  • Boosted athletic, nootropic, and thermogenic performance

So, that covers exactly what you can expect when you consume this supplement on a regular basis. But, if you’d like to find out more about the ingredients, the next section will delve deeper into them.

Performance Lab Stim Review: Ingredients

The following section will take a closer look at the ingredients that are included within Performance Lab Stim. As we touched upon in the last section, this particular supplement combines caffeine with essential amino acids and vitamins, all of which you can see in the supplement facts label below:


NutriGenesis® Caffeine Balance B-Complex

When you consume caffeine, B-vitamins including B2, B6, B9, and B12 within the body begin to decline (1). This occurs due to the diuretic effect caused by caffeine which leads to loss of minerals and vitamins through frequent urination.

Thankfully, Performance Lab has included each of the aforementioned B-vitamins so that they can continue to perform essential functions within the body. This includes nervous system support, optimized energy metabolism, and the facilitation of neurochemical syntheses.

Natural Caffeine

It’s safe to say that Caffeine has long been a popular stimulant around the world. Most commonly associated with coffee, it’s an effective, natural source of energy that you can rely on. A dosage of 50mg per capsule allows you to enjoy a cuppa while avoiding the cognitive impairment caused by overconsumption. Thanks to the small dosage of caffeine per capsule, you have the freedom to consume up to a further four capsules daily if required.

Ajipure® L-Tyrosine

L-Tyrosine is an amino acid that allows you to sustain focus when performing stressful tasks or performing intense workouts.  It is highly recommended that you supplement with it if you consume caffeine on a regular basis. This is because it helps you to avoid a brain crash and reduces the likelihood of you ‘hitting a wall’ during high-stress situations. For that reason, it’s a great inclusion from Performance Lab.

Suntheanine® L-Theanine

L-Theanine is an amino acid that goes hand in hand with caffeine. This is because caffeine takes care of energy and focus, while L-Theanine helps to take the edge off things by allowing you to avoid jitters. Therefore, it’s clear that it’s an ingredient to look out for when you are searching for a caffeine supplement.

Side effects of Performance Lab Stim

As with all stimulant-based supplements, there are certain limits involved that you’ll need to conform to. Otherwise, you could end up having the opposite effect to what you want. In turn, this could actually result in you feeling more sluggish than you were before.

For that reason, it’s important to test your tolerance to caffeine with a little trial and error. So, to begin with, we recommend that you stick to one capsule and gradually increase the dosage if necessary. This will enable you to avoid unwanted side effects such as energy crashes and jitters.

How to take Performance Lab Stim

The serving size of Performance Lab Stim is just one capsule, which makes it perfect for those who are constantly on the go or follow a hectic schedule throughout the week. This equates to a dose of 50mg of caffeine per serving – providing you with a quick energy boost when you need it the most.

However, if you feel that this isn’t adequate enough, or your caffeine tolerance is higher, it’s possible to take up to 5 capsules each day. It’s always worth sticking to the minimum recommended serving size to begin with. This means that you can increase your dosage if you deem it to be necessary. Just don’t exceed 5 capsules each day (250mg of caffeine), as this may be counterproductive.

Another thing worth bearing in mind is that you should limit your caffeine intake in other areas of your diet. Yes, that means that you’ll potentially need to cut down on the amount of coffee you consume each day, I’m afraid. If you do just that, you stand a better chance of avoiding negative side effects such as those previously mentioned.

Performance Lab Stim – Personal Experience

After taking Performance Lab Stim for a few weeks, it was possible to find the optimal dosage and still enjoy a cup of coffee or two. This is why we recommend that you do the same so that you can find what works for you the best.

Overall, I found that it effectively increased my levels of alertness and reduced fatigue when I consumed a capsule in the morning with a cup of coffee. This allowed me to effectively focus on intensive tasks and power on through tough workouts in the gym. An added bonus was that I was able to avoid the mid-afternoon slump affecting office workers across the globe!

On certain days, I’d feel the need to take another capsule. However, this was only when I felt as though I’d had my coffee fix for the day!
