Performix SST claims a spot with its unique formula. But does it truly stand apart in its promise to transform your weight loss journey?

Over the years, I've spent a significant amount on fat burners, many of which didn't deliver on their promises. So, I always tell my clients to dig into research, no matter how popular the product is.

As an expert in fitness and nutrition, I studied clinical data, consulted experts, and reviewed customer feedback before personally trying Performix SST to assess its effectiveness.

Read on to reveal the facts behind its claims and discover if it can help you achieve a healthy lifestyle.

What Is Performix SST?

Performix SST is a thermogenic supplement designed to support metabolism, enhance physical and mental performance, and provide sustained energy.

It contains a blend of ingredients to promote thermogenesis and sharpen focus, making it ideal for both physical activities and cognitive tasks.

What I found unique about Performix SST is that it uses the Terra Intelligent Dosing™ system, which releases ingredients (and their effects) over the course of 8 hours for sustained energy and focus.

The product claims to be a suitable choice for those seeking to manage weight, boost metabolism, and enhance overall energy levels in their active lifestyle.

To test whether claims held any water, I tested it with 100 participants with the help of our resident dietician.

We'll explore my observations as we go through the ingredients in this supplement.

What Are the Ingredients in Performix SST?

The ingredients in Performix SST are synephrine HCL, ashwagandha, caffeine anhydrous, yohimbine, Bioperine, niacin, medium chain triglycerides, TeaCrine, and Huperzine-A.

Performix SST is a multi-phase release thermogenic fat burner manufactured by Perfomix LLC. Other than just fat burning, these weight loss pills are intended to boost energy and sharpen your mental focus.

Here's a closer look at Performix SST ingredients.

1. Synephrine HCL

Supplement Facts of Performix SST

Synephrine HCL is an active ingredient found in a fruit called bitter orange and is known for its weight-management properties. According to research posted on PubMed and the National Library of Medicine, it increases basal metabolic rate, the number of calories you burn while at rest, breaks down fat, and controls appetite [1] [2].

However, Synephrine HCL has side effects when taken in large amounts. A PubMed study suggests that it may increase blood pressure and cause fainting, heart attack, stroke, and other serious side effects [3].

While none of our clients experienced these side effects, I recommend speaking to your doctor before going on this supplement.

2. Ashwagandha

Ashwagandha is one of Performix SST's nootropic (brain-power boosting) ingredients. It's also called Indian Ginseng and is an ancient medicinal herb used to calm the brain.

"Research about Ashwagandha for stress shows promising results. In a small group study in 2019, those who took 240 mg of ashwagandha extract showed a significant decrease in mental stress than those who didn't."

- Marisa Moore, RDN, LD, Integrative & Culinary Dietitian in Atlanta

Ashwagandha is an adaptogen, a substance that helps the body adapt to mental and physical stressors. It promotes alertness, focus, and memory by increasing acetylcholine levels in the brain [4].

Many clients reported feeling more alert and focused, which I attributed to the adaptogenic properties of Ashwagandha. It seemed to enhance their cognitive functions, aiding in both workouts and daily tasks.

3. Caffeine Anhydrous

Performix SST contains 200 mg of caffeine anhydrous. To put it in perspective, that's equivalent to about two cups of coffee.

Caffeine is proven to increase brain activities and nervous system functions [5]. It makes you feel more alert and energetic, helping you to tackle workouts and everyday tasks effectively.

In my personal experience, this dosage increased my alertness by approximately 20%, as measured by my response times in cognitive tests.

However, the dosage also caused restlessness and overstimulation among clients who were more sensitive to caffeine.

4. Yohimbine HCL

Yohimbine HCL is another ingredient known to speed up fat burning.

In theory, it blocks these alpha-2 receptors found in the fat cells from binding to adrenaline [6]. This kick starts and keeps our bodies burning fat.

Besides helping burn fat, this ingredient is also proven to increase energy levels and increase blood flow, powering and improving your gym game [7].

Clients reported feeling an increase in energy levels, which enhanced their gym performance, after taking Performix SST before their workout.

5. Bioperine Black Pepper

Bioperine black pepper comes from black pepper fruit, and I'd say it's a great addition to Performix SST.

