Insane Labz is a brand known for their crazy pre-workouts like Psychotic & Possessed, along with their fat burners like Slender & Insane Cutz! But we must warn you, Insane Labz products are known for their extreme intensity, so ONLY use their products if you are an advanced user. So if you have been going to the gym for years and have extensive usage of supplements, then Insane Labz just could be what you are looking for to experience next level workouts. But if you are are a beginner fitness enthusiast or supplement user, then you should start off with another brand, as this one will just be too strong for you. This is your warning!
