The strongest pre workouts reviewed by us do not contain any banned substance

We had our team of body builders and power lifters to try and test various pre workouts which claimed to be powerful pre workout. And after getting feedback from our members we drew the conclusion to the strongest pre workouts. 

Strongest Pre-Workout Supplements 

And that is where pre-workout comes into play. The strongest pre-workouts can cure all this quickly. Most of this which I have recommended pre-workout contains those essential ingredients that help push yourself to work harder and cure muscle fatigue and soreness. I would recommended you should take this pre-workouts 20 to 30 minutes before a workout by dissolving it in water. (1)

These proven and tested ingredients in a pre-workout contain a cure to all the problems while working out and are a great supplement to reach your goals quickly. But there are so many pre-workouts available in the market, and which is the best?

The best and strongest pre-workouts can be classified based on the pre-workout ingredients, the grammage of those ingredients, and your goals. Why are the pre-workout ingredients necessary?

These pre-workout ingredients are the backbone of the pre-workout supplements and can make an excellent pre-workout supplement the strongest.

A strong pre-workout can also be called an intense pre-workout supplement that is highly effective and helps you reach your goals quickly.

Pre-workouts can be divided into stimulant-free pre-workout and high stimulant pre-workouts. Stim-free pre-workouts are pre-workouts that do not contain stimulants like caffeine. Although caffeine is an essential ingredient of many of the best pre-workouts, stim-free pre-workouts can still be just as effective, if not more.

Strongest Pre Workout Supplements

There are also dmha pre-workout varieties. A dmha pre-workout is also referred to as a pre-workout containing Dimethylhexylamine. This is a central nervous system stimulant that helps give the energy to boost performance. These pre-workouts are also considered high stimulant pre-workouts. Though FDA strongly recommends against using them and have made most to withdraw those pre workouts from market. But we haven't recommended any of those in this list. 

Some of the best and strongest pre-workouts have been mentioned below to help you fuel your workouts to get the max performance. 

Top 10 Strongest Pre Workout:

1. Transparent Labs Bulk BLACK Pre Workout (Strongest Pre Workout)

Bulk Black


Form: Powder

Number of Serving: 30

Serving Size: 1 Scoop, 21.2 gms per serving

Diet type: Vegan, gluten-free, major allergen-free

This Transparent Labs Bulk BLACK is an upgraded version of Transparent Lab's Bulk series which anyways is one of the best pre workout we tried out in a very long time, but Bulk BLACK takes it many notch upwards. Most of the strongest pre workout are known to mess with your heart after consumption. But we found none of that with this pre workout. 

The Bulk Black's BlackCherry Flavor which we tried and tested for 30 days, had a great flavor and mixability. 

We ranked it as our best strongest pre workout not just because of its great ingredients list but also the best kick it gave when you are looking to lift heavy or when we did heavy squats. 

Its a perfectly loaded pre workout with all the necessary ingredients for a great strong workout . It gives you that extra push and the third party testing came clean which means its also safe and doesn't contain any kind of banned substance. Not just that what we found was that even in its strongest pre workout ever transparent labs had all its ingredients listed. 

Our trainers and body builders alike enjoyed training with this one. Caffeine Anyhdrous:  The 275mg caffeine is quite strong dose of caffeine for anyone looking for stronger stimulant. But at the same time we found that post workout we didnt find any anxious feelings. And could take this pre workout in the evening, workout and still get a sound sleep at night.

2. Strongest Stimulant Pre Workout: 

Pre Kaged Elite

Pre Kaged Elite


Form: Powder

Number of Servings: 20 scoops

Serving Size: 35.3 g per scoop

Flavors: Seven different flavors

Diet type: Vegan, gluten-free, major allergen-free

A well-known name in the industry of pre-workouts, Kaged has recently introduced their new and innovative formula: Kaged Elite -a high stim pre-workout. The main focus behind this complete pre-workout formula is to enhance strength, energy, and muscle endurance.

The company has packed Kaged Elite pre-workout with healthy and clean ingredients that are scientifically proven and have undergone third-party testing to ensure that there are no banned substances. This pre-workout will give you an elite experience- as the name suggests. 

Pre Kaged Elite has much bigger scoop at 35-gram per serving than the Pre Kaged. A Scoop of Kaged Elite pre-workout is filled with 10 grams of L-citrulline, 388 mg of caffeine (purely natural), 3.2 grams of Beta-alanine, 3 grams of creatine monohydrate and creatine HCl, and 2 grams of creatine nitrate. This makes the pre-workout strong.

Your intra workout is also covered with Pre Kaged Elite, so you don't need to take separate intra workout.

Pre Kaged Elite Scoop Size

L-citrulline helps by increasing blood flow, which increases oxygen flow to the muscles and hence the respiration rate (2). It increases the amount of energy and boosts physical and mental performance - the main reason for a pre-workout. Caffeine anhydrous in pre-workouts helps in improving the overall focus. Beta-alanine is the OG endurance booster. Beta-alanine helps produce carnosine (3), which buffers the lactic acid produced during exercise. It decreases the pain felt after an intense workout and increases muscular endurance.

Creatine monohydrate is added as CreacCear. It is a version of the same amino acid found in many pre-workouts but covered with milk protein. So what does it do? It increases the overall time of digestion (while solving the gut issues faced by many users of creatine monohydrate). Creatine increases the production of ATP, the cell's energy powerhouse, increasing the energy available. 

Pre Laged Elite Straberry Lemonade flavor

Creatine nitrate is an innovative way to increase the amount of creatine HCl per dose, which increases the performance and, at the same time, works great with L-citrulline for better performance—making this pre-workout much better.
