I've always had a high caffeine pre-workout. I honestly didn't realise I could train this well without it. Took INFRNO around 20 minutes before my workout and had one of my best sessions. Looking forward to using it again tomorrow. Tastes great too.

Mega stuff. Ordering again. Brilliant energy, great pumps and I can still sleep properly afterwards. Exactly what I wanted from a non-stim pre-workout.

I'm former military and train almost every day. This is easily the best pre-workout I've used. No jitters, no crashes and I still sleep perfectly at night. This is now a permanent part of my routine.

Easy to use, tastes great and gives a steady boost throughout the workout without the sudden energy drop I normally get from stimulant products.
