What You Need To Know About Performix SST

There are several stimulant ingredients in both formulas of the product, which will help to boost the metabolism and burn more calories. Bitter orange extract and its constituents, including synephrine, have been linked with numerous side effects, and its safety has been questioned by the Mayo Clinic.

Bioperine will increase the uptake of these stimulant ingredients into the blood stream, making the product have a stronger effect with the same quantity of active ingredients.

There are also some ingredients that affect hormone levels in the brain, including cortisol. Reducing cortisol levels does help with stress, but has also been linked with reducing cravings for food and binge eating or emotional eating.

Whilst this may not help all dieters, some people will find they have reduced cravings, making it easier for them to follow a calorie controlled diet.

The powder form of Performix SST has a few different ingredients that are not used in the capsule form of the product. These extra ingredients seem to be tailored more towards people who are exercising regularly as well as dieting. Choline supplements are thought by some to delay fatigue and improve endurance, which would help regular gym-goers to burn more calories in their workout, whilst delaying exhaustion.

What Are The Side Effects Of Performix SST?

There are numerous ingredients used in Performix SST that could cause side effects. Bitter orange extract and synephrine are particularly dangerous. For a full list, please see the Side Effects tab below.

How Much Does Performix SST Cost?

Performix SST doesn’t seem to be available from online retailers such as and GNC anymore. This is likely due to the dangerous ingredients leading to the product being pulled. Some users are still selling it on eBay, however, we would not recommend you purchase this products anyway.

Our Verdict On Performix SST

Performix SST contains a wide variety of ingredients, including numerous stimulant ingredients. The two forms of the product offer slightly different formulas; whilst the capsule contains bitter orange extract, rather than just synephrine, the powder option contains some other ingredients, such as choline and cAMP.

Both versions of the product have overwhelmingly positive customer reviews, with very few reported side effects.

However, the lack of reported side effects from customers may be because the manufacturers have released a long warning notice of who should not use the product for health reasons. In general, it does seem that a wide array of side effects is possible.

Yohimbe and Bitter orange extracts are both strong ingredients that can cause a variety of side effects, some of which can be serious. Overall, whilst the product does seem to be effective, it can also cause serious side effects. Considering this, as well as the cost of Performix SST, this product can not be recommended to consumers in general.

Therefore we reject Performix SST and do not recommend it to our readers.

What Does Performix SST Claim To Do?

According to the official website, Performix SST provides Ballistic Energy, Fat Metabolism and Precise Mental Focus.

It contains several fat burning ingredients that boost the metabolism and help to burn more calories. These ingredients also boost energy levels.

Does Performix SST Work?

The customer reviews from the retail sites where Performix SST is sold are almost exclusively positive. Customers report that the product is strong and effective, but does not seem to cause side effects in the majority of cases. Many of the reviews do focus upon the energy and mental focus provided by each dose, but also mention appetite suppression occasionally. Consumers also mention some weight loss.

The ingredients list supports the testimonials from satisfied customers- the ingredients used are a mixture of strong stimulants and other performance enhancing ingredients that should delay fatigue, aid recovery post-exercise, and boost energy levels and mental focus.

However, the product does come with a long list of restrictions of who should not take Performix SST. Consumers who ignore this advice will be much more likely to experience a range of side effects. The product should also be cycled according to the directions for use, again to minimise the chances of side effects occurring.

What Are The Ingredients of Performix SST?

The ingredients used in Performix SST are listed below. The product is available as either a capsule or a powder, but the two ingredients lists are slightly different. Both contain proprietary formulas, and so the individual quantities of many of the ingredients are unknown.

For the capsule based product, the ingredient quantities provided are per serving of two capsules. Each bottle provides 30 servings. For the powder based version of Performix SST, the daily serving is three scoops, with each tub providing 30 servings.

Performix SST Capsule Ingredients

  • Niacin (as Nicotinic Acid) 10 mg (50% RDA)
  • Vitamin B-12 (as Methylcobalamin) 1,000 mcg (16,667% RDA)

Performix™ Suspension Super Thermo Complex (1,172mg)

