Hello there. I can understand that you want to build body and would go to any extent to do so. Who has put in your mind that you need to take steroid and testosterone injections for it? Do you know the side effects of such practices? I would never suggest you or any one for that matter such things. High protein diet along with whey protein supplement should be enough. Eggs and milk recommended. You can take upto 6 eggs a day. Kindly do not indulge in such unhealthy practices or the consequences can be severe. Best regards. Dr. Anil Kumar Jain.
