I did for a period. It kinda sucks because if they mess something up you don't get paid. Sometimes you have to wait a while and it makes it not as worth the time. The pay generally goes down after your first month promo is over
Still, its worth trying out and was good time for getting some reading done. It really depends how well your center is run
I never had any medical issues or side effects, except that alcohol would hit me like a truck the days I donated
The whole premise of it a is really icky and you are being exploited in a major way. The people working there are also not paid all that well AFAIK. You'll notice that the centers tend to be in low income neighborhoods. And while they say you are "doing a great thing" and helping people with rare diseases, you are really helping them turn huge profits as the specialized medicines they make from the plasma are very expensive for the patients as well.
I had the best time with grifols/biomat. I also tried biolife (decent) and octapharma (bad)
When you're promo is up, you can switch to a different center for their promo but you must wait one week in?between.
The plasma centers make medicines from your antibodies and shit. Technically you aren't selling your plasma, and it is a donation, but they are Just compensating you for your time. That's the loophole I guess
Idk why blood banks don't pay except for a $10 amazon gift card or a tshirt here and there. Maybe they just have enough public goodwill and there is still enough altruism left in this world
