You should be OK - no cops will show up, and i doubt your name is even on a list.

I have in the past ordered prescription drugs without a prescription over the internet from overseas sellers. I have gotten the same empty envelope with the same stamp - "RECEIVED UNSEALED",

I got as freaked as you - a couple days later i contacted the company and they sent another bottle. 2nd bottle made it just fine.

Made many transactions since without issue.

Im ordering from Nirvana a little later this month.
