Yea, if it's legit it should be good to go. There are fakes of it floating around so just know your source and you should be fine. I haven't personally tried them but heard good things about them.
If you haven't personally used them, you can't really vouch for them, can you?
Since ORD, most UG's haven't been able to get quality powders.....
EC is no exception to this.
Over on William Llewellyn's forum we were talking about them, and most people who have used them have all said the same thing.
Their quality isn't that great, but you could make that same claim about any number of UG's.
