Well Swale says don't use an AI during pct cause is risks the probability of driving estrogen too low. This is what worries me is that 25mg ed of Aromasin can decrease estrogen by 85% correct? Is that not too low? I don't want to lose my damn sex drive ha ha because of no estrogen. What if only 10mg ed was used wouldn't that be about 40% reduction in estrogen and wouldn't that seem better? Someone please explain this too me.
