How we source and verify our data

PlasmaPayFinder is an independent directory. We're not owned by or affiliated with CSL Plasma, BioLife, Grifols, Octapharma, KEDPLASMA, or any other plasma company. Our goal is to help donors compare pay, bonuses, and hours honestly — which only works if the data is sourced and current. Here's exactly how we handle it.

Where the data comes from

Every listing is built from primary sources:

• The companies' own websites — each chain publishes its center locations, addresses, phone numbers, and hours. We read those directly.
• Published new-donor offers — advertised first-month bonuses come from the company's own site or a specific center's page, quoted and linked.
• Center operators — once a center claims its listing, its details come straight from the people who run it.

We do not copy data from other directories. If we can't trace a fact to a real source, we don't publish it.

What "verified" means

Every pay figure and policy on the site carries a source and a "checked" date, so you can see where it came from and how fresh it is. We label each one by how it was confirmed:

• Published for this center — the amount is stated on that specific location's page.
• Chain-wide advertised offer — the company advertises it across locations; the exact amount near you may differ (we mark these with an asterisk).
• Verified with the center — confirmed directly by the operator through a listing claim.

How often we update

Plasma pay and promotions change often, so a stale number is worse than none. We re-check published offers on a monthly cycle and stamp each listing with the date it was last verified. When you see an old date, treat the figure with extra caution.

Why we can't promise an exact payment

Plasma pay depends on your weight, your location, whether you're a new or returning donor, and whatever promotion is running. The numbers here are the best published comparison available — always confirm the current amount with the center before you go.

Corrections and claims

Run a center and something's wrong or out of date? Claim your listing to correct it — it's free, and every submission is reviewed by a person before it goes live. Anyone else can flag an error by emailing corrections@plasmapayfinder.com.

Advertising and featured listings

Some listings may be labeled "featured" or "sponsored" — those are clearly marked. Payment never changes how we report pay rates, and never changes a ranking claim like "highest-paying." Those rankings are based only on current, sourced data.

Who maintains this site

PlasmaPayFinder is built and maintained by Riverdale Products LLC, trading as RiverdalePro, of Oakdale, New York — owner John Hauser. We publish who we are so that the sourcing standard above is attributable to someone. RiverdalePro's own verification record lists its stated identity, owner, location and live projects.
