Still sounds shit, that is how it goes mate:
Step 1: the product is not intended for human consumption
Step 2: you buy it anyway and smoke it (mind you it may be in salt form so let say you freebase it)
Step 3: it doesn't work
Step 4: you cannot even return it.
Step 5: you feel frustrated and therefore you sue them for scam
Step 6: their lawyer ask how do you prove the product is not what they claim it to be.
Step 7: you cannot defend your position by saying it did not have an effect on you. you were not supposed to consume it in the first place.
Step 8: you cannot say it didn't work for the x, y, z controlled biological experiment you were performing because simply you were not performing any. If you were actually needing it for experiment you would have a more reliable source from the beginning anyway, like Sigma-Aldrich
Step 9: you can only send it to mass spectrometer but still the identification is not that accurate. mass spectrophotometry cannot distinguish between 5-meo-dmt, 4-meo-dmt, 5-meo-dmt, 6-meo-dmt etc. They can make any other compound that show very similar or identical to 5-meo-dmt in such an analysis.
Step 10: you would not even go around suing them in the first place these things would cause you unnecessary stress, waste of time and waste of loads of money. You would decide to cry a bit over the lost money in the first place and forget the whole thing.
The customer testimonies mean nothing really, I can write hundreds of them, so can you I presume. How do you know they are valid?
The best thing is to search further/ask further on the internet about this vendor and the product they sell. Other people must have bought from them, better ask them.
Alternatively, just give them a go and judge for yourself if spending some money is not an issue. Then report back to us. We'll make sure they run out of stock pretty soon, hahahahaha
