Per4m Energy Pre-Workout 390g - Daily PWO

Per4m Energy Pre-Workout 390g is a classic pre-workout booster, a so-called "daily pwo." This means it's a product that helps your muscles work better by delivering pure energy without excessive stimulation. The dietary supplement is especially recommended for individuals who do not tolerate a very high dose of stimulants. If you are focused on improving your training capacity in a real, effective way, rather than maximizing stimulation, then this pre-workout is tailored to your goal.

Per4m Energy Pre-Workout offers:

Immediate energy and better focus

With 200 mg of caffeine per serving, the product supports concentration, alertness, and the ability to be more engaged in training. Research confirms that caffeine "improves both anaerobic and aerobic performance." For individuals engaged in strength and endurance training – this is a real chance for a stronger start, less backing off towards the end of sets, and better muscle engagement.

Support for strength and muscle pump

L-citrulline acts as a booster for the NO (nitric oxide) system, which can contribute to better blood flow, better muscle pump, and delayed fatigue. Although research is mixed – some confirm benefits, others show no significant effect – it's worth noting that this supplement makes sense for high-intensity training. The combination of caffeine + citrulline + theobromine can work synergistically – which means: better utilization of the moment you "get into the workout."

Stable energy without the effect of distraction

100 mg of theobromine (20% cocoa extract) is a less typical ingredient that can support stable energy release. Thanks to this, you avoid the "waving" energy effect and power drops after 10–15 minutes. Your training sessions can be more balanced, less "up-and-down."

Universal application – for every type of training

Regardless of whether you train for strength, bodybuilding, endurance, or participate in challenge formats like CrossFit or Hyrox – this product is designed as a "daily-driver pre-workout." A solid dose of active substances, good taste, and a convenient form make it easy to incorporate into your training routine. Order today and gain an advantage over your own workouts!

What is Per4m Energy Pre-Workout?

Per4m Energy Pre-Workout is the answer to the needs of the conscious athlete. This is not a formula created for you to be "climbing the walls" for 20 minutes. It is a "daily-driver" product – your daily, reliable partner, designed to deliver clean, stable, and long-lasting energy that allows you to give your best from the first to the last minute of your training session.

Per4m Energy focuses on three pillars of true performance: balanced power, unwavering endurance, and laser focus.

My experience with the Per4m Energy booster

Let's start with the most important thing – the feeling. This is what defines a good pre-workout and builds trust in the product. When using Per4m Energy, you will not experience a sudden, uncontrolled "burst" that is often associated with anxiety, shakiness, or stomach problems.

The experience with Per4m Energy can be described as a "clean entry."

About 15-30 minutes after drinking a serving, you will feel your senses sharpen. This is not nervous hyperactivity, but rather a better mental readiness for effort. When you start your warm-up, you will notice that your muscles are more "willing" to work. This is the start of L-citrulline malate's action, which begins to dilate blood vessels, preparing the highways for oxygen and nutrients.

During the main part of the workout, energy remains at a stable level. Similarly, after the training session is over, we do not experience a sudden energy crash. I personally use it as my supplementation base before every workout, so that my muscles receive the ingredients that improve their performance.

Active Ingredients of Per4m Energy Pre-Workout Booster

200mg Caffeine and 500mg L-Tyrosine - Focus and Motivation

This is the duo responsible for your head. In the world of training, the mind-muscle connection is fundamental.

  • Caffeine: 200 mg of anhydrous caffeine is the "sweet spot." This dose is strong enough to significantly stimulate the central nervous system, increase alertness, shorten reaction time, and reduce the perception of pain and effort. At the same time, it is a dose that, for most people, does not cause excessive agitation or distraction. You receive pure energy for action and a greater desire to undertake heavy exertion.
  • L-Tyrosine: L-Tyrosine is an amino acid that is a precursor to key neurotransmitters, including dopamine and norepinephrine. In the context of training, this means that when your body is under stress (and heavy training is stress), L-tyrosine helps maintain a high level of concentration, motivation, and cognitive ability. It is what allows you to "get into the zone" and focus solely on the next repetition, without being distracted by fatigue.

2.5g L-Citrulline Malate - Endurance and Pump

L-Citrulline Malate (in 2:1 form) is one of the most important ingredients when it comes to muscle performance. Your body converts L-citrulline to L-arginine, which is then used to produce nitric oxide (NO). Nitric oxide is a powerful signal for your blood vessels to relax and expand. Wider blood vessels mean better blood flow. This, in turn, leads to two key benefits:

  1. Spectacular muscle pump: Muscles become fuller and harder because more blood flows into them. This is not only a satisfying feeling but also a sign of optimal nourishment.
  2. Greater endurance: Better blood transport means more effective delivery of oxygen and nutrients (like glucose) to working muscles and faster removal of metabolic waste products (like lactic acid). As a result, you feel fatigue later and are able to perform more work.

Beta-Alanine 1.6g - Buffer against Muscle Fatigue

If you have ever felt the characteristic "tingling" (paresthesia) after a pre-workout, that is the work of beta-alanine. This is a completely harmless and desired effect, signaling that the ingredient has started to work. Beta-alanine combines with histidine in the muscles, forming carnosine. Carnosine is your internal acidity "buffer."

100mg Theobromine: Stable Energy and Smooth Landing

Theobromine, naturally found in cocoa, among other sources, is the "intelligent cousin" of caffeine. It works similarly to caffeine by blocking adenosine receptors (responsible for the feeling of sleepiness), but its effect is much milder and slower. In the Per4m Energy formula, theobromine works in perfect synergy with caffeine. Caffeine provides a quick "hit" of energy, and theobromine enters right after it, extending and smoothing the energy curve. This ingredient is largely responsible for the lack of a sudden energy "crash" after training.

Niacin and Bioperine® - Maximizing Active Ingredient Absorption

Even the best ingredients are useless if your body does not absorb them. Vitamin B3 (niacin) is crucial for energy metabolism. It helps convert carbohydrates into usable energy. Bioperine® is a patented black pepper extract (piperine) that is a clinically researched "bioavailability enhancer." It increases the absorption and effectiveness of the other ingredients in the formula.

African Mango and Grains of Paradise Extract

The formula is complemented by two interesting plant extracts. African Mango extract (Irvingia Gabonensis) and Grains of Paradise are known for their potential to support metabolism and thermogenesis, which further aids the body's energy processes during exercise.
