Black Blood Caf+ 300 Gr is an advanced version of BioTechUSA's pre-workout, focused on providing extreme energy. Unlike its "Nox" version, this formula focuses on delivering a high dose of caffeine combined with Beta-Alanine to reduce muscle fatigue and L-Tyrosine to enhance focus. This supplement is especially suitable for athletes and bodybuilders looking to push their performance to the limits in tough workouts. Its 300-gram packaging guarantees a high concentration of doses, making it ideal for those needing an extra boost during exercise sessions. Moreover, its carb-free composition makes it suitable for definition or ketogenic diets. Due to its high caffeine content, it is recommended to assess personal tolerance before increasing the dose and to avoid consumption close to sleep.
