Who was testing my Elixir?

Hello,

This past winter a gentleman accepted an elixir of Salt and Lizard. (the properties of Fortify, Blood, Healing, and Body) It would have a black cat on the label. The deal was that as this was my first one, he could have it as long as he reported back to me of it’s exact effect. However, I never heard back, and have lost an entire notebook since last festive which contained the name of who I loaned it to. It’s possible they simply didn’t end up drinking it yet, but if this is the case I would like to know. Thank you for getting back to me as soon as possible.
