Hi all, I’ve been using prime but trying to make a switch since we are ordering for myself and my husband and prime is $$$. Can anyone give feedback on Nexaph tirz30 before I do their preorder that ships in like a week? Their prices and everything looks great but I’m hoping someone can give some reviews on previous testing and quality. Also any refs on NAD+ or GHK-cu resources? My skin is so loose after already losing 65lbs(about 40 to go) and I’m also dealing with a lot of inflammation from an accident that needed a bunch of surgeries. Thanks!!
