The largest US network by centre count, and the one that publishes a donor referral code openly.
At least 110 pounds, which is 50 kilograms. This is a federal requirement, not a centre preference. No more than twice in any seven day period, and never twice in the same two day window. That means a minimum of 48 hours between donations. A medical history review and a physical examination by a responsible physician on your first donation day, and at least once a year after that.
