Collection: Pre-Workout

A good pre-workout should do three things well: help you feel switched on, help you train harder, and help you stay consistent. Whether that means a bigger hit of energy, a smoother daily-driver boost, or a stim-free pump you can take any time of day, the goal is the same: turn up to sessions ready to perform.

Per4m’s range is built around different training styles and caffeine tolerances, with multiple flavour options across each formula, so you can match the product to the way you train.

Which type should you choose?

1) Stim-based pre-workout for hard sessions

If you train heavy or you want a more aggressive “locked in” feel, a stim-based pre-workout is usually the pick. Pre-Workout Stim is designed for energy, focus, and pump support, and it’s available in a wide range of flavours.

2) A daily-driver option for consistent training

If you want a smoother boost you can use year-round without feeling overstimulated, Energy Pre-Workout is built for steady energy and focus, and it’s available in multiple flavours.

3) Stim-free pump for late training or stacking

If you train in the evening, you’re caffeine-sensitive, or you want pump support without stimulants, Pump Stim Free Pre-Workout with Glycersize™ is the clean option. It’s zero caffeine, built for pump and training feel, and it includes Glycersize™ as a separate add-in to avoid clumping.

4) Ready-to-go shots for zero prep

If you want maximum convenience, Energy Pre-Workout Shots are made for grab-and-go training days. Keep one in your bag for the sessions where mixing powder just isn’t happening.

When to take pre-workout

Most people take pre-workout 15 to 30 minutes before training. If you’re using a caffeinated option, be honest about your sleep. Late caffeine is one of the easiest ways to ruin recovery, so if you train late, go stim-free or keep caffeine lower.

How to use it properly

Start with less than a full serving. Your first few sessions should be about tolerance, not ego. If you feel great on half, there’s no reason to force more.

Hydration matters. Pre-workout tends to work better when you’re already hydrated. If you sweat heavily or cramp easily, pairing your routine with an electrolyte product can help. Browse options here: Hydration.

Keep your stack simple. If you already use creatine, keep taking it daily. Timing isn’t the main factor, consistency is. Options are here: Creatine.

Pre-workout benefits

Energy and focus you can feel

Caffeine is one of the most researched performance ingredients. If you’re sensitive, keep the dose sensible and avoid taking it too late in the day.

Training intent and output

The real value of pre-workout is what it enables: better sessions, more consistent effort, and stronger progression over time when the rest of your plan is solid.

Pump and training feel

If you care about pump, look for formulas that prioritise pump-focused ingredients. If you care about sleep, stim-free options keep late sessions on track.

FAQs

Should beginners use pre-workout?

You can, but you don’t need it. If you do use it, start with a smaller serving and choose a formula that matches your caffeine tolerance.

Why do I get tingles from pre-workout?

That tingling feeling is often from beta-alanine. It’s common and usually reduced by using a smaller serving.

Can I take pre-workout every day?

If you tolerate it well, yes. The main watch-outs are caffeine dependence and sleep disruption. If either slips, scale back.

Important: Check the label guidance. If you’re caffeine-sensitive, pregnant, breastfeeding, under 18, or have a medical condition, speak to a healthcare professional before use. Don’t exceed the recommended serving.
