Tweeti know you are on the older end of the range dirt but it does come back rather quickly once you are able to start back up. the only thing that comes to my mind that doesnt raise rbc at all is ment (trest ace/e). if you are prone to estro issues then it does cause issues their but as far as rbc and other health markers legit ment does not impact them at all. it is strong as hell also, like a super tren with none of the side effects
