Kent's suggestion to contact the person you got it from would seem to be a good start...
The original purpose of this enhancer appears to be to flavor
tobacco, but it looks like some people may use this as another option for DIY mixing their own
ejuice..
I am not very familiar with this product.. but if you do a search on this forum for seedmans, or flavor enhancer you may find what you are looking for.... that is if the person you got it from can't provide that answer for you.
Hopefully this gets you closer to what you were looking for.
