Is Legion Pulse Stim-Free good for beginners?
Legion Pulse Stim-Free suits evening trainers and the caffeine-sensitive. Its main trade-offs: premium price and tingles from beta-alanine remain If those don't apply to you, it's a solid choice in the stim-free pre-workout category.
Where is the best place to buy Legion products?

Can teenagers use Legion Pulse Stim-Free?
No — we do not recommend pre-workout supplements for anyone under 18. Caffeinated products are formulated for adults; pediatric guidance suggests limiting adolescent caffeine to roughly 100mg per day, which most pre-workouts exceed in a single scoop. Teens should build training energy through food, hydration, and sleep, and involve a parent and doctor in any supplement question.
