Hello, Endura is rich in table sugars and corn syrup, hyperglycemic carbohydrates cause radical damage to muscle tissues. May contain traces of steroid, may increase the growth of body hair as well as facial hair, may cause hormonal imbalance, may interfere with the hormonal system, fatty liver as it contains a lot of milk products such as whole milk, skimmed milk and so on. You must always remember that methods such as gymming and exercises may give slow results but they are the safest ways to gain weight. You may gorge on carbohydrate and fat-rich foods like nuts, rice and so on. And to concentrate the fat on the required places, you can consult a gym instructor and perform exercises that can help. And still, if the desired result is not achieved, you can zero on these supplements but only under the medical supervision. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Suzana Zharri, General & Family Physician
