Purity - Tips to judge MDMA w/out testing kit, please!!

[jester1]

Hello all,

SO SWIM's friend has a friend of a friend who claims to have MDMA in powder form for sale.
SWIM's friend says his Friend vouches for the guy.
SWIM trusts his friend but since this connection isn't someone his friend knows, he is wary of the product not being pure.

SWIM's question to the more knowledgeable is: How can SWIM judge the quality by eye? Is there any thing to look for? Appearance, taste, consistency anything at all that could tell SWIM that the powder isn't pure MDMA?

*Normally, SWIM would just buy a small amount and try it to see if it's legit. BUT SWIM is leaving the area in a couple days and will only have one shot..
**SWIM would also normally test it but his testing kit is on the way in the mail. And far as SWIM knows the regents can only test for the presence of a MDxx agent, not for MDMA itself. Right?

SWIM would buy about 3-4g's if it is indeed pure, so there is considerable money involved. Please help!!! Thanks to all for their time.
