5g citrulline, 3.5g beta-alanine, 375mg caffeine, real thermogenesis.
Afterdark Inhuman Pyro is a real thermo pre-workout. It's not your basic pre with a dash of hot extracts. The idea here is clear: hit you with strong stims, solid training support, and thermo action from multiple angles—all in one scoop. That's key because a lot of fat-burning pres focus too much on energy and skimp on actual gym help. This one keeps performance at the core with 5,000mg L-citrulline and 3,500mg beta-alanine leading the way.
5g L-citrulline is a solid dose that fits right in the 3-8g range from studies. Citrulline turns into arginine in your kidneys better than taking arginine straight, which helps make nitric oxide. That means wider blood vessels, better pumps, and more blood to your muscles during sets. You'll feel it in the gym. 3.5g beta-alanine hits the key 3.2g daily mark for building carnosine in muscles. Carnosine buffers acid buildup during tough reps. So you get better output on repeats and a bit more staying power when the burn kicks in.
The stim setup is intense. Total caffeine hits 375mg from a mix of caffeine anhydrous, dicaffeine malate, and micro-encapsulated caffeine. That's a big dose no matter how you slice it. Anhydrous gives quick kick, dicaffeine malate stretches it out, and micro-encapsulation keeps energy going longer. 200mg theobromine HCl adds a smoother, longer stim vibe—feels more uplifting and less harsh than caffeine by itself. NeuroRush™ at 100mg from Coffea arabica fruit extract layers in some focus from coffee fruit, helping energy feel steady and sharp.

Key Highlights
- 5,000mg L-Citrulline — this is a strong dose that lands right in the 3-8g range from research. Citrulline boosts arginine levels better than taking arginine directly, which pumps up nitric oxide for better blood flow, fuller pumps, and stronger workouts.
- 3,500mg Beta-Alanine — it beats the usual 3.2g daily level for loading carnosine in muscles. Beta-alanine isn't about instant buzz; it's about building up your ability to fight fatigue so tough sets and repeats feel easier over time.
- 375mg Total Caffeine — this is legit high-stim territory, not some mild pre in disguise. It's at the top end for performance boosts and made for folks who want serious energy, drive, and workouts that stay fired up.
- Three-Source Caffeine Delivery — caffeine anhydrous, dicaffeine malate, and micro-encapsulated caffeine build a timed release. No quick spike and drop; it hits fast, holds steady, and keeps you going deeper into your session.
- 200mg Theobromine HCl — adds another stim layer to make the energy feel broader than just caffeine. Lots of people say theobromine feels smoother and lasts longer, making the whole thing less one-note.
- 3mg Yohimbine HCl + 2mg Alpha Yohimbine — this duo brings real thermo punch. Doses like this are what experienced users feel, adding urgency, warmth, hunger control, and that edge that makes cutting pres stand out from basic energy drinks.
- 100mg CapsiBurn™ — a branded pepper extract setup aimed at heat and metabolism without the rough gut feel. It's about firing up thermo effects while keeping things comfortable.
- 25mg CaloriBurn GP™ — grains of paradise extract with 12.5% 6-paradol to boost thermogenesis via brown fat pathways. Smart pick for fat loss since it hits different from caffeine or yohimbine.

