Additional Information
Stim Hub Sour Stim Heads is a limited edition high-stimulant pre-workout designed for those who want something completely different from the typical sweet or refreshing flavour profile. Delivering an intensely sour experience alongside a fully loaded performance formula, Sour Stim Heads combines powerful energy, focus, endurance, and nootropic ingredients to create a truly unique pre-workout experience. Each serving contains 400mg of caffeine paired with 150mg of L-Theanine to deliver strong, clean energy without the harsh crash commonly associated with high-stimulant products. The formula is further enhanced with 300mg of English Walnut extract to support mood, motivation, and euphoric energy, while 600mg of Alpha GPC helps improve focus, concentration, and mind-muscle connection during training sessions. To support endurance and workout performance, Sour Stim Heads also includes 3.5g of Beta-Alanine, helping reduce fatigue and improve muscular endurance throughout your session. The tingling sensation associated with Beta-Alanine also adds to the product’s intense “sour challenge” experience. What makes Sour Stim Heads especially unique is the adjustable sour challenge. For the ultimate sour hit, mix 1 scoop with 100ml of water. For a Mega Sour experience, use 200ml of water. For a Super Sour flavour, mix with 400ml, or for a milder experience, combine 1 scoop with 500ml of water. Whether you are challenging yourself or your training partners, Sour Stim Heads delivers a one-of-a-kind pre-workout experience before this limited edition release sells out.How To Use
