1. Twice a week for about a year or 1.5years
2. Depends on your weight. I was 150lbs. The more weight you have, the more you can be taken. I got 25 first in the week and 30 the second I think it was.Highest was 30first35secondtime. You can only donate 2x within a 7 day period and 3 days in between the 2. So Monday and Wednesday is ok I think I did, mightvary at your place. In order to get the 2nd higher payment, it has to be in the same week. Saturday is STUPID busy FYI
3. I went to a place called ZLB Plasma. Looks like a crackhouse or some %%** with the people waiting outside. It was just the wait takes about 2 hours duringpeak time. All the materia: needle, plasma container, bloodspinning thinger, tubing, saline, is all brand new in packaging and sterile. So risk of %%** islower than you think
4. Scars? Its small and barely noticeable. Mine was there for awhile, but has since mostly near null unless someone obviously inspecting super duper hard.
Be prepared to wait. Be prepared to drink water ahead of time when you donating each time. Make sure you protein or something level is up(they check forsomething, forgot which, I just avoided that by eating chipotle or a nice meal before). More water you drink, more faster you donate, just don't get to thepoint that once they stick you, you gotta piss. They deduct you if you gotta piss during it and they gotta use a new needle to restick you. My place checkedyour water level and another nutrient, because its to see if you could pass out during if its low.
I'd do it again if i was bored and had time. I did it during college student days. I just studied/read books while waiting and in the plasma chair. Youwill also find out who are better stickers than others, so stickers suck and aren't as smooth.
