No way to know unless you have it tested for the compound or get blood work after using it for a few weeks. Next time stick to Domestic-Supply since they have the best gear and customer service you will find.
bro no one knows... you shouldn't be buying from a source you don't trust anyway.
we have sources here that are trusted and the forum will back you up. don't buy elsewhere and come here and ask if we know what you bought is real. that's ridiculous.
