Synthetic Additive
HMB (ß-Hydroxy ß-Methylbutyrate),
1000 mg
Training in a fasted state has been suggested to accelerate both the breakdown and metabolism of stored fat. The downside: Fasted training may also degrade lean muscle mass.
Beta-hydroxy beta-methylbutyrate (HMB) is a metabolite of the branched-chain amino acid leucine that is Performance Lab® Sport Fat Burner’s featured nutrient for optimizing fasted training results. HMB is suggested to help by:
  1. Neutralizing muscle-damaging enzymes that are generated during fasted training;
  2. Enhancing muscle strength and maximal oxygen consumption while delaying lactic acid onset, helping to optimize physical performance and endurance in a fasted state;
  3. Promoting muscle growth by directly increasing protein synthesis within the mTOR pathway;
  4. Encouraging the body to preferentially use stored fat as fuel instead of muscle tissue during calorie restriction
HMB naturally supplies a balanced combination of muscle-sparing, muscle-building and muscle recovery bioactivities that may support lean muscle mass in conjunction with training, especially high-intensity interval training and cardiovascular exercise on a calorie deficit.
Research has linked HMB supplementation with lower levels of 3-MH, which is a marker of enzyme-induced protein degradation:
HMB Supplemenation
About Performance Lab® Sport Fat Burner HMB:

Coleus Forskohlii (as Forslean®) (standardized for min. 10% forskolin),
250 mg
Coleus Forskohlii is an Ayurvedic root herb that is the only natural source of its primary active ingredient: Forskolin.
Forskolin activates the adenylate cyclase enzyme that increases production and intracellular concentration of cyclic adenosine monophosphate (cAMP), a signaling compound that may help to promote desirable body composition by:
  1. Optimizing hormonal cell messengers that regulate metabolism, thermogenesis and anabolic muscle growth, including thyroid hormone and testosterone;
  2. Activating the enzyme protein kinase, which stimulates lipase to catalyze the breakdown of triglycerides: The building blocks of body fat
ForsLean® Action
Coleus Forskohlii’s synergistic, multi-pathway activity is suggested to help minimize body fat while maximizing lean muscle growth – supporting optimal body composition and the peak metabolic function that helps maintain a healthy weight.
Coleus Forskohlii
Forslean® Supplementation
About Forslean®
Forslean® is an advanced form of Coleus Forskohlii standardized to supply a minimum of 10% active forskolin. Forslean® is patented for shifting body composition away from fat and in favor of lean muscle, and has been shown to be safe, well-tolerated and effective in multiple clinical trials.
Researchers have linked supplementation with the Forslean® used in Performance Lab® Sport Fat Burner with significant reductions in bodyweight and significant increases in lean body mass:
Cayenne Pepper Extract (as Capsimax®) (standardized for min. 2% capsaicinoids),
50 mg
Cayenne pepper supplies active ingredients called capsaicinoids that are responsible for the pepper’s fat-burning effects. Among other bioactivities, capsaicinoids activate the sympathetic nervous system to release catecholamine hormones (epinephrine and norepinephrine) from the adrenals.
In Performance Lab® Sport Fat Burner, cayenne’s pro-catecholamine activity may assist with healthy weight management because catecholamines have been shown to:
  1. Stimulate beta adrenergic receptors that signal for cells to increase energy expenditure, helping to maximize calorie-burning during exercise;
  2. Signal for hormone sensitive lipase to promote fat breakdown (lipolysis), fat mobilization and fat oxidation before and after exercise
Cayenne peppers’ capsaicin is also notable because its metabolic effects are achieved without stimulants or related side effects, such as increased heart rate and blood pressure.
Cayenne Pepper
About Capsimax®:
A highly active extract standardized to 2% capsaicinoids, Capsimax® supplies chili peppers’ active ingredients for weight control in buffered OmniBead™ microspheres, which delay release of cayenne’s nutrition for absorption in the lower intestine – a step that eliminates the oral and gastric burning sensations that are sometimes associated with hot peppers.
Catecholamine + cAMP Synergy for Lipolysis:
Catecholamine-induced lipolysis appears to be more pronounced in visceral fat, in part due to the lipolytic activity of cAMP. Together in Performance Lab® Sport Fat Burner, Cayenne’s pro-catecholamine activity and Coleus Forskohlii’s pro-cAMP activity are intended to combine for superior lipolysis performance in visceral fat tissues.
