Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of CLA by GNC Pro Performance AMP Advanced Muscle Performance
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
None of the active ingredients could be matched to our evidence database, so intended use can't be graded.
Why this rating?
- None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Every active ingredient lists its own amount on the label.
Why this rating?
- The label discloses an exact amount for 1 of its 1 active ingredient.
- No proprietary blends here — you can verify the dose of every single component.
None of the active ingredients could be matched to our interaction database.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
None of the active ingredients could be matched to our safety data.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.
