10g Citrulline. 400mg Caffeine. Hardcore full-label intensity.
Dark Labs Maniaco is a fully disclosed, high-stim pre-workout that nails two big goals: delivering a real pump with a huge 10g dose of citrulline, and backing it with a serious stim stack for folks who know their way around stimulants. This isn't your everyday pre—it's for those brutal sessions, with solid performance ingredients up front and a hardcore stim vibe on top.
It starts with 10,000mg L-citrulline, which is a standout amount. Citrulline boosts plasma arginine better than taking arginine straight because it skips a lot of breakdown in your gut and liver before turning into arginine in the kidneys. Arginine is key for making nitric oxide, which widens blood vessels, improves blood flow, gets nutrients to muscles, and gives that awesome pump. Studies show citrulline works well for this, with doses usually around 3-8g. Maniaco cranks it to 10g, way above the typical 3-6g you see in most pre-workouts.
There's 4,000mg L-tyrosine, a big dose for a pre-workout. Tyrosine is the building block for brain chemicals like dopamine and norepinephrine. When you're stressed, tired, or training hard, extra tyrosine can help keep your focus and mental game strong. Results vary, but it fits here since caffeine and DMHA ramp up those brain chemicals—tyrosine helps meet the demand.
Beta-alanine is at 3,200mg, the standard dose backed by research for building carnosine in muscles over time. Carnosine helps neutralize acid buildup during intense reps, which is why beta-alanine is less

Key Highlights
- 10,000mg L-Citrulline — this is a seriously high dose, way past the 3-6g where a lot of pre-workouts quit. It feeds into the arginine-nitric oxide path, opening up blood vessels for better flow, a bigger pump, and more endurance in your sets.
- 4,000mg L-Tyrosine — a hefty amount that backs up brain chemical production when things get tough. Basically, it helps you stay focused and steady when the stims are cranking.
- 3,200mg Beta-Alanine — the go-to daily dose for loading up carnosine in muscles. That's key for handling acid buildup in high-intensity work, so you can push through the burn without cutting sets short.
- 400mg Caffeine Anhydrous — a strong caffeine hit that wakes you up fast. You'll feel more alert, energized, and ready to crush it compared to those 200-300mg options.
- 300mg 2-Aminoisoheptane (DMHA) — a tough stim for folks who know their stuff. It amps up your drive and urgency, making this way more intense than just caffeine alone.
- 300mg N-Phenethyldimethylamine Citrate — this adds to that feel-good, locked-in vibe. In the gym, it helps with the mood boost and sharp focus that serious lifters love.
- 2mg Rauwolfia Vomitoria Extract standardized to minimum 90% alpha yohimbine — small but powerful. It sharpens your energy, heats things up, and ramps the stim feel.
- Pump and stims together — lots of hardcore pre-workouts go all-in on stims and forget the pump. Maniaco fixes that with a solid 10g citrulline base to avoid that flat, squeezed-out feeling from heavy stims.

