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.

Silicon Dioxide, Calcium Silicate, Malic Acid, Citric Acid, Natural & Artificial Flavouring, Sucralose, Acesulfame Potassium, Natural Colours.


Our Observations and Customer Feedback

Inhuman Pyro delivers a multi-stage stimulant experience with fast-acting and long-lasting caffeine sources stacked with neuro stimulants like Yohimbine, Theobromine, and DMAE. It’s a serious pre-workout for advanced users who want strong energy, enhanced alertness, and an intense thermogenic kick.

It’s unsuitable for beginners or anyone sensitive to yohimbine or high-dose caffeine.


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. Due to the high stimulant content, avoid taking it close to bedtime.
