Primal Labs Heart Zest and CardioRelax AO gave me heart palpitations that landed me in a cardiologist's office followed by prescription drugs!
When I requested a refund of the bottles not opened, the company refused, even though their website claims you get a "full refund, no questions asked."!
I would never recommend this company that has such poor customer service and doesn't stand behind their advertising!
Bottom Line: No, I would not recommend this to a friend
