repcal - Beardied dragon Diet

[Geck-co]

Just wondering who all uses this? I was at a store near my house last night and they did not have the juv. diet, only the adult. They did have small pelletted food but it was not specifically for any certain kind of reptile had a pic of a beardie on it but I figure that could just be misleading. I think that stuff was jerassi diet or something like that. When in my original plan I was going to just feed assorted insects and greens. But would like to try this pelleted food out. Is there a difference between the juv. and the adult food that rep cal offers other then just the size? If I where to break the larger pieces up and use them would there be a problem? or are they both formulated differently for the different stages of growth?
