Welcome to HCM, Oxyelite Pro is not indicated to lower cholesterol. Many states and nations have banned its use due to the safety risk associated with heart and liver failures. I especially think you need to finish growing before thinking about trying supplements. Energy drinks can also be very dangerous speeding up your heart and putting it at risk for strokes especially if combined with caffeine. I suggest that you make an appointment with a sports dietitian, don t believe everything you read, set up a training program, eat a balanced diet with an emphasis on lean protein up to 1.8 g/kg (although should be individually assessed). Switch to good fats like canola oil, olive oil, omega 3s. Most importantly, rely on yourself and not a pill. Regards, Kathy J Shattler, MS,RDN
