Just got this response from the ASA:
"YOUR COMPLAINT ABOUT PROTEIN WORLD LTD - A15-300888
Thank you for contacting the ASA and for your patience so far.
We have received a number of complaints about these ads raising issues similar to the concerns you have expressed, as well as a number of different issues. We are still in the process of making a thorough assessment of all of the complaints we have received and are considering how best to address the concerns that have been raised. To that end, we will be meeting with the advertiser as soon as possible to discuss their advertising generally and these ads in particular. When I have more information following this meeting, I will contact you to advise of any action we may be taking.
We very much appreciate your continued patience in the meantime.
Yours sincerely
Emma Smith
Senior Complaints Executive"
