Kill your workout with Insidious by Murdered Out! It's time to murder the competition with our brand new, high-performance pre-workout supplement, Insidious. Designed to exceed the needs of fitness fiends, gym-goers, and sports-pros everywhere. Insidious is packed full of powerful ingredients that combine to supercharge your physical performance, again and again.

Murdered Out Insidious, Helping you to stay stronger, react quicker, last for longer, pump harder, and recover better. We know you're hell-bent on maximising every second of every workout you do. But to do that, you need the fuel to fire up your energy levels, push through the pain, and get past the demons in your head. That's what we designed Insidious to do. Ignite your physical potential so you kill your workouts every time and go way beyond your personal best. Without feeling like you've been to hell and back afterwards. So, if you're serious about achieving success by stealth and avoiding all the blood, sweat, and tears that comes with ineffectual gym sessions Insidious is the supplement for you. The devil's in the detail, right?

Mix one heaped scoop (9.25g 1x1cc scoop) with 125-250ml of cold water for a single serving or 2 heaped scoops (18.5g 2x11cc scoops) for a double serving with 250-300ml water.

Take around 20 to 30 minutes before training to fuel extreme performance levels. Exceed this dosage in any 24-hour period and you're playing with the devil. If you value your sleep, avoid taking Insidious four hours before bedtime.
