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.

I received a container on Killer Labz… I received a container on Killer Labz Noxious pre-workout that was clumpy, pasty & in chunks. Didn't look good or new. Looked like it was exposed to hear or past expiration. Couldn't tell because container did not have an expiration printed on the label which was odd & not common. Was skeptical to use for consumption due to the nature of the product. Not a pleasant experience for a first-time shopper. Need Help in rectifying this issue ASAP!

My supplement store had a Memorial Day sale My supplement store had a Memorial Day sale so I ordered a lot of stuff. The label was created on 5/30 and it's 6/9 and I still haven't received my order. This is my first time ordering through this website and it's very disappointing. They didn't even pack my order until about a week after my purchase I'm also missing an item that they never told me about By far the WORST experience I've ever had buying supplements! I will never buy from My Supplement Store again!

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!

KOCKED THE F&C! OUT REVIEW I’m a 6X Champion Boxer that trains almost and literally every day (1 day off) I run in the mornings 4-8 miles a day. In the afternoons and evenings and nights, I train an additional 2.5 to 3 hours a day. KNOCK THE F&C@ OUT helps me sleep and it assists in recovery for my body after intense and long workouts. It’s an awesome and very helpful supplement. The recovery effect from this supplement allows me to come back to my workouts with optimal strength, speed, endurance, and stamina.
