PREX Underground – Pep(tide-Powered Pre-Workout for Muscle Growth, Fat Loss & Metabolic Performance

$125.00 USD

PREX Underground is the ultimate next-generation pre-workout designed to take your training to the next level.* Unlike traditional stimulants, this advanced formula combines cutting-edge peptides, nootropics, and thermogenic ingredients to enhance muscle growth, accelerate fat loss, optimize metabolism, and improve mental focus.*

Key Benefits:

  • Enhanced Muscle Growth: SLU-PP-332 acts as an exercise mimetic peptide, helping muscles grow and recover faster while improving endurance.*

  • Accelerated Fat Loss: AOD-9604, a fat-burning peptide derived from HGH, targets stubborn fat, particularly around the midsection, without unwanted side effects.*

  • Metabolic Optimization: MitoBurn™ (L-BAIBA) boosts mitochondrial output, increases thermogenesis, converts white fat to brown fat, and supports glucose regulation.*

  • Improved Focus & Mind-Muscle Connection: Noopept enhances cognitive clarity, BDNF production, and focus during workouts for better reps and sets.*

  • Clean Energy & Circulation: Built on the PREX base formula, enjoy sustained energy, improved blood flow, and intense “pump” without jitters or crashes.*

Why PREX Underground Works:
This pre-workout doesn’t just give you a temporary energy boost—it speaks directly to your body’s signaling pathways to maximize performance, fat metabolism, and muscle growth.* It’s ideal for athletes and fitness enthusiasts who want real results and a more defined, toned, and cut physique.*

How to Use:
Mix one scoop 20–30 minutes before training or any activity requiring energy and focus. Adjust based on tolerance. Not recommended for beginners or those sensitive to stimulants.*

Label Update: Each serving contains 500mcg AOD-9604 and 25mg Noopept for enhanced fat loss, focus, and performance.*
