About Guns of Steel
Guns of Steel is a topical pump product made by SteelFit. It is designed to enhance muscle pumps and vascularity during training, while speeding up recovery after.
According to the SteelFit website, Guns of Steel features four key ingredients: Resistem, L-citrulline, L-arginine and dithiolane-3-pentanoic acid (D3PA).
D3PA is said to be a vasodilator that “stimulates the skin cells to produce nitric oxide”, while the brand says Resistem™ promotes creatine kinase activity for “fast cell regeneration”. Lastly, the manufacturer includes L-citrulline and L-arginine to raise nitric-oxide levels for “improved blood flow”.
The directions say Guns of Steel should be applied directly to the biceps and triceps 5-10 minutes before exercise.
