GW501516

Also known as: Cardarine

PPAR-delta agonist

What is GW501516?

GW501516, also known as Cardarine, is a synthetic compound classified as a PPAR-delta agonist. It falls under the category of fat loss and metabolic peptides, primarily researched for its potential to enhance metabolic processes and promote fat oxidation. Developed in the 1990s, GW501516 has garnered attention for its ability to influence energy metabolism and improve endurance.

How It Works

GW501516 functions by activating the peroxisome proliferator-activated receptor delta (PPAR-δ), a type of nuclear receptor that plays a crucial role in regulating fatty acid metabolism and energy homeostasis. When activated, PPAR-δ enhances the expression of genes involved in lipid metabolism, leading to increased fatty acid oxidation and improved glucose utilization.

Mechanism of Action

The activation of PPAR-δ by GW501516 promotes a shift from carbohydrate to fat as the primary energy source, which can be particularly beneficial during prolonged exercise. This metabolic shift not only aids in fat loss but also supports endurance and overall physical performance.
