Like any supplement, pre-workouts will typically have a use by date printed on the tub. Pre-workout supplements tend to go bad if they are made with certain ingredients like fatty acids or fish oil, or ingredients that absorb moisture. If your pre-workout has gone bad, you shouldn't take it anymore because it's unlikely to be effective and can make you sick. If your pre-workout is beyond the date, yes it has expired. Most ingredients will work best within the date but some people will use the supplement anyway.
There are times that you shouldn't use a past date supplement; for example, if you have moldy pre workout. This should be immediately disposed of; there may be some side effects when you consume expired pre-workout like gas or an upset stomach.
Typically you will only mix your pre-workout right before using, but if you prep yours before work, there shouldn't be any problems. An ingredient that could degrade is creatine, so instead you could take a capsule form of creatine if you're worried about losing the benefits.
If your pre workout is significantly past its use by date, it might cause some issues like gastric distress which is probably something you want to avoid in the gym. This should pass pretty quickly, however it is unpleasant and should be avoided.
In some cases, clumpy pre-workout is bad and may indicate that it is past its usable date. However, if it is not past the date, you may need to blend the powder to get rid of the lumpy texture or you can break it up with a knife and that will help fix your clumpy pre-workout.
