Stacked high-energy boost with pump, sharp focus, and energy that lasts.
DVST8 of the Union is a solid high-stim pre-workout that focuses on three big things: quick energy to get you going, steady drive through your whole session, and enough pump and endurance to make your workout count, not just feel intense. It's not a no-stim pump product or a super basic one – it's built to give you a real boost you notice right away, with clear doses on the key ingredients and some extra blends for that stronger feel.
The main pump starts with 2,000mg L-citrulline. This boosts nitric oxide through the arginine pathway, helping with blood flow and getting nutrients to your muscles. Studies often use 3-8g a day, so 2g is on the lighter side by itself – expect some pump and vascularity, but not the max from higher doses. It teams up well with 1,000mg GlycerPump™, a branded glycerol that's at least 65% pure. Glycerol pulls water into your muscles for better hydration, fullness, and that pumped-up feel during lifts. Together, they make a smart combo for pumps in the gym.
For pushing longer, there's 1,600mg beta-alanine. This builds up carnosine in your muscles over time, which helps buffer the acid that builds during tough reps. Research likes 3.2g a day, so 1.6g is half that – one scoop gets you partway, two scoops hit the full mark. That's key because beta-alanine shines with steady use, not just one-off boosts; it's about building that fatigue resistance week after week.
DVST8 of the Union by Inspired Nutraceuticals contains 30mg Magnesium, a effective dose for training performance and pump.
Key Highlights
- 225mg caffeine total from two sources – 175mg fast-acting anhydrous plus 50mg zumXR® for extended release. You get a quick energy hit that doesn't drop off like those one-shot caffeine pre's.
- 1,000mg GlycerPump™ – branded glycerol with at least 65% purity. It helps hydrate your muscles, makes them feel fuller, and boosts that pump, especially if you're drinking enough water.
- 2,000mg L-citrulline – a legit pump ingredient, not just for show. It's under the 3-8g research range, but paired with GlycerPump™, it steps up for better nitric oxide and flow than going solo.
- 1,600mg beta-alanine per scoop – a dose that counts if you use it right. One scoop is half the 3.2g daily goal from studies, two scoops nail it for loading carnosine and fighting fatigue in high-rep work.
- 750mg L-tyrosine – a good chunk for focus in a pre. It helps make those brain chemicals that pair with caffeine and stims, giving you a dialed-in, motivated vibe during stressful lifts.
- 150mg EnXtra® – added to keep you alert without piling on more caffeine. It makes the energy feel smoother and more sustained, not just a big caffeine dump.
- Eria Jarensis, hordenine, and isopropylnorsynephrine amp up the stim side hard. This is what sets it apart from basic pre's – it's for folks who want that mood lift and intense drive, not generic buzz.
- Both alpha yohimbine and yohimbine HCl at 0.5mg each. They add a sharp, fired-up edge, but it's a heads-up that this is for seasoned stim users, not beginners.

Who Is This For?
- Seasoned bodybuilders who want a pre that feels powerful, uplifting, and motivating, not just okay. The 225mg caffeine with Eria Jarensis, hordenine, and yohimbine is for chasing that intense, aggressive vibe in long hypertrophy workouts.
- Mid-to-advanced lifters on high-volume push/pull/legs or splits with supersets, isolations, and quick rests. Citrulline, GlycerPump™, and beta-alanine help exactly where pump, hydration, and buffering make your session better.
- Folks tired of crashing from single-caffeine pre's. 175mg anhydrous plus 50mg zumXR® gives quick start and smoother finish.
- Guys training after work who need to shake off the fog. 750mg tyrosine, EnXtra®, and choline help flip to alert, focused mode when you gotta grind.
- Stim lovers who still want pump without ditching it. 2g citrulline isn't huge, but with 1g GlycerPump™, it's fuller than stim-only pre's.
- Athletes who like dosing by the day. One scoop for easy days, two for full – lets you adjust without all-or-nothing.
How to Use
Begin with 1 scoop in 10-12 oz cold water to test tolerance, especially if yohimbine stims are new. Seasoned users can go to 2 scoops in 16-20 oz, 20-30 minutes pre-workout – that lines up with fast caffeine while the rest builds during warm-ups. Shaker's best for mixing, since glycerol makes it thicker.
