Cardarine is considered one of the most effective endurance supplements on the market. It’s also ideal for athletes looking to increase their metabolism and burn fat more efficiently, as it targets the androgen receptors that stimulate glucose to the muscles.
Cardarine (also known as GW 501516) was originally developed by Ligand Pharmaceuticals and British pharmaceutical company GlaxoSmithKline Plc. It was designed to prevent prostate and breast tumors and later to increase HDL and reduce LDL cholesterol in the body.
Cardarine is an effective SARM for
- Increased Endurance
Cardarine is classified as a PPAR (Peroxisome Proliferator-Activated Receptor), so is not a traditional SARMS, though it’s properties and characteristics are identical to a SARM. Early research at The Robarts Research Institute in Ontario, Canada showed Cardarine to be an effective PPAR and have a positive effect on insulin resistance. 
One research study reported that Cardarine caused cancer in rats.  What is important to highlight from this study is that the rats were given 240x what is considered a normal dose. They were also given it every day for two years, which is much longer than the 4-12-week cycle that is recommended.
Cardarine is a specific SARM and can be used for;
The cutting phase involves lowering your body fat and is an important phase for those that for example, have the abs there, though they are hidden under a little spare tire.
To cut body fat, you need to create a calorie deficit. It’s remembering that we all require different amounts of calories. Our demands for energy based on the food we consume differs depending on our age, weight, height and activity levels. Research has shown that cutting should be done with small or moderate deficits (i.e. around -500 kcal) to avoid loss of muscle mass. 
The quality of calories consumed during this phase is really important. This means eating the right balance of protein, fats and carbohydrates. Research at McMaster University in Hamilton, Canada has shown that eating a high-protein diet during cutting phase is important to preserve muscle mass. 
It’s also important that you are providing your muscles with a strong stimulus via your training. If you just eat a calorie deficit without resistance training and focus more on cardio training, you may lose more muscle than intended. Research at The University of North Carolina has shown strength training is important while cutting to avoid muscle loss. 
What makes Cardarine such an effective supplement during the cutting phase is its ability to raise the natural metabolic rate. This is because Cardarine targets the androgen receptors that stimulate glucose to the muscles. Research at The University of Queensland in Australia has shown Cardarine promotes fat burning in muscle while increasing metabolism. 
Furthermore, research has shown that PPAR’s like Cardarine regulate glucose metabolism and insulin sensitivity. This is because they allow the body to use fat as energy, which allow athletes to train intensely and be more efficient at losing body fat. 
Cardarine is considered among users as “the ultimate endurance enhancing supplement.” This is due to its ability to allow athletes to train at high levels of intensity during their workouts and break through plateaus. It also allows them to recover faster, which is why it has gained the reputation it has.
One of the most prominent animal studies done with Cardarine showed that mice using it showed exceptional stamina and could run twice the length of other mice. 
Cardarine targets and enhances the ability of muscles to use energy more efficiently, which allows athletes to achieve a higher level of performance without putting excessive demands on the body compared to those who are not using it.
This is because Cardarine helps to prevent oxidative damage on the heart. Researchers at The Mayo Clinic College of Medicine in Rochester, Minnesota found that Cardarine increased bioavailability of a precursor to nitric oxide, which helps to improve blood flow and therefore allow the body to function more optimally. 
Cardarine Side Effects
There have been no reported side effects with Cardarine in the last 20 years.
10-20 mg per day is a sufficient dose. 10 mg a day is aimed for endurance, and the higher dosage is better for fat loss, though when starting out begin with a lower dose of 5 mg and adjust accordingly depending on how your body responds to it.
It has a 16-24-hour half-life, so you can take a 10 mg dosage once per day, or if taking 20 mg per day then I recommend splitting your dose into two, taking one dose every 10-12 hours.
It is recommended to be used for 4-12-week cycles with 4-6 week break cycles.
SARMS are such an innovative and popular supplement amongst athletes, bodybuilders, powerlifters and cross fitters. Cardarine is an upgraded, safer and alternative version to anabolic steroids. It’s formulated and created to target specific androgen receptors in specific areas in the body without the side effects commonly associated with its predecessor.
Disclaimer: SARMs are banned by WADA and most other global sporting organisation for both in-competition and out-of-competition use. You should NOT use them if you are competing in any such sanctioned sport as it a prohibited class of anabolic agents. Please check with local doping agencies for the latest information.
