1st Endurance, Optygen HP, 120 Capsules

The 1st Endurance Optygen HP is a high-performance endurance supplement designed specifically for cyclists, runners, triathletes, and other endurance athletes looking to improve aerobic efficiency, training capacity, and recovery. Unlike stimulant-heavy pre-workouts, Optygen HP focuses on long-term endurance adaptation using clinically studied adaptogens and performance ingredients.

The formula combines premium-grade Rhodiola, Cordyceps CS-4, Ashwagandha, and Beta-Alanine to support oxygen utilization, reduce fatigue, improve lactate threshold, and enhance sustained power output. The updated HP formula contains a stronger Rhodiola dose than previous versions and delivers 1500mg of Beta-Alanine per serving to help buffer lactic acid accumulation during hard efforts.

Unlike products intended for immediate stimulation, Optygen HP is designed for consistent daily use during heavy training blocks. Benefits are intended to build over time, helping athletes maintain higher output and recover more efficiently across repeated hard sessions.
