Nice job by RVNC CEO, Dan Browne at Barclays today; from #msg-129290320:
...RT002 is a more modern and much purer product than Botox. Specifically, RT002 has no animal-derived ingredients and no excipients other than the proprietary peptide (for reduced diffusion from the injection site). Botox, on the other hand, uses human albumin and other stabilizing proteins in its formulation, which has remained essentially unchanged since the 1980s.
Browne remembered to stress this point on today's webcast.
