### ⭐⭐⭐⭐⭐ Strong
*by P***A on March 23, 2025*

I personally love black jack. Gives me tons of energy and I get things done and talk a lot. However if you are sensitive to caffeine I DO NOT RECOMMEND IT! IT IS VERY STRONG AND CAN BRING ON SHAKES AND POSSIBLE PANIC ATTACKS If you tolerate it well it's fabulous.
