HelloPharmacist Scorecard of GW 501516 Extreme by Mass Genetics
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: cardarine, a research compound being investigated for potential effects on athletic performance, blood sugar, and weight. The capsule also contains microcrystalline cellulose, magnesium stearate, and silicon dioxide as inactive ingredients (binders and flow agents).
Does it work?
Insufficient evidence
The evidence we hold does not establish whether cardarine is effective for athletic performance, diabetes, or obesity—all three uses are rated as having insufficient reliable evidence to rate. This is in part because cardarine is not an approved medication and has not undergone the human trials needed to prove it works.
How safe is it?
Some data gaps
Cardarine is not approved for human use, and animal studies linked it to cancer. The safety data advises against use during pregnancy and while breastfeeding due to unknown safety in humans and serious toxicity concerns.
Because cardarine has not been adequately tested in people, adverse effects in humans are not well characterized. Talk with your doctor or pharmacist before taking this product.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. However, because cardarine is not an approved human drug and has not been thoroughly studied, unknown interactions with medications are possible.
Discuss this product with your doctor or pharmacist before combining it with any medications you take.
The bottom line
Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.
Cardarine is a research chemical without FDA approval and without proof it is safe or effective in humans. Animal studies raised cancer concerns.
If you're considering it for athletic performance, blood sugar control, or weight management, talk it over with your doctor or pharmacist first—they can discuss whether it's right for you and what risks it may carry.
