Strongest Pre-Workouts on the Market with the Most Caffeine

Strongest Pre-Workouts on the Market with the Most Caffeine

Now this is something close to my heart! I absolutey love caffeine and pre-workouts, so I was excited at the chance to put together a huge list of some of the top selling pre-workouts by caffeine level. So no matter if you are looking for lower caffeine pre-workouts or want to be stimmed out of your mind, we have the pre-workout for you!

Strongest Pre-Workout Supplements on the Market

100-200mg Caffeine Pre-Workout Formulas

This amount of caffeine is best for those looking for a small boost in energy or those that are more sensitive to caffeine. Users of this amount of caffeine are normally beginners. This is what we recommend for these users.

200-300mg Caffeine Pre-Workout Formulas

This is the most common range of caffeine that can be found in pre-workout supplements. Most pre-workouts on the market today fit into this range of caffeine. But many, along with this caffeine range, also include other stimulants that make them feel much stronger. Here are our top supplements in this range.

300-350mg Caffeine Pre-Workout Formulas

Now once you get over 300mg of caffeine, you better be experienced! This is when things really go to the next level with energy and focus. Any pre-workout is this category is next level and was formulated for those that love caffeine and everything stimulant.

400mg Caffeine Pre-Workout Formulas

Okay...so you have taken every pre-workout out there and nothing is strong enough for you. Then welcome to the ultimate pre-workout category. The 400mg per scoop pre-workouts. It's rare to find anything with this amount of caffeine, but there are some supplements out there. And we have the perfect one for you.

500mg Caffeine Pre-Workout Formula

Alright...the time is here. This level is the highest we sell in terms of caffeine levels...500mg! Now this isn't straight caffeine though. It uses caffeine anhydrous, caffeine citrate and dicaffeine malate. The total between all three types is 500mg of caffeine!

600mg, 700mg, 800mg, 900mg and 1000mg Caffeine Pre-Workout Formulas

I personally haven't seen many pre-workouts with anything to this level. The last one I saw was Metabolic Nutrition ESP, which was 500mg of caffeine. I have never seen or taken anything with more than that per scoop or serving.

Now if you still need more caffeine, you have a few options. These are our recommendations:

  1. Take a break from stimulants. Just 1-2 weeks off of stimulants can make 200mg feel like 500mg. I personally get off caffeine during vacations or work trips. I use that as my fast from caffeine.
  2. Double your dosage. Now this is normally not recommended by the manufacturer of by us. And I still don't recommend it. I do know of many customers that do this though. All of a sudden that Panda Supps Skull pre-workout jumps from 400mg of caffeine to 800mg of caffeine.
  3. Look at the other stimulants in the pre-workout. Many of the 300mg pre-workouts we sell hit so much harder because of other stimulants. The main one being DMHA. It's amazing what that stimulant does on it's own with no help from caffeine.
