The Clear Answer: No Caffeine in Bucked Up Non Stim

The term "non stim" indicates the product contains zero caffeine, specifically designed for individuals seeking pre-workout benefits without stimulants. This formula is suitable for those sensitive to caffeine, exercising in the evening, or taking a stimulant break. Instead of caffeine, it utilizes clinically studied ingredients to support pump, endurance, and focus. Unlike some products with proprietary blends, Bucked Up offers a transparent ingredient list.

Key Performance-Enhancing Ingredients

The benefits of Bucked Up non stim come from its non-caffeinated ingredients, listed transparently on the label.

Citrulline Malate for Enhanced Pump

Citrulline Malate, often dosed at 6 grams, boosts nitric oxide for increased blood flow and muscle pump, enhancing performance and endurance.

Beta-Alanine for Endurance

Beta-Alanine supports strength, endurance, and muscle growth by buffering lactic acid, delaying fatigue. The common tingling sensation (paresthesia) is harmless.

Nootropics for Mental Focus

Nootropics like AlphaSize® Alpha GPC improve mental clarity and focus without the overstimulation of caffeine.

Other Ingredients for Recovery and Hydration

Ingredients like Deer Antler Velvet Extract aid recovery, while AstraGin® enhances absorption. Himalayan Rock Salt and Taurine support hydration and electrolytes.

When to Choose a Non-Stimulant Pre-Workout

A non-stimulant pre-workout like Bucked Up non stim is beneficial in several scenarios:

Evening Workouts: Avoids disrupting sleep.
Caffeine Sensitivity: Provides benefits without jitters or anxiety.
Cycling Off Caffeine: Helps maintain performance while taking a break from stimulants.
Avoiding the Crash: Offers sustained energy without a post-workout crash.
