Description

PER4M 2.0 is the supercharged, limited-release big brother to the original PER4M. Nexus rebuilt it as an all-out high-stimulant pre-workout, doubling the serving size to 32g and packing it with maximum-effort doses for the lifter who wants the strongest possible hit of energy, pumps and strength.

This is a serious formula for serious training. Expect relentless energy, deep nootropic focus and big pumps, with added creatine and recovery actives so you're not just amped, you're performing. Each new flavour drops in a strictly limited allocation, so when it's gone, it's gone.

Key Benefits

  • 10g L-citrulline for nitric oxide and pumps
  • 500mg caffeine, over twice the original, for maximum energy
  • 3g creatine monohydrate for strength and power in the same scoop
  • 5g beta alanine for endurance support
  • 50mg Senactiv plus a deep nootropic blend for focus

Nexus PER4M 2.0 in Dark Matter 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 Dark Matter 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 Dark Matter 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.

Nutrition per serving. Key ingredients: Caffeine Anhydrous, L-Citrulline, Beta-Alanine, Creatine Monohydrate, Alpha GPC, Senactiv. Flavour: Dark Matter.

Mix with water and drink it 20 to 30 minutes before training. Begin with a half serve to assess tolerance given the high stimulant content. Do not exceed one serve in 24 hours, and avoid use within 6 hours of sleep.

PER4M 2.0 is for stimulant-tolerant, experienced lifters chasing the strongest pre-workout Nexus makes. It is not for beginners or anyone caffeine-sensitive. Always assess tolerance with a partial serve first and never combine it with other stimulants. It mixes clean even at this fully loaded dose.

How is 2.0 different from the original PER4M?

It's roughly double the serving size with about 500mg caffeine, 10g citrulline, added creatine and a deeper nootropic blend, making it significantly stronger.

Is it a limited release?

Yes. PER4M 2.0 flavours drop in strictly limited batches and don't return once sold out.

Should beginners use it?

No. This is a maximum-strength formula best left to experienced, stimulant-tolerant users.

Does it contain creatine?

Yes, around 3g of creatine monohydrate per serve to support strength and power.

Can I stack Nexus PER4M 2.0 Juicy Burst with a separate creatine product?

Yes. Nexus PER4M 2.0 already includes 1.5g Creatine Monohydrate per scoop (3g at the brand's 2-scoop dose), so if you run a dedicated creatine product too, add that dose on top and track your combined daily intake rather than doubling up blindly.

How long before training should Kiwi lifters take Nexus PER4M 2.0?

Around 20 to 30 minutes pre-session is standard, giving the 250mg caffeine anhydrous and 5g L-Citrulline time to kick in before you start your first working set. Consistent use on training days matters more than nailing an exact minute, since beta-alanine's benefit builds over time.

Is Nexus PER4M 2.0 Juicy Burst too strong for someone new to pre-workout?

At 250mg caffeine per scoop, a single-scoop serving sits at a moderate dose rather than the brand's full 2-scoop, 500mg serving. If you are new to stimulant pre-workouts, starting with 1 scoop of Nexus PER4M 2.0 rather than the full dose lets you judge your own tolerance first.

How should I store my Nexus PER4M 2.0 tub once delivered in New Zealand?

Keep the 800g Nexus PER4M 2.0 Juicy Burst tub sealed, upright and away from direct heat or damp, which is typical for NZ pantries and gym bags alike. A tight-sealed scoop stays fresher across all 50 servings than one left open between sessions.
