Inspired Nutraceuticals DVST8:25 is the Decade Edition — the 10th anniversary pre-workout built to be the most advanced DVST8 in the brand's history and a tribute to the DVST8 White Cut that changed the pre-workout category in 2015. Per full two-scoop serving: 8,000mg dual-source Citrulline (6,000mg pure L-Citrulline + 2,000mg NO3-T® Citrulline Nitrate), 1,000mg NO3-T® Betaine Nitrate, 1,000mg OxiGRO™ (Amla, Watermelon, Pine Bark, Grape Seed), 200mg CocoaPlex™ VO2 Cocoa Extract, 5,000mg Beta-Alanine, 500mg Adenosine-5'-Triphosphate (ATP), 3,222mg ENDLESS™ Electrolyte Blend, 2,000mg L-Tyrosine, 1,000mg Mucuna Pruriens (20% L-Dopa), 1,000mg Cholidine™ (Choline Bitartrate + UMP), 400mg Catuaba Bark, 400mg Caffeine Anhydrous, 40mg SalidroPure™ (fermented Salidroside), and 2mg MaxCatalyst™ absorption enhancer. 30 single-scoop or 15 double-scoop servings. Engineered neurovascular synergy across three performance pillars: pump, dopaminergic focus, and endurance. Flavors: Malibu Breeze, Black Rainbow, Pink Stardust. California Prop 65 Warning applies.†
DVST8 White Cut launched in 2015 and changed the pre-workout category in a specific, documented way: it was one of the first fully transparent pre-workouts to simultaneously be extremely effective, legitimately hard-hitting on stimulants, and available in a 40/20 serving structure (40 one-scoop or 20 two-scoop) that let brands put more active ingredients in a container without raising the price. That combination — transparency, effectiveness, value — created a template that dozens of brands have since followed. DVST8 Crimson, Worldwide, DVST8 of the Union, and DVST8 Dark each evolved the formula while maintaining the brand's DNA.†
DVST8:25 is the 10th anniversary version — what Inspired calls "the most expensive DVST8 we've ever produced." The formula was not built to margin. Inspired's own product copy states they "didn't cut corners, didn't chase profit" — this was built as a thank you to the Inspired faithful. The formula reflects that: five novel or branded ingredients not seen in previous DVST8 versions (OxiGRO™, CocoaPlex™, SalidroPure™, Cholidine™ UMP, NO3-T® Betaine Nitrate), the highest Beta-Alanine dose in any DVST8 (5g), the most comprehensive electrolyte blend the brand has used in a powder, and a dopaminergic focus stack centered on Mucuna Pruriens L-Dopa and Catuaba Bark that no previous DVST8 has included.†
Inspired frames DVST8:25 around three simultaneous performance pillars: Neurovascular (pump and blood flow), Dopaminergic (mood, motivation, and focus), and Endurance (work capacity and fatigue resistance). The design intent is synergy across all three — not a formula where the pump stack and the energy stack operate independently, but one where blood flow, neurotransmitter state, and muscle buffering reinforce each other throughout the session. Understanding each pillar explains why the formula is built the way it is.†
DVST8:25 addresses the NO-dependent vasodilation pathway through two complementary forms of Citrulline simultaneously. Pure L-Citrulline at 6,000mg drives the arginine-eNOS-NO pathway: Citrulline converts to arginine in the kidney, arginine is the substrate for eNOS (endothelial nitric oxide synthase), and eNOS produces NO that relaxes vascular smooth muscle and produces vasodilation. The 6,000mg dose of actual Citrulline is above the threshold used in most positive sports performance research.†
Citrulline Nitrate (NO3-T®) at 2,000mg adds the nitrate-nitrite-NO pathway — a completely different enzymatic route to nitric oxide production. Nitrates from food or supplementation are reduced to nitrite by oral bacteria, then converted to NO by nitrite reductases in exercising muscle tissue under hypoxic conditions — specifically during the most intense moments of training when oxygen tension is lowest and NO demand is highest. NO3-T® Citrulline Nitrate is a dual-action compound: it provides actual Citrulline (which feeds the arginine-eNOS pathway) AND dietary nitrate (which feeds the nitrate-nitrite-NO pathway). Two NO pathways from one compound, with additional coverage from the pure Citrulline on the first pathway. The total 8,000mg Citrulline from both sources plus the independent nitrate mechanism represents one of the most complete NO coverage architectures in the DVST8 lineage.†
Betaine Nitrate is the second NO3-T® compound in the formula — Betaine (trimethylglycine) bound to nitrate. It provides additional exogenous nitrates for the nitrate-nitrite-NO pathway alongside the Citrulline Nitrate, plus the Betaine component's osmotic cell volumization and methyl donation effects. Inspired's formulation note is accurate: at 1,000mg the Betaine content is below the 2,500mg threshold used in most positive performance research — but the primary purpose of this inclusion is the nitrate contribution and the combined blood flow effect, not the Betaine-specific osmotic and power output benefits. The total exogenous nitrate load from both NO3-T® compounds is meaningful for sustained vascular dilation throughout the session.†
