Anyone have any experience with selling plasma?

I did this for cash as a college student almost a decade ago. I think I got $20 (cash) per donation and could donate 2x a week. An extra $160 a month as a college student goes a long way.
I remember that I would have to get weighed and have my temperature taken before donating. There was always a long wait, and the waiting room was filled with college kids and people who looked like they were homeless or a step away from it.
The actual procedure isn’t that bad. It feels like donating blood, except the blood that gets circulated back feels a little cold. No biggie.

Thanks @Likeradar! An extra $160 a month would go a long way…Hmmm…

I haven’t done it, but I went to check it out a couple years ago. I remember that you were more or less required to go back a few days after your first visit. For some reason, I wish I could remember why, they could only use the donated plasma if they got a second batch from the same person within a certain amount of time. Thus, you got paid more for the second visit each week than for the first.

Be sure to read all the literature they give you. I declined after I read it, because it said long term use can deplete the calcium in your body. It also said that some people experience a burning sensation from the saline they use to re-introduce the blood.
