Because of the physical changes that legit EQ causes... read gh15, others testimonies, I would pick EQ in a heart beat. Remember this has to be Vet grade or at the very least made by a respected ugl.
While 1-Test Cyp for sure causes a more phenomenal increase in strength there is a reason you don't see it on every source board being discussed and that is because it is simply inferior to what is more readily available. They should have made a 1-Test propionate or acetate or pp or some faster acting ester as it would cause a much more potent effect as we can see in its oral counterpart M1T.
EQ ALL THE WAY!
