Nexus PER4M 2.0 – Maximum-Potency Pre-Workout for Advanced Trainers

PER4M 2.0 is engineered for experienced lifters demanding the highest-stim formula on the market. With 500mg caffeine, 21 clinical-grade ingredients, and a substantial 32g serving, this is a complete performance stack covering energy, blood flow, endurance, and mental focus. 50 serves per container.

What's Inside

• 500mg caffeine – extreme potency for advanced users only. Equals roughly five espressos per full serve.
• 21 research-backed ingredients – no filler, just clinical doses across all performance pillars.
• Premium L-Citrulline – maximises nitric oxide production for aggressive muscle pumps.
• Beta-Alanine – buffers lactic acid to extend performance through high-rep work.
• 32g full serving – large dose size reflects potency, not padding.

How to Use

Mix 32g with 300–400ml cold water 20–30 minutes pre-workout. New users must start at half serve (16g, 250mg caffeine) to assess tolerance. Avoid caffeine within 6 hours of sleep. Do not stack with other stimulants. For experienced high-stim users only.

PER4M 2.0 vs Original PER4M

PER4M 2.0 is the maximum-strength tier – double the caffeine and five extra ingredients versus the original 17-ingredient formula. Choose the original if building stim tolerance or prefer a gentler approach. Both are premium-grade.

Is 500mg Caffeine Right for You?

This extreme dose suits only experienced users with proven tolerance to high-stim products. Beginners, caffeine-sensitive individuals, and those without established tolerance should start elsewhere. Half a serve is the minimum entry point for first-time users.
