By MacAdam Stafford · Plasma donor & referral researcher · Updated June 14, 2026
I'm MacAdam Stafford — a plasma donor, Michigan State University information-science student, and the person who built and runs PlasmaPromoCode.com. I am not a doctor, nurse, or any kind of medical professional. I don't pretend to be.
What I am is someone who actually donates plasma and got frustrated early on by how hard it was to find accurate pay information. Plasma centers post their rates inconsistently, promotional bonuses rotate monthly, and the numbers you'd find online were often months or years out of date. So I started keeping my own notes — per-visit pay at the centers I visited, bonus schedules I saw in the app, reports from the r/plasmadonation subreddit, and data from other donors I connected with.
That personal spreadsheet eventually became this site. I'm the one who researches, writes, and maintains every page here. No ghost writers, no AI-generated filler, no "team of experts" I've never met. When something changes — a new bonus month, an updated pay tier — I update it myself because I'm tracking this data anyway for my own donations.
I also build referral and data tools as a side interest. PlasmaPromoCode.com is one of them: a practical reference site that does one thing well — keeps real, current pay and bonus data for plasma donors who don't want to be misled.
Plasma centers don't make their pay rates easy to compare. CSL Plasma, BioLife, Grifols (Biomat USA), and Octapharma all vary by location, weight tier, and donor status — and the numbers can swing by $20–40 per visit depending on where you are and what promotions are running.
When I was a first-time donor trying to figure out how much I'd actually make, the information I found was vague, outdated, or straight-up wrong. I found blog posts citing 2021 rates in 2024. I found sites confidently quoting "$50 per donation" as a flat fact — which isn't how any of this works.
I built PlasmaPromoCode.com to be the resource I wished had existed when I started. The pay charts here reflect real data — rates I've personally encountered, corroborated by community reports and direct checks against center apps. When I'm not certain about something, I say so.
Pay figures come from a combination of: my own donation history and receipts, corroborated reports from the plasma donation subreddits, data published in center apps and promotional emails, and periodic direct verification by calling or visiting centers. I do not publish a number I can't corroborate from at least two independent sources.
Bonus schedules and promotional pay change monthly — sometimes mid-month. I review all pay charts at the start of each month and update them when I see changes. The "Updated" date on each page reflects the last time I verified the figures, not just the last time I touched the HTML.
Pay varies by location — sometimes significantly. A CSL Plasma in Michigan may pay differently than one in Texas or Florida. The ranges I publish represent real reported rates, but your specific center may pay more or less. Always confirm with your local center before making plans based on these figures.
This site covers pay, bonuses, and eligibility questions (medications, tattoos, diabetes, weight requirements) from a practical donor perspective. Nothing here is medical advice. For questions about your personal health and plasma donation eligibility, talk to the medical staff at your plasma center — they're the right people to ask.
Where possible, I link to the plasma center's own published information. I cite community sources like r/plasmadonation and r/CSLPlasmaReferrals when they're relevant. I don't cite "industry reports" I haven't actually read, and I don't repeat numbers just because another website posted them.
This arrangement does not affect what I write. I'm not going to tell you BioLife pays more than it does because they have a higher referral bonus. I track this data for my own donations too — I need it to be accurate for the same reasons you do.