  • Caffeine Anhydrous [200mg]: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism. The effects shown in studies are small, and some studies are inconclusive.
  • Sensoril® Ashwagandha (Withania somnifera) extract (root/leaf), [std. to 8% Withanolides, and 32% Oligosaccharides]: Sensoril® is a branded formulaic extract of the Ashwagandha plant. It is thought that its use lowers cortisol levels in the brain and body. Cortisol is a hormone produced during moments of stress, which has been associated with increasing weight gain, and making weight loss more difficult.
  • Advantra Z® Bitter Orange (Citrus aurantium) extract (fruit), [supplying synephrine, N-Methyltyramine, Hordenine, Tyramine, and Octopamine]: Bitter orange peel contains numerous naturally occurring stimulants and has been proven to raise the metabolism and aid weight loss. However there are some concerns about its safety.
  • Synephrine HCl: Found in Bitter Orange peel. A review of numerous studies concluded that use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks.
  • Huperzine A (Huperzia serrata) extract (aerial parts): Huperzine-A is thought to be a cognitive enhancer. Because of the relatively long half-life of this compound, its use should be cycled, with breaks in usage every few weeks.
  • Yohimbine HCl: Some studies have noticed increased blood concentrations of free fatty acids in participants who use yohimbine, suggesting increased rates of lipolysis. However, the Natural Medicines Comprehensive Database has stated that there is insufficient evidence to claim it aids in weight loss.
  • Mucuna pruriens extract (seeds), [std. to 40% L-DOPA]: It is used for treating anxiety but, there is little clinical evidence to support its use: the active ingredient is levodopa (l-dopa), which can affect the levels of dopamine in the brain. However, most L-dopa is broken down in the body before it can reach the brain, unless combined with specific chemicals that are not present in Mucuna Pruriens.
  • BioPerine® Black Pepper (Piper nigrum) extract (fruit), [std. to 95% Piperine]: This patented Black pepper extract is used for increasing the bioavailability of nutritional compounds. In other words, it increases the amounts of nutrients that are absorbed into the body in the digestive tract. It may also increase the absorption of various drugs, which may lead to potential side effects.

Performix SST Powder Ingredients

  • Niacin (as Nicotinic Acid) 10 mg (50% RDA)
  • Vitamin B-12 (as Methylcobalamin) 1,000 mcg (16,667% RDA)
  • Calcium (as Calcium Silicate) 27 mg (3% RDA)
  • Sodium (as Sodium Bicarbonate) 115 mg (5% RDA)
  • Potassium (as Potassium Bicarbonate) 488 mg (14% RDA)

Performix™ Suspension Thermo Complex (1,974mg)

  • Choline Bitartrate: Athletes sometimes supplement Choline to delay fatigue and improve endurance. However, there is little clinical evidence to suggest that the effect is significant.
  • Oleoylethanolamide Powder [std. to 15% Oleoylethanolamide]
  • Caffeine Anhydrous [200mg]: As described above.
  • Sensoril® Ashwagandha (Withania somnifera) Extract (root/leaf), [std. to 8% Withanolides, and 32% Oligosaccharides]: As described above.
  • Synephrine HCL: As described above.
  • Huperzine A (Huperzia Serrata) Extract (whole plant): As described above.
  • Yohimbine HCL: As described above.
  • 3’,5’-Cyclic Adenosine Monophosphate [98% cAMP]: cAMP is known to affect numerous cellular processes, including the metabolism of carbohydrates and fats.
  • Bioperine® Black Pepper (Piper nigrum) Extract (fruit), [std. to 95% Piperine]: As described above.

Does Performix SST Have Any Side Effects?

The manufacturers have provided a cautionary list describing who should not use this product due to health concerns. However, they do not go into much detail about what side effects could be caused by Performix SST.

There are numerous ingredients used in Performix SST that could cause side effects.

The product contains both bitter orange extract and synephrine, which is extracted from bitter orange. Side effects associated with the use of Bitter Orange extracts include increased heart rate and increased blood pressure, heart palpitations, fainting, and even heart attack and stroke in healthy patients. The Mayo Clinic has recommended avoiding use of Bitter Orange extracts because in their opinion, the risk of using the product is not worth the pay-off of any potential weight loss.

The effects of synephrine and other bitter orange extracts are enhanced when combined with caffeine. Consuming large quantities of caffeine can lead to headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness, and insomnia.

Ashwagandha can cause stomach upset, diarrhoea and vomiting, but is generally thought to be safe for short term use. Yohimbe can cause a wide range of side effects, including stomach upset, excitation, tremor, sleep problems, anxiety or agitation, high blood pressure, a racing heartbeat, dizziness, stomach problems, drooling, sinus pain, irritability, headache, frequent urination, bloating, rash, nausea, and vomiting. High doses can cause more severe effects.

Choline Bitartrate, which is only present in the powder form of this product, is generally safe in appropriate quantities, but can cause sweating, a fishy body odour, gastrointestinal distress, diarrhoea, and vomiting.

