Most Alani pre-workout powders and single-serve energy sticks provide about 200 mg of caffeine per serving/stick, according to the product descriptions.
Listings include standard warnings: keep out of reach of children; consult a doctor if pregnant, nursing, or if you have medical or thyroid conditions; products contain caffeine and are not recommended for children, those sensitive to caffeine, pregnant women, or nursing mothers.
Energy-stick descriptions commonly list added B vitamins — specifically pantothenic acid (B5), pyridoxine (B6) and cobalamin (B12) — and some listings also mention added biotin.