Who Is This For?
- Pro bodybuilders in hypertrophy phases who need more than just a buzz. The 10g citrulline delivers that full pump for better feel and connection, while 400mg caffeine plus DMHA and Eria-style stims bring the heat for long grinds.
- Seasoned lifters training early who want quick activation. Caffeine hits fast, tyrosine backs brain output under pressure, and the stim stack is for those who tolerate it well.
- Strength folks on heavy lower or compound days needing drive, focus, and set recovery. 3.2g beta-alanine helps with acid buffering long-term, stims keep you aggressive through mains and extras.
- High-tolerance users bored by 200-300mg caffeine pre-workouts. Maniaco is for those ready for a transparent, hard-hitting formula with real mental punch.
- Lifters who won't pick between pump and stims. Hardcore options often overload stims and ignore nitric oxide; this one balances with 10g citrulline to keep feel alive.
- Athletes in high-volume workouts with quick rests where fatigue hits fast. The 3.2g beta-alanine is the daily dose for carnosine, great for repeats, giants, and finishers.
How to Use
Try half a scoop first to check tolerance, especially if you're new to high-stim stuff with DMHA and alpha yohimbine. Full scoop is for folks who handle 400mg caffeine well. Take it 20-30 minutes pre-workout; that lets caffeine and stims build during warm-ups, with citrulline ready for the real work. Mix in 10-16 oz cold water and shake it good. Empty stomach means faster kick, food slows it down. Skip stacking with other stims, fat burners, nootropics, or extra caffeine—this is already intense. Add creatine monohydrate since it's not in here; electrolytes help pump too. Cycle it if tolerance builds—lots of pros save it for big days. Store it cool and dry, keep it sealed.
What to Expect
Minutes 0-10: after mixing and downing it, things start subtle, especially post-meal, but pros feel it ramping fast. Minutes 10-20: caffeine kicks in, beta-alanine might tingle, and you get more alert and ready. Minutes 20-40: peak time for most, with stims hitting hard and citrulline pump showing as you train. Minutes 40-90: energy stays up, focus lingers, depending on your tolerance and how long you go. Days 1-7: instant wins are energy, focus, and pump, while beta-alanine is just starting. Weeks 2-4: beta-alanine steps up as carnosine builds, making high-burn sets easier.

Frequently Asked Questions
How much caffeine is in Dark Labs Maniaco?
Each full scoop delivers 400mg of caffeine anhydrous. That is a high dose on its own, and Maniaco also includes 300mg DMHA, 300mg N-phenethyldimethylamine citrate, and alpha yohimbine, so the total stimulant experience is much more intense than a standard 400mg caffeine-only pre-workout.
Is Dark Labs Maniaco a beginner pre-workout?
No. The combination of 400mg caffeine, 300mg DMHA, 300mg N-phenethyldimethylamine citrate, and alpha yohimbine makes this an advanced-user formula designed for people with established stimulant tolerance.
What makes Maniaco different from most high-stim pre-workouts?
The biggest difference is that Maniaco still commits to performance dosing on the pump side. It gives you 10g L-citrulline and 3.2g beta-alanine instead of relying only on stimulants, which helps preserve blood flow and repeated-effort support alongside the aggressive CNS hit.
What does the 10g of L-citrulline actually do?
L-citrulline converts to arginine in the body and supports nitric oxide production, which promotes vasodilation and blood flow. In the gym, that translates to better pump, improved muscle fullness, and a less flat training feel than many stim-heavy formulas create.
Why is there 4g of L-tyrosine in Maniaco?
L-tyrosine is the amino acid precursor for catecholamines like dopamine and norepinephrine. At 4g, it is included to support focus, stress resilience, and mental output in a formula that places heavy demand on stimulant-related neurotransmitter systems.
Will Maniaco make me tingle?
Very likely. The formula contains 3.2g beta-alanine, which commonly causes a harmless tingling sensation called paresthesia, especially when taken on an emptier stomach.
Should I start with a full scoop?
Only if you already know you tolerate very high-stim pre-workouts well. Most users should start with half a scoop because the combination of caffeine, DMHA, and alpha yohimbine can feel dramatically stronger than the label’s caffeine number alone suggests.
Can I stack Maniaco with a fat burner or energy drink?
That is not advisable. Maniaco already contains an aggressive stimulant profile, and adding more caffeine or additional stimulants can significantly increase the risk of jitters, rapid heart rate, elevated blood pressure, and a generally excessive experience.
Does Maniaco need to be cycled?
Cycling is not mandatory in a strict sense, but it is smart. Because stimulant tolerance can build over time, many experienced users reserve formulas like this for their hardest training days rather than using them before every single session.
What should I stack with Maniaco for a more complete performance setup?
A standalone creatine monohydrate product is the most obvious addition because Maniaco does not include creatine. Daily creatine supports phosphocreatine regeneration for strength and power, complementing Maniaco’s citrulline-driven pump, beta-alanine endurance support, and stimulant-fueled training intensity.
