What does 'third-party tested' actually mean?

It means an independent laboratory — not the seller — has analyzed the product and issued a Certificate of Analysis verifying its purity and identity. This is the single most important indicator of a reputable supplier.

How do you rank these brands?

We score each supplier on third-party lab testing, verified purity, shipping speed and packaging, pricing, and customer reputation. The ranking reflects the overall balance of these factors, not any single metric.

Do you earn a commission from these links?

Yes. When you click through to a supplier we may earn a commission at no extra cost to you. This never affects our rankings — our scoring criteria are applied consistently to every brand we review.

What's the difference between the top brands?

All five publish lab reports and ship quickly. The differences come down to price per mg, catalog breadth, bulk discounts, and support quality — which is exactly what our comparison table breaks down.
