Going from 2.5 to 3.75 in MJ gave me a huge spike and bad side effects, so I built a free tool to see it coming
I take partial doses from a 10 mg kwikpen. After about seven weeks on 2.5 mg it had levelled off and I wasn't feeling much anymore, so my doctor and I agreed to go up to 3.75.
That meant 22 clicks, about 3.7 mg. My levels jumped way up and the side effects were rough. Another week at that dose would have pushed them up again by about the same amount.
So we dropped to 20 clicks (3.33 mg). Levels still went up, just a little, and the side effects stayed manageable. That's when it clicked for me that the size of each step up matters as much as where you end up.
I wanted an easy way to plan doses like that and see the jumps before I take them. A lot of you probably use the plotter on glapp. Mine uses the same maths, but I found glapp's fiddly to use, especially for planning in clicks, so I built my own:

You put in your plan, in mg or in clicks from your pen, and it draws your estimated levels over time. It also tracks how many clicks you have left in each pen. It's free, there's no sign-up, and it works on your phone.
It's helped me a lot and I hope it helps some of you too. It's an estimate, not medical advice, so talk changes through with your doctor like I did. Feedback is very welcome - Ive mostly tested only for Mounjaro.