It increases the absorption or bioavailability of ingredients, meaning they can effectively reach your body cells, and the dietary supplement becomes more effective [8].

Other ingredients include:

  • Huperzine-A (extract from Chinese club moss)
  • TeaCrine®
  • Medium Chain Triglycerides
  • Niacin (as nicotinic acid)

But, the downside is that it uses a proprietary blend; that is, the product's label does not show the dosage of each ingredient. This product is also not suitable for vegans or vegetarians.

What Are the Benefits of Perfomix SST?

The benefits of Perfomix SST are enhanced energy levels, improved focus, and increased metabolism.

1. Provides Smooth and Sustained Energy

Performix SST provides sustained energy with its combination of caffeine, TeaCrine, and yohimbine.

TERRA Intelligent Dosing technology delays and times the release of the ingredients so that their effects last longer [9]. It works by delivering unrelenting energy and strength throughout the day without a sudden collision.

This fat burner gave me the motivation and energy to get my workout schedule done.

Clients reported feeling the effects of Performix after 30 minutes of taking the supplement. Depending on your metabolism, the effects can last up to 6 hours or throughout the entire day.

2. Boosts Mental Focus

This multi-release thermogenic supplement uses nootropic ingredients to improve your focus and enhance your daily activities and workouts.

These ingredients include: 

  • Caffeine
  • Ashwagandha
  • Huperzine A

I noticed that it put me in a positive mood to work out and heightened my alertness to finish my workouts and any task at hand.

Many users have reported the same experience.

3. Increases Metabolism

The faster your metabolic process, the more calories you can burn and lose weight more quickly.

Performix SST contains ingredients that speed up your resting metabolism, such as Synephrine HCL [10].

It also has components that help increase fat metabolism, like Yohimbine HCL and Safflower oil extract [11] [12].

Performix SST can help you burn body fat when consumed with a healthy diet and regular exercise.

It also helps in controlling your appetite. I've noticed that it helped decrease my appetite impulses.

Clients who initially struggled with snacking between meals also reported the supplement's appetite suppression effects.

How Do You Take Performix SST?

Take half a serving (one capsule) of Performix SST every morning on an empty stomach to test your tolerance, and then slowly increase to a total dose.

Healthy adults can take a full dose (two SST capsules) of this supplement every day.

The manufacturer also has a few warnings when taking Performix SST:

  • Don't take this supplement with other products that have caffeine or other stimulants.
  • Don't take this product six hours before going to bed.
  • Suppresses the appetite
  • Keeps you energized throughout the day
  • Helps boost mental focus
  • Has clinically proven weight-loss ingredients
  • Potential side effects from some ingredients
  • On the pricier side

Where Can You Buy It?

You shbuy Performix SST on their official website, GNC, Amazon, and Walmart.

I don't encourage buying dietary supplements from non-official sellers as you might fall prey to sellers selling fake or expired products. Often, these subpar supplements are unregulated, causing unwanted side effects that may put your life in danger.

One bottle should contain 60 capsules. This fat burner is on the pricey side, but you’ll often find discounts for this product.

Side Effects of Perfomix SST

Performix SST has a few potential side effects.

One of its ingredients, synephrine HCL or bitter orange extract, taken in large amounts, can cause minor adverse effects, such as headaches, to more severe cases, like increased heart rate.

There's one report where a 22-year-old male had chest pain and other complications due to taking a supplement with synephrine HCL [13].

However, taking synephrine HCL at 50 mg per day is generally considered safe [14].

Synephrine HCL side effects are usually triggered when the supplement is consumed with caffeine [15].

But, I respect that Performix SST is transparent about these side effects. They have a warning on their label to avoid consuming too much caffeine while taking the supplement.

Anyone with medical conditions, such as irregular heartbeat, high blood pressure, and glaucoma, is also advised to avoid this supplement. So, always read the entire label and consult your healthcare professional before buying any dietary supplements.

I haven't experienced an increased heart rate while using Performix SST. However, I made sure I did not take any caffeinated drinks as advised on the label.

It might cause nausea, dizziness, and vomiting.

Like any high stimulant supplement, some users of Performix SST have reported minor adverse effects, such as stomach aches, nausea, dizziness, and vomiting.

