Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Yes more protein powder and amino acid can cause such a problem. Because of increase load of protein you are facing indigestion. I advice you to lower down the protein to extent which is digestive to you. Most powders are associated with androgenic hormone if you are having more of hormones. If its with your supplement your muscle mass will increase with it. But simultaneously other side effects like your face becones coarse, change in voice, fluid retention all increases. I advice not to take the protein supplements they are total waste. You can increase your bulk with good protien diet like meat, milk, soyabean etc. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
