Pre-workouts are great as they give individuals a significant energy boost before workouts.

Tests run on pre-workout, however, have indicated that pre-workout might have more chemicals in it than meets the eye. [1]

This can be alarming, especially if you're about to take a test soon.

So, can pre-workout show up on a drug test? We're here to answer that query and more.

The simple answer to this is, yes, there are some pre-workout supplements that may affect drug tests.

While most pre-workout drinks won't show up as they contain natural ingredients like creatine and caffeine, it's highly dependent on the pre-workout supplement that you're taking.

If your results are positive, the pre-workout powder you're taking likely has DMAA (Dimethylamylamine) [2]. It's added for fat-burning effects and can come in the form of many names such as:

  • Geranamine
  • Methylhexanamine
  • 1,3-DMAA
  • 4-Methyl-2-hexylamine

Recently banned by the FDA, if you're testing positive, there's a potential that DMAA is present. Other than DMAA, something else to take into consideration for the ingredient list is methylphenethylamine - another amphetamine-like compound.

Most pre-workout supplements, however, shouldn't have any of the above ingredients.

What Are The World Anti-Doping Agency (WADA) Guidelines

WADA is the organization that's in charge of testing athletes for the Olympics. They typically always have a list of all the banned substances, and if an athlete is tested with any of these substances in their blood flow, they get suspended.

Some substances listed include supplements such as testosterone and narcotics along with stimulants such as ephedrine. [3]

While it might sound straightforward, the list can be complicated as it lists substances by chemical composition.

When it comes to pre-workout, it can be complex as some supplement companies could slip banned substances other than protein powder and creatine to make it more powerful.

These supplement brands are also able to get away with this as they aren't required to list all the ingredients that they have on their label.

In some instances, the supplement could also be produced in the same facility as another supplement that has banned substances. This could cause other substances to result in a failed test.

Why Do Athletes Test Positive On Drug Tests? (Common Reasons)

There are multiple reasons why this could happen:

  1. 1
    Banned Substance Not Listed On Label 
    This is a common reason as there isn't a legal requirement for some substances to be listed on the label. With that, athletes could be consuming these ingredients without them even knowing.
  2. 2
    Missing Banned Substance On Label 
    Similar to the above, there's a possibility that individuals aren't even checking the label, so they might not have noticed the particular active ingredient.
  3. 3
    Consciously Using Them 
    Whether helping to reduce fatigue, pushing out more reps, or helping them with their workouts, it's not uncommon for athletes to consciously use these stimulants to help them with their training.

How To Be On The Safe Side? (Don’t Fail Your Drug Test!)

There isn't a failproof solution to this, but here are some guidelines you could follow:

  1. 1
    If you see a supplement that contains DMAA or something you're not familiar with, you can go to the World Anti Doping Agency website to see if it's prohibited.
  2. 2
    There's nothing wrong with checking with other individuals to see what they are taking and whether or not they've been tested for drugs.
  3. 3
    Educate yourself and stay in the know of a particular supplement and if it's approved. It's always good to know what you're taking and whether or not it's doing more harm than good for your body.
  4. 4
    Regardless of whether you're one of the active duty service members, an athlete, or just someone building muscle, you should know of not just the benefits but also the potential harm these supplements are having on your body.

You should not be worrying about whether or not they're drugs or have a negative impact on your health.

So, Is Pre-Workout Natty Or A Drug? (Our Findings)

'Natty' is slang for 'natural,' but it depends on who you're speaking to.

Some individuals might think that you can only call yourself 'natty' if no stimulants or supplements are consumed.

This can be contentious, however, as some of the supplements like creatine and nitric oxide are found naturally in the food consumed.

For those training regularly, 'natty' means that you're not taking any PEDs that are banned. This also includes anabolic steroids, amphetamines, and anything else that may be considered drugs.

Yes, it is possible for some individuals to be tested with a false positive. Even though the ingredients are not drugs, there could be traces of DMAA or other ingredients. 

Will creatine show up on a drug test?

Creatine is typically tested during a drug test, but it shouldn’t cause you to fail one. Just know, however, that if the concentration of creatine is below 20mg, the sample is usually rejected for testing.

Will beta-alanine show up on a drug test?

As it is technically amino acids and not a drug, it shouldn't show up on a test during drug testing.

How long does pre-workout stay in your system for drug tests?

As seen from the above, there are plenty of pre-workouts out there, and these workout supplements could contain ingredients that have the potential of causing you to fail your test - even if they aren't drugs.

Whether it be for health, building muscles, or training purposes, it's always best to consume approved ingredients and avoid taking pre-workouts or a supplement prior to your test.
