Hey I figured I would share my experience so far with us customs and powders. So a couple weeks ago I ordered some raw test powder nothing crazy 100grams got tracking and everything for it. It's been sitting at customs since april 1st so my supplier told me i should contact customs to see whats up so i figured alright. Talked to the guy he said he has to verify the contents of the package so he asked whats in it I told him it was l-carnitine powder vitamins or whatever and he said thats kind of what we found and theyre just waiting to have the guys field test it tomorrow. They normally come once a week to test packages with powders in them he said and they said once they test it theyll release the package tomorrow and update traking. I know some people waited 30 days to receive their powders before or had their packs sit at customs for a while. But I would imagine they only test for ur basic narcotics and explosive chemicals and what not and havent heard of too many powders being seized or anything. I'm not going to stress about it for now but def going to clean house after tomorrow if it doesn't update. It's going to a po box. I'll keep you guys posted and let you know how things go.
