★★★★★ 4.7 / 5 from verified buyers · Caffeine-free · Naturally sweetened · No jitters

Clean label, naturally sweetened.

Stevia-sweetened, no sucralose, no artificial sweeteners, no dyes, no proprietary blends. Every dose disclosed — a pre-workout you can actually read.

Clinical-dose pump.

6,000mg L-Citrulline Malate widens your vessels for real oxygen and blood flow — the pump without the espresso shot.

Zero caffeine.

Real energy from blood flow, not stimulants — no jitters, no crash, and your sleep stays untouched, morning or night.

Does a caffeine-free pre-workout actually work?+
Yes — caffeine was never what built the pump. Blood flow is. Flowy's 6,000mg clinical dose of L-Citrulline Malate raises nitric oxide so your vessels widen and more oxygen reaches working muscle. You get the pump, endurance and focus — just without the stimulant.
What's it sweetened with? Any artificial ingredients?+
Naturally sweetened with stevia and a trace of organic cane sugar. No sucralose, no ace-K, no artificial sweeteners, no dyes, no proprietary blends — every dose is disclosed. 5 calories, real lemon lime.
Will it keep me up at night?+
No. Flowy has zero caffeine, zero green tea extract and zero guarana — nothing with a half-life that lingers. The energy comes from blood flow and electrolytes, not a stimulant spike, so you can train morning or evening and your sleep stays untouched.
Will I feel tingles or itch?+
No. We deliberately left beta-alanine out — the tingles some pre-workouts give you are a problem when you're trying to wind down later.

What evening lifters say after tub one.

EXCELLENT caffeine-free pre-workout.

I drink a lot of coffee in the morning and I don't need any extra caffeine from a pre-workout. This is the first one I've found that makes a perfect blend of excellent ingredients and it really helps my workouts.

What I have been searching for.

I've been trying different 'no caffeine' pre-workout powders for years and Flowy is my favorite. It gives me that energy boost without interrupting my appetite for dinner or sleep.

Great for feeling your best.

I really like that there's no caffeine and that it helps with bloodflow. It doesn't give you jitters, it just makes you energized and you feel good. Tastes great, too.
