X-LAB UNKWN – Pre-Workout

X-LAB UNKWN – High-Intensity Pre-Workout Formula


X-LAB UNKWN is a dietary supplement designed for experienced users seeking a potent, "classified" approach to their training sessions. Formulated in Fort Worth, TX, this pre-workout combines traditional performance ingredients with specialized botanical fractions to support high-intensity athletic performance.

UNKWN is a high-stim pre-workout dietary supplement designed for experienced gym users familiar with concentrated, stimulant-based formulas. The product is built around a proprietary blend and a classified-formula concept, combining amino acids and stimulant sources into a compact, single-scoop serving.

This formula is not positioned as an entry-level product. UNKWN is intended for individuals who already understand their personal tolerance and prefer supplements with a strong, intense profile. The product's identity, formulation style, and presentation are clearly aligned with advanced training environments.

UNKWN is best suited to gym-focused routines, including resistance training, high-intensity workouts, and demanding training sessions, where users typically choose stimulant-heavy pre-workout products.

Performance & Focus Matrix


The formula features a massive 12,800 mg Proprietary Blend designed to target multiple pathways of training optimisation:

  • Endurance & Pump Support: Includes L-Citrulline and Beta-Alanine, which may help support nitric oxide production and buffer muscular fatigue during intense sets.

  • Cognitive & Nootropic Support: Contains L-Tyrosine, Alpha-GPC, and a Neuroactive Alkaloid Complex, formulated to potentially enhance mental clarity, focus, and the “mind-muscle” connection.

  • Energy & Stimulant Synergy: A combination of Caffeine Anhydrous, Theobromine, and Amazonian Indole Fraction may provide a sustained energy increase and heightened alertness.


It is highly recommended to assess tolerance with a partial serving before moving to a full dose.
Usage Note: Due to the potent nature of the “Chemical Rush” formula, this product is strictly intended for individuals aged 18+.
