About Performance Lab Stim
As a supplement brand, Performance Lab provides some of the best quality products on the market.
They offer completely vegan supplements without any additives or synthetics. Furthermore, each batch they release is third-party tested by the likes of the UL, so you know exactly what’s in it.

In a nutshell, Performance Lab Stim provides clean, effective performance enhancement through optimal dosing of caffeine.
Combined with an elite brand of l-theanine, Performance Lab claims this supplement will stimulate you while avoiding common side effects.
One thing that interested us in particular is this: Performance Lab Stim contains the B-Vitamins that caffeine is known to deplete (in their exact dosages that caffeine depletes B-Vitamins in). So it’s clear that no expense has been spared by their R&D team.
In this review, we’ll look at all individual ingredients found in this advanced stimulant and dosages. To find out how they stack up against other stimulants.
Take a look:
Performance Lab Stim Supplement Facts
Performance Lab Stim contains the following ingredients:
- 500 mcg Riboflavin
- 750 mcg Vitamin B6
- 167 mcg DFE Folate
- 50 mg Natural Caffeine (Coffea robusta)
- 100 mg Suntheanine L-Theanine
- 250 mg Ajipure L-Tyrosine
*To learn more about Performance Lab Stim’s Ingredients
The human body needs enough riboflavin to maintain overall health. Also known as vitamin B2, it helps our cells produce energy from fats.
As a cofactor in fatty acid metabolism, it carries electrons through the transport chain to yield ATP. It even helps mobilize iron and increase its bioavailability.
We need iron to carry oxygen to our brains and working muscles. Therefore, riboflavin indirectly feeds your workout, giving you more energy to perform.
In Performance Lab Stim, riboflavin works with the other B vitamins to create a powerful complex. Specifically, it’s flavin coenzymes help convert other B vitamins so your body can use them.
Vitamin B6, also called pyridoxine, plays a part in the health and generation of red blood cells. As such, it contributes to oxygen transport in your bloodstream. When starved of oxygen, your brain and muscles start to fatigue. Regular vitamin B6 intake is therefore crucial to optimal functions
It’s also a coenzyme for energy metabolism, helping breakdown glycogen to form ATP. Furthermore, vitamin B6 assists in the breakdown and formation of amino acids.
Finally, vitamin B6 helps create the neurotransmitters GABA, serotonin, norepinephrine, and dopamine.
Research shows that even a slight deficiency of B6 impairs the synthesis of these neurotransmitters. Symptoms include disrupted sleep, mood, and behavioral issues, and decreased hypothalamic-pituitary control.
Another B vitamin in the energy complex, folate keeps your nervous system running smoothly. Together with vitamin b12, it repairs neurons and keeps cell membranes intact. As kids, folate contributes to normal brain development.
In adults, adequate folate intake contributes to healthy hippocampus function. Your hippocampus regulates emotion, learning, and memory, so taking folate can help clear up cognition.
On top of the other B vitamins in the mix, folate helps you think better in tough situations.
Caffeine (Coffea robusta)
Better known as green coffee, Coffea robusta simply means coffee that hasn’t been roasted yet. Performance Lab assumingly uses this particular type for its potency. As a small of caffeine gets lost in the roasting process, pulling from the green fruit skips that issue.
With only 50 mg, Stim gives you about the same jolt as a shot of espresso.
You get a stimulating, targeted dose without going overboard. So you avoid jittery side effects.
Research shows that caffeine, as a nervous system stimulant, can elevate performance.
But how does it work?
Your brain naturally produces a chemical called adenosine, which is a critical component of energy. In times of low-energy, adenosine levels rise and attach to specifically-shaped receptors. This connection causes drowsiness and brain fog.
Caffeine just so happens to be the perfect shape to bind with these receptors as well. When caffeine enters your system, it takes up the parking spaces for adenosine. By removing the opportunity for a bind, caffeine clears adenosine from these receptors.
Not only does this negate fatigue, but it also speeds up neuronal signaling.
The endocrine system reads this elevated activity and responds with a hormonal release. The subsequent release of adrenaline, norepinephrine, serotonin, and dopamine starts the stimulating effects commonly associated with caffeine.
The good news is that you won’t feel any jittery side effects due to Performance Lab Stim containing a sensible 50mg dosage of natural caffeine.
L-Theanine is an analog of the amino acids glutamine and glutamate. Commonly found in green tea, it’s known for its calming effects.
In animal studies, for instance, theanine has been shown to quite literally send electrical impulses in the brain.
It elevates the activity of alpha brainwaves, a specific type associated with wakeful relaxation.
The result? An anxiety reduction and balanced mood comparable to being in a meditative state.
This flow state is known for boosting creativity, cognitive coordination, and an overall presence of mind.
Additionally, l-theanine supports the neurotransmitters serotonin, GABA, and dopamine. These three work together to inhibit excited brain activity.
In turn, they upgrade attention, mood, and focused motivation.
In animal studies, theanine defends against nervous system damage, which could prove critical given the potential negative side effects of caffeine. Outside of the brain, these neurotransmitters keep blood pressure at normal levels.
In the face of stimulants, this relaxes your heart rate, reducing tension and anxiety.
So, in a nutshell, l-theanine is the perfect partner to caffeine.
Performance Lab Stim contains 100mg of theanine. For reference, you’d have to drink around 10 cups of green tea to receive the same. Unless you’re thirsty, Stim seems more convenient.
L-tyrosine is a non-essential amino acid used primarily to generate catecholamines.
Produced in the adrenal gland, your body released these hormones in response to stress. They elevate your heart rate, increase your breathing pace, and send blood to your vital organs. Catecholamines stimulate the laser-focus required to react to life’s challenges.
The more stress we’re in, the more catecholamines we need.
That’s where tyrosine supplementation comes in, adding the necessary ingredient to make more hormones.
Plenty of studies confirm that tyrosine helps us think better during times of extreme stress.
Because stress depletes catecholamine levels, it’s thought that tyrosine provides the fuel to keep things going.
In a sense, taking tyrosine is like recharging your cognitive batteries.

