Review: Explosive Pumps, No Stims — A Pre-Workout That Delivers Without the Crash - 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.
Review: Great pump, better mixed - I usually mix this half-and-half with a high caffeine pre-workout for two reasons: 1) I don't like 300mg+ of caffeine all at once 2) This is slightly grainy and dense, even if mixed with a full large blender bottle Mixed I get all the benefits with a light 150mg of caffeine and a great pump. Late-night workouts with this have been fine, I just need 30-40 minutes to get it all into me because, as I said, it's dense.

### ⭐ Not good.
*by H***Y on September 19, 2023*

I’ll keep the this short and brief without getting into a bunch of details. This stim free pre workout has done nothing for me, I’ve tried 1 scoop, 1 1/2 scoops, and I’m now at 2 scoops. Still nothing. Next is the absolutely horrible taste and consistency of this powder. I wouldn’t even call it a powder, it looks like pebbles of salt and doesn’t mix to well. I’ve literally had to push myself to try and finish the whole container but I gave up and wrote this review instead. Then there’s the price… it’s just outrageous, the stim free pre workout I found much success with is half this price and the same amount of servings. I honestly doubt it has what it advertises in it, at least not in the amounts it boasts. Steer clear of this one guys, head over to body building.com and try their stim free pre, it’s a world of difference!
