Cardarine 10 from XtLabs packs 10 mg of GW501516 (Cardarine) in each capsule or tablet. Even though people often call it a SARM, it’s not—it's a PPARδ receptor agonist. Each bottle usually has 60 capsules. The compound boosts fat metabolism and helps your body use energy more efficiently. It’s non-steroidal, and it sticks around in your system for about 16 to 24 hours.

People in the bodybuilding and fitness world reach for Cardarine to push their endurance, burn more fat, and tweak their cholesterol, especially when they’re cutting or doing lots of cardio. It shifts your metabolism so you burn more fat for fuel, but you don’t get any of those androgenic side effects.

Most folks start with 10 to 20 mg a day—one or two capsules. Some take it all at once in the morning, others split it between morning and evening, usually about half an hour before a workout. Run it for 8 to 12 weeks, then take a 4-week break. There’s no need for PCT since it doesn’t mess with testosterone, but it’s smart to start low and see how your body reacts.

What’s good?
 You get a big boost in stamina and fat loss without feeling wired. It helps hold onto muscle even when you’re dieting, and it can improve your cholesterol (raising HDL, lowering LDL). It’s non-hormonal, so it plays well with things like Supertest or Arimidex.

But—there’s a downside. 
WADA bans Cardarine because high doses gave rodents cancer in lab tests. Since it’s only available through underground labs, you never really know what you’re getting. Human safety data is pretty thin, so the long-term risks are a big question mark.

Side effects? 
So far, limited human studies show few problems at 10 mg, but animal research points to possible liver toxicity and cancer risk. Some people get headaches, nausea, or feel tired. Definitely keep an eye on your liver enzymes. If you’ve had cancer before, don’t mess with it—and if you’re using it, regular bloodwork is a good idea.
