As a customer you will always be… As a customer you will always be skeptical of purchasing things online. The first time I purchased enduralean from here, the flavor I wanted was not in stock and they reached out to me asking me if I wanted a different flavor. The next time, I had a question and they were fast to respond back not like other places. So that's Amazing customer service.

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!

First Time Customer It was My Supplement Store to the rescue. I was out of my Life Extension Bone Strength Collagen Formula w/KoAct, which I have been taking for years. They had an ample supply and were great with notifications when the items shipped and when they were delivered. I was very satisfied with the whole experience and will use them again in the future.

I guess this is the place to be, congrats. The tracking system has been upgraded in a big way ! Products are class A in order to say the best on the market. Phone communication if needed is always there cause I have used it. Good company, good products and service, what else you expect as customer ? I guess this is the place to be, congrats.
