How It Works

Follow these steps to get the most out of INFRNO — your ultimate pump and performance pre-workout.

1️⃣ Mix 1 scoop (approx. 21.5g) with 250–300 ml of cold water about 20–30 minutes before training.

2️⃣ Train hard. Feel the muscle fullness, vascularity, and focus kick in as INFRNO’s ingredients peak.

3️⃣ Stay hydrated. Keep sipping water during your session to maximise hydration and performance.

4️⃣ Cycle smart. Use INFRNO for 8–12 weeks, then take a 2–4 week break to maintain maximum effectiveness.

💡 Pro Tip: For insane pumps, stack INFRNO with adequate carbs and hydration before your workout.

⚠️ Do not exceed 1 scoop in 24 hours. Intended for use on training days only.
