Just had my first donation today after being gone for a few years.

What are the best and least busiest days and times to go into the Octapharma in Van Nuys, California to donate??

Mine is coming up in the next couple weeks and I’m curious, I wanna time my propanol accordingly!

So does it depend on how much water I have to how many milliliters I give? The last few times they said I'm in the middle group of donating. I've never been in the middle group before.
