It is 2:58am and I have just found your question. I have not researched this substance called Sensa yet.
Do a little reading on your own and keep asking others and if you are still dis satisfied with what you know about the product get back to me.
As a doctor and one how have done a lots of reseach in the past, I still like doing drug-safety studies and research on herbal treatments and herbal plants.
I am not putting you off but I am tired. Get back with me.
"As you go, Peace."
