The Best Hardcore Boosters 2024
The year is flying by, and with it, the market for the most powerful pre-workouts based on real hardcore stimulants is fluctuating. BOOSTERJUNKIES.DE ranks the best hardcore boosters of the early 2020s for you!
DMAA, DMBA, Eria Jarensis, AMP, and the list goes on – the lineup of commonly used amines and derivatives, in short, stimulants that deliver effectiveness, tunnel vision, monster focus, and hardcore sessions at the gym, keeps getting longer.
At BOOSTERJUNKIES.DE, we never tire of testing them all.
And, as usual, we did it again at the start of this year: we’ve compiled our UPDATED list of the most current and newly released hardcore training boosters based on their effects, price-performance ratio, taste, and packaging design.
We do not claim to be comprehensive or entirely objective. While it is our best and most honorable intention to highlight only the most potent and highest-quality boosters and rank them accordingly, we want to point out one thing:
The effects of a pre-workout vary greatly from athlete to athlete. They are based solely on subjective and individually experienced physical impressions.
As a team of academically trained and practically experienced athletes, our goal is to provide you with trends and to represent our own impressions, as well as those of customers and friends, in a realistic and representative way. We take into account the promises and marketing slogans of the companies and products we present, comparing them with expectations and, ultimately, with actual experiences.
Where analyses or background information are available, we provide insights into ingredients and effects, though we cannot always guarantee the authenticity of the substances listed.
However, we generally rely only on products that are reputable, work and appear to be of high quality, and come from credible and trustworthy sources.
Up next is the Top 10 of the best hardcore boosters of 2024 so far.
NOTE: The following training boosters are extremely potent and should not be underestimated in their effects. Please inform yourself about the correct dosage and tolerability before use. The following boosters are not suitable for teenagers or beginners!

#10: Blackstone Labs – Dust X
The brand Blackstone Labs, founded by PJ Braun, has become a well-established name in the hardcore supplements sector, whether it’s prohormones, SARMs, or training boosters. The Dust X continues to deliver brutally strong performance and is the highest-dosed and most powerful booster from the brand. It promises long-lasting energy and, for a hardcore booster, a really good muscle pump. The latter is supported by 4 grams of Citrulline Malate and 1 gram of Agmatine Sulfate per serving. In addition to the "main star" of the show with a hefty 150 mg of DMHA per serving, Dust X stands out with a huge dose of psychoactive nootropics (Dimethylaminoethanol, Phenylethylamine, L-Tyrosine, and Huperzine A) that provide a first-class focus. All of this combined earns it a deserved spot in our Top-10. Pro tip: Of the 6 flavors, Sour Gummy Bear is highly recommended.

#9 Modern Hardcore – Arez Titanium
The legend is back! After Modern Hardcore secured the rights to the AREZ boosters, the manufacturer released its own version, which immediately sparked excitement for us. This is mainly due to the almost unchanged formula. The pump is again provided by 3000 mg of L-Citrulline and 500 mg of Agmatine Sulfate per serving. To combat muscle fatigue, 3200 mg of Beta-Alanine is included. Booster fans who enjoy the typical tingling sensation of Beta-Alanine (Beta-Tingle) will love this. With 250 mg of Choline Bitartrate, your mental fitness and cognitive performance are also taken care of. Of course, there are plenty of hardcore stimulants, such as 175 mg of Juglans Regia Extract (better known as DMHA), 75 mg of Eria Jarensis Extract, 30 mg of Synephrine, and 10 mg of Hordenine in this version. For the necessary energy boost, 300 mg of caffeine and 200 mg of B-Phenylethylamine are included. A solid 2.5 mg of Alpha Yohimbine adds an extra dose of motivation and drive. In short, this new edition is once again highly impressive.
Product Features:
- Almost unchanged formula from the original
- 2,5 mg Alpha-Yohimbine
- Delicious flavors
Product rating "Good"
#8 Insane Labz – Psychotic
Insane Labz has now released several variants of its Psychotic series. In our opinion, however, nothing beats the "original" Psychotic. The core of the 4459 mg Proprietary Blend (yes, we’re not a fan of proprietary blends, but the effect speaks for itself) is Insane Labz’s patented ingredient "AMPiberry" (officially juniper berry extract, but honestly: there’s something else in here ). The base is formed by Beta-Alanine, Creatine, and Caffeine. To enhance cognitive performance, there’s Dimethylaminoethanol (DMAE), Hordenine, and Huperzine Serrata. Alpha Yohimbine, in turn, will have you sweating. This is a "classic" hardcore booster that shines particularly in energy, endurance, and focus. Unfortunately, it falls short in the pump department, which is no surprise considering the label.
Product Features:
- Patented ingredient AMPiberry
- With Alpha-Yohimbine
- Best value

#7 Condemned Labz – Convict Stim
Long considered a true insider tip and still not easily available, the guys from Condemned Labz in the UK have released a hardcore booster that boasts a solid 225 mg of 2-Aminoisoheptane (DMHA) and 50 mg of Higenamine. Additionally, 15 mg of Paradoxine Grains of Paradise and 3 mg of Yohimbine HCL give your fat burning a real boost, without spiking your heart rate too much. For muscle pump, it contains 4000 mg of pure L-Citrulline.

