Found they had solid pricing on NAD+, and then saw they had Re*a GLP. Compared to my usual/VERY reliable (Penguin), I ran side-by-side and for 2 500mg NAD+, 1-30mgRe*a, it was $166 vs $291!!!! That was with discounts for both vendors. Southern’s documentation, testing and safety is TOP of the class and they’ve become my new go-to and HOME! Both products VERY legit VERY solid! Give em a shot (pun intended)! 😬
