Does Pre Workout Get Old? 11 Crazy FAQs

Have you ever reached in the back of your cupboard and pulled out a dusty container of pre workout that look expired?

You might ask yourself, does pre workout get old? 

The answer is that it does. Like many powders and supplements, pre workout has an expiration date.

As a certified personal trainer, I’ll explain the ins and outs of how to handle expired pre workout.

Here’s what’s coming up. 

Is It Safe To Drink Old Pre Workout? 

It depends on a few things to see if it’s safe to drink old pre workout. Use your best judgment to determine if it’s ok to drink. 

There is some debate on this issue for sure. Sources like Total Shape say not to drink pre workout that has gone past the expiration date because it causes stomach cramps or bad gas. 

Those are two things you definitely don’t want before a workout!

Use the expiration date to provide information on the potency and quality of the pre workout. So use that as your first guide.

I haven’t experienced these symptoms after drinking old pre workout I found way back in the cupboard. But that doesn’t mean it can’t happen to you.

Drinking expired pre workout doesn’t have many safety concerns, but there are a few stand out things to look for.

The first is that old pre workout doesn’t mix as well as fresh pre workout.

Old Pre Workout May Not Mix Well 

It’s common for a bit of old pre workout to get left behind in the glass after mixing it.

I had a personal experience with this.

I had some old pre workout from a few years that looked stale and gritty. The powder did not mix well at all.

During my workout I felt like it wasn’t doing its job because I wasn’t getting that same oomph I usually got. 

If you notice that there’s a lot of powder that’s left undissolved even after you’ve stirred, then think twice before taking it!  

Signs That Your Pre Workout Is Not Ok 

Mold

If you open your pre workout and find discoloration and any kind of growth then throw it away.

If you have no choice but tot take it, then know that mold is a fungus and it won’t kill you to eat it…but it tastes horrible and can seriously upset your stomach!

Use at your own risk trying to scoop around the mold to get to the untouched powder. 

Bad Smell

Your pre workout may contain certain chemicals or ingredients that produce an odor from being stored improperly. Later on I talk about how to properly store pre workout.

If you open the container and it has a funky smell, then don’t drink it! Chances are if it smells bad that it’ll taste much worse. USe at your own risk if you have no other options.

But the best thing to do would be to toss it. 

Bad Taste

If you drink the pre workout and it tastes funny, then check the expiration date. Bad taste can come from when an ingredient goes bad.

Use at your own risk if you can’t be without it. But the best thing would be to throw it away and get a fresh one when you can. 

Bad After Effects

If you get stomach cramps or gas after drinking expired pre workout, then don’t take it again. If you must take it, then prepare to deal with the unwanted effects.

The best thing to do would be to throw it away.

Bad Performance

When you take a fresh pre workout, you feel its effects no doubt. It gives you focus, pimp, and energy.

However, certain pre workouts contain amino acids that can decay over time. It it’s expired, then it will lose its potency so you feel less of it during your workout.

If you notice that do be the case replace it for a fresh one.

How To Keep Your Pre Workout Fresh 

Keeping your pre workout fresh is in your best interest, because it does not come cheap! Pre workout has a shelf life of 18-24 months, but double check the expiration date to be sure. 

Life happens and sometimes we may leave the bottle open or store it in an inappropriate place. But proper storage of your supplements is important to keep their potency and freshness.

Use these tips to maintain your pre workouts freshness for as long as possible. 

  • Open When Ready to Use. Do you have a regular schedule to workout? Have a pre workout ready to go! Don’t open the seal and leave it unused for weeks or months at a time.
  • Keep the Silica Packet. Some pre workouts contain a silica pack meant to absorb extra moisture and keep the powder fresh. Of course, keep the pack in the powder for maximum freshness.
  • Storage is Key. Where do you keep your pre workout? If it’s in your gym bag, it runs the risk of being too warm. If you keep it on your countertop it could be exposed to sunlight.

    Store your pre workout in a cool, dark place because air and light exposure can cause clumping. Putting it in the refrigerator is ok, and may in fact be the best place. 
  • Keep Water Away. Water can splash into the open container. Slight water exposure also happens when you unscrew the lid. The powder gets exposed to moisture from the air.

    Some ingredients are more water-retentive at room temperature, so you could see more clumps if you keep it on the countertop.
  • Seal Tightly. No surprise here, but close the lid after you’re done using it. If you leave it unscrewed, first off, it’ll make a mess if you spill it.

    Second, the product will get air exposure and moisture or bacteria could get into the pre workout. This will lead to clumping, mold, bad smell, or bad taste. 

Fix Your Clumpy Pre Workout 

Ever opened your pre workout and it had small balls of powder stuck together in clumps? It’s not a good look when you expect it to be smooth. 

Nothing to worry about though. Pre workout can naturally begin to collect moisture as it ages, so it clumps together. There’s three ways you can fix your clumpy pre workout.

Scoop it out of the container, and if you get a few clumpy pieces break it up with a spoon. Add water and mix well. Break up any remaining clumpy pieces with a spoon. 

An alternative way is to seal the lid of the pre workout container tightly and shake it for 10 seconds. Careful of all the powdery dust in the air as you open it. The vigorous shaking should break up any clumps in it.

If you’re looking for a more quick and extreme approach, put the clumpy pre workout straight into a blender. Add the contents and pulse until it’s smooth. Clumpy pre workout be gone!

Is It Ok to Premix Pre Workout?

pre workout get old

Yes, it’s ok to premix pre workout, but only for a certain amount of time. 

First let me explain three types of pre workout mixers.

You have the dry scoopers, who put the scoop directly into their mouth, drink a swig of water, and swish it around to mix it. Not everyone’s cup of tea though.

This has grown in popularity on social media, and all the hardcore lifters are doing this. I tried it too, and it was not pleasant.

Next you have the “mixers”, who mix the powder with water or BCAA’s and drink it before or during the workout. It’s best to drink pre workout up to 30 minutes before lifting. Don’t take pre workout if you’re not going to do physical activity. 

Finally you have the pre-mixers, who make a serving and leave it on the counter or in the fridge. 

If you can’t make it to the gym, or something comes up and you can’t go as planned, don’t worry. 

The good news is that most pre workouts remain dissolved for up to 12 hours. It will start to separate though, if not consumed after that. If you leave it refrigerated for longer than 12 hours, it’s probably best to get a fresh scoop.
