No Crash, No Jitter

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.

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.

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.

Resistem
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.

L-Citrulline
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.
