6g Glycersize™ for fuller muscles and longer-lasting pumps
Raw Nutrition Pump 2 has one main job: boost your workout fullness, keep muscles hydrated, and amp up the pump with a solid standalone glycerol dose. It's not a full pre-workout. It's just a pump booster with 6g of Glycersize™, a 65% glycerol powder that gives you about 3.9g of actual glycerol per scoop. That's key because glycerol is one of those ingredients that really affects how much fluid your body holds onto, and you feel it during training—muscles get fuller, hydration stays strong, and the pump hangs around longer even when the workout drags.
Glycerol acts as an osmolyte, which means it helps pull water into your cells and keep it there. In the gym, that means your muscles look and feel more volumized—rounder, easier to pump up, and they don't fade as quick between sets. It basically draws water into your body and holds it in places like blood and cells, supporting better hydration. That's why studies look at it for extra hydration and performance, especially in heat or tough sessions where staying hydrated affects how you perform. Real talk: full hyperhydration in research uses way bigger doses based on body weight, so Pump 2 isn't that level in one scoop. But it gives a practical dose you can use in the gym, right at the start of the range that makes a difference for pumps and performance.
The branded form is a big deal. Glycersize™ is used because pure glycerol is tough to turn into a powder that mixes well. These branded versions make it easier to handle, more consistent, and better to mix than old liquid glycerol, even if some clumping happens.
Key Highlights
- 6g Glycersize™ per serving — a straight-up glycerol dose for real pump help. With 65% glycerol powder, you get about 3.9g actual glycerol, which is solid for anyone wanting hydrated, fuller workouts.
- Trademarked glycerol source — Glycersize™ is a branded powder picked for its consistency and reliability. Glycerol can be tricky to work with, so a branded version means you get a steady product every time, better than generic stuff.
- Approx. 3.9g active glycerol — that's the real number after the 65% standardization. It's at the lower end of doses that actually help with performance and pumps, way better than tiny amounts hidden in blends.
- True stimulant-free pump support — no caffeine, no yohimbine, no heavy stims, no crash. Pump 2 is perfect for late workouts, folks sensitive to stims, or anyone adding pump without messing up their energy setup.
- Built for stacking — glycerol goes great with nitric oxide boosters like citrulline or nitrates. If you're already using those, Pump 2 adds the hydration side to make your pump feel way fuller.
- No proprietary blend — everything's listed clear on the label with doses. In a world where pump products hide weak glycerol behind fancy names, this transparency is a real win.
- Purposefully minimalist formula — one ingredient, one way it works, one clear use. It's easy to figure out, stack, and tweak compared to formulas crammed with pump, focus, energy, and endurance stuff at weak doses.
- Supports cellular fullness during high-volume training — glycerol acts as an osmolyte, helping hold water in your body for that swollen, pumped muscle feel during hypertrophy sets. You see and feel it in the mirror and during reps.
Who Is This For?
- Bodybuilders in hypertrophy phases who rate workouts by how full muscles feel, how good contractions hit, and if the muscle stays pumped from start to finish. That 6g Glycersize™ is perfect for training where cell fullness and lasting pumps boost feel and what you see.
- Lifters with a stim pre-workout that's weak on pumps. Pump 2 adds standalone glycerol to stack without changing your caffeine, letting you tweak blood flow your way.
- Stim-sensitive folks wanting better workouts without caffeine or other CNS hits. Just Glycersize™ targets hydration and fullness straight up, no forced intensity.
- Evening lifters needing a pre-effect without messing up sleep. Glycerol pumps make late sessions feel solid without the crash from caffeine.
- Athletes in hot gyms or sweaty workouts where dehydration kills performance. Glycerol helps hold fluid, making it smart when hydration affects endurance and pumps.
- Physique competitors or photo-shoot preppers tuned into muscle roundness. With water and carbs, Pump 2 helps that fuller, denser look they want.
How to Use
Mix 1 scoop in water 20-30 minutes before training. Label says 6-8 oz, but for real glycerol effects, go beyond that with more water before and during—it's all about fluid for this to work. Use a shaker since glycerol can clump from moisture. Jump in with a full scoop if pumps are your thing; half is for testing tummy comfort or stacks. Fine on empty stomach or light meal, but heavy food might slow things down with less efficient hydration. Stack with citrulline, nitrates, creatine, electrolytes, or intra carbs for a full setup. No cycling needed. Keep it sealed cool and dry—some clumping is normal since glycerol pulls moisture.
What to Expect
Minutes 0-10: it's not a stim, so no buzz or rush—just a chill addition. Minutes 10-20: with enough water, it's starting to hydrate, but you feel it most once you start lifting. Minutes 20-40: during sets, especially higher reps, pump builds quicker and feels thicker. Minutes 40-90: glycerol keeps muscles fuller longer instead of going flat. Days 1-7: you feel it right away, no buildup needed—test it in your first workouts while tweaking water. Weeks 2-4: gets better with dialed-in hydration, stacking, and timing, since it doesn't load like creatine or beta-alanine.

Frequently Asked Questions
What is the active ingredient in Raw Nutrition Pump 2?
Pump 2 contains one active ingredient: 6g of Glycersize™, a trademarked 65% glycerol powder. That means each serving delivers about 3.9g of actual glycerol, which is the physiologically relevant number for hydration and pump support.
Is Pump 2 a complete pre-workout?
No. This is a standalone glycerol-based pump product, not a full pre-workout. It contains no caffeine, no citrulline, no beta-alanine, and no nootropics, so it is best used either on its own for hydration/fullness or stacked with your usual pre-workout.
How should I take Pump 2 for the best pump?
Take 1 scoop 20-30 minutes before training and prioritize water intake. Glycerol works by helping the body retain fluid, so the quality of your result depends heavily on how well hydrated you are before and during the workout.
Why does Pump 2 clump in the tub?
Because glycerol is hygroscopic, meaning it naturally attracts moisture from the air. That is normal for standalone glycerol products and does not mean the ingredient is damaged or ineffective.
Can I stack Pump 2 with a stim pre-workout?
Yes, and that is one of the best uses for it. Pump 2 adds glycerol-based hydration and volumization to pre-workouts that already cover energy and focus but are weak on pump support.
Does Pump 2 contain caffeine?
No. Pump 2 is stimulant-free, so it will not provide the mental energy or alertness of a caffeinated pre-workout. Its effect is centered on hydration, fullness, and pump quality.
How much actual glycerol do I get from 6g of Glycersize™?
Glycersize™ is standardized to 65% glycerol powder, so 6g provides approximately 3.9g of actual glycerol. That is the important number when comparing it to other glycerol products.
Is this good for evening workouts?
Yes. Since there are no stimulants, Pump 2 is a strong option for late-day training when you want better pumps and hydration support without risking sleep disruption.
Do I need to cycle Pump 2?
No. There is no stimulant tolerance or loading requirement with this formula, so it can be used whenever pump quality and workout hydration are priorities.
Will Pump 2 help if my current pre-workout already has pump ingredients?
Often yes, especially if your current pre-workout uses small glycerol amounts or none at all. Glycerol adds a different mechanism than nitric oxide boosters, so stacking it with citrulline or nitrates can noticeably improve fullness and pump duration.
