Responsible Practice assessment
Material concerns- · Product pages for semaglutide, tirzepatide and retatrutide prominently quote clinical-trial weight-loss percentages (e.g. 'up to 22.5% of body weight').
- · The site's returns policy text contradicts itself between two pages, in the same pattern found on Platinum Peptides.
