PER4M is the flagship hard-hitting pre-workout from Nexus Sports Nutrition, built for lifters who want a fully loaded scoop. It pairs a heavy stimulant kick with proven pump and endurance actives, so you get sharp energy, strong focus and big pumps from the first set.
The flexible dosing sets PER4M apart. Run a single 8g scoop on a lighter day, or push the full 16g hardcore serve when you need everything the formula has to give. Either way you tap into long-lasting energy, better blood flow and the kind of locked-in focus that turns an average session into a personal best.
Nexus PER4M Blue Sour Straps is an 400g high stimulant pre-workout from Nexus, built for lifters who train hard and want a single scoop to cover energy, pumps and focus at once. Each 8g serve carries 200mg of caffeine alongside 3000mg of L-citrulline malate, and the 400g tub runs to 50 single scoops or 25 full 16g hardcore serves. It is aimed at anyone training sessions that demand more than a coffee can deliver.
The caffeine anhydrous in Nexus PER4M Blue Sour Straps is what most people notice first: it blocks adenosine receptors in the brain, which is the mechanism behind feeling more alert and less fatigued once a session gets underway. Layered under that is L-citrulline malate, the amino acid your body converts to L-arginine and then nitric oxide, which relaxes and widens blood vessels so more blood, oxygen and nutrients reach working muscle during a set.
Beta alanine plays a different role. It raises muscle carnosine levels over time, and carnosine buffers the acid that builds up in muscle tissue as reps add up, which is why lifters use it to push volume later into a session. Alpha GPC contributes choline, a precursor the brain uses to produce acetylcholine, the neurotransmitter tied to mind muscle connection and sustained concentration mid-set.
Nexus PER4M Blue Sour Straps is dosed to be used, not just labelled. A few reasons it holds up against a lighter pre-workout:
The scoop-to-scoop consistency across all 50 serves in the tub means the same dose every session, not a guess.
Mix one 8g scoop of Nexus PER4M Blue Sour Straps with water around 20 to 30 minutes before you start lifting, giving the caffeine and citrulline time to take effect before your first working set. First-time users are better starting with a single 8g scoop before stepping up to the 16g hardcore serve, given how much caffeine that full dose carries. On heavier training blocks, some lifters pair it with a creatine from /collections/creatine for the strength side of the equation, or keep electrolytes from /collections/electrolytes on hand for longer sessions in the heat. If you are building a full stack, the wider /collections/pre-workout range covers other Nexus PER4M flavours alongside complementary aminos at /collections/amino-bcaa, so you can rotate flavours without changing what is actually in the scoop.
Mix 1 scoop (8g) with around 625ml of water for a standard serve, or 2 scoops (16g) for a hardcore serve. Drink it 20 to 30 minutes before training. Do not exceed the recommended serving, and avoid use within 6 hours of sleep due to the caffeine content.
PER4M suits experienced trainers who like a strong, stimulant-driven pre-workout and want pumps, endurance and focus in one tub. If you're caffeine-sensitive or new to pre-workouts, start with a single scoop to assess tolerance before stepping up. It mixes clean, so every serve goes down easy.
It's a high-stimulant pre-workout, delivering 200mg of caffeine per 8g scoop and up to 400mg in a full 16g hardcore serve. Assess your tolerance with a single scoop first.
Yes, though to keep the energy hitting hard, many lifters cycle off stimulant pre-workouts periodically or save the full dose for their toughest sessions.
The beta alanine can create a harmless tingling sensation on the skin. This is normal and fades as you train.
50 single scoops, or 25 full hardcore serves.
Yes. Nexus PER4M covers energy, pumps and focus, while creatine works on a separate, longer cycle for strength and power. Many Kiwi lifters keep a tub of each and scoop them together pre-training. Browse the range at /collections/creatine.
Yes, the 400g (50 serve) tub of Nexus PER4M Blue Sour Straps ships to addresses throughout New Zealand. Add it from the Pre-Workout collection at /collections/pre-workout and it goes out with the rest of your NZ Supps order.
That is down to your own post-training nutrition and not something this pre-workout dictates. If you already run a whey or plant protein, nothing in Nexus PER4M changes that routine, and you can browse options at /collections/protein.
Keep the tub sealed, upright, and out of direct sun or a hot car, which matters through a New Zealand summer. A cool, dry cupboard preserves the powder's texture and potency between scoops far better than a gym bag left in the heat.
