Customers say this topical product creates an intense warming sensation during workouts. Many reviews mention experiencing a tingling feeling and temporary redness when applied. Users particularly appreciate using it for arm, shoulder, and upper body routines. Common feedback includes easy roll-on application and a minty scent, though some note the fragrance is strong initially. While most experience immediate sensations, a few mention taking time to adjust to the intensity. The roll-on format receives praise for convenient use, with users noting that a small amount provides sufficient coverage.

The SteelFit Difference

What Makes Guns of Steel® Stand Out

Visibly Enhances Muscle Pumps
01

Visibly Enhances Muscle Pumps

Feel the fullness — fast. D3PA, Arginine and Citrulline combine to increase nitric oxide levels in the skin, helping deliver a tighter, more vascular look that peaks during your workout.*

Target Arms, Chest & Shoulders
02

Target Arms, Chest & Shoulders

Guns of Steel is made for upper-body training days. Just apply before you train to boost localized blood flow and enhance visual definition in the muscles that matter most.

No Crash, No Jitter
03

No Crash, No Jitter

Unlike oral pre-workouts, this formula works topically — no crash, no jitters, and no tolerance buildup. Just visible results and that feel-good, pumped-up sensation.

What's Inside Matters

Key Ingredients

We choose ingredients with intention. Every formula is built with clean, effective components that support real routines, real goals, and real life. No shortcuts. No unnecessary extras.

01
Dithiolane-3-Pentanoic Acid (D3PA)

Dithiolane-3-Pentanoic Acid (D3PA)

D3PA is a powerful antioxidant that helps support blood flow and nutrient delivery to working muscles. When applied topically, it can enhance vascularity and give your muscles that full, pumped look during training.

02
Resistem

Resistem

Resistem is a plant stem cell ingredient known for its skin-conditioning properties. It helps keep the skin looking smooth, toned, and healthy, supporting the aesthetic benefits of the pump effect.

03
L-Citrulline

L-Citrulline

L-Citrulline supports nitric oxide production, which increases blood flow and improves nutrient and oxygen delivery to the muscles. This contributes to bigger, longer-lasting pumps and better performance.

04
L-Arginine

L-Arginine

L-Arginine works synergistically with L-Citrulline to further boost nitric oxide levels and enhance vascularity. It helps create that tight, skin-stretching pump effect, giving your muscles a more defined and powerful appearance.

Stay Consistent

See the Change

Guns of Steel delivers instant pumps, but the real results come from staying consistent. Apply before every upper-body workout to help enhance circulation, improve vascularity, and bring out that full, hard look you train for. The more consistent you are, the more defined and powerful your results will be.

From the Founder

Designed to fit your life and your goals

This was one of our first formulas, and it’s still one of my favorites. We wanted something that gives you that instant motivation when you see the results in the mirror, especially on heavy training days. Guns of Steel® is about rewarding the work you’ve put in with a pump you can see and feel right away.
