Just interested in other’s experiences really.

  1. What jab and what dose and how long have you been taking it?
  2. Side effects and how and when they show up through the week
  3. Hunger suppression through the week

Heres mine!

  1. MJ since End April, currently 5mg
  2. Side effects - Jab day - sometimes tired depending on time I take it, day 2 - freezing cold, super tired and often a headache, same on day 3 but less, often fine by day 4. Constipation all week long!!
  3. Hunger suppression - Jab day not much depending on time of jab, day 2-4 good suppression, not much hunger and great impulse control. Day 5-7 definitely more pangs of hunger but still feel full after much less food, less impulse control.

I'm on a maintenance dose of about 3.3 mg (40 clicks). Suppression is best day 3-5, but generally have less desire to snack, and I enjoy my meals through out. I luckily don't have any symptoms, apart from occasional constipation when I was on 5mg. Never went above 5mg.

1.What jab and what dose and how long have you been taking it?
Mounjaro, since start of July 2024, 12.5mg currently.

2.Side effects and how and when they show up through the week
None. Well, I'm always cold but that is a constant and it is just how I am now.

3.Hunger suppression through the week
Pretty level, suppression a bit higher in the 2 to 3 days following the injection. I am full quickly, don't think about food much. Doesn't feel like it wears off much over the course of the week.

I was mostly the same pattern as you describe when in my weight loss phase - I got up to 7.5mg but only stayed on that for a couple of months before dropping back down to a 2.5mg maintenance dose. I always made sure to drink at least 2L water to stave off any headache (if I aim for 3L, I usually manage 2!!) It's become a habit now, I have a massive stanley cup with a straw on my desk and just sip away all day as I work.

For the constipation, drinking water, 2Tbsp chia seeds and berries with my yoghurt every morning, really prioritising fibre/fruit/veg in every meal, getting at least 10k steps walking, and ideally some other exercise on top as well (I started lifting weights and doing barre when on MJ, so I have actually gained muscle on MJ not lost it).

Lost the weight 2+ years ago but still do the above as I tried hard to make them habitual lifestyle changes, rather than just dealing with side effects.

1 MJ from May 2025 went up to 10 mg
2 side effects were tiredness, sensitive skin, eventually some hair thinning, feeling cold.
3 I injected just before bedtime so day one was hungry, two to five no hunger and good suppression, day 6 a little less effective, day 7 less suppression, hungry.

Total weight lost 51 kg now maintaining on wegovy pill - no side effects now and nice even suppression .

I’m on 5mg maintenance of mounjaro, have been for over 18 months, suppression is at the same level throughout fhe week, max dose in weight loss was 10mg, for the majority of it. No side effects,

  1. What jab and what dose and how long have you been taking it?
    Have been on MJ since Oct 2025 and just reached maintenance, 6 months on 2.5mg and then 6 months on 3.75mg. Moving down to 3mg from my next jab for maintenance.

  2. Side effects and how and when they show up through the week
    Very minimal side effects the whole time, a bit of constipation which I manage well with magnesium tablets and psyllium husk tablets, plus getting all my daily fibre in!

  3. Hunger suppression through the week
    I eat 3 meals a day, and a snack. I had suppression for a couple of months initially but now I just eat normally, but healthily.

What jab and what dose and how long have you been taking it?
Mounjaro, started Jan 26, 7.5mg at the moment but about to increase to lose the last 1.5 stone.
2.Side effects and how and when they show up through the week
Nothing major, just tiredness on jab day and the day after. Some constipation but not for more than 48 hours.
3.Hunger suppression through the week, Suppression is strong from 12 hours after jabbing until the day before the next jab. I have noticed this is getting less which is why I am planning to move up to 8.75. I can eat breakfast and lunch but struggle to finish evening meals.

Thanks all - interesting to see some have consistent effects and some get a lot hungrier (like me) towards the end of the week…

Mounjaro, 5mg, 22 months

Side effects and how and when they show up through the week

Zero. Well, I have had diarrhoea twice since starting, once was almost certainly down to stress and the other may have been related to the jab but I cannot pin point and trigger food or mood so I’m not convinced it wasn’t just a run of the mill tummy bug.

Hunger suppression through the week

I don’t really have suppression as such, I don’t eat like a pig or binge anymore but I still feel ginger and eat full and proper meals. I did struggle at the start to eat enough as the suppression for the first few weeks was insane. I almost stopped because of it. I need to feel ‘normal’ things, and being hungry, having an appetite are normal. I think MJ takes the edge off and stops me eating too much but it hadn’t stopped me eating well. I have lost 10 stone.
