The first of its kind from the brand, Performance Lab Stim is the first formula from the company that uses a stimulant as its main ingredient. Asserting to help activate the brain using caffeine, but without its typical side effects, can Performance Lab validate this claim? Let’s find out.
What is Performance Lab Stim?
As a supplement brand, Performance Lab provides some of the highest-rated products in the nootropic market. So far, the company had avoided stimulants completely building their brand around purely non-stimulant products.
So, why the change of heart with a new stim product? Well, it seems that Performance Lab may have detected a gap in the nootropic market with the need for safe but effective and balanced stimulation.
But instead of putting together a multitude of stimulants, the company spent time devising a product that offers clean stimulation sans the jitters.
The thing to remember here is that Performance Lab Stim is not intended to be an athletic enhancer. Sure, caffeine can potentially help with energy, endurance, and exercise intensity, but the very moderate dosage include in the formula caters more to cognitive enhancement.
The brand has other, far more effective pre-workout supplements for that purpose. If you experience some degree of athletic boost, it’s a welcome bonus but not the design of the product.
Performance Lab Stim Review
On the surface, Performance Lab Stim seems like any other stimulant that helps users keep going when they want to work harder but also don’t want to drink coffee. But when you look deeper, it’s actually a brain supplement that doesn’t rely as much on caffeine as it does on the combination of expertly selected ingredients to give your brain the right boost.
With this formula, caffeine only acts as an instigator to get things going. The rest of the benefits come from what the other ingredients do synergistically. But to understand that a little better, you’ll have to take a closer look at what makes up the rest of this formula.
Performance Lab Stim Ingredients
Stim uses a clever combination of seven ingredients to give you what the manufacturers call the ultimate “clean energy experience.” This implies that yes, caffeine would do its part in all of this, but not in the way other stimulant-based products do.
Instead, Stim’s subtle stimulant boost paired with other ingredients for recovery and balance will primarily target users at helping them multitask, handle stress, boost alertness, enhance memory, improve mood, and whatever they may need more help with.
Natural Caffeine (From Coffea Robusta Seeds)
When manufacturers say natural coffee, they mean it isn’t caffeine anhydrous, which is the most common caffeine variety added to every sports supplement available.
This form of caffeine is inexpensive and readily mass-produced, whereas naturally sourced caffeine is harder to extract and adds to its production cost.
In its purest form, coffea robusta is coffee that hasn’t been roasted yet and is the form of caffeine Performance Lab Stim uses in its formula for maximum potency.
With only 50 mg, Stim gives you about the same jolt as a shot of espresso. You get a stimulating, targeted dose but without going overboard. As such, you avoid the jittery side effects of coffee.
If any substance is the perfect anti-caffeine, it’s L-theanine. That’s why it’s a popular addition to numerous gym supplements where it helps counter the potential side effects of heavily dosed stimulants with caffeine ranking the most prominent.
Yet, its role in Performance Lab Stim is more of a nootropic nature. In this capacity, L-theanine is accepted to boost wakeful relaxation, improve creativity, and lower anxiety while working on improving mood. 
And given the fact that it doesn’t have a sedative nature, there is no concern about feeling sleepy while at work or when studying when you supplement with L-theanine.
Tyrosine counts as another nootropic that is added for relieving stress and improving focus benefits.  Manufacturers claim that tyrosine helps reduce neurotransmitter changes that caffeine induces. Adding in L-tyrosine to the formula is the recovery aspect of Performance Lab Stim as it’s the perfect ingredient to lower stress levels during stressful episodes or improve alertness after inadequate sleep.
Tyrosine assists in synthesizing and recycling catecholamine. This reduces the possibility of attention issues, mood fluctuations, and energy crashes.
NutriGensis® Caffeine Balance B-Complex (B Vitamins)
As you can see, every ingredient in the Stim formula has been selected carefully to carry out a very precise role, so what about the B vitamins?
These vitamins in question here are B2, 6, 9, and 12. Incidentally, these four vitamins tend to drop in levels with caffeine consumption, and restocking them is essential.
