Opinions - Is this pure MDMA? - Safe to take?

[thealmassi1]

This may seem like a dumb question, but SWIM's dealer has ecstasy pills and (what he says is) pure MDMA. Based on SWIY's experiences, do SWIYs think that the pure MDMA is actually pure?

SWIM's friend was saying how it's impossible to know unless SWIM's dealer knows the maker of the substance, and SWIm doubts he knows the maker. My friend was saying how the other compounds can be very harmful and how the pure MDMA is probably just as sketchy as the ecstasy pills.

The pure MDMA is in a white little oval-shaped (aka vitamin shaped) pill.\

Like the pic, except it's white. (The dealer's E pills are round and red)

Should SWIm trust his dealer? Do the positives outweigh the risks to try the "pure" pill?

Thanks.
