Carnosine alternatives?

According to a source that may have some commercial members (and places an ad for carosine in its leading illustration), carnosine can extend life. Carnosine protects against glycation, which causes loss of elasticity. Older persons loose carnosine, so supplements may extend their life. As a person who has an ethical dispreference for eating beef (to minimize the destruction of sapience), I want to live longer and happier while allowing other advanced intelligences to also live longer and happier.

So I have questions. Is carnosine the essential ingredient for humans, compared to anserine or other peptides? Carnosine is found in beef. It strikes me as odd that a useful peptide would only be found in the meat of only one species. Rats (and I would imagine) other species have carnosine in their muscle and brain tissue. Is carnosine efficiently found in other sources? Other mammals, birds, fish? Where do the supplements derive their sources? Would it also be from animal source, and if so, which animal?