Black Pepper Extract (as BioPerine®)(Standardized for min. 95% piperine),
2.5 mg
Black pepper extract supplies an active ingredient called piperine. Considered a thermonutrient, piperine is suggested to assist with weight control by:
  1. Optimizing thermogenesis, thereby increasing energy expenditure;
  2. Promoting efficient food metabolism, including enhancement of nutrient absorption;
  3. Inhibiting adipogenesis, the formation of new fat cells
Black Pepper
About BioPerine®
Performance Lab® Sport Fat Burner’s BioPerine® black pepper extract is a premium form standardized to supply a minimum of 95% piperine. Raw black pepper supplies between 3-9% piperine. BioPerine® is the only form of black pepper that is patented to increase the absorption, bioavailability and utilization of nutritional compounds, as well as the only form shown to be safe and effective in multiple clinical trials.

Who should take Performance Lab® Sport Fat Burner?
Performance Lab® Sport Fat Burner supports all weight control programs that include healthy diet and regular exercise. Performance Lab® Sport Fat Burner is customized, however, to optimize the fat-loss and muscle-gain results of fasted training.
What is fasted training? †
Fasted training refers to training on an empty stomach. Some research suggests that while in a fasted state, the body burns more fat during exercise. Fasted training has also been suggested to preferentially promote lipolysis in areas of stubborn visceral fat, such as around the abdomen in men and hips and posterior in women. These fat loss benefits may be attributed to fasting’s impact on insulin levels.
When food is consumed, blood sugar (glucose) rises. Insulin is released from the pancreas to manage this blood sugar, helping to convert it for immediate energy and store it (as glycogen) in muscles, fat and the liver as energy for later use. As part of these post-meal functions, insulin increases fat formation of fat while “turning off” lipolysis (fat breakdown).
After food is digested, the body enters a post-absorption state: Blood sugar and insulin levels both return to baseline because the stomach is empty. Exercising in this fasted state creates high energy demands, but the body has no glucose to use as fuel. Instead, during fasting the body burns through its glycogen stores – including visceral fat – to produce energy.
Possible drawbacks of fasted training include a reduction in exercise intensity and increased susceptibility to muscle and protein degradation. Performance Lab® Sport Fat Burner is designed to optimize fasted training results while minimizing these potential fasted training drawbacks.
Fasted training should only be done under the close supervision of a healthcare professional.
How do I take Performance Lab® Sport Fat Burner?
For best results take 2-4 capsules 15 minutes prior to training.
How should I take other Performance Lab® supplements during fasted training?
Performance Lab® Sport Pre-Workout and Performance Lab® Energy stack well with Sport Fat Burner, and may be taken 45-60 minutes prior to training. If training fasted, Performance Lab® Sport BCAA should be taken intra-workout or post-workout only, to avoid breaking your fast. Other Performance Lab® supplements should be taken post-workout to best optimize the fat loss benefits of fasted training.
Is Performance Lab® Sport Fat Burner safe?
Like other Performance Lab® supplements, Performance Lab® Sport Fat Burner is designed to be safe for long-term daily use, without the need for cycling. Performance Lab® Sport Fat Burner achieves this by using pure, potent ingredients that are dosed appropriately and in line with clinical research. Performance Lab® Sport Fat Burner’s clean formula design – free of GMOs, gluten, soy, colorants, preservatives and other additives – is also well-tolerated by the body, and safe for long-term use. Performance Lab® Sport Fat Burner avoids the use of caffeine and stimulants, further strengthening its safety and tolerability profile.
Why is there no caffeine in Performance Lab® Sport Fat Burner?
Some fat burner supplements supply caffeine and other stimulants, which may promote weight loss but may also be accompanied by side effects related to blood pressure and heart rate. Performance Lab® Sport Fat Burner is stimulant-free by design. Instead of caffeine, Performance Lab® Sport Fat Burner enhances metabolic performance via non-stimulatory pathways. Performance Lab® Sport Fat Burner is formulated to promote fat burning in a way that is safe and well-tolerated.
