I never talk about other sources in a specific way but for as long as I have been doing this and long before we ever had our own thing going some of these eastern euro guys kill me with the stuff they say and do. They openly buy votes and reviews on almost every review board, then send a reshipper a few products so they can be listed in the u.s. domestic sections to, this would be fine if the intention was not to fool the newer guys into thinking they were a domestic source. Then when they ask, why is my pack taking a month, your listed in the dom section? The answer is always we are international and this isn't amazon or whatever other cliché source nonsense they decide to regurgitate. I seen a vet on a review board the other day saying how he would never use a domestic source, only the euro guys because they have pharma qc standards and automatic equipment. I say that is nonsense, they are from countries with no real hygene standards, they can say they own pharma factories all they want, They never can seem to prove the fact. More likely they are in a barn half filled with goats out in the middle of Bulgaria where nobody will ever bother them or know, but they can perpetuate the myth that they are set up like Pfizer because nobody will ever challenge it!!
