Black Mamba SIDEWINDER

Sidewinder is built for people who’ve outgrown standard formulas. If 200–300mg caffeine does nothing for you anymore, this is where you step up.

This is a high-stim, full-throttle formula designed for experienced users who want intensity, focus, and a proper kick before training and not something watered down.

WHAT MAKES IT DIFFERENT

You’re not just getting a caffeine hit. This is a stacked formula designed to hit from multiple angles:

Caffeine Anhydrous + Guarana + Juglans Regia

A fast + sustained release combo that keeps you switched on from your first set to your last.

This isn’t a quick spike and crash. It’s layered stimulation that carries through your session.

Citicoline (CDP-Choline)

Juniper Berry + Kigelia Africana extracts

Helps you stay dialled in when the session gets tough. Less distraction, more intent behind every set.

6g L-Citrulline Malate

4g Beta-Alanine

3g L-Arginine

This is your engine room.
Expect that driven, go-again feeling, better training output, and the ability to push deeper into sessions.

Grains of Paradise + Citrus Aurantium

These are here for one reason—training aggression and intensity. When you’re tired, this is what keeps you moving.

Himalayan Pink Salt

Helps support hydration and muscle function during hard sessions—especially when you’re pushing sweat-heavy workouts.

AstraGin®

Included to help your body make better use of what you’re taking in. No wasted ingredients.

WHO IT’S FOR

High stim junky users who need more than standard pre-workouts

Lifters chasing intensity, not comfort

Anyone who wants that “switch flipped” feeling before training

Not for beginners. If you’re new to pre-workouts, this isn’t your starting point.

WHAT TO EXPECT

Fast-hitting energy that builds and sustains

Strong mental focus during training

A more aggressive, driven training mindset

Sessions that feel sharper, longer, and harder

HOW TO USE IT

Take 1 serving (20g) 20–30 minutes before training.

If you haven’t used high-stim products before, start lower and assess tolerance.
