- ★★★★★Chris B.09/12/2025Science-backed formula
Pharmacist checked the ingredients. L-citrulline at 6g (proper dose), beta-alanine at 3.2g (clinical dose), tyrosine at 2g (evidence-based for focus). None of the underdosed proprietary blend rubbish. Actually works.
- ★★★★☆Rachel K.Verified buyer18/11/2025Good for cardio
Using this before long cycling sessions rather than gym. The vasodilation from citrulline improves endurance performance. No crash afterwards. Tastes good mixed in 400ml water.
- ★★★★★Mike C.Verified buyer05/09/2025Same pump, none of the crash
Trained with stimulant pre-workouts for years then started getting anxiety and sleep disruption. Switched to this. The pump from citrulline is real, focus is there, and I sleep fine after evening sessions.
- ★★★★★Hannah W.Verified buyer16/08/2025Finally a pre-workout without jitters
Anxiety and caffeine sensitivity mean stimulant pre-workouts are out. This stimulant-free version has citrulline for blood flow, beta-alanine for endurance, and tyrosine for focus. Actual performance improvement without racing heart.
