where are you coming up with each bottle has to last 30 days? i dont get it... so every single person has to dose it the same? NO each bottle does not guarantee thirty days... thats like saying every vial of test is guaranteed this or that... well, do not some people run it lower than others? the sweet spot for sr9009 is 30 mg per day... noone forces you to dose that, you can run it however you like..
