Not unless you're anemic or hypotensive to begin with (and if you're a guy using AAS for performance enhancement, this should not be the case).
I give blood and ride my motorcycle home immediately without issue. No difference in the gym either.
And St Pete: smoking does not reduce RBCs and you seem to be implying. Carbon monoxide merely binds to RBCs and hemoglobin with 300X the affinity of oxygen, which displaces 02 and will give a falsely high reading on a pulse oximeter. So yes, it lowers oxygen transport, but by outcompeting it for hemoglobin binding. And of course then there is the whole COPD aspect...
