The 12 Best Pre Workouts with 200-600mg Caffeine (200mg, 300mg, 400mg, 500mg, 600mg)

by Nader Qudimat
Updated October 17, 2022

Caffeine is one of the oldest ingredients in pre workouts.

This grandfather of a stimulant is the foundation of energy.

It used to be required to take multiple servings to get your desired amount of caffeine. 

But luckily these days, it's never been easier to find pre workouts with a specific amount of caffeine. 

From 200mg, all the way up to 600mg. 

And of course, a lot of these pre workouts contain other stimulants that add to the energy.

Best Pre Workout with 200mg Caffeine

This used to be the standard dosage for caffeine for most pre workouts but they would require multiple scoops in order to get enough of the muscle building ingredients like citrulline. 

However we've found a pre workout that contains 200mg with full clinical dosages of ergogenic aids.

Very few pre workouts out today contain 200mg like Bulk by Transparent Labs.

But just because it contains 200mg, it doesn't make it weak as this might be enough for you. 

Along with caffeine, Bulk uses theanine with other ingredients that make it beneficial for mood and stress.  

This pre workout has been a popular choice for many years and with its time-tested formula, it's not something that would turn into something irreverent.

Bulk has a solid foundation of vitamins and minerals that is necessary for optimal performance, meaning it'll help optimize testosterone production, muscle building hormones, and more. 

It has zinc, vitamin B6, B12, and even boron citrate. 

With a mix of ergogenic aids, including citrulline malate, beta alanine and betaine anhydrous, these will help increase power and strength.

There's also ingredients that will help with focus, with Alpha GPC and L-Tyrosine. 

Bulk is a perfect pre workout that does everything correctly and keeps the caffeine at a minimum with 200mg of caffeine coming from two sources. 

Uses a solid foundation of vitamins and minerals

Multiple sources of focus and performance enhancers
Includes theanine which isn't liked for it's calming effects (but makes energy smoother)

Pre Workouts with 300mg Caffeine

Thanks to the other stimulants that can be included, 300mg caffeine pre workouts are more than enough. 

The problem with higher dosages of caffeine is that it can interfere with sleep because of the half life that makes it take all day for our bodies to get rid of the caffeine. 

With 300mg of caffeine, this can be effective as other stimulants are combined with it...

With plenty of pre workouts that saturate the market, it makes it more difficult the find the right one. 

But it seems like overnight Huge Nutrition turned Wrecked into one of the best pre workouts to get. 

Containing over 17 ingredients with 30 gram scoop servings, Wrecked is one beast of a pwo to consider. 

It was upgraded in 2022 and now the servings contain even more ingredients. 

There are two sources of caffeine here, 250mg coming from caffeine anhydrous and the other 75mg coming from di-caffeine malate.

As far as stimulants go, it contains caffeine along with other standard stimulants.

It also contains eria jarensis, which is a form of PEA and it can provide a nice sense of euphoria but it doesn't have any side effects. 

Wrecked is a good choice whether you're used to taking hardcore pre workouts and looking to take a break from DMHA / DMAA or want something that works very well without overdoing it with stimulants.

Gulag is one of the most surprising pre workouts we've tested so far. 

No one likes to see the proprietary blend but Gulag is one of the few good pre workouts that have one. 

This is one of the pre workouts that really gives me a euphoric vibe that gives such a big mood uplift.

The ingredients in here are some common ones that we've seen in the hardcore pre workout, but the experience is totally different. 

From the first few minutes of taking this, there's a little bit of energy that kicks in but soon after that, there's such a big effect on mood. 

It's almost questionable but it's not overwhelming to the point where there's a crash.

Gulag gives off a very happy and productive mood that makes us want to workout and lift heavy stuff. 

I personally recommend only using this once every week or every few weeks as it seems to work well when used on special occasions.

Pre Workouts with 600mg Caffeine

Any pre workout with 600mg of caffeine is going to keep you up at night if you take it too late. 

For most people, caffeine should be consumed before 12 pm to ensure it doesn't interrupt your sleep routine. 

It can be tricky with 600mg of caffeine because of how long it lasts and it would also contain other stimulants. 

In this list, we have two pre workouts: Hooligan and Assassin. 

Assassin contains DMHA, eria jarensis and alpha yohimbine, which all make the energy much more intense and is made for stim junkie fans. 

While Hooligan doesn't contain any banned substances and has crazy focus and pumps. 

Both pre workouts are great but if you want something with potent energy, then Assassin is the way to go.

How much Caffeine is in Pre Workouts?

As you can see from this guide, you'll find pre workouts with different amounts of caffeine.

Depending on which one you go with, they can range from 200mg to 600mg.

Some pre workouts do go as high as 700mg, but really there are few to no studies on those dosages and it gets closer to the zone where side effects are likely to be experienced.

And most of these pre workouts contain other stimulants that are stacked with caffeine, making them hit much harder with intensity you wouldn't experience otherwise. 

What Are The Types of Caffeine?

There are a few types of caffeine and these are the main types you'll see.

  • Caffeine Anhydrous
  • Di-Caffeine Malate
  • Caffeine Citrate

These types of caffeine are going to be under different names sometimes, and sometimes they are used in patent forms.

Ideally, you'll want a pre workout with a mix of these 3 types of caffeine as the timing of each one varies.

Caffeine Anhydrous

Caffeine anhydrous is the most common and standard type of caffeine that can be found in almost everything that promises energy, including energy drinks, caffeine pills, coffee, and pre workouts.

It's one of the oldest forms of caffeine. 

Di-Caffeine Malate

Di-caffeine malate is a mix between caffeine and malic acid.

It contains 75% caffeine and 25% malic acid.

The halflife of is increased because of the binding between the two compounds, makgin it last longer and digest slower.

Having a combination of caffeine anhydrous and caffeine malate will help provide a source of fast and slow acting forms of caffeine.

Caffeine Citrate

Caffeine citrate is less seen in pre workouts but it's still found sometimes.

It's a fast acting form of caffeine that is made out of 50% caffeine.

Having a mix of these forms will intensify the experience with different timing of caffeine.
