If I’m training in the morning (which isn’t very often) this gives me license to add in a stimulant based pre-workout, safe in the knowledge that the stimulants will have cleared my system by the time I retire to bed later on that night.

Although the ingredient list is pretty hefty, I never feel like the stimulants overpower me, I always feel like I am able to keep focus and clarity on my training at all times, which for me is important.

On the rare occasion I do use this, I like to stack it with VascuMax Pro, so I’ve got all of the angles covered… raw energy, razor-like focus and insane pumps!

Who it’s for:

If you’re chasing unfiltered energy, razor-sharp focus, and a serious pump for big lifts, heavy conditioning, or long sessions, this is your go-to. Perfect for gym beasts, athletes, or gamers who want to be ‘dialled in’.

What it does:

With 6 g citrulline giving you that vascular pump, 3.2g beta-alanine for endurance, 250mg caffeine for pep, and brain-power additions – EnXtra® & juniper – this formula brings clarity and volume. Think of it like upgrading from standard petrol to racing fuel – it fires you up, keeps you driven, and lets you stay sharp to the finish line.

How I would use it:

I’d mix one 12g scoop with 250 ml(ish) of water about 20 minutes before training. Beginners should test the waters – half scoop first to assess tolerance – then go full scoop when ready. It’s your performance cheat code – just don’t use it at from 4.00pm onwards if you value the quality of your sleep.

The Science:

Multi-formula Pre-Workout enhances anaerobic power and reduces perceived exertion

Study: Acute effects of a multi‑ingredient pre‑workout dietary supplement.

This randomised, crossover trial in untrained men assessed a MIPS including beta-alanine, taurine, caffeine, L‑tyrosine, and cayenne. It demonstrated significant improvements in Wingate test peak power (p = 0.009) and mean power (p = 0.04) compared to placebo – spotlighting real ergogenic benefits from components similar to citrulline and tyrosine used in StimuMax Pro.

L‑Tyrosine helps maintain cognitive performance under stress and fatigue

This comprehensive evidence review shows that L‑tyrosine supplementation can support working memory, executive function, and decision-making during acute stressors such as prolonged exercise, sleep deprivation, or cold exposure. It acts by replenishing catecholamine neurotransmitters (dopamine, norepinephrine).