#6 APS Mesomorph V4
Mesomorph in version V4 prominently advertises with the slogan "Fueled by Geranium Extract" – which is nothing other than DMAA. This marks Mesomorph’s return to the roots of its successful original version. Like previous versions, V4 also features a proprietary blend, or rather three of them, with the "Neuromorph-Energized Stimulant Matrix" at 1860 mg being the most interesting for stim junkies. This includes ingredients such as Methylxanthine Anhydrous, which acts similarly to caffeine by expanding the bronchi, 2-Aminoisoheptane (DMHA), and Geranium Extract (DMAA). Mesomorph V4 contains a wide variety of ingredients, all packed into a hefty serving size of 15.5 grams. The booster provides a balanced effect and performs well in all categories without making you feel overly stimulated – the effect is relatively "smooth" and not overpowering.
Product Features:
- Close to the original version
- With Geranium Extract
- Delicious flavors

#5 ABL Pharma – Phenta Plex
ABL Pharma has created a hardcore booster with Phenta Plex that delivers high energy levels and razor-sharp focus. This is achieved through a combination of 400mg Caffeine Anhydrous, 100mg Synephrine, 100mg Eleuthero Root Extract, and 100mg DMHA. These four ingredients are designed to provide an intense focus. The formula is completed with a 5,550mg proprietary blend, which includes Agmatine Sulfate, Hordenine HCL, Beta-Alanine, and Taurine. Despite the stimulants and the accompanying energy boost, there is no crash! ABL Pharma delivers exactly what they promise on the label. Additionally, Phenta Plex also works well as a brain booster, providing a significant performance increase in concentration and cognitive ability during mentally demanding tasks.
Product Features:
- Strong energy boost and long-lasting effect

Additionally, the other blends like "5 Star Nootropics," "Quadro Anti-Crash & Defence," "Thermo Blend," and "Quadro Pump & Vascularity" are packed with powerful ingredients.

#3 Psycho Pharma – Edge of Insanity
The booster from the guys at Psycho Pharma advertises with a feeling like being on "Kush" (a strain of cannabis), and the Edge of Insanity can indeed drive you to the "edge of madness" . Particularly the hefty 4 mg of Alpha Yohimbine is nothing to take lightly and isn’t for the faint-hearted. Expect cold sweats and an increased heart rate. Along with the 4 mg Alpha Yo, there are also 5 mg of Yohimbine HCL. The energy base is provided by 350 mg of caffeine, 20 mg of theobromine, and 75 mg of Infinergy.
To combat training stress and promote mental relaxation and balance, the included 1000 mg of Gamma Aminobutyric Acid (GABA) come into play. For a strong pump, you’ll benefit from a hefty 8000 mg of Citrulline Malate, while 3200 mg of Beta Alanine helps to reduce muscle fatigue.
Product Features:
- Two forms of caffeine for a time-released effect
- A solid 4 mg of Alpha-Yohimbine + 5 mg Yohimbine HCL
- Delicious flavors

#2 Devil’s Pharma – Devil’s Work
The Devil’s Work from Devil’s Pharma is a true all-rounder in the world of hardcore boosters. With a hefty serving size of 12 grams, it combines all the ingredients necessary to deliver energy, drive, focus, and pump in equal measure. The pump is supported by a symbiosis of Citrulline Malate, AAKG, AGmass, Glycerol, and Norvaline— a pump matrix that is rarely found in the hardcore booster segment and delivers long-lasting, swelling, and vascular results.
The use of nootropics such as Mucuna Pruriens (40mg) is also noteworthy, as it stimulates the dopaminergic system. Of course, they didn’t skimp on the "classic" hardcore stimulants either. The list of ingredients is long and impresses with a clever combination and dosing of each component. The 250 mg of DMDH immediately catches the eye of any hardcore booster enthusiast, but 50 mg of Synephrine HCL, 45 mg of Hordenine, 15 mg of Higenamine, and 2 mg of Yohimbine HCL are also worth a close look and practically scream to be tested. Last but not least, the brand shines with a professional layout down to the last detail, even going so far as to differentiate itself from the competition with clever names for its flavors (Monstrous Mango, Tweaked Tangerine Claw, Devil’s Candy)—with resounding success!
Product Features:
- A true hardcore booster all-rounder
- 250 mg DMHA
- Combines energy, drive, focus, and pump equally

#1 KJ Labs Smash AMF
This is a true underground booster. Accordingly, there is no website for the manufacturer KJ Labs, and there is little information available online. A quick look at the design of the container and its label may leave you puzzled. The design looks like early attempts with Microsoft Paint, and the formulation and dosages don’t always seem to make sense. But don’t be deceived: this booster hits hard, especially delivering a razor-sharp focus during and even after training. Additionally, it strongly suppresses your appetite post-workout. We can’t pinpoint exactly where these effects come from. Judging by the label, the impact should be much milder. On paper, it only contains 350 mg of caffeine, 50 mg of synephrine, 2.5 mg of Yohimbine HCL, along with endurance and pump ingredients like citrulline, beta-alanine, creatine HCL, and taurine. However, we can confidently say the Smash AMF feels much more intense than the label suggests. If you enjoy training in a focused "tunnel" state, need a stable energy boost, and are on a diet, this product won’t disappoint. However, it’s not for beginners, and you should be aware that you’re dealing with absolute underground goods here.
Product Features:
- Strong energy level
- Razor-sharp focus
- Hunger sensation is significantly suppressed
