<s>[INST] Hey,M 24 Yrs Male. I have average body, I started workout in Gym somewhere around 8 months ago. I hear from a doctor taking Proteins from supplements will cause problem in marriage life. M not married yet. But is it so Will it give any kind of problems in Child productivity? What is the different between Steroieds and other medicine which helps you to gain Size and body weight? Does those medicine contain Steroids?Thanks [/INST] Hello and Welcome to ‘Ask A Doctor’ service.I have reviewed your query and here is my advice.You can check content on protein supplement. Only protein containing supplements are useful because to workout we need protein to replenish lost protein. But steroid containing supplements should not be taken which has hazardous effect on health. So don't worry in taking supplements which only contain protein. I hope I have answered your query. Let me know if you have any further questions. Regards,Dr. Parth Goswami </s>
