Do you ask to test before buying?

[verbal]

I know its a stupid question. I haven't bought many pills that I haven't trusted the supplier or have heard about before. So I haven't had the chance for this to happen. But has anybody ever gotten a bad reaction from your supplier for requesting to test the pills before buying? Just curious..

No problem to test; you only need a minute scraping off the pill to test it, and you can do it right in front of them! Promise to buty at least the one pill if it turns out alright though!

If there's someone that WON'T let you test, then you can assume they've got something to hide anyway, so you're probably better off without their products...
