No you fuck head the manufacturer should be testing the Raws, at the point of production, but let me explain something so you fucktwots can understand.
You can look up how testosterone is synthesized from DHEA online, and that's exactly how it's done in China. You get a final crystalline product that you try and that is our base hormone. It is esterified after that.
Process is pretty simple, and you get testosterone base. The final product that you collect is test. Then you clean it up a bit. But what you get is test. There is a minimum purity with which it is made. You can't have testosterone that is not testosterone.
But this shit isn't regulated, so you are at the mercy of the facility that is making your Raws. Sometimes you get some shit that is impure but there's nothing you can do. it's not dangerous just impure. Some raw manufacturers are better than others, but they can all fuck up because it's not regulated. And any UGL that has a decent sales volume has to buy Raws and ship out product they don't have time to send everything they have out for analysis, whether that's the Raws or the finished product. And cleaning up the raws is not practical to do.
Like I said if you give a flying fuck about any of this stuff why are you even ordering from UGL's? It makes no goddamn sense. Bypass that shit and get the Raws yourself and if it makes you happy you can analyze that shit til you cum all over your cat.
