Nexus PER4M 2.0 - Sour Apple, 800g (50 Serves)

Nexus PER4M 2.0 in Sour Apple is a fully dosed pre-workout from Nexus built for lifters who want measurable output, not a mystery blend. Each 800g tub runs 50 single-scoop servings, with 5g L-Citrulline, 2.5g Beta-Alanine and 250mg caffeine anhydrous in every scoop. If you train early, lift heavy or just want a pre-workout you can actually see the numbers on, Nexus PER4M 2.0 gives you a label with nothing hidden.

How Nexus Pre-Workout works

The 250mg caffeine anhydrous in Nexus PER4M 2.0 works by blocking adenosine receptors in the brain, the mechanism behind feeling less fatigued and more alert during a session. L-Citrulline is a precursor to L-arginine, which the body converts into nitric oxide, supporting blood flow to working muscle. That is the physiology behind the pump lifters chase from a citrulline-based pre-workout.

Beta-Alanine works differently. It raises muscle carnosine levels over time, and carnosine helps buffer the hydrogen ions that build up during high-rep training, which is why steady beta-alanine use is linked to holding output later into a set. Creatine monohydrate, dosed at 1.5g per scoop in Nexus PER4M 2.0, supports the phosphocreatine system that fuels short, high-intensity efforts, on top of whatever creatine you already stack in from a separate creatine product.

Why choose Nexus PER4M 2.0

Beyond the headline actives, Nexus PER4M 2.0 Sour Apple is built as a genuinely fully dosed formula rather than a caffeine-and-flavour shell. A few things set the label apart from a typical stim pre-workout:

• 250mg Agmatine per scoop, alongside the citrulline, for lifters chasing a stronger pump on pre-workout day.
• 500mg L-Tyrosine plus 125mg Alpha GPC and 100mg L-Theanine per scoop, a focus-leaning stack layered under the caffeine rather than caffeine standing alone.
• 400mg Taurine per scoop, a dose worth knowing if you already track your intake from other amino acid products.

Every one of those numbers is printed on the Nexus PER4M 2.0 label at the 1-scoop serving, and the brand's recommended full dose is 2 scoops, doubling each figure above.

Getting the most from it

Most lifters take Nexus PER4M 2.0 Sour Apple around 20 to 30 minutes before training, giving the caffeine time to take effect and the citrulline a head start on blood flow. Because beta-alanine works cumulatively through muscle carnosine, the benefit builds with consistent scoops rather than a single big dose, so using it on your regular training days matters more than the exact minute you drink it.

Training in NZ heat or running a long session pushes fluid needs up, so pairing Nexus PER4M 2.0 with something from electrolytes is worth considering on top of your usual water intake. If your goal is size or recovery rather than pure output, a scoop of Nexus PER4M 2.0 stacks cleanly alongside a post-session shake from protein, with the creatine dose here contributing toward your daily total.
