Nexus PER4M 2.0 — The High-Stim Evolution of PER4M
Nexus PER4M 2.0 is the upgraded formula built for serious lifters who train hard and want their pre workout to match — 21 clinical-grade ingredients in a massive 32g full serve, headlined by 500mg of caffeine, substantial L-Citrulline for pumps and Beta-Alanine for endurance. One of the most comprehensive high-stim pre workout formulas available in NZ. 50 serves, in stock at TopDog Nutrition.
Key Features
- 500mg caffeine per serve — among the highest in the market. Experienced high-stim users only. Start at half a serve to assess tolerance.
- 21 clinical-grade ingredients — a fully loaded formula covering energy, pumps, endurance, focus and performance support.
- Massive L-Citrulline dose — nitric oxide and blood flow support for serious training pumps.
- Beta-Alanine — acid buffering for extended endurance through demanding sets.
- 32g full serve — the large serving size reflects the clinical doses, not filler.
PER4M 2.0 or Original PER4M?
PER4M 2.0 is the higher-potency evolution — 500mg caffeine, 21 ingredients, 32g serve. The original PER4M is the 17-ingredient, 16g serve formula — still a premium product but more accessible for users building their tolerance. If you're new to Nexus, start with the original. Browse the full pre workout range.
Directions
Mix one full serve (32g) or half serve (16g) with 300–400ml of cold water 20–30 minutes before training. Start with half a serve — 500mg caffeine is very high. Avoid within 6 hours of sleep. Do not combine with other caffeinated products. Experienced users only.
Frequently Asked Questions
How strong is 500mg caffeine?
Five coffees' worth in a single serve. This is at the absolute top of the pre workout market and not suitable for beginners, caffeine-sensitive individuals, or anyone without an established high-stim tolerance. Half a serve (250mg) is the appropriate starting point for anyone trying PER4M 2.0 for the first time.
