KVK Tech is a heinous methylphenidate manufacturer. I don’t know what they are doing, how much they are profiting by the subpar corners they are cutting but it is heinous! And CVS is killing us by almost exclusively using this horrific company. It is as if I took a street drug that was laced with rat poison, and I have been taking methylphenidate for 20 years without a problem until KVK Tech became the cheapest maker of this ADD medicine, and thus CVS jumped at the the opportunity. They don’t care. The quality is just heinous.
