Stairmaster1's reasons for banning sound sound, if true. But I don't see the issue if several brand-fronts / people are in fact the same operation. We know we're not dealing with Boy Scouts or state-licensed pharmacists or Marcus Welby, MD. The market is grey; we just want (and should expect) safety, effectiveness and whatever value for money we signed up for.
In marketing terms, what they're doing (if people's guesses about it are correct) is different brand positioning for the same product. Chrysler and Plymouth put different badges on the same car. PayPal and Venmo (same ownership) do more or less the same thing, with their own bells and whistles. Google Maps and Waze. Mounjaro and Zepbound; the other two too.
Now I have to make it my business to learn who/what Stairmaster1 is, and how it will help me make my first tirz peptide purchase. After the Chinese New Year.
