left is a protein that bears some resemblance to rhino keratin and it doesn't look like yeast which was what was used to make the bio- neared rhino horn there is keratin there. it is a crude form of it. there's more refinement that need to be done. they're not there yet, but they're going in the right direction. >> reporter: according to the final lab report, the company sample contained high levels of calcium aattributed to large quantities of preservatives obviously not found in the real rhino horn. we reached out to the company for comment. they responded that the high leflts of calcium why-- levels of calcium were in keeping with the real horn. while they acknowledged the presence of some preservatives, they says "they're just part of the prototype process and won't be in the horn when we are at the pilot plant scale". only time will tell if they have cracked the code in creating the horn that is 100% bio- identical to the same thing. my fingernails are currently still a closer match, begging the question, if taking rhino horn powder is essentially the same as chewing on your fingernails could users be persuaded to just say no? up
