Hard to say really. You could look at it both ways. You could say well..your DHT levels are really low already and you're fine, so lowering them more probably won't hurt. Or you could say well, since your DHT levels are low, your body probably won't like having almost nothing left to work with, as opposed to having at least 30% left from normal to use.
Everyone reacts differently, theres really no way of knowing unless you take it
