David vs. Goliath Ingredient Breakdown

L-Citrulline – 8,000 mg

At 8 grams per serving, L-citrulline represents the primary pump-oriented component of David vs. Goliath.

L-citrulline participates in the urea cycle and can increase circulating L-arginine availability. Arginine subsequently serves as a substrate for nitric oxide synthase, contributing to nitric oxide production and vascular signaling.

For resistance-training formulas, this makes L-citrulline particularly relevant for supporting:

• Nitric oxide production

• Exercise-associated blood flow

• Muscle pumps

• Training vascularity

• High-volume resistance training

An 8,000 mg dose also makes citrulline a major component of the formula rather than a token addition to an otherwise stimulant-dominant product.

Beta-Alanine – 4,500 mg

David vs. Goliath provides 4,500 mg of beta-alanine per serving.

Beta-alanine is the rate-limiting precursor involved in intramuscular carnosine synthesis. Carnosine contributes to buffering hydrogen ions generated during high-intensity muscular activity.

Beta-alanine is therefore commonly incorporated into performance formulas designed around repeated high-intensity muscular contractions and demanding training sessions.

The familiar temporary tingling or prickling sensation associated with beta-alanine is known as paresthesia and can become more noticeable with larger single doses.

Choline Bitartrate – 600 mg

The formula contains 600 mg of choline bitartrate, providing 246 mg of choline according to the Supplement Facts panel.

Choline is an essential nutrient and precursor to the neurotransmitter acetylcholine.

Acetylcholine is involved in:

• Cholinergic neurotransmission

• Attention

• Neuromuscular signaling

• Motor control

• Cognitive processes

Its presence fits the formula's focus-oriented design, particularly alongside Huperzine A.

Caffeine Anhydrous – 400 mg

Each serving contains 400 mg of caffeine anhydrous, immediately placing David vs. Goliath within the high-stimulant category.

Caffeine primarily functions as an adenosine receptor antagonist. Reducing adenosine signaling contributes to caffeine's characteristic effects on wakefulness, perceived energy, alertness, and exercise performance.

The 400 mg listed here refers specifically to caffeine anhydrous. David vs. Goliath additionally contains 50 mg of di-caffeine malate, meaning the complete caffeine-containing matrix extends beyond the 400 mg caffeine-anhydrous component alone.

2-Aminoisoheptane – 250 mg

David vs. Goliath contains 250 mg of 2-aminoisoheptane, an ingredient commonly encountered in aggressive high-stimulant pre-workout formulations.

Also frequently discussed within the supplement market under the DMHA designation, 2-aminoisoheptane is one of the ingredients that most clearly differentiates David vs. Goliath from conventional retail pre-workouts.

Its inclusion alongside several additional stimulatory compounds makes the formula distinctly targeted toward experienced high-stimulant users.

N-Phenethyldimethylamine Citrate – 250 mg

Another major component is 250 mg of N-phenethyldimethylamine citrate.

This phenethylamine-related ingredient is incorporated into stimulant-oriented formulations as part of their broader central stimulation and experiential profile.

At 250 mg, it is not merely a trace inclusion and contributes to the unusually extensive stimulant architecture of David vs. Goliath.

Theobromine – 100 mg

David vs. Goliath includes 100 mg of theobromine.

Theobromine is a methylxanthine structurally related to caffeine. Although its pharmacological characteristics differ from caffeine, the two compounds are frequently combined in energy products to produce a more layered methylxanthine profile.

Theobromine also has a longer biological half-life than caffeine, making its inclusion relevant to the overall character and duration of a stimulant formulation.

Di-Caffeine Malate – 50 mg

The formula adds 50 mg of di-caffeine malate on top of its 400 mg caffeine-anydrous component.

Di-caffeine malate is a compound consisting of caffeine associated with malic acid and is used in pre-workouts as an additional caffeine-containing ingredient.

Importantly, 50 mg of di-caffeine malate does not mean 50 mg of pure caffeine. The exact caffeine contribution depends on the specifications of the raw material used.

For that reason, the most accurate description of the label is:

400 mg caffeine anhydrous + 50 mg di-caffeine malate.

Synephrine HCl – 40 mg

David vs. Goliath contains 40 mg of synephrine hydrochloride.

Synephrine is a substituted phenethylamine commonly associated with Citrus aurantium and is frequently incorporated into stimulant and thermogenic supplement formulas.

Its presence becomes particularly significant when assessing David vs. Goliath because synephrine is being combined with caffeine and several additional adrenergic/stimulatory ingredients rather than being used independently.

Alpha Yohimbine / Rauwolscine – 3 mg

The label lists:

Alpha Yohimbine 90% Rauwolscine (Rauwolfia vomitoria, root) – 3 mg

Rauwolscine, commonly called alpha-yohimbine, is structurally related to yohimbine and has substantial adrenergic activity.

This ingredient can create a considerably sharper subjective stimulant profile than caffeine alone and tends to exhibit substantial interindividual variability.

At 3 mg, its presence is one of the strongest indicators that David vs. Goliath is intended for experienced stimulant users rather than beginners.

Huperzine A 1% – 300 mcg

The label lists 300 mcg of Huperzine A 1% from Huperzia serrata whole herb.

Huperzine A is best known as a reversible acetylcholinesterase inhibitor. Acetylcholinesterase normally breaks down acetylcholine, meaning inhibition of this enzyme can modify cholinergic signaling.

The combination of a choline source and Huperzine A creates a logical cholinergic component within the larger focus matrix.

David vs. Goliath Stimulant Profile

What makes Good News Supplements David vs. Goliath particularly distinctive is not any single stimulant but the number of stimulant-related ingredients present simultaneously.

The formula contains:

• 400 mg Caffeine Anhydrous

• 250 mg 2-Aminoisoheptane

• 250 mg N-Phenethyldimethylamine Citrate

• 100 mg Theobromine

• 50 mg Di-Caffeine Malate

• 40 mg Synephrine HCl

• 3 mg Alpha Yohimbine / Rauwolscine

This creates a fundamentally different formulation strategy from a standard pre-workout containing 200–300 mg caffeine as its primary stimulant.

David vs. Goliath instead uses a multi-pathway stimulant matrix alongside a substantial citrulline and beta-alanine performance base.

David vs. Goliath Pump Formula

Hardcore stimulant products sometimes sacrifice pump ingredients in favor of increasingly elaborate stimulant blends.

David vs. Goliath takes a different approach.

The inclusion of:

8,000 mg L-Citrulline

provides a substantial nitric-oxide-focused foundation despite the product's aggressive stimulant positioning.

That makes David vs. Goliath particularly interesting for bodybuilders who want both high-intensity stimulation and meaningful pump support in the same formula.

David vs. Goliath Focus Formula

The cognitive and focus side of the formula is supported by several complementary ingredients, particularly:

• 600 mg Choline Bitartrate

• 246 mg total listed Choline

• 300 mcg Huperzine A 1%

• Caffeine

• 2-Aminoisoheptane

• N-Phenethyldimethylamine Citrate

This produces a formula designed around more than simple wakefulness.

The combination places a clear emphasis on alertness, concentration, training drive, and an intense workout experience.
