I'm affiliated with the company, so let me just point that out first. It is 100% legit and we've had the compound for quite some time, but have waited to release it. We've tested this since last October, so I can assure you that you are getting what the label is claiming. BTW, I have used Epistane and will begin using our product tomorrow to judge any differences, if there are any. I know many wouldn't consider me the ideal person to give any feedback, since I am involved with EST, but I figured some feedback is better than none.
