My ex gilr was a phlebotomist and I used to donate where she works. For some reason they never asked about steroids but said you couldnt donate if you have taken growth hormone or ever shared a needle for any reason, or injected intervenously with any illegal drug. Steroids arent growth hormone or injected intervenously. I doubt you have to worry about your blood messing someone up because they do indeed check the blood for irregularities, not specifically for steroids but for anything that just isnt right. Toward the end of my last cycle I went for a donation and was told I couldnt donate cause the last donation I had given showed certain proteins in my blood to be too high. Having donated for over a decade previous to this with no problem of this sort ever Im positive it was due to the gear. My point is they dont check specifically for steroids or ask you about steroids (just GH) but they do test the plasma and any irregularity will cause them to simply not use it. By the way if you loose or gain over 10lbs in like 2 weeks I think they make you give them an explanation why. They told me I could donate again after the levels of whatever protein it was in my blood went back to regular but I havent been to see.

you could they dont test it for steroids but its not a good idea , u dont know what effects it will have on a sick person .. actually one of the question they ask u is if u ever taken steroids or any other performance enchancing drug
