the implants are going to be expensive to, and they are not a 100% guarantee...it all depends on how the calf responds to them...and like everyone else says all the time...you can implant, feed every supplement on the market, pack them in ice if you want...if the genetics are not there they arent going to grow 4" of hair, but amount of hair isnt most important thing, its quality of hair that makes a difference on show day if you ask me...and there is no supplement for quality of hair, the cooler wont even improve hair quality, the only thing that will improve hair quality is work, work, work
