Wouldn't dosing once at the start of the week and once at the end technically land on the same day again eventually? Ha.
Plenty of people around here inject twice weekly, more commonly landing on day three and day seven or thereabouts. Goes by the name split dosing, and it keeps drug levels steadier overall. Some claim it holds food noise at bay more consistently and eases side effects too.
Never tried splitting mine personally, mostly because early on I came across something suggesting it was less effective, though I'm not fully convinced that's actually true. Just kind of lodged itself in my head like a myth that won't shake loose. I stick with one weekly shot purely for simplicity.
