Cardarine (GW-501516) binds to the PPAR receptor, specifically a group of nuclear receptors (sensors that detect thyroid and steroidal hormones in the body) that initiates the PGC-1a enzyme. This action leads to gene expression, specifically genes that revolve around energy expenditure.
Studies involving GW-501516 have shown to increase the metabolism of fatty acids in rats. It was also shown in the same studies to reduce the odds of obesity despite poor eating habits as well as prevent Type-2 diabetes. Cardarine was also shown to increase HDL (good cholesterol) and decrease LDL (bad cholesterol) in a study using monkeys. The effects seemed to hold true with or without exercise.
The effects of Cardarine are fairly significant and may be a welcomed addition to the stack for a performance athlete. Increased endurance may be the PPAR-RA’s most incredible attribute. Those who use the medication will find they do not tire out as easily and can train harder and longer. The cardiovascular endurance that comes with Cardarine is so strong it has been shown to do away with the cardio issues that surround the popular anabolic steroid Trenbolone. Many who use Trenbolone report breathing becomes a bit more difficult and that cardio becomes a more arduous task. Cardarine seems to negate this negative effect when using Tren.
The effects of Cardarine also help tremendously with fat loss. If nothing else, you’re able to perform your cardio more intensely and longer. Further, it doesn’t carry any catabolic effect that is associated with many thermogenics or fat burners, meaning muscle loss due to use is of no concern. More importantly, GW-501516 has been shown to increase nutrient efficiency. Simply put, you make better use of the nutrients you’re consuming. Those who use the compound will find increased levels of glucose uptake and fat stores reduced.
