It is the Tijuana Mama hot pickles sausage. They've been around for decades, and they still come in the same orange wrapper with a figure is a senorita and it says 400% hotter (used to say 300% hotter). They're widely available at convenience stores, and I do believe they contain ingredients that improve brain function.
I do strongly recommend that you check the expiration date cuz some places may have had them sitting for years. Also make sure the sausage doesn't appear too dry.
