The best current new donor bonuses across every major plasma center — ranked, verified, and updated monthly. Start with the one that stacks a referral code.
Plasma centers run rolling new donor promotions that change every month and vary by location. We track them so you don't have to. Here's how the major centers rank this month, with the most valuable stackable offer first. Remember that exact pay depends on your location, weight, and which promotion is running at your specific center, so always confirm before you go.
New donor bonus of $700–$900 across your first 8 donations, plus an extra $50–$100 when you enter referral code U2M3CEACL4 at signup. CSL is the only major center with a public referral code you can stack on top of the new donor bonus. Full CSL bonus breakdown →
BioLife frequently runs the highest upfront new donor promo, often $600–$900. No public code, but some locations honor a "Buddy Bonus" if you mention a referring donor at the front desk. BioLife promo details →

| CSL Plasma | $700–$1,000 | Yes — U2M3CEACL4 | $50–$75 |
| BioLife | $600–$900 | Buddy Bonus only | $50–$80 |

If you're going to start donating this month, CSL Plasma is the most valuable place to begin — not because its base pay is wildly higher, but because it's the only major center where you can stack a referral code on top of the new donor bonus. Everything else being roughly equal, that's free money you can't get anywhere else.
