Nov 7, 2016 Lapsing into layman-speak, aas use is assumed to "thicken" blood to some extent, possibly to the extent of making it dangerous for the aas user, clots, strokes, heart attacks, etc. Sometimes suggested as more of a threat from Boldenone use than other aas. Donating blood is often advised as a means of minimizing this effect, but, how to do? The Red Cross has different ways to donate blood, with different imposed time delays between repeat donations. You can donate blood at various places, but I am assuming Red Cross rules govern all? So . . . . best for a worried aas user to do the simple whole blood every 56 days, or the "platelets," or something else?
