I made a one time purchase and all of a sudden you guys are trying to go into my account again without asking to do so. Totally greasy work practice

Didn't have what I wanted and 50 bucks of clumps is not what I ordered. My first time buying and probably my last. Another failure of a quality control.

Did not receive the 15% discount. Called and even spoke with the guy and he never credited me nor called me back. Will not be recommending or reordering.

Besides the products of being some of the best in the market, I get the best advice and the best consultation for each type of supplement that is used for my specific needs

Black stone customer service sucks. Horrible experience, you reach out to them and they don’t respond, you have to message them three times before they give you a response that doesn’t even answer your problems. I can’t review the products because I never received them. Do not buy black stone products from them, they will rip you off.
