"How to use the product" can mean a couple of different things. Nonetheless, if the video is about the sponsor's product, the advertising provisions would appear to apply (in which case, in the non-gated context you've described, the video would be subject to section C.01.044 for the Food and Drug Regulations if it relates to an Rx product). Discussion of the how/who/when/where/why relating to administration/use of the product would appear to be in excess of the name, price, and quantity restriction. Note that this is not a PAAB code issue. It is an opinion based on PAAB's interpretation of the Food and Drug Regulations.
