I have been trying to wean myself off of chinese bathtub products but it's hard when the price is so good. Nolvadex has generally been regarded as one of his "good" products, meaning most people seem to think it is dosed accurately and actually IS nolvadex. But I have never seen a lab test on it, and it is 20mg, so I don't know what the guy is talking about with the 50mg thing. If you can get some legit pharmaceutical-quality nolva, spend the extra couple bucks.
