Where to Get It

Performance Lab Sport Pre-Workout is a nutritional supplement designed to be taken shortly before exercise. It’s intended to provide muscle-priming sports nutrition to help prepare for high-intensity training.

The manufacturer claims that it can help optimize fitness by increasing blood flow to muscles, enhancing muscle power, and improving physical endurance.

Like most other popular pre-workout supplements, it contains a blend of ingredients – including creatine, amino acids, cordyceps and more. It does NOT contain caffeine, however. Most pre-workouts do have caffeine, so if you’re looking for a caffeine-free version, this is a good choice.

The guide below will cover all there is to know about this supplement – starting with the claimed benefits.

What Sport Pre-Workout Claims to Do

Performance Lab Sport Pre-Workout is designed for athletic performance. The manufacturer claims that the product helps with:

Muscle Strength & Performance

The manufacturer claims that this product can help enhance physical performance and muscle strength.

There is evidence to support this claim. Creatine has a variety of positive effects on exercise performance. It helps produce more ATP energy in muscles, which can help to drastically improve high-intensity exercise performance. Creatine is extremely well-studied, and has showed performance-enhancing benefits in strength, muscle endurance, sprint ability, fatigue resistance, and more. These claims may seem bold, but they are backed up – notes that “Creatine is among the most well-researched and effective supplements.”

Creatine is the primary strength & performance enhancer in this product, but other ingredients may have benefits as well. L-citrulline may help to boost the effects of creatine, while reducing fatigue. Maritime pine bark extract may also play a role in exercise performance and nitric oxide production. More research is needed on some of these ingredients.


The manufacturer claims that this product can help enhance and extend physical endurance during exercise.

There is evidence to support this claim. Cordyceps, which is included in this product, is thought to increase the body’s production of ATP, a primary source of energy. Creatine, also included, can also help to produce more ATP energy and restore depleted ATP levels lost during exercise. Other included ingredients may have an effect on endurance, but these are the primary boosters.

Muscle Tissue Support

The manufacturer claims that Sport Pre-Workout helps to oxygenate and nourish muscle tissue, while simultaneously clearing out toxins, raising nitric oxide levels and enhancing blood flow to muscles.

There is limited evidence to support this claim. Pine bark extract can assist with vasodilation, potentially helping to increase blood flow and nitric oxide production. More research is needed for this claim.

What’s In It

One serving of Performance Lab Sport Pre-Workout (4 capsules) contains:

  • 140mg sodium
  • 1000mg creatine (as Creapure pH10)
  • 750mg cordyceps sinensis
  • 500mg L-citrulline
  • 250mg L-glutamine
  • 300mg L-carnosine
  • 350mg himalayan pink salt
  • 100mg maritime pine bark extract

Creatine Creatine is a molecule that’s naturally produced in the body, and also found in some foods and supplements. It can significantly help with exercise performance by enhancing ATP energy production during training.

Cordyceps sinensis Cordyceps is a type of fungus native to China that can also be produced in a lab. It’s thought to help improve exercise performance by boosting the body’s supply of ATP.

L-citrulline Citrulline is an amino acid that may help to reduce fatigue during exercise while increasing the production of nitric oxide.

L-glutamine Glutamine is an amino acid that may help to improve muscle hydration, potentially helping with post-workout recovery.

L-carnosine Carnosine is an amino acid that may help to increase tolerance to lactic acid buildup during exercise. More research is needed.

Himalayan pink salt – Himalayan pink salt may help to restore electrolytes lost during exercise, potentially improving hydration.

Maritime pine bark extract – Otherwise known as Pycnogenol, maritime pine bark extract may help to improve performance and recovery for athletes.

For Best Results

For best results, this product should be taken in combination with a healthy diet and regular exercise habits. Pre-workouts like this one may help to enhance energy and/or performance – but you still need to put in the work to actually see results.

Since this product contains creatine, you should drink plenty of water while using it. Creatine can draw water from the rest of your body into your muscles, which can contribute to dehydration.

Always use this product as directed, and do not take more than the recommended dose. Pre-workout supplements should usually be taken around 30-60 minutes before your workout begins. For extended workouts, some people choose to split the dose and take some half way through their exercise.

You should also speak to your doctor about this supplement. Due to the high number of ingredients, the potential for side effects or interactions is relatively high.

Potential Side Effects

This product contains many ingredients, so the potential for side effects is fairly high. Some potential complications include:

  • Creatine can cause bloating, dehydration, stomach pain, diarrhea and muscle cramping
  • Cordyceps can cause complications with autoimmune diseases and bleeding disorders
  • Citrulline does not usually cause side effects, but can interact with certain drugs
  • Glutamine can cause stomach upset, swelling, muscle pain, headache, dry mouth and more
  • Carnitine has no significant side effects
  • Pine bark extract can cause gut problems, mouth ulcers, dizziness and headache

Side effects are more likely with higher doses. Always use product as recommended. Speak with your doctor if you have concerns or questions.

Bottom Line

Overall, if you’re looking for a pre-workout, this seems to be a great option. It contains many ingredients that are proven to be effective workout boosters, and some other ingredients that have limited evidence to support their efficacy.

It does NOT contain caffeine – which could be good or bad, depending on your goals. Caffeine is an effective pre-workout ingredient, although many people prefer caffeine-free options.
