When did you all move up with MJ?

I'm very curious to see how common it is to move through the doses every 4 weeks until you get to the maximum dose?

I'm on the most wonderful group and we all started at the same time, but I'd say the vast majority are on a lower dose than 'the schedule' - and they all seem to be doing amazingly with their weightloss too.

Do people tend to stick to certain doses for several months? I've not had much success with 2.5mg and 5mg but early indications are 7.5mg is effective. Assume I'm good to stay on an effective dose until I need to move up?

I swap providers each month but they all say you can stay on current dose of it's working well.

I did 5 weeks on 2.5, 2 weeks on 3.75 and I think I'm about to start my 8th week on 5mg so I'm definitely moving up slower than I'm "meant" to but I'm happy on 5mg so don't want to rush up the doses as also I have alot of weight to lose so worried that if I go up to soon I'll get to the max and still have lots of weight to go so I want to save th higher doses for when I really need them

Ps I'm 23 pound down in 14 weeks

MadamTeapot · 29/06/2025 19:26

I only went up to 10mg, 2.5 and 5 were fine and looking back I should have stayed at 5. 7.5 gave me v little suppression but 10 was much better. I plan to stay at 10 for a further 12 months then drop down very slowly. I’ve lost six stones, but incorporated huge lifestyle changes (diet and exercise are hugely different to old me).

I did 4 weeks on 2.5mg, lost a lot of weight, moved up to 5mg really because that was the schedule and not because I felt I needed to. Had some side effects, but had already got a a 7.5mg pen, so did 5mg from it for 2 weeks, then a 6.25mg dose before doing a 7.5mg dose. Then I stayed on 7.5mg for several months as it was working consistently well for me with no side effects. I’ve only recently gone up to 10mg as my weight loss had slowed and the 7.5mg was beginning to feel like it wasn’t doing much. I will stay on 10mg, as it’s also now working well for me without any side effects.

According to the standard schedule I “should” have been on 15mg for months now, if I’d moved up every 4 weeks.

5 weeks at 2.5mg. Thought I had to move up, but was a bit nervous so did 3.75mg and stuck with that for the last 48 weeks! Works for me.

How long others stay on doses is not really relevant to you and what you do, so try not to worry about maybe doing it wrong.

You need to think about what approach you want to take and what your expectations are from the medication. Some want strong suppression and move up the doses quickly, others are happy with just food noise dialled down and get that with the lower doses, others need to move up just to get the food noise removed, others are different again. We all need to walk our own paths.

I did 5 weeks of 2.5, then a single 2.9, 2 weeks of 3.33, then I think 5-6 weeks of 3.75. I have been on 5mg for 6 weeks now. I suspect I might need to go up after this pen, but will do 6.25 for as long as possible. Doing this I am controlling my weight loss to not lose too fast, and have avoided getting side effects. I also want to take as smaller dose as possible, but as much as I need for it to work.

SubDoserIV · 29/06/2025 20:16

I struggled going up from 2.5 mg to 5 mg with side effects (bolded weeks) - then I was a bit over cautious! In hindsight I should have stuck at 4.2 mg the first time or reduced to 3.75 mg as I was over suppressed. I thought I was being cautious taking the bonus and the going up in increments though at the time. 13.75 mg working well now, but I expect to go up to 15 mg fairly soon.

I move up when the suppression is wearing off and the cravings are back. I also use all the liquid in each pen so do 5 doses (although have bridged a few pens, so used the leftover and then topped up with the new pen to get a higher dose). So far I've done 5 weeks of 2.5mg, 4 weeks of 5mg, 10 weeks of 7.5mg, 12 weeks of 10mg and continuing with 10 (sometimes the fifth dose is slightly higher though, so every 5 weeks I get mega suppression on the ten-pen!)

Week 17 and still on 2.5, current weight loss 3 stone.

ThisCyanPoet · 30/06/2025 02:03

I moved up to 5mg a couple of weeks ago and feel horrific. I can’t stand the sight of food and am feeling really tired and weak. Going back down to 2.5mg when I next order. I don’t know why I went up, as food noise was gone with the 2.5 so I should have stayed with it. I’ve lost a stone in six weeks, so am really happy with that.

IReallyNeedThisToWork · 30/06/2025 19:49

I did 4 weeks on 2.5, 20 on 5mg, 9 on 7.5 and am about 20 or so weeks into 10 (had a random 2 weeks on 12.5 to push to goal. Hated it! 😂)

Got my last 10mg pen to stabilise and then will start trying to drop down 🤞

ThinkingaboutMJ · 30/06/2025 19:54

I'm still on 2.5 (2nd pen) and will for my third too. I get a good level of suppression and feeling full after eating smaller portions. I do feel hungry on occasion but I'm ok with that because it means I get into more normal patterns for eventually coming off. I'm just over a month in (first jab was May 27th) and hit a stone loss today! I will increase if this stops being effective but I'm in no hurry. I get no side effects and I'd like it to stay that way.

I haven’t moved up at all. 7 months and 5 and a half stone down, all on 2.5mg

MJMabel · 30/06/2025 22:31

I haven’t moved up either, three and a half months in, all on 2.5mg. I have four weeks’ worth of 3.5mg left and will then go up to 5mg.

MJMabel · 30/06/2025 22:32

2.5 not 3.5!
