My Supplement Store - 100% satisfaction guarantee! My supplement Store was very caring when I called a number of times regarding my order. I had received the wrong vitamins and had the package sent back through USPS so I could receive the correct vitamins. USPS is investigating where the package is currently. My Supplement store has resolved my issue and I am very happy with this Company and I will continue ordering my vitamins through them!

I made a order on Feb I made a order on Feb. 17th. On Feb. 27, I had to contact to see where my order was cause I have not received it! They said they was out of stock on the order, but never contacted me to tell me or anything, plus took my money! Very unprofessional! Will never use again!

Incorrect item was shipped to me Incorrect item was shipped to me. I was told the warehouse personnel made the mistake and item should be re-package and returned. This is UNACCEPTABLE! Since this was your problem either the correct should be shipped to me or i should receive a refund credit. I emailed a message to your company stating this...no response back.

Overall very satisfied with my experience Overall very satisfied with my experience. From the beginning to when my two supplements arrived. Looking forward to purchasing again once I run out. Thanks!

Just started taking the product Thank you for making available your product of potassium nitrate in capsule form. You are one of the few companies that make this valuable NO precursor available to the public. I am taking it now to help with nitric oxide supplementation to improve arterial and venous blood flow. So far the formula seems to be agreeing with my system. I will pass on any positive results after taking your product for awhile.
