A real, donor-tested breakdown of pay rates, new donor bonuses, and the two very different referral programs - so you can pick the right center and claim every bonus you're owed.

I've donated plasma at both Grifols (Biomat USA) and BioLife, so here's the no-fluff version: they pay in the same ballpark. In July 2026, both pay roughly $50–$75 per donation for regular donors, and both run new donor promotions worth $600–$900 (sometimes more) in your first month. BioLife often edges slightly ahead on the new donor bonus; Grifols rewards twice-weekly donors harder with its split-pay structure over the long run.
The most important difference isn't the pay - it's how each referral program works, because that's where people leave money on the table. Grifols uses a referral code (you enter it in DonorHub or use an auto-fill link). BioLife uses your name - there's no code to type; the new donor just tells the front desk who referred them. Get that one detail right and you claim an extra bonus at either center.
Here's the full head-to-head for 2026. Exact pay varies by location, your weight, and which promotions are running, so treat these as realistic ranges rather than guarantees:
| Feature | Grifols | BioLife |
|---|---|---|
| Regular pay / visit | $50–$75 | $50–$80 |
| New donor (1st month) | $700–$900 | $600–$900+ |
| Referral program | $100 code (DonorHub) | Name-based Buddy Bonus ($50–$200) |
| Referral mechanic | Enter code before 1st donation | Give referrer's name at 1st visit |
| 2nd visit of week pays more | Yes — significant split | Moderate |
| Payment method | Prepaid debit card | Prepaid debit card |
| Appointments | Walk-ins welcome | Required (shorter waits) |
| Mobile app | Basic (DonorHub) | Good (My BioLife Rewards) |
| US locations | 300+ | ~260 |
| Lapsed donor reset | 6+ months | Varies |
For the full per-tier breakdown at each company, see our Grifols pay chart and BioLife promo code guide.
Both Grifols and BioLife pay on a weight-tier system, because heavier donors can safely give more plasma per visit. Here's the realistic per-donation pay for regular (post-bonus) donors at each:
| Weight Range | Grifols / Visit | BioLife / Visit |
|---|---|---|
| 110–149 lbs | $40–$55 | $40–$60 |
| 150–174 lbs | $45–$65 | $45–$70 |
| 175+ lbs | $50–$75 | $50–$80 |
The one real structural difference: Grifols front-loads the second donation of the week harder than BioLife does. At Grifols, your second weekly visit can pay 20–40% more than your first, which rewards twice-weekly donors. BioLife's per-visit pay is a bit flatter but often starts higher for new donors. If you can reliably donate twice a week long term, Grifols' split-pay structure is slightly more generous on the regular-donor side.
This is where most people make their money, and it's close. Both companies offer an elevated rate across your first several donations:
| Stage | Grifols | BioLife |
|---|---|---|
| New donor 1st month | $700–$900 | $600–$900+ |
| Referral on top | +$100 (code) | +$50–$200 (name / Buddy Bonus) |
| Realistic 1st-month total | $800–$1,000 | $650–$1,100 |
This is the part that confuses the most donors, so here it is plainly. The two programs are claimed in completely different ways:
Enter the referral code in DonorHub (or use an auto-fill link) before your first donation. $100 to the referrer after the friend completes 2 donations within 180 days.
No code to type. When staff asks who referred you at your first visit, give the referrer's full name. The Buddy Bonus loads once you complete your qualifying donations.
If both centers are near you, it comes down to two things: which has the better new donor promotion this month, and which referral you can actually claim. BioLife frequently posts a slightly higher new donor bonus and requires appointments (shorter waits); Grifols pays more for your second weekly visit and has more locations nationwide.
The smart play: pick the center with the better current offer near you, and always claim the referral - the code at Grifols, or the name at BioLife. Over time you can even claim a separate new donor bonus at each, as long as you never donate at two centers in the same week.

Grifols pays a $100 referral bonus. Auto-fill the code (zero typing) or enter it manually in DonorHub before your first donation.