Performance Lab Stim Formula Analysis
While the individual ingredients in Performance Lab Stim work well, it’s the combined effect that takes the cake. First of all, clinical trials prove the theanine-caffeine combination to provide healthier stimulation than caffeine on its own.
The ability to resist distractions, sustain focus, and switch attention to the next task when necessary increased tremendously with this duo.
Theanine also adds a creative element. Rather than just promote alertness and reduce fatigue, caffeine and theanine work in synergy together. To form a platform for innovation. Performance Lab Stim’s 2:1 ratio matches that tested in the lab for maximum benefits.
Furthermore, they take both elements from completely natural sources – green coffee and pure green tea leaves.
There’s no doubt that caffeine is a performance-enhancing stimulant. However, in order to do so, it calls upon the catecholamines epinephrine and norepinephrine.
Studies show that acute caffeine ingestion increases urinary levels of these two in a dose-dependent manner, meaning your body is using them up. The addition of tyrosine in Stim, therefore, can replenish these chemicals to prevent burnout.
However, according to research, the ideal supplementation for an acute stress response hovers around 100-150mg/kg of bodyweight. Stim doesn’t quite meet these levels.
Finally, the three B-vitamins provide a solid foundation to balance stress. As folate, B6, and riboflavin all take part in energy metabolism, they become increasingly important during intense activity.
Those who work hard day-in and day-out could, therefore, benefit from a supplemental B-complex. Although they won’t enhance performance immediately, B-vitamins could affect long-term success.
Who Takes It?
Performance Lab Stim is safe and effective for anyone craving healthy stimulation. As the company offers an entire Sport line, we know they target elite athletes and exercisers looking to augment their efforts in the gym.
It’s taken by a range of athletes such as leading Crossfit competitors (such as Emma McQuaid). But you don’t have to be an athlete; anyone who is looking for a safe & effective stimulant (that won’t cause jitters) can use this.
As a result, Performance Lab Stim can be used in all kinds of settings.
It certainly would improve sports performance, but it’s also ideal for career-minded individuals, students, and health-conscious workers. Those who respond unfavorably to caffeine and other energy drinks will especially enjoy Stim.

Any Side Effects?
Thanks to being non-GMO, allergen-free, and vegan-friendly plant caps, Performance Lab’s Stim doesn’t come with any real side effects.
The sensible 50mg dosage of natural caffeine paired with 100mg l-theanine means that you feel ‘energized’ without any risk of jitters or energy crashes.
After taking it for 3 months, we didn’t experience any side effects.
We didn’t take it daily, so we didn’t build a tolerance to it either. We suggest taking it on days where you need it, rather than making it a ‘daily’ addition to your supplement stack.
