    Alpha neon darkside onslaught

    Posted by Andrew Turton on 27th Aug 2022

    This pre workout is absolutely unreal so strong and I can say myself I am a bit of a stim junkie but even half a scoop blew my head off. Only ever use it on really heavy load days if you are thinking of ordering go for it you won’t regret it

    Darkside Onslaught

    Posted by Mitchell Austen on 6th Mar 2021

    Well where do I start, I've only ever used energy drinks as a go to for my workouts which are good but don't last long so I thought I'd give it a shot and bought darkside onslaught and my god what a difference, I feel the buzz the same as the energy drinks from the caffeine but the one thing that stands out is the sheer endurance it gives me, before I was getting half way through my workouts and flagging but now I can go on for hours and still pushing as hard and it makes the last set feel like the first! Absolutely excellent stuff, highly recommended would love to see some more flavours, probably won't use any other preworkout, if your on the fence about trying it just buy it you won't be disappointed!
