Who sent me L-arginine?

I have been meaning to ask this. A month or two ago, I received two amber glass vials of what was labeled as 1.5g of L-arginine from the UK. I have not order anything from the UK recently. It is also strange that they are 1.5g vials of L-arginine, when my normal dose is 1g. That means I got 3 doses shipped to me internationally. That's just silly.

Since I get shipments sent to me for testing all the time, I figure this might be one of those. Perhaps they were labeled as L-arginine to fool customs. It just seems weird shipping that small of an amount of an amino acid.

So does anyone remember sending me two amber vials from the UK? If it is Anthrax, I would like to know about it before opening the vials.