OxiGRO™ is a proprietary antioxidant and blood flow blend combining four plant-derived compounds known for vascular and circulatory support. Amla (Indian Gooseberry / Phyllanthus emblica) is one of the richest natural sources of Vitamin C and polyphenols — research has shown Amla extract improves endothelial function and reduces oxidative stress in the vasculature. Watermelon Powder provides L-Citrulline from a natural food source alongside lycopene and other phytonutrients — adding further to the formula's Citrulline-derived NO support through a whole-food matrix. Pine Bark Extract (Pycnogenol-class oligomeric proanthocyanidins) has documented effects on nitric oxide production enhancement and endothelial health. Grape Seed Extract provides proanthocyanidins that protect the vascular endothelium from oxidative damage and reduce ACE activity (complementing vasodilation). Combined, OxiGRO™ addresses vascular health and blood flow enhancement through antioxidant, polyphenol-mediated, and food-derived Citrulline mechanisms.†
CocoaPlex™ is a cocoa (Theobroma cacao) extract standardized for its flavanol content. Cocoa flavanols — particularly epicatechin — have documented effects on nitric oxide production through eNOS activation, improving vascular function and increasing blood flow. Research on cocoa flavanol supplementation has specifically documented improvements in VO2 kinetics during exercise — the rate at which muscles adapt their oxygen uptake to exercise intensity. Improved VO2 kinetics means the aerobic energy system adapts faster to increasing exercise demands, reducing the oxygen deficit at the start of high-intensity efforts and improving overall exercise efficiency. CocoaPlex at 200mg provides the cocoa flavanol dose associated with meaningful cardiovascular support.†
DVST8:25's cognitive stack is built around dopamine — the neurotransmitter responsible for motivation, reward anticipation, mood, and the driven, purposeful energy state that separates a productive training session from just going through the motions. This is a meaningfully different approach from the acetylcholine-first cognitive stacks (Alpha GPC + Huperzine A) used in many high-stim pre-workouts. Inspired's design is dopaminergic saturation through multiple complementary pathways simultaneously.†
L-Tyrosine at 2,000mg is the rate-limiting amino acid for the entire catecholamine synthesis pathway — dopamine, norepinephrine, and epinephrine all derive from Tyrosine via DOPA. At 2,000mg, Tyrosine provides a substantial precursor reservoir to maintain catecholamine synthesis rates under the dual stress of 400mg caffeine and heavy training. Catecholamine depletion is the primary mechanism of the mid-workout energy crash — Tyrosine at meaningful doses prevents this by ensuring the synthesis pathway doesn't run out of substrate.†
Mucuna Pruriens seed extract at 1,000mg standardized to 20% L-Dopa delivers approximately 200mg of L-DOPA — the immediate biochemical precursor to dopamine that crosses the blood-brain barrier and converts to dopamine in dopaminergic neurons. This is meaningfully different from Tyrosine's precursor role: Tyrosine is two enzymatic steps removed from dopamine (Tyrosine → DOPA → Dopamine), while L-DOPA is one step removed (DOPA → Dopamine). L-DOPA supplementation more directly and rapidly raises brain dopamine levels than Tyrosine alone. The combination of 2,000mg Tyrosine (upstream precursor) and 1,000mg Mucuna at 20% L-Dopa (direct precursor) is a two-layered dopamine support system — the Tyrosine maintains the longer-term precursor pool, the L-DOPA provides immediate dopamine synthesis substrate. The elevated dopamine produces the motivated, driven, euphoric training state that Inspired describes as the formula's mood and mental resilience dimension.†
Cholidine™ is Inspired's branded combination of Choline Bitartrate and Uridine-5'-Monophosphate (UMP) — a pairing with specific and complementary neurological rationale. Choline Bitartrate provides the choline substrate for acetylcholine synthesis, supporting the neuromuscular connection and attention dimension of cognitive performance during training. Uridine-5'-Monophosphate (UMP) is a nucleotide that crosses the blood-brain barrier and is incorporated into cell membranes as part of the CDP-choline (citicoline) synthesis pathway — it works synergistically with choline to increase phosphatidylcholine levels in brain cell membranes, improving membrane fluidity and neurotransmitter receptor density. Research combining choline and uridine sources has documented enhanced cognitive performance, improved memory formation, and mood regulation through this combined membrane and neurotransmitter mechanism — specifically through what neuroscientists call the "Kennedy pathway" for phospholipid synthesis. This is a more sophisticated choline approach than simple Choline Bitartrate alone and produces qualitatively different cognitive effects.†
Catuaba (Trichilia catigua) bark extract is a Brazilian tree bark with a long traditional use as a nervous system stimulant and libido enhancer. Modern analysis of Catuaba's bioactive compounds shows alkaloid and flavonoid content that activates dopaminergic neurotransmission — increasing dopamine receptor sensitivity and dopamine release through mechanisms involving the mesolimbic dopamine system. Research on Catuaba extract documents anti-anxiety effects, mood elevation, and energy enhancement through these dopaminergic pathways, as well as improvements in sexual function. At 400mg Catuaba Bark is at the lower end of the typical dosing range (400-1,000mg), but within the range where its mood and focus effects are noticeable alongside the Mucuna L-DOPA and Tyrosine's catecholamine precursor loading. Catuaba's combination with Mucuna L-DOPA creates a dual dopaminergic approach: L-DOPA increases dopamine production, while Catuaba's alkaloids enhance the dopaminergic response at the receptor level.†
