A friend in New York ordered pentedrone
from the company that sells ETCATH crystals and he said he received a little bag labelled "ETC" instead of pentedrone. This is more evidence that they are the same thing. Why are they selling the same chemical using 2 different names? This is strange. On their website they say that pentedrone is "legal everywhere" and even if that isn't true, it's still pointless for them to offer it under a mystery name if they're going to claim that it's legal under the original name. Besides, if it is inspected and tested then it will be legal or illegal depending on test results, not on the name they give to it.
The product has been tested and there were no problems with it. My friend has made many purchases from this same company and has had nothing but good experiences, so he has no reason to mistrust them based only on this one issue.
Many reviews of pentedrone are available in threads with that name in the title, so for those who want to know what "ETCATH crystals" are like, just look up pentedrone. To me, it sounds like a very fast-acting speed with short half-life
and serious crash-and-burn effect that makes a person want to redose frequently. Not exactly a health supplement or long term brain-brightener; more like a pro-depressive neuron killer. As we used to say back in the 60s and 70s, "Speed kills!"
