Used by athletes and fitness enthusiasts for over 20 years, Cardarine may be one of the most well-known non-steroid performance-enhancing compounds. This well-studied research product has a reputation for significantly improving Endurance. Also known as GW501516, this compound was banned in Olympic sports in 2009 because of its performance-enhancing capabilities. Read on to find out why you may want to include this fascinating product in your research.


  • Enhanced Endurance and stamina
  • Provides maximum fat burning efficiency 
  • Limits fat storage
  • Decreases recovery time
  • Lower LDL cholesterol
  • It may help maintain heart and arteries


It's common to see Cardarine referred to as GW501516, GW1516, GSK-516, and Endurobol.

Sometimes described as a SARM, Cardarine (GW 501516) is actually a PPAR-delta activator as opposed to a SARM, which are selective androgen receptor modulators. Its characteristic of selective binding is the reason we will classify it in our research as a SARM.

To understand how Cardarine can enhance our Endurance, we need to understand what the PPAR delta gene's activation does to our bodies. PPAR activation is linked to increased energy, muscle tissue building, improved endurance, and lower lipids in the blood.


By binding to the PPA Receptor and activating the PPAR-delta pathway, Cardarine has been shown to:

1) Improve endurance and stamina thanks to its ability to activate a process causing muscle fibers to increase oxidation. More oxygen in the muscles means longer, more intense workouts.

2) Decrease body fat. Cardarine takes part in a process in which the body uses stored body fat as energy.

3) Improved liver function. Through the PPAR pathway, Cardarine helps promote the liver to use fatty acids instead of glucose. This process can reduce the amount of sugar in the blood and reduce the risk of insulin dependence.

4) Better blood cholesterol. Human studies have shown Cardarine can lower the bad LDL cholesterol and increase the good HDL cholesterol.

5) Healthier heart and arteries. Studies with mice have shown that Cardarine can prevent oxidative damage to blood vessels and reduce arterial tissue inflammation.


The use of Cardarine and specific dosages are based purely on anecdotal evidence from researchers in the SARMS community, and 99 Purity does not condone its use other than for research purposes.

Users in the community report effective dosages of 10 mg to 20 mg daily. A protocol of 10 mg per day for the first week with an increase to 20 mg per day for the rest of the cycle is common.

With a half-life of over 12 hours, once per day dosing is sufficient and should ideally be taken one to two hours before exercise.

Responsible use of Cardarine has allowed it to become known as a safe alternative to anabolic-androgenic steroids and other performance-enhancing products.

Limit cycles to 12 to 16 weeks and stack with other SARMs for best results.

Cardarine Stacking

Try stacking Cardarine with Ostarine (MK2866) while running a cutting cycle. Being on a calorie-reduced diet to lose weight can burn muscle and drastically reduce your energy. Ostarine will help preserve your muscle gains, and Cardarine will aid muscles with more efficient use of oxygen to keep your energy maximized.

Cardarine also stacks well with LGD-4033 and Rad 140 when bulking is desired.

On its own, GW 501516 does not need PCT (post cycle therapy), but protocols may be necessary after stacking with other SARMs, especially for longer cycles. Buy Clomiphene and Tamoxifen for your PCT here at 99 Purity.

Cardarine can work quickly due to its immediate actions on muscle tissue oxidation – its indirect ability to tell the muscles to use more oxygen. Of course, you will need to experiment for at least 3 to 4 weeks to see benefits like fat loss and improved cholesterol values.

Still wondering where to buy Cardarine? Here at 99 Purity, we have the purest and most potent Cardarine for sale and the best SARMs prices available.
