Welcome at Healthcare Magic. I read your question and I understand your concern. Endura mass a weight gaining supplement if used judiciously doesn t cause side effects. It cause side effects in unjudicious use mainly decrease muscle mass, increase risk of depression, fatty liver as it contains hyperglycemic sugars and traces of steroids. I would like to recommend you the following schedule. 1. eat three times with two snacks in between 2. don t drink water before meal as it decreases satiety. in other times drink at least 8-12 glasses of water. 3. Have sound sleep at least 8 hours daily 4. Eat proteinacious diets like dairy products, oils 5. Avoid trans fast 6. Do regular aerobic exercise. 7. Do regular anaerobic excersize like weight gaining as eating will increase your fats not muscle mass 8. Do daily weight. 9. Avoid over the counter weigh gain supplements. 10. take juices, large starch containing carbohydrates. Hope it helps best.