Who Is This For?
- Physique folks cutting calories who need a pre to keep workouts intense. 375mg caffeine matrix, yohimbine duo, and thermo trio bring energy and heat, while 5g citrulline and 3.5g beta-alanine hold pumps and output as cals drop.
- High-stim vets who get nothing from 200mg caffeine pres. Built for those who know their tolerance and want layered energy plus yohimbine HCl and alpha yohimbine's edge.
- Bodybuilders in high-volume phases wanting aggression and flow. L-citrulline delivers pumps and nutrients, beta-alanine sustains reps as burn builds.
- Morning lifters doing fasted cuts. Yohimbine fits that spot, and this adds strong stims plus thermos for warmth, sweat, and drive.
- Cross-trainers in conditioning who need repeat output and drive. Beta-alanine's dose builds carnosine, caffeine-tyrosine combo suits intervals.
- Lifters tired of spike-crash from basic caffeine. Anhydrous, dicaffeine malate, and micro-encapsulated mix extends the curve for deeper session support.
How to Use
Mix 1 scoop in 10-14 oz cold water 20-30 minutes pre-workout. If you're new or not big on high stims, start with half—the full hit has 375mg caffeine, yohimbine HCl, alpha yohimbine, and 200mg theobromine. Use a shaker for best mix, as it's a 15g scoop and stirring might leave clumps. Empty stomach speeds onset and thermo feel, but if stims bug your gut, eat light 60-90 minutes before. Don't mix with coffee, energy stuff, nootropics, or burners unless tracking intake. Stacks great with creatine monohydrate and intra hydration, since creatine boosts intensity and thermos increase sweat. Use on training days for beta-alanine buildup. If using daily long-term, take a short caffeine break every few weeks to reset tolerance. Keep it sealed in a cool, dry spot for freshness.
What to Expect
0-10 minutes: stimulation starts building, especially on an empty stomach. 10-20 minutes: caffeine kicks in, beta-alanine tingles show, and thermos bring a warm feel. 20-40 minutes: peak time for training with sharp focus, drive, and citrulline pumps shining. 40-90 minutes: layered caffeine keeps it going without crashing, thanks to theobromine and slow-release parts. Days 1-7: you feel stims, heat, and pumps strong, while beta-alanine loads up. Weeks 2-4: beta-alanine shines with higher carnosine, making high-rep and conditioning work easier under fatigue. Over time, it goes from intense to supporting real repeat gains.

Frequently Asked Questions
How much caffeine is in Afterdark Inhuman Pyro per serving?
A full 1-scoop serving delivers 375mg total caffeine from a delayed-release matrix of caffeine anhydrous, dicaffeine malate, and micro-encapsulated caffeine. That is a high-stim dose intended for experienced users, not beginners.
Is Inhuman Pyro a fat burner or a pre-workout?
It is both, but the better classification is a thermogenic pre-workout. It combines real training ingredients like 5g L-citrulline and 3.5g beta-alanine with a dedicated fat-loss-oriented stack featuring yohimbine HCl, alpha yohimbine, CapsiBurn™, CaloriBurn GP™, and ProGBB™.
Should I start with a full scoop?
No, not unless you already have a proven tolerance to aggressive stimulant formulas. Start with half a scoop first because 375mg caffeine plus yohimbine alkaloids and 200mg theobromine can feel much stronger than a standard pre-workout.
What does the 5g of L-citrulline actually do in this formula?
L-citrulline supports nitric oxide production by raising arginine levels more effectively than oral arginine itself. In practical gym terms, that means better blood flow, a fuller pump, and improved delivery of oxygen and nutrients to working muscle.
Is 3.5g beta-alanine enough to matter?
Yes. The standard research-backed daily intake for beta-alanine loading is around 3.2g, and this formula provides 3.5g per serving. The main benefit is not instant strength but improved carnosine saturation over time, which helps buffer fatigue during hard efforts.
Why does this formula include both yohimbine HCl and alpha yohimbine?
They are used together to create a stronger adrenergic and thermogenic effect than caffeine alone. For experienced users, that usually means more urgency, more heat, more sweat, and often stronger appetite suppression, but it also increases the chance of jitters or anxiousness if tolerance is low.
Can I stack Inhuman Pyro with another fat burner?
Most users should not. This formula already contains high caffeine, yohimbine HCl, alpha yohimbine, theobromine, and multiple thermogenic ingredients, so adding another burner can push stimulant load too high.
What should I stack with Inhuman Pyro for better results?
A standalone creatine monohydrate is the cleanest addition because this formula does not include creatine. Creatine supports ATP regeneration and strength performance, which pairs well with beta-alanine's fatigue-buffering role and citrulline's blood-flow support.
Will this make me sweat more than a normal pre-workout?
Very likely, yes. ProGBB™, CapsiBurn™, CaloriBurn GP™, caffeine, and the yohimbine pair are all there to increase the thermogenic feel of the product, and many users notice a clear rise in body heat and perspiration.
Is the label fully transparent?
Not completely. Many key ingredients and doses are disclosed, including the 375mg total caffeine yield, 5g citrulline, and 3.5g beta-alanine, but some ingredients are still grouped into proprietary complexes, so the exact split between individual caffeine sources is not shown.
