It's OK, as long as you aren't taking the laundry list of medications they have. AAS' are not on the list, but isotretinoin is. In fact, they'd love our blood, because of the high RBCs - the most used component.
I am having phlebotomies done weekly (with doc order) as my heritage unfortunately allowed me to develope hemacromatosis. Its been a bitch, and I have been drained.... literally. The years of red meat and AAS, coupled with the genetic mutation did not lead to good iron levels. I am lucky I didnt stroke out.
I'm with DLTH. I was denied last Saturday due to my bp. 178/122. Was roughly around that today at the Dr. Changing my bp meds, also adding hawthorne berry until I can get it low enough to donate. Otherwise I'm going to pull a Valentino for the newer generations .
