Crack OG by Dark Labs has quickly become one of my top pre-workout choices this year.
The real game-changer in Crack OG is its stimulant blend.
It's the combination of caffeine, DMHA, Eria Jarensis, and Alpha Yohimbine that delivers that high-energy kick I need for my workouts.
I don't know what it is, but it seems to be one of the highest quality, hardest hitting formula's I've had so far.
This isn't just a burst of energy; it's sustained and focused, but yet super intense. Perfect for those long, intense sessions.
Crack OG delivers unparalleled energy with 400mg of caffeine and a potent stimulant blend.
However, as Matt Rogers, Registered Dietitian at Tropical Oasis, advises, high-stimulant pre-workouts should not be used daily due to the risk of reliance and potential impacts on heart health. Save these for your most demanding workout sessions
The nitric oxide boosters like L-Citrulline, Beta-Alanine, Agmatine, and Arginine HCL complement the stimulants well.
They don't directly contribute to the energy surge, but they enhance my overall workout performance.
This synergy between the stimulants and nitric oxide boosters makes Crack OG stand out.
Training on an empty stomach can be tough, but Crack OG has changed that for me.
It's my go-to, especially for fasted training.
The energy it provides makes these sessions feel less daunting and more productive.
I can push harder and get the most out of every workout.
The mental focus that comes with Crack OG is another major plus.
It's not just about being alert; it's about being completely in tune with my workout.
This concentration level helps me maximize my intensity and efforts.
But what makes Crack OG a favorite is the euphoria.
It's an incredible feeling that turns every workout into an enjoyable experience.
Crack OG by Dark Labs is more than just a pre-workout.
It's a powerful tool that enhances both my physical performance and mental focus.
It's particularly effective for those challenging fasted workouts.

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.

Instead, El Jefe relies on a scientifically backed blend of stimulants like Eria Jarensis, Theobromine, and various forms of Caffeine to deliver an experience that can only be described as hard-hitting.
Check out this comprehensive El Jefe review for a more in-depth look at this powerhouse.
The potency of this pre-workout is such that even seasoned gym-goers might want to think twice before going for a full serving.
It's not just about the stimulant kick; the formula also includes a generous 8g of Citrulline and 4g of Beta-Alanine, aimed at enhancing blood flow and buffering muscle fatigue, respectively.

In a market saturated with pre-workouts that often rely on flashy marketing and unproven ingredients, El Jefe stands as a beacon of effectiveness and quality.
It's a pre-workout that delivers high stimulant levels without resorting to exotic or potentially risky ingredients.

Kill Switch has quickly earned its place among the strongest pre-workouts, comparable to infamous names like Excelsior and Craze.
It’s not just the listed stimulants like 115mg of DMAA or 300mg of caffeine, it’s the unrelenting energy, tunnel-vision focus, and appetite suppression that make it feel truly "special."
From the first scoop, Kill Switch delivers:
What sets Kill Switch apart is how it feels beyond the label. Many users, myself included, speculate there may be "something extra" in the formula. It feels smoother yet more potent than traditional DMAA pre-workouts, with effects that linger far beyond the gym.
If you’ve tried Excelsior or Craze, you’ll know what to expect—a pre-workout that doesn’t just give energy but transforms your entire workout experience. Kill Switch feels like a worthy successor, delivering similar "spiked" effects with its own unique twist.
Usage: Mix one scoop with 8-12 oz of water and consume 30 minutes before your workout.

Crack Gold by Dark Labs has been making a name for itself as one of the most sought-after, potent pre-workouts on the market.
It has become a hot commodity, often selling out as soon as it's restocked.
What sets it apart is its unique combination of DMAA and DMHA, making it a tried and true favorite among those who prefer pre-workouts with exotic stimulants. Designed with advanced users in mind, even they find it quite intense.

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.

The strongest pre-workouts provide exceptional energy and focus but should be used wisely to avoid tolerance and side effects.
Remember to cycle stimulants, consider basic supplements, and adjust dosages to your tolerance and needs.
While these pre-workouts provide the energy and focus to help you push your limits, it’s critical to use them responsibly.
Matt Rogers suggests reserving high-stimulant products for tough workouts to avoid reliance, while Clytie Robinette advises cycling your usage to minimize side effects and keep your body responsive to these potent formulas
