Anytime I'm dealing with EQ, Hemoglobin is a concern. Deca will not eaise HB too high on its own, but EQ could. For guys tunning higher dosed EQ cycles, I suggest that when they notice their HD is getting high, go in a give a pint of blood. It fixes itstantly. Signs I usually get are red face, easily winded, tired more often, to the point of falling asleep mid day, when worse. When you see these things coming on, go donate and you'll feel better the next morning.
