How Does Inhuman Pyro by AfterDark Supplements Work?

Inhuman Pyro by AfterDark Supplements is a powerful pre-workout intensifier formulated to deliver high-impact energy, focus, and thermogenic activity through a multi-phase ingredient blend. Pyro is designed for experienced users seeking extreme stimulation, mental drive, and performance readiness. It features a delayed-release caffeine matrix, multiple cognitive enhancers, and metabolic support compounds.

The combination of Citrulline, Beta-Alanine, Theobromine, Alpha Yohimbine, and neuroactive agents makes it one of the most aggressive formulas in the AfterDark line—tailored for demanding workouts or stimulant-tolerant users.

It’s a serious pre-workout for advanced users who want strong energy, enhanced alertness, and an intense thermogenic kick.

Supplement Facts
Serving Size: 1 scoop (15g)
Servings Per Container: 21

Ingredient Breakdown


Chromium (as Chromium Nicotinate Glycinate Chelate) – 500mcg
A trace mineral that plays a role in the body’s carbohydrate metabolism. This chelated form may improve bioavailability, and chromium is often used in formulas that support body composition and glucose management.
Vitamin B12 (as Methylcobalamin) – 500mcg
A highly bioactive form of B12 that supports cellular energy production, nervous system health, and red blood cell synthesis. It’s commonly included in stimulant-heavy products to support energy pathways.
Sodium (as Sea Salt) – 120mg
Provides essential electrolytes to maintain fluid balance and muscle function during training.
Chloride (as Sea Salt) – 180mg
Works alongside sodium to support proper hydration and muscle contraction.

Rage and Energy Complex


Delayed Release Caffeine Matrix – 400mg total (Yielding 375mg active caffeine)

  • Caffeine Anhydrous A fast-acting form of caffeine used for immediate mental stimulation and alertness.

  • Dicaffeine Malate A buffered form of caffeine paired with malic acid, offering a slower, sustained release.

  • Micro-Encapsulated Caffeine Caffeine has delayed absorption properties for a longer-lasting, smoother energy curve. This single-source matrix provides rapid onset and extended stimulation with reduced crash effects.


Theobromine HCl – 200mg
A naturally occurring alkaloid found in cocoa. Theobromine offers mild stimulation and may complement caffeine by extending its effects and supporting alertness without excessive stimulation.
NeuroRush™ (Coffea Arabica Extract) – 100mg
A proprietary extract derived from Coffea Arabica beans. This may contain naturally occurring caffeine and polyphenols to support cognitive function and neurosensory effects.
Yohimbine HCl – 3mg
An alkaloid extracted from yohimbe bark. Known for its role in CNS stimulation and thermogenesis, and included in tiny amounts due to potency.
Alpha Yohimbine (Rauwolscine) – 2mg
A more refined, targeted form of yohimbine, often regarded for its effects on mood, alertness, and fat oxidation, and typically used in advanced pre-workouts to enhance intensity.

Inhuman Muscular Volumization & Strength Complex


L-Citrulline – 5000mg
A non-essential amino acid and precursor to nitric oxide. It supports circulation and nutrient delivery during exercise and is a staple in high-performance pump-focused products.
Beta-Alanine – 3500mg
A beta amino acid is involved in carnosine production and is a buffer for muscle acidity. Widely used to support training capacity and muscular endurance.

Advanced Thermogenesis & Pyrotechnics Complex


CapsiBurn™ – 100mg
A proprietary blend of capsicum extracts including Cayenne Pepper (Capsicum annuum), Tabasco Pepper (Capsicum frutescens), and Conjugated Linoleic Acid. Used in formulas targeting thermogenic activity and metabolic stimulation.
CaloriBurn GP™ (Grains of Paradise Extract – 12.5% 6-Paradol) – 25mg
Derived from Aframomum melegueta, this ingredient is standardised for 6-paradol and used in thermogenic blends. Often included in products designed to support body composition goals.
ProGBB® (Gamma-Butyrobetaine) – 25mg
A precursor to L-carnitine, commonly found in thermogenic products. GBB is used in carnitine biosynthesis, which is often associated with energy metabolism and core temperature elevation.

Neural Activation & Anti-Crash Complex


L-Tyrosine (Fermented) – 1000mg
An amino acid that serves as a precursor to dopamine, norepinephrine, and epinephrine. It is used in pre-workouts to support focus and cognitive function under stress.
Choline Bitartrate – 500mg
A choline source supports acetylcholine synthesis, a neurotransmitter essential for neuromuscular control and mental clarity.
Dimethylaminoethanol Bitartrate (DMAE) – 500mg
A compound often included in cognitive formulas, DMAE is associated with supporting mental sharpness and acetylcholine metabolism.
L-Theanine – 35mg
An amino acid found in tea leaves that may smooth out the stimulatory effects of caffeine, helping to maintain calm focus and prevent overstimulation.
Other Ingredients:
Silicon Dioxide, Calcium Silicate, Malic Acid, Citric Acid, Natural & Artificial Flavouring, Sucralose, Acesulfame Potassium, Natural Colours.
Recommended Use
Mix one scoop with 250–300ml of cold water and consume 20–30 minutes before training. Start with half a scoop to assess tolerance. Do not exceed one scoop daily.
It’s unsuitable for beginners or anyone sensitive to yohimbine or high-dose caffeine.
Due to the high stimulant content, avoid taking it close to bedtime.
