Inspired Nutraceuticals | DVST8 of the Union

DVST8 of the Union is a classic high-stim pre-workout built around three priorities: immediate training energy, sustained central nervous system drive, and enough pump/endurance support to keep the session productive rather than just intense. The formulation philosophy is clear: this is not a stim-free pump formula, and it is not a purely clinical minimalist build. It is an aggressive performance pre designed to create a noticeable experience from the first serving, with disclosed headline actives and additional proprietary support ingredients layered in for a more forceful subjective effect.

The disclosed performance core starts with 2,000mg L-citrulline. Citrulline works through the arginine-nitric oxide pathway, increasing arginine availability more efficiently than oral arginine itself and supporting vasodilation, blood flow, and nutrient delivery. Research commonly uses roughly 3-8g/day, so 2g sits below the fully clinical range on its own. In practice, that means you should expect some vascular and pump support, but not the kind of maximal nitric oxide effect seen from 6-8g formulas. It is helped here by 1,000mg GlycerPump™, a trademarked high-yield glycerol ingredient standardized to at least 65% glycerol. Glycerol increases fluid retention inside and around muscle tissue, improving hyperhydration, fullness, and training feel. The combination of citrulline-driven vasodilation plus glycerol-driven cell hydration is one of the more useful pump pairings in sports nutrition.

For endurance, the formula includes 1,600mg beta-alanine. Beta-alanine raises intramuscular carnosine over time, helping buffer hydrogen ions that accumulate during hard sets and high-rep work. The best-known research target is 3.2g/day, so 1.6g is exactly a half dose. One scoop gives partial daily progress; two scoops bring you to the established 3.2g benchmark. That matters because beta-alanine is not about a same-day strength spike; it is about cumulative buffering capacity over weeks of consistent use.

The stimulant architecture is what defines this product. Caffeine anhydrous at 175mg provides the fast onset, while 50mg zumXR® extended-release caffeine stretches the energy curve and helps reduce the sharp rise-and-fall pattern seen with single-source caffeine products. Total caffeine is 225mg at the full two-scoop serving. That number alone is moderate-high, but the real intensity comes from what surrounds it: 150mg EnXtra® for stimulant support without adding more caffeine, 750mg L-tyrosine as a catecholamine precursor for focus under stress, 75mg Eria Jarensis extract, 30mg hordenine, 25mg isopropylnorsynephrine, 15mg Cocoabuterol®, plus both alpha yohimbine and yohimbine HCl at 0.5mg each. That is an unmistakably aggressive stim stack with adrenergic, mood, and focus-promoting intent.

There are also undisclosed amounts of creatine monohydrate, glutamine, epicatechin, alpha-GPC 50%, choline bitartrate, and citicoline. These ingredients make mechanistic sense for strength output, recovery, and focus, but because the doses are hidden inside proprietary portions, they cannot be responsibly judged against clinical benchmarks. That is the core transparency limitation here. Compared with category norms, DVST8 of the Union is more transparent than old-school fully hidden blends because many headline ingredients are dosed, but it is not a fully disclosed label.

In terms of synergy, the formula is built to hit from multiple angles at once: caffeine plus zumXR® for onset and duration, tyrosine plus stimulants for stress-resilient focus, citrulline plus GlycerPump™ for pump and hydration, and beta-alanine plus creatine for repeated high-output efforts. Day 1, expect stimulation, elevated drive, beta-alanine tingles, and a fuller training feel. After 2-4 weeks of consistent use, the ingredients most likely to compound are beta-alanine and any meaningful creatine dose present in the blend, giving better fatigue resistance and work capacity than the first few sessions alone.
