Pump Serum Non Stim Pre-Workout - Fully Loaded Stimulant Free Pre Workout for Extreme Pumps, Vascularity & Muscle Fullness, with L-Citrulline, HydroPrime & Nitrates, Tropical Pineapple, 40 Servings

idk why I waited so long to switch. powder never mixed right for me. liquid is stupid easy and works the same, if not better.

The taste is absolutely foul, the power doesn't mix, the serving is enormous, and there is no feeling whatsoever I've taken anything with an active ingredient at all. I'd try Gethins zero stim pre or another brand to actually feel a pump.

Pump Serum by Huge Supplements delivers exactly what I want in a non-stim pre-workout: massive muscle pumps, clean focus, and no crash. 🔹 The pumps are real — noticeable fullness within 20 minutes. 🔹 No caffeine = no jitters or late-night sleep issues. 🔹 Clean label with fully dosed ingredients like Citrulline, Agmatine, and GlycerPump. 🔹 Focus ingredients like L-Tyrosine help keep you mentally dialed in. 🔹 Jungle Juice flavor tastes solid and mixes easily. ⚠️ It’s a big scoop — but worth it. If you're new to stim-free pre’s, start with half. Bottom line: For muscle pumps, endurance, and clean energy, Pump Serum hits hard. It’s now part of my regular training stack. ✅ Highly recommended.

Good stuff, taste isn’t wonderful though. protip: I mix the island dream flavor with Sunny D. A lot of not so great tasting preworkouts you can mix with Gatorade or something else with complimenting flavors and it tastes 100x better.

Great ingredients, good flavor, and full pumps!

Want to be completely honest, pineapple flavor is terrible not sure if all flavors are like this but it’s super chalky, like most people have stated found a few clumps. Pumps are decent need 2 scoops,

Like the flavor mix well, transparency is always good, but unfortunately am almost done with the product and I haven't felt the pumps I can get qith other products. Price too expensive. There better pump products at more reasonable prices

Buy a product you already know works. I tried this product along with the wrecked pre-workout. I’m 75% through both tubs, both are obviously underdosed, and won’t buy again. I don’t really care too much about the taste of the pre I drink, but this stuff is absolutely terrible. Drank the recommended dose to start and after a couple days added another half scoop. Made me nauseas. Pre workouts have always been a slippery slope regarding proprietary blends and actually getting what they tell you is in the product. I’ve been drinking SuperHuman for years and thought I’d try something new that also looked promising on the ingredient label. Lesson learned. Back to SuperHuman for me. Not recommended. Oh yeah and one of 2 tubs I bought was missing a scoop. And the product was chunky, doesn’t matter to me but to some people it may.
