Mne has lasted over months and I'm loving the product I'm not sure if its this or this being combined with my ghrp6 but no breakout since starting the product so I'm happy and will be a customer for life. I also noticed you updated the packaging of this and majestic to green so I'll be ordering soon and might let a friend try a bottle to see if he responds the same as I have. Any thoughts on RPN shirts or wife beaters?
