Bro you are referring to landmark Nutraceuticals CO Limited from Hong Kong China correct?
I know of this company as I worked in BioChem in HongKong. This company is on the US and European Watch list, from what I hear they don't care if you get your delivery as you already paid, they don't always send the right stuff, and they don't finish the wash completely on some products (sorry dont know which ones).
This is only hearsay from others as I personally don't have any interaction with anything of that nature.
Its always risky so I suggest not considering it. Hope this helps ya.
