It's probably worth pointing out peptides of any type are perfectly legal to sell and possess in the US provided they're not labeled or marketed for human consumption. None are controlled substances, and not subject to seizure.
That's why there are dozens of "daylight" US domestic companies able to openly sell them for "non-human research use only" take credit cards, and not be shut down.
That isn't the case elsewhere.
Labeling them as any kind of product subject to FDA regulation would subject them to seizure. So ironically, if the "stealth" label is believed vs what the product actually is, that would create a problem where there wasn't one.
Personally I love these plastic boxes some vendors use for peptides:
