I have a bottle of Erase Pro(old formula), that I have been holding onto till the end of summer approaches. I have never taken an AI before and am somewhat hesitant to take it. I have not had any sort of blood work done showing my test or estro levels. Is there any harm in taking the Erase Pro even though I do not know my Estrogen levels or is it just a waste of product. I have read there is no concern for rebound with any version of Erase and will obviously stop taking the pills if I have any signs of low Estrogen. I am not and never have taken any type of gear in the past so hormones should not be affected by anything of that nature. Thanks.