The consumption of Huperzine A can lead to side effects such as nausea, vomiting, sweating, blurred vision, slurred speech, restlessness, loss of appetite, cramping, increased saliva and urine, inability to control urination, high blood pressure, and slowed heart rate. This ingredient is not suitable for long term use.

Do not use if pregnant, nursing, or plan on becoming pregnant.

This product is intended for use by healthy adults over the age of 18 and should be avoided by those sensitive to caffeine or other ingredients that have known stimulant effects.

Contains caffeine.

Do not use this product continuously for more than 8 weeks.

Do not combine with alcohol.

Not intended for use by those with a medical condition.

Use only as directed. Do not exceed recommended daily intake.

Do not consume synephrine or caffeine from other sources, including, but not limited to, coffee, tea, soda and other dietary supplements or medications containing phenylephrine or caffeine.

Consult a physician or licensed qualified health care professional prior to use if you are pregnant or nursing, or if you are taking medication including, but not limited to, MAOI inhibitors, antidepressants, aspirin, nonsteroidal anti-inflammatory drugs or products containing phlephrine, ephedrine, pseudo-ephedrine, or other stimulants, or if you have a medical condition including, but not limited to, heart, liver, kidney, or thyroid disease, psychiatric or epileptic disorders, difficulty urinating, diabetes, high blood pressure, cardiac arrhythmia, recurrent headaches, enlarged prostate, or glaucoma.

Discontinue 2 weeks prior to surgery or if you experience rapid heartbeat, dizziness, severe headache, or shortness of breath.

Do not use if safety seal under cap is broken.

Keep out of reach of children.

Are There Any Customer Reviews For Performix SST?

Customers have left numerous positive reviews on, one of the sites that sell Performix SST.

I’ve used many pre workouts & energy enhancers throughout the years. The difference between Performix and other so-called pre-workouts is Performix has the longest stable energy rise than anything else I’ve experienced. I was amazed by how I was able to have so much energy in the gym and even an epic day following. I also had incredible mental focus. 10 stars!

I absolutely love these little pills! They look crazy cool because you can see what is inside them and they give you intense energy!! I alternate between 1-2 pills a day depending on how I feel when I wake up. If I’m gonna workout I take 2 if not I take 1 because the energy from 2 will force you to workout lol I would recommend these definitely! Helps my workout, gives me energy, and I’ve noticed weight loss (:

This was awesome. Energy in a capsule. I took it right when I woke up before I ate. I wasn’t hungry for 3.5 hours and I had a burst of energy that literally forced me to go running…in a windstorm. I would definitely recommend this product.

Does Performix SST Offer a Money-Back Guarantee?

No money back guarantee is offered by the manufacturer, as they do not sell the product directly themselves.

20 comments on 'Performix SST'

  1. I tried the SST Burn. A blue liquid berry flavor that is suppose to burn fat. It’s current 3 am and I can not sleep my stomach is in pain and my heart is beating rapidly. The GNC employee stated the SST Burn did not contain any caffeine so I took it before my workout and my preworkout I usually get but after the gym. I started feeling dizzy and sick after my workout and I can’t fall back asleep because my heart is racing. DO NOT RECOMMEND!!!!

  2. I have taken this off and on for a year. It is great for energy & focus but I sweat all the time (even sitting). I have just found out that a person should only be on it for 8 weeks at the most. Wish the people selling it to me would have told me. I have stopped taking it for a week now and I can’t hardly keep my eyes open. This is HORRIBLE. Pls help, I don’t know what to do other than let my body re-adapt to NOT taking it. I will never take this again.

  3. I’m 28 year old and I take this in the morning around 3am and go to work I don’t go to the gym until after work around 5:15pm. Sound I wait to take this?

  4. After reading the reviews, I’m afraid to take it, I do have high high blood pressure and get acids with lots of foods, I’m afraid this may no be for me, I am a 63 yr young person, but as the years are going by I hardly have any energy at all, I went to GNC and this is what they recommended for, should I take just one or none at all? They did offer my money back within 30 days

    1. I have really bad acid reflux that can flair up. This product made me feel like i was nearly having a heart attack my chest pains were so bad. I am only 18. I would not recommend. They do have a PERFORMIX STIMFREE that may be better for you.

  5. After reading the reviews, I’m afraid to take it, I do have high high blood pressure and get acids with lots of foods, I’m afraid this may no be for me, I am a 63 yr young person, but as the years are going by I hardly have any energy at all, I went to GNC and this is what they recommended for, should I take just one or none at all?

