Here's what I have thus far, in a nutshell........

501516 activates the same pathways activated through exercise, and is effective for fat lose and athletic endurance in both men and women. It is being investigated as a treatment for obesity, diabetes, dyslipidemia and cardiovascular disease. GW-501516 has a synergistic effect when combined with AICAR: the combination has been shown to significantly increase exercise endurance in studies more than either compound alone.

GW-50156 regulates fat burning through a number of widespread mechanisms ; it increases glucose uptake in skeletal muscle tissue and increases muscle gene expression, especially genes involved in preferential lipid utilization.,This shift changes the body's metabolism to favor burning fat for energy instead of carbohydrates or muscle protein, potentially allowing clinical application for obese patients to lose fat effectively without experiencing muscle catabolism or the effects and satiety issues associated with low blood sugar. GW-501516 also increases muscle mass, which improved glucose tolerance and reduced fat mass accumulation even in test subjects fed a very high fat diet, suggesting that GW-501516 may have a protective effect against obesity.

It has been demonstrated at oral doses of 5 mg a day to reverse metabolic abnormalities in obese men and women with pre-diabetic metabolic syndrome, most likely by stimulating fatty acid oxidation.Treatments with GW-501516 have been shown to increase HDL cholesterol by up to 79% and the compound is now undergoing Phase II trials to improve HDL cholesterol. If you are looking to burn fat, increase metabolism, and greatly improve athletic performance no other product on the market today comparable to GW-50156
