We cannot speculate on what you have.
Also - you're going to have to slowly experiment with what you have. Kavalactone. That's the one. Without knowing (and the product you have not stating it is worrying) how much is there, you can NOT find a basis to start off of, other than "LOW."
In the future, only purchase product with listed levels of Kavalactone. You may have something super potent (quite unlikely) to barely active (much more likely). However, again no speculation is allowed.
