMs such as RAD 140 can help accelerate fat loss, and makes for a great cutting cycle.
While Cardarine hasn’t technically been approved for human usage, many of body builders report losing large amounts of fat on Cardarine cycles.
In fact, it isn’t uncommon for users to report losing 10-15 pounds of fat from a 12 week cycle of Cardarine, even at a relatively low dose such as 10 mg.
Benefits of GW-501516:
- Accelerated Fat Loss
- Enhanced Endurance
- Great Cutting Agent
- Improved Blood Lipids
The most impressive benefit of Cardarine, is its ability to increase endurance in users. In fact, one study found that lab mice that took Cardarine increased endurance by over 200% more than placebo. [R]
Accelerated Fat Loss
Perhaps the biggest benefit of this supplement is its ability to rapidly accelerate fat loss in the human body (and in mice, too).
Shortly after ingestion, Cardarine is absorbed into the blood stream, where it binds to PPAR Delta receptors, and signals them to use fats for fuel.
This can help increase energy levels, improve cardiovascular health, and can result in a lean, shredded physique—in fact, Cardarine is one of the best SARMs for shredding (even though it’s technically not a SARM).
One of the greatest benefits of Cardarine is drastically increased stamina and endurance—it accomplishes this feat by changing the energy source that your body uses from carbohydrates to fats.
This leads to enhanced muscle endurance (both smooth muscle and skeletal muscles), as well as higher energy levels, better stamina, and much more.
Is it any wonder that Cardarine is considered one of the best legal steroids on the market right now? This supplement is amazing for body building.
Great For Cutting
Cardarine is one of my favorite supplements for bodybuilding, due to its ability to encourage lean muscle retention while also losing body fat.
Studies show it does this by binding to PPAR Delta receptors, and then signaling the liver to use fats as fuel, rather than glucose in the blood.
Some researchers have theorized that this may add stress to the liver, but most anecdotal reports suggest Cardarine is not only safe, but extremely effective.
Improved Lipid Panel
One of the more surprising benefits of using Cardarine is that it can even help improve blood lipids, such as triglycerides and cholesterol.
In fact, according to studies, Cardarine, as well as other PPAR Delta receptor agonists, may lower blood lipids and prevent cardiovascular damage. [R]
Combine this with other studies that suggest it’s a potent lean muscle builder, and can improve recovery, and you’ve got yourself a wonder drug.
Many users experience phenomenal results from Cardarine, particularly body builders trying to decrease their body fat percentages and get lean.
The Cardarine results pictured above are from a video by Greg Doucette, who is an International Federation of Bodybuilding & Fitness Pro.
“It was crazy. I was so much faster,” he said about using Cardarine in a biking race. “I can’t point out how much improvement that it made.”
He also added that it helped him in the gym, too. “My endurance, set after set after set after set was easy,” he said. “I could’ve kept going.”
Many other users experience similar effects while on Cardarine, reporting enhanced performance, faster fat loss, and insane endurance effects.
Cardarine Dosage & Cycle Guidelines
Clinical trials conducted on humans used Cardarine dosages ranging from 2.5 mg to 10 mg per day, although some people have used up to 20 mg.
Here are the Cardarine dosage guidelines:
- Beginner: 5 mg per day
- Intermediate: 10 mg per day
- Advanced: 20 mg per day
For example, an intermediate dosage of Cardarine would be 10 mg per day, or half a dropper of the Cardarine (GW-501516) from Science Bio.
The effects of Cardarine are dose-dependent, meaning that if you take a higher dosage of Cardarine, you will experience more fat loss, endurance, and energy, as well as potentially more side effects.
Bulking & Cutting Stacks
Some users take multiple SARMs at once, which allows them to experience even more muscle growth, fat loss, and enhanced athletic performance.
Cardarine (GW501516) is generally best suited for a cutting stack, as it allows users to burn fat rapidly, and enhances endurance.
|Sample Bulking Stack||Sample Cutting Stack|
|Cardarine – 10 mg per day||Cardarine – 20 mg per day|
|Ligandrol – 20 mg per day||Ostarine – 25 mg per day|
|YK11 – 10 mg per day||Andarine – 50 mg per day|
While Cardarine is generally considered a good SARM for cutting, it can also be used to do a lean bulk, as it prevents fat gain even when in a minor caloric surplus, according to many cycle logs and user reports.
Cardarine Side Effects
According to the Australian Department of Health, as well as clinical studies, there are no known side effects of taking Cardarine. [R]
While there are very few known short term side effects of Cardarine use in humans, more research should be done on the long term effects.
One common question people have relates to a study which found that Cardarine caused cancer growth to develop in organs of lab mice.
It has been noted, however, that the mice in this study were given this PPARδ receptor for roughly 2/3 of their life straight (with no breaks).
With this in mind, the evidence that Cardarine could cause cancer in humans is shaky at best—no bodybuilder is going to dose Cardarine daily for two thirds of his life (roughly 50 years straight).
Where to Buy Cardarine
If you are like many other body builders, and want to get the best results in the gym that you possibly can, you’re probably wanting to try Cardarine.
If you do decide to try Cardarine, be sure to get it from a high quality source, like the ones we outlined in our SARMs for Sale article.
