Who it’s for
PER4M is tailored toward a specific type of gym-goer, and here’s how to know if it suits you.
This pre-workout is ideal for intermediate to advanced athletes who already have experience with high stimulant pre-workout supplements. Its balance of energy, pump, and focus agents makes it a good fit for those who want a single product that covers all bases without heavy stacking. However, if you are sensitive to caffeine or prefer a low-stim product, starting with a half scoop is strongly recommended.
Stacking suggestions
Knowing what to stack PER4M Pre-Workout with can help round out your supplement routine.
- Post-workout: A high-quality whey protein or whey protein blend to aid muscle recovery.
- During training: Electrolytes to offset fluid loss from the caffeine and keep hydration levels steady.
- Daily support: Creatine for muscle strength and growth, as it isn’t included in the formula.
Frequently asked questions
Here are some quick answers to common queries about PER4M Pre-Workout:
How much caffeine does it contain?
Each serving provides 200mg of caffeine anhydrous, equivalent to about two cups of coffee.
Can I take PER4M Pre-Workout every day?
Yes, but it’s best cycled or alternated with non-stim days to avoid building tolerance.
Does it cause tingling?
Yes, the Beta-Alanine may cause a temporary skin-tingling sensation, which is normal and harmless.
When should I take PER4M?
Take one scoop mixed with water 20–30 minutes before training for best results.
Suggested use
A little guidance ensures you get the most from this formula.
Mix 1 scoop (9g) with 300–400 ml of cold water and consume 20–30 minutes before your workout. Beginners or those sensitive to caffeine should start with half a scoop to assess tolerance. Avoid taking too late in the day to minimise sleep disruption.
