Yes, like any other supplement, pre workout will also expire. 

However, compared to most other supplements like whey protein, pre workouts last longer. That being said, they last shorter than some supplements like creatine.

In most pre workouts available in the market, you can see a ‘best before’ date before which the supplement gives the best result or in other words, stays maximum effective! After that expiry date, you may get a lower pump while working out, and may also face stomach discomforts.

If you let your pre workout stay mixed for longer hours, it may affect its efficiency and also, you may face certain health problems like gas trouble! 

So, if you too have the habit of mixing your pre workout in the mornings and taking it in the evening, you may have to think again. 

And we would suggest you mix the pre workout just half an hour or one hour before your workout session. By doing so, you can ensure that your body gets all it needs for an energetic workout session! 

How Long is Pre Workout Good for After Opening?

That depends on several factors such as ingredient mix, whether it comes in contact with moisture frequently, how well you store it, etc. 

But on average, you can expect your pre workout to last as long as nine months from the first day of use; That is more than how long some supplements last; and less than the shelf life of others. 

Furthermore, as time passes by, different ingredients of the pre workout last for different durations. For instance, vitamin B lasts longer than amino acids. Some other ingredients may last either longer or shorter.

So, rather than going bad as such, your body will receive the benefits of some ingredients, while missing out on some others!
