The single bottle. Not because the larger packs are a trap, but because of two
dates.
The window is of unknown length
The packaging carries a money-back seal and the supplied pack says the guarantee is
“as printed on the listing”, adding that this is often the marketplace return
window. No number of days is given anywhere in our sources, so we print none. Buying six
bottles inside a window you cannot see the end of is a larger bet than buying one, and
the size of the bet is the part you control. Our
guarantee page takes that apart properly.
The expiry date against 360 capsules
The side panel prints Expiry date: 07-2028. The six-bottle pack is
360 capsules, which at one a day — the bottom of the label’s own range — is
360 days of product from whenever the parcel lands. Check that date on the bottles you
actually receive rather than on artwork.
And a third reason, about you rather than the label: a first bottle answers whether a
daily capsule survives contact with your actual life. At two a day that answer arrives in
thirty days. The saving on a larger pack does not expire. The window does, and you cannot
currently see when.
