No it’s true that anything can be poisoned even your beer leaving it on a table. Usally your supplier and the people in the culture will know what is good and where to get it... it’s only a concern I would have getting stuff from random people.
Your advice is terrible, I'm sorry, it's just awful. Your advising the use of drugs as 'safe' which present various dangers, you're advising eyeballing MDMA to know what's right, and now you're basically saying to trust your supplier.
This is all very poor advice.
Get chemical test kits, use drug testing services where they are available, be cautious.
And if you read my comments again I actually advice against most drugs. I’m arguing against comparing mdma with ecstasy pills which is pretty much impossible for the dealer or any to figure out what is inside but in regard to mdma crystals is much easier to reason about a clean product when you take others experience around you and looks and taste knowing it... but yes there is always a risk like leaving a beer unattended. This could be different but In my part of the world we can usally trust what we are provided.

Which is pretty terrible itself, powders and crystals can be just as adulterated as pills. Relying on sight and taste to tell what you've got is very unreliable.