Five grams of Beta-Alanine is the highest dose in any DVST8 version and 1,800mg above the standard 3,200mg clinical dose used in most pre-workout research. The "MAXED" designation reflects this above-standard dosing. Beta-Alanine's mechanism — providing the rate-limiting precursor for muscle Carnosine synthesis — accumulates over days and weeks of consistent supplementation. The paresthesia (tingling) from 5,000mg will be more pronounced than at 3,200mg — this confirms the dose is bioavailable and active. The elevated dose supports faster carnosine saturation over the first 2-4 weeks of consistent DVST8:25 use.†
ATP (Peak ATP® is the typical branded form in sports nutrition — the Inspired product page does not specify the brand) at 500mg is the direct energy currency of cellular metabolism. Oral ATP supplementation has historically been questioned for bioavailability — the concern being that ATP is broken down in the digestive process before absorption. However, research on oral ATP supplementation has documented improved exercise performance, muscular power, and recovery in human subjects, with proposed mechanisms involving adenosine receptor stimulation in blood vessels (increasing vasodilation and blood flow) and direct cellular energy delivery through intestinal absorption pathways. At 500mg, ATP in DVST8:25 contributes a performance and blood flow mechanism that operates independently of the NO-pathway pump compounds.†
The ENDLESS™ Electrolyte Blend (Potassium Citrate, Sodium Citrate, DiMagnesium Malate) at 3,222mg is a comprehensive electrolyte matrix at a meaningful dose — the same formulation used in Inspired's hydration RTD line. Sodium maintains fluid balance and supports muscle cell hydration critical for contractile function. Potassium is the primary intracellular electrolyte essential for action potential generation in muscle and nerve cells. Magnesium (as DiMagnesium Malate — magnesium bound to Malic Acid, a Krebs cycle intermediate) supports ATP synthesis, GABA receptor function, and over 350 enzymatic reactions. At 3,222mg total, the ENDLESS™ blend provides genuine electrolyte support — not a token inclusion — for maintaining hydration and neuromuscular function through a high-output session with 400mg caffeine (which is diuretic) and intense physical stress.†
SalidroPure™ is NutriScience Innovations' purified fermented Salidroside — the primary bioactive compound from Rhodiola rosea, produced through a fermentation process that increases the purity and potency of Salidroside versus crude Rhodiola extract. Salidroside (Rhodioloside) is the phenylpropanoid glycoside responsible for most of Rhodiola's adaptogenic effects: it activates AMPK and promotes mitochondrial biogenesis, reduces cortisol elevation under stress, modulates the monoamine oxidase system (contributing to mood and fatigue resistance), and has documented VO2 max and endurance enhancement in multiple human trials. At 40mg of purified Salidroside versus the 2-4% standardization found in most Rhodiola extracts, SalidroPure™ provides more concentrated Salidroside per milligram than standard Rhodiola extracts — making it an efficient way to include meaningful Rhodiola-class adaptogenic activity in a pre-workout formula.†
DVST8 Dark is Inspired's existing high-stim pre-workout with 400mg caffeine, Synephrine (as SYNapsis), NeuroCap (Baical Skullcap), CoLEAN™ (Alpha-GPC 300mg + Citicoline 200mg), NO3-T® Arginine Nitrate, and L-Citrulline. DVST8:25 shares the 400mg caffeine and the NO3-T® nitrate platform but makes several meaningful formula changes. The dopaminergic stack is fundamentally different — Dark uses CoLEAN's Alpha-GPC and Citicoline for acetylcholinergic focus, while :25 uses Mucuna L-DOPA + Catuaba + Cholidine™ (Choline Bitartrate + UMP) for a dopamine-first approach. Dark includes Synephrine for thermogenesis — :25 does not. Dark's Beta-Alanine is 3,200mg; :25's is 5,000mg. :25 adds OxiGRO™, CocoaPlex™, SalidroPure™, ATP, and the ENDLESS™ electrolyte matrix that Dark doesn't include. :25 is the broader, more complete formula with unique innovation in every pillar.†
Mix 1-2 scoops in 10-14oz of cold water 20-30 minutes before training. New users: start with 1 scoop (200mg caffeine, half-doses of all active ingredients) to assess individual tolerance before advancing to 2 scoops. Do not exceed 2 scoops in any 24-hour period. Do not combine with other caffeinated products, stimulants, or fat burners. Do not take within 6 hours of bedtime. Expect significant Beta-Alanine paresthesia at 2 scoops (5,000mg) — this is normal and confirms bioavailability. Not for persons under 18. Not for pregnant or nursing women. Consult a physician before use if taking any prescription medications or having any medical condition. California Prop 65 Warning applies.†
