right on indeed.
First off... I would be willing to bet that any DNP you might have is powder... and not crystal. Even if people SAY it is crystal... I don't think it is... I"m about 99.5% sure of this.
If you got it in the US, I'm 100% sure of it. If you got it internationally... I'm just about 100% sure.
A good way to test would be to open a cap... the DNP Crystal powder will sink in a cup of water... immediately. DNP powder will float for a bit (eventually... all DNP will sink -- but crystal sinks immediately).
