The big one that won't grow antlers is SALT or Sodium content- read your ingredients on ANYTHING, you'll see some are just big bags of salt. Deer need and crave it but doesn't grow the antlers- salt is also helpful to attract for photos.
If you're putting down stuff with Calcium, Phosphorus, etc- those are all going to be beneficial. I would guess MOST of the mineral you could buy will have those. There's also lots of other ingredients (some are trace minerals) that help in areas like: general health, milk quality for fawns, parasite resistance, etc, etc, etc. If you give bucks general good health, those are all things that will help rack growth too. If a guy put out Phos-8, I have not found anything that can beat it for quality of all the ingredients needed, attraction by deer, rack growth, photos, price, etc. I know it's not the only option and the only good product out there BUT I sure haven't found anything better yet & I have no hidden motivation to say that- it's a mineral I pick up at my local co-op.
