El Jefe by Xtremis Cartel is not just another face in the crowd; it's a pre-workout that commands respect, especially among those seeking high-stimulant options.

It's incredibly energizing, providing a powerful stimulant jolt without being overwhelming.

Excelsior has been one of the harder pre workouts to find due to it's supply shortage.
This has been the strongest pre workouts over the past few years but recently it's been hard to recommend because of it's shortage.
Update November 2021 - feb 2023: It's been nearly a year since Excelsior hasn't been available in the U.S. It's time to consider the alternatives. Check out Gulag, a mood enhancing pre workout.
I can also recommend Wild Fire instead as it feels very strong but still very clean.
Or check out the list of where to buy banned pre-workouts.
But meanwhile, we have found something comparable, and maybe even better because it's half the price of Excelsior: check out Phenta Plex.
With Phenta Plex, you'll get crazy strong energy and focus for more than 10 hours at a time.
Or check out Power by Badass Labz, which feels much stronger than an actual pre-workout with DMHA and caffeine.
Excelsior can also be found in the UK but it's nearly $100...
Back to Excelsior...
This along with Craze (from Driven Sports) will go down as some of the most controversial pre-workouts to exist.
Excelsior has the same focus and energy that the original Craze had.
No, we're not referring to the reformulated versions like Craze V2, or CRZ OG.
We're talking about the original Craze from 2010. The OG.
Excelsior has a similar euphoric feel as the original Craze once had.
The same build-up of energy, the same happy “feels” and you won't want to leave the gym.
The energy lasts for hours.
People report they can't sleep if they take it after 3 pm (again similar to what Craze users reported).
I personally can't sleep until 3 am if I take it after 12 pm.
While it has DMHA and a few other ingredients, it is nothing like any other product that has similar ingredients.
And the appetite suppression is incredibly strong.
Pizza will no longer be appealing, and forget the craving for junk food.
You'll probably forget to eat.
There's definitely something more than the ingredient label shows.
The feeling is sort of like an amphetamine type feel, with a ton of focus and a speedy feeling to it.
There's a bit of a mood uplift, but there's also a crash after a few hours.
I wouldn't take this more than once a month because honestly it's strong in effects and I don't think it's worth risking my well-being
Expect to pay around 50 (or about 60-70 if you're outside the US)
That's around $1.5 per serving.
It's worth it for some feel-good energy and motivation.
But if you're prone to depression, you may want to look for another pre-workout because once you've used a lot of Excelsior, you'll be going through some nasty withdrawals.
This is why you should limit usage or not use it at all if you know you can't help it.
It's available worldwide, throughout the UK and the US.
Try Excelsior and look no further, before you find this Craze replacement gone.
(If you're from the UK or live near it, check it out in this UK store)
If you're prone to depression, I recommend trying something else as this may have a strong crash after a few hours.
This is only for experienced users who know what they are doing.
If you're ordering this in April 2021 and beyond, you're getting a fresh batch.
It may be the same exact feeling or it may be altered in a way.
To recap, here are the strongest pre-workouts we've reviewed:
These pre-workouts contain above-average levels of stimulants, delivering high energy and powerful performance boosts.
