How long till tirzepatide kicks in ymmv

ok so i’ve been reading abt tirzepatide and its effects on weight loss, which is really interesting to me. i’m thinking of trying it out for a shoulder thing too, since i’ve had some luck with bpc-157 in the past.

but how long does it usually take for tirzepatide to start working? is it pretty quick or do i need to give it a few wks?
