To be honest you want to enhance the beef flavor with your injection, a good way to start is to get a knorr stock cube, dilute it and use that. See what you think and then adapt as you see fit. There are several competition injections out there such as butchers but i wouldnt use them at home as they are aimed at the "single bite" competition market and would be a little too much.
