Grow and Shine VS Implants

Which has had the best results Grow and shine or the melatonin implants? nowhere on the grow and shine website does it say how much to give per calf per day.

This year I tried the implants.  The previous year I used the Grow and Shine.  I am going back to the Grow and Shine.  It is more time consuming but I saw better results with it.  Off the top of my head I don't recall the dosage but it is listed on the bottle.  Seems it was 1-2 ounces.  I just mixed it in the feed and had no problems with them eating it.
