Red Cross is a bunch of sorry asses that work harder at getting out of work... FACT..
Had you walked into a clinic that is in business with the medical community
(conducting the Therapeutic Phlebotomies) they probably would have taken you with those stats. Getting the doc to sign the papers will eliminate the 8 week waiting period between donations and you can go weekly all the way down to 13
technically.
DONT DO THAT(SEE NEXT PARAGRAPH). I would recommend stopping mid range around 15. You can count on dropping off 0.75 to 1.25 points for every donation depending on hydration levels.
A solid member around here once educated me a bit on the following. Know that shit starts to get out of balance in terms of blood components once you get out of whack and try to bring it down too fast. Iron, hemoglobin, red blood cells, & ferritin are all different red blood cell factors and components that do not replace as equally as they are bled out. Its a difficult concept to understand. I don't think the techs really do either.
All they know is they will bleed you out all the way down to 13 if you let them. Its like there's vampires living in the back... I'd recommend going once a week for 2-3 weeks tops and then back off to every 4 weeks till you get down around 15.
Trust me on this.. DO NOT GO TOO FAST / Youoollll be sooorrrreyyyy....
Once you hit 15 you can probably get away with once every 8 weeks if you are on 200mgs test or less... Just paying it forward as one did for me.