These vitamins counterbalance the effects of caffeine, helping the body handle stress, optimize energy, and support optimal homocysteine levels.
Speaking of which, caffeine raises homocysteine, which can trigger brain fog, forgetfulness, and related memory issues. The B vitamins make up the balancing segment of Performance Lab Stim.
Does Performance Lab Stim Work?
While the individual ingredients in Performance Lab Stim work well, it is their combined effect that makes this formula so potent.
Starting with the caffeine-theanine combination, which has been proved more effective than using caffeine on its own via clinical trials. 
This dynamic duo is successful in resisting distractions, sustaining focus, and switching attention to the next task when needed.
Plus, theanine adds in a creative element. Instead of just promoting alertness and reducing fatigue, the two work synergistically together. When combined, you get all the benefits of caffeine, with none of the drawbacks giving you a clean energy experience.
And the fact that both are taken from completely natural sources only improves their potency.
Here’s a real quick breakdown of how all of Stim’s ingredients balance each other out:
- While caffeine increases demand on neurotransmitters, the other ingredients all support neurotransmitters.
- Caffeine decreases Alpha brain waves, but L-theanine raises and sustains them.
- Caffeine initiates a fight-or-flight response causing adrenal glands to release more cortisol. L-theanine regulates cortisol production, L-tyrosine optimizes performance under stress, and B vitamins help meet the increased demands of stressed adrenals.
- Caffeine constricts blood vessels while L-theanine counters that.
- Caffeine has a diuretic effect causing the excretion of B vitamins, but the highly absorbable NitriGenesis®B-Complex restores what caffeine depletes.
- Caffeine raises homocysteine levels while B vitamins maintain healthy homocysteine metabolism.
Another consideration here is that when you correlate only 50mg of caffeine to what’s found in workout supplements, it really makes the Stim formula seem weak. However, Stim isn’t a workout supplement as much as it is a brain and focus supplement.
So, depending on individual tolerance, 50mg may be good enough, or too mild to be of any effect. For most, it is strong enough for a gentle hit, but low enough to double or even triple the dose if you prefer.
Performance Lab Stim Side Effects
Given its non-GMO, allergen-free, and vegan-friendly plant caps, Performance Lab Stim doesn’t come with any side effects.
The sensible 50mg dosage of natural caffeine paired with 100mg theanine gives users the right burst of energy without the risk of jitters or causing any energy crashes.
While usual precautions would otherwise apply to caffeine, this formula doesn’t do that. At 50mg per serving, caffeine is restrained and leashed, and adding in theanine to an insignificant caffeine presence makes any stimulant-based side effects almost irrelevant.
Performance Lab Stim seems safe and effective for anyone craving healthy stimulation. Anyone looking for a safe and effective stimulant that won’t cause jitters can use this. As such, it can be used in all kinds of settings.
While it could certainly improve sports performance, it’s equally ideal for career-minded people, students, and health-conscious individuals. Anyone who responds unfavorably to caffeine and other energy drinks will especially enjoy Stim.
Overall, caffeine is the singular ingredient susceptible to bring about side effects but only at higher doses. However, the L-theanine and L-tyrosine in the formula can alleviate most issues.
Performance Lab Stim Reviews
The Performance Lab Stim formula is clean cut with a premium feel. Users like that it is not reliant on caffeine and boasts brain benefits, which are more than just alertness and stimulation.
The serving size, as suggested by the manufacturer, is to take one cap for stimulation.
Stim’s 50 mg caffeine dose is adequate for most. But people with greater tolerance may up their dosage in 50mg increments up to 200mg caffeine or four capsules per day.
This is perhaps where a lot of the appeal of Performance Lab Stim lies. Most people can toy around with the way Stim works for them and enjoy the flexibility of making up their own dosage.
That said, while you have the flexibility to experiment with your optimal dosage, you should also monitor your caffeine intake in other areas of your diet.
Basically, this implies that you should cut down on the amount of caffeine you consume elsewhere during the day.
