What is Cardarine (GW501516)?
Cardarine is a lab compound. Its code name is GW501516. It comes as a tablet.
It was made in the 1990s by GlaxoSmithKline and Ligand Pharmaceuticals. It was later dropped from drug work after long-term animal studies raised concerns.
People often group it with SARMs. It is not one. It acts on PPAR-delta, a receptor found on cells. A receptor is a docking point on a cell.
What researchers study it for
- How it switches PPAR-delta. Labs study how it turns on the PPAR-delta receptor in cells.
- Burning fat for fuel. Studies look at how cells break down fatty acids for fuel.
- Sugar uptake in muscle. Labs measure how muscle cells take up glucose, a type of sugar.
- Endurance in lab models. Studies track endurance and muscle fibre changes in lab models.
What you get
One bottle of 60 tablets. Each tablet holds 10 mg of Cardarine. Study notes list 10 mg a day for weeks 1 to 2, then 20 mg a day. Notes say it does not act on androgen receptors, so no PCT is listed. It is often put in a stack with SARMs such as Ostarine (MK-2866), Andarine (S4), LGD-4033 or RAD-140.
How to store it
Keep the bottle in a cool, dry place. Keep it away from direct light.