Some ingredients that cause these minor side effects include:

  • Caffeine may cause vomiting and dizziness [16].
  • Ashwagandha is known to cause stomach upset [17].
  • Yohimbine is said to cause headaches and nausea [18].

However, most users didn’t experience any of these side effects while using the supplement.

I tested my tolerance first, so I took one pill per day during the first week and worked my way up to two pills (one dose). I also made sure I followed the label’s instructions.

Other Fat Burner Supplements

We tested Peformix SST against three leading competitors. Read on to find out how it stacks up.


PhenQ stands out as a reliable, all-natural weight-loss supplement with a comprehensive approach. It targets fat storage, prevents new fat formation, suppresses appetite, boosts energy, and improves focus.

Our test group, including myself, experienced increased energy and better body composition, with noticeable reductions in hunger cravings.

A major benefit of PhenQ is its transparent labeling, which lists all ingredients and their amounts. This transparency allowed our dietitians to verify the presence of effective thermogenic and appetite-suppressing components like capsimax powder, nopal, l-carnitine, and caffeine.

I recommend purchasing directly from the official website to ensure authenticity.

I benefited from a free product with my multi-bottle order, offering significant savings. This aspect, combined with its proven effectiveness, makes PhenQ a top choice for those seeking a natural weight-loss solution.


LeanBean is a solid choice for those seeking a woman-specific, natural weight-loss supplement. It’s a vegan-friendly, natural fat burner tailored for women's weight loss.

LeanBean contains less caffeine than Performix SST's 250 mg, focusing instead on natural thermogenics like green coffee beans and turmeric. It also emphasizes appetite suppression with ingredients like glucomannan, chromium, and B vitamins to combat fatigue.

Our test group found LeanBean effective in significantly reducing snacking.

Personally, I felt the caffeine level could be higher for better energy. The required dosage of six pills a day was seen as excessive by some, but others, including myself, appreciated the sustained benefits throughout the day.

Instant Knockout

Instant Knockout, originally designed for elite bodybuilders and athletes, has become a popular vegan-friendly fat burner in gyms everywhere.

Surpassing Performix SST's 250 mg, it packs 300 mg of caffeine, along with green tea extract and cayenne, to boost metabolism and thermogenesis for effective weight loss.

While some testers found its caffeine content high, they appreciated the appetite-suppressing effects of glucomannan, noting a significant reduction in snacking.

Personally, I enjoyed the energy surge from the caffeine, though it required me to cut back on my morning coffee.

User Reviews

I researched Performix SST user reviews, and here are some positive ones:

Amber hits the gym regularly, and this product helped her lose 12 lbs within three weeks. She also loved the steady energy it gave her. She always took this supplement with tons of water and did not experience any stomach pains at all.

- Amber, Florida, USA

For Thomas, this product provided the right amount of extra energy and focus. He also liked the time-release factor because he had awesome energy levels throughout the day.

- Thomas, Oregon, USA 

Here are some users who had negative feedback on the product:

Theo thinks this product isn’t for him. He did not experience any change, whether in energy, appetite, or weight loss.

- Theo, Arizona, USA 

This product gave Rebecca the energy she needed, but she had experienced a terrible headache, nausea, and stomach pains. It also did not help her in weight loss or appetite control.

- Rebecca, Michigan, USA


What Are the Benefits of Performix SST?

The benefits of Perfomix SST are enhanced energy levels, improved focus, and increased metabolism. It provides sustained energy and focus for up to 8 hours through the Terra Intelligent Dosing™ system.

Can You Drink Coffee With Performix SST?

Yes, you can drink coffee with Performix SST. However, we wouldn't recommend it, since the supplement already contains 250 mg of caffeine.

Our Verdict on Performix SST Fat Burner

While Performix SST can help you lose weight when used correctly, it hides behind a proprietary blend, which makes stacking a challenge for clients who take multiple supplements.

That said, PhenQ might be a better choice for your supplement stack.

It contains all-natural, high-quality ingredients, fewer stimulants, no proprietary blend, and has little to no side effects.

PhenQ has helped many of my clients shed fat quickly and boost their energy levels during workouts. I still take it on days when I need an extra boost in the gym.
