Different uses for Purina High Octaine supplements?

[Mcabram]

Can anyone define what each supplement does for show steers? I have a few of them readily available through my chapter but I do not know what they do individually. I have a steer that is 1000 lbs, his fair is in early March, and I would like some muscle definition and top shape on him.
Thank you in advance!

Champion drive is the purina supplement you want for what you described you wanted to improve on your steer
