mineral feeds
I would love to use things such as 30-06 mineral supplement, inititate, optimize and sustain but they are just to expensive. The contents are listed as crude protein, calcium, phosphurus etc. My question is if protein is the key for antler development can i buy just protein somewhere and add it to whatever I want? Plain old salt has calcium and phosphurus in it.
Is this stuff that body builders use the same type of protein. Like baseball players use creatine.
