The Beta-Alanine Tingle: Paresthesia

Love It Or Hate It, The Tingle Isn't Why It Works.

Beta-alanine is known for a harmless itch or tingle. But performance comes from daily use and saturation, not the tingle. Here's how to control it:

Pre-training. Want the tingle? Add a scoop to your pre-workout. Empty stomach, full effect. Feel it before the first set. Same daily dose, same result.Post-training. Rather not feel it? Take it with a balanced meal. Food blunts the tingle. Gentler on your stomach. Same daily dose, same result.

Timing doesn't matter. Take it daily, whichever way you prefer, or mix and match.

Who it's for

Built for people who train hard and want even more.

Lifters chasing PRs on strength and power
Runners who want to build durability and tighter intervals
CrossFit and Hyrox athletes pushing power and endurance
Hybrid athletes balancing two workouts a day
Anyone who has a cabinet full of random supplements
Athletes locked in on the basics who want to optimize

You don't need to be elite. You need to be consistent and want more out of every session.

The last two sets — you hit them anyway

Why I built this.

Matt Gemkow

“I train a lot. I was tired of the best ingredients being scattered across multiple products at the wrong doses. ENGINE replaces my plain creatine so I don't have to think about the three things that need daily saturation when I'm also taking a pre-workout.”

"I built the system I was piecing together for myself."

Matt Gemkow Founder, Substrate Supplements