  6. Just took my first half dose – one capsule this morning. I am a 55 year old type two diabetic with reasonably controlled blood sugar on oral medication and insulin with an A1Hc of 7.1 as of my last check up two weeks ago. Blood sugar was a little high (for me) at the time of taking the capsule after eating a small plate of roasted chicken with some stuffing so I took it with both fast acting and long term insulin as prescribed by a physician. Normally my blood sugar would have dropped into the 90 – 120 range within an hour. Blood sugar two hours after taking the capsule was 301 so I took more insulin. An hour later, it is 366. Just took more insulin. If it keeps going up in the next hour over 400, I will have to go to an emergency room. Please avoid this product if you are a diabetic.

  7. I love this product. I was having trouble losing some water weight and jump-starting my weight lifting workout. I am a healthy 32 year old with no existing health conditions. I took one pill a day to start the product, and at first the mental focus side effect can be intense (like you may be able to hear sunlight), however, my body got used to it in two days and I was able to take 2 pills a day. I lost the water weight and have exceeded my workout goals. I have never looked better in my life and it’s all thanks to this product. No adverse side effects, but you do need to drink plenty of water. Rich foods may not agree with this product, however I was committed to a chicken breast/broccoli high protein diet and had no issues. This should only be taken when you are committed to a workout routine.

  8. I used this product and felt great only side effect but got horrible diarrea, probably the red peppers in it. Burning sensation. Im taking them back to the store.

  9. A patient was treated at my hospital recently for a massive heart attack after taking this supplement regularly for several days. He was a healthy 22-year old with no medical conditions and not taking any other supplements or medications. As a pharmacist I strongly warn anyone reading this NOT to use this product.

  10. I have been nauseated for the last twelve hours from this crap! Excess saliva and heartburn. Great diet pill, who can eat when you feel like this?

  11. Started a cycle on this yesterday, about 2 hours after lunch and felt great. I had loads of energy and focus. I took the same dosage today on an empty stomach, and felt incredibly anxious and a bit short on breath for about 30-45 minutes after. After that time passed however, i got the same feeling as yesterday, and I’m willing to try to finish the cycle for at least this week. MY ADVICE IS BE CAREFUL WITH THIS PRODUCT, STAY HYDRATED, AND you may want to take it with or after food

  12. at first, I started out with half of the dose (1 pill) and it felt fine but it didn’t give me a major boost of energy. Today, I took the regular dose of my energy and right as I took the two pills my whole body turned red along with itching and rashes and I feel awful. I do not recommend this pill it all. also there are so many bad side effects such as heart attacks even for the most healthiest people

    1. Where did the rash occur? I have had a very slight rash on my face and chest after I have been working out…should i speak to my doctor

    2. Your reaction could have been due to the niacin load. Niacin (and forms of) is well known to cause flushing, rash, and/or tingling/itching. Though not life threatening, it is certainly not comfortable. Taking a large dose of it will cause this with many people. I know it says 50% of daily allowance, but I have not seen or taken products with nicotinic acid as the niacin base. Straight B-6 is niacin and is, generally, tolerated better than many other forms.
      Or…it could have been an allergic reaction to one of the herbal ingredients. It would be interesting to see what an independant investigation from a certified lab would find.

    3. I had the same issue when I took this product for the second time! I have the powder and I drank it around 2 pm and went and ran some errands and I was feeling fine (I only did two scoops because I did three my first try of it and I was up for almost 2 days), but when I got back from running some errands I went for a run outside. I mad it one mile down the road before my feet started itching REALLY bad! To the point where I wanted to cry and didn’t even want to run back home. When I got home, I jumped in the shower, but my ENTIRE body broke out in a rash and I was itching like crazy! Once the itching started to go away, I couldn’t stop my body from shaking. All of this last for about 45 minutes total. I laid down and tried to relax and stay calm and finally it went away, but it was the most horrible thing I have ever experienced. This first day I took it, I did three scoops and nothing like this happened. It is the strangest thing!

  13. I just used this product today. I took it at about 8 am & within minutes I broke out in a straight sweat & my face turned beat red. After a half hour my body got so cold & I was shivering badly. my face remained red for about 7 hours. I did go to the gym though & you can notice & feel the difference for sure. also I was extremely concentrated on the tasks I was doing. if you can withstand a beat red face & the feeling of nausea throughout the day then it’s a good one. I used the performix iridium capsules

  14. i just started the supplement, and GNC offer money back within 30 days. I have lots of energy. They do have the stim free one as well.
