Hi. Total newbie to this group , 1st ever post.
I started 16 days ago. I've had 3 jabs of 2.5mg Mounjaro so far. Zero side effects and zero effects! No appetite suppression whatsoever! They say it's because this is the initiation phase and I need to move up to 5mg for my next order. I've read about the the 5th golden dose (thanks for sharing). There does look like 2 more doses left in the pen too.
Question: should I take a 5th week of 2.5mg ? OR, for jab 4, should I inject 2.5mg and then inject what's left in the pen? Which will probably be a total of 5mg?
Any advice greatly appreciated.
Thanks.

Take your 4th dose as normal. Guidelines recommend that you stick on a dose for the full 4 weeks before moving up, to allow your body to become used to the medicine.
Then on week 5, you will see that there should be a bit more than one full dose left in the pen.
Most people are managing to get out the equivalent of a 3.75mg dose. This is a nice inbetween step before moving up to 5mg.

Edited to add - do not take your 4th dose AND the 5th dose on the same week - you will possibly end up jumping from 2.5mg to around 6mg after only 3 weeks of 2.5mg. I don't think that is sensible.

you should not increase on dose 4 as there is a loading schedule for a reason and it’s accumulating in your system week by week.

if you take a normal dose 4, then extract the 5th dose the following week very carefully you should get a bit of a step up - probably 3.75 at most (0.9ml). Or if you want to get straight up to 5 just start the next pen.