Empty stomach for quicker hit, but if stims bug you, try after a light meal to smooth it. Don't mix with other stim products, burners, or yohimbine unless you're pro at it. To max endurance, add daily creatine so you're covered beyond the hidden amount here. Use steady for beta-alanine buildup, but deload stims if it starts feeling weaker. Keep it sealed cool and dry – glycerol hates moisture and clumps easy.
What to Expect
First 0-10 minutes, it's mostly taste and waiting; empty stomach speeds it up. 10-20 minutes in, anhydrous caffeine and stims start showing – beta tingles, warmth, and that urge to lift. 20-40 minutes is prime time: focus dials in, drive ramps, and citrulline with GlycerPump™ bring the fullness. 40-90 minutes, energy holds steady thanks to zumXR® and EnXtra®, though yohimbine fans might feel the edge. Days 1-7, it's all about the immediate buzz, focus, and feel. Weeks 2-4 at full dose, beta-alanine loads carnosine for real fatigue help, and creatine adds if the dose matters over time.

Frequently Asked Questions
How much caffeine is in DVST8 of the Union?
At the full 2-scoop serving, DVST8 of the Union provides 225mg total caffeine: 175mg caffeine anhydrous plus 50mg zumXR® extended-release caffeine. The anhydrous portion drives the faster onset, while zumXR® is included to extend the energy curve and reduce the abrupt drop-off common with single-source caffeine formulas.
Is 1 scoop or 2 scoops the better way to take it?
If you are new to the formula, start with 1 scoop to assess tolerance because the total experience is amplified by yohimbine alkaloids, Eria Jarensis, hordenine, and isopropylnorsynephrine. The full 2-scoop serving is the intended formula, and it matters especially for beta-alanine because 2 scoops bring you to 3.2g, the classic daily benchmark used for carnosine loading.
Is the pump side of this formula actually strong?
It delivers a respectable training pump, but not a maximal pump formula. The 2,000mg L-citrulline supports nitric oxide production, and 1,000mg GlycerPump™ adds hyperhydration and muscle fullness; the glycerol helps compensate for the fact that citrulline is below the 3-8g range commonly used in research.
Will DVST8 of the Union make me tingle?
Possibly, yes. Beta-alanine commonly causes a harmless tingling sensation called paresthesia, especially when taken acutely before training. At the full 2-scoop serving you get 3.2g beta-alanine, which is right in the range where many users notice it.
Is this a good pre-workout for beginners?
No, this is better classified as an advanced-user formula. The issue is not only the 225mg caffeine total, but the added stimulatory complexity from yohimbine HCl, alpha yohimbine, Eria Jarensis, hordenine, and isopropylnorsynephrine.
Does the creatine in this formula replace a standalone creatine supplement?
Not reliably. Creatine monohydrate is included, but the amount is not disclosed, so there is no way to verify whether you are getting the 3-5g daily amount typically used for saturation. If creatine performance support matters to you, a standalone creatine product is still the smartest move.
Can I stack this with a fat burner?
Most users should not. Because DVST8 of the Union already contains caffeine, yohimbine HCl, alpha yohimbine, hordenine, and isopropylnorsynephrine, adding a stimulant fat burner can push the cardiovascular and anxiety side too far for many people.
How long before my workout should I take it?
About 20-30 minutes pre-workout is the sweet spot for most users. That allows the caffeine anhydrous to begin working as you warm up, while the broader stimulant and pump profile builds into the main working portion of the session.
Why does this formula feel stronger than 225mg caffeine?
Because caffeine is only part of the experience. EnXtra®, Eria Jarensis, hordenine, isopropylnorsynephrine, Cocoabuterol®, alpha yohimbine, and yohimbine HCl all shape the perceived intensity, making the formula feel sharper and more aggressive than a plain 225mg caffeine pre-workout.
Is DVST8 of the Union fully transparent?
Not fully. Many of the key actives are disclosed, including citrulline, GlycerPump™, beta-alanine, tyrosine, caffeine, and several stimulants, but the amounts of creatine monohydrate, glutamine, epicatechin, alpha-GPC, choline bitartrate, and citicoline are hidden. It is more transparent than a full black-box blend, but not a fully open-label formula.
