I have nolvadex(tamaxofin) and its from novo I'm pretty sure which is one of the biggest drug companies, they have novo everthing, novo-amoxacillin,novo tylenol, and I got a sealed bottle so I know it's legit, but the shit tastes like candy, I can suck on a pill for about a minute and it tastes sweet, but once the outer layer is gone it gets a real shitty taste like tylenol or something, but if you take it and don't suck on it it tastes sweet.
