this vendor has listings for really cheap Ket can anyone here vouch for his K or him it looks like his feedback could possibly be fake and hes got listings for K at around 25$ per g..
After looking at their store they have really low prices on everything and also have huge listings.
Sounds like two big red flags waving in your face. Currently looking for a good vendor of s-isomer K myself--let me know if you locate someone and I'll do the same.
