Dosing schedule disaster! Advice needed!

Hoping for some guidance and shared stories here... I had great success with brand-name semaglutide back in 2024 and early 2025, but my access stopped in May. I was at 2.4mg then. Finished what I had in July. Talked to my doctor in August about options, and he's okay with me paying out of pocket for either sema or tirz. I'm a T2 diabetic.

I decided to go with "research supply" sema because I knew it better. Tirz was an unknown. Less variables felt safer to start. Began testing in September, starting at 0.25mg and working up to 2.4mg. From September to late November, scale didn't budge.

Then, in late November, I added 0.1mg of cagrilintide. Kept that going with the 2.4mg sema. Lost about 2 pounds between 11/25 and 12/10. We've been traveling since 12/12.

Here's where I messed up: I didn't pack my sema! Took a partial dose last Wednesday, plus the cagri. Nothing yesterday. Getting home tomorrow (Friday). Not sure what to do. Did I mess up the sema by missing a dose? Should I take 2.4mg sema tomorrow and cagri on Saturday (or Sunday), even though it wasn't really working? Or should I just take a break for 5-6 weeks, let it clear out, and start tirzepatide at 2.5mg in February?

I've also seen some stuff about new sema dosing info coming out...

Mostly, I'm worried about messing up my receptors. If I need to avoid testing for a while to be safe, I will. Nothing's worth risking my health. Six years ago, I was very overweight and had T2 diabetes, fatty liver, sleep apnea, and high cholesterol.

Now, I'm almost half the size, my liver's healthy, sleep apnea's gone, and my cholesterol and blood pressure are great. T2 in remission. Just need to lose these last 20-ish pounds. I've never been healthier.

I'm stuck. Any advice is welcome. There's so much collective wisdom here. I'm still learning. Thanks for reading!
 
As far as I know, there's not much evidence that GLP-1 meds mess with your receptors. And you probably don't need a long washout period, especially since you're using the meds to help manage your blood sugar. Letting your glucose levels spike for weeks isn't ideal. There's some evidence of tolerance to side effects like nausea, which tends to improve. Gastric emptying also normalizes a bit over time. But there's no proof of tolerance to their effects on blood sugar, appetite, or weight loss for at least 3 years. Long-term studies are still needed.

Tirzepatide is better at controlling blood sugar and causing weight loss. It's also often easier to tolerate, with less nausea. Since you're at a point where you want more weight loss and aren't getting it from max-dose semaglutide, switching to tirzepatide makes sense. I don't think you need a washout. Since you tolerate 2.4mg of semaglutide, you could likely start at 5mg of tirzepatide safely, with minimal chances of worse side effects. Without knowing your other meds, I can't recommend increasing doses faster than normal. But if you're not on other meds and your blood sugar is high, you could increase doses quicker. Otherwise, increase every 4 weeks if glucose levels are okay.

Continuing cagrilintide is up to you. The only reason not to would be hypoglycemia or difficulty figuring out which drug is causing the effects. Tirzepatide alone is backed by science for weight loss and diabetes. The sema/cagri combo isn't as well-studied, since cagri isn't approved yet. But there's no reason to think it's dangerous. And studies of the combo have been successful, although I think tirzepatide was slightly better for weight loss.
 
I wouldn't 'reset.' Jump straight to tirz. Amazing results. It seems like we reach a limit with each of these drugs, even with something like adding cagri.
 
Yeah, I'd switch to Tirz next. Good explanation from ThinLizzie. Maybe keep some Sema around in case you wanna stack 'em later for more appetite control. Cagri is good for that too! (Cagri gives me a nice energy boost, but some people get tired from it). Good luck, you can't really mess this up.
 
Thanks, everyone, for the quick replies. Luckily, my T2 is in remission, so I don't need the GLP-1s to manage it daily. Over time, my A1C does start to creep up, even with my usual diet and exercise. So, I'm using the GLP-1s as a protective measure for managing glucose related to the T2. My A1C was fine before the GLP-1s because I was doing diet and exercise. It hasn't dropped much since starting them, actually.

Thanks for the feedback about receptor clearing. I've seen anecdotal stuff saying it takes longer to get benefits when you stop and restart GLP-1s. Glad to hear that's probably not true.

Tirz it is, then. To keep things simple, I won't dose two products at once unless I need to reconsider Cagri later.

The info I saw also said Cagri helps with diabetes management.

Thanks again! This decision-making is a pain.
 
I agree with meal-prep-pro... Might as well switch over to Tirz. It sounds like your body has adjusted to the sema.

I've heard about people staying on low doses of sema successfully for a while, so that's an option too. Saw someone online say they "stayed on 0.5 for about a year, and I have gone down to 0.25 for the last few months! It’s been slow but it feels good knowing it will likely be easier to sustain long term."
 
Just a heads-up based on what ThinLizzie said: tirzepatide is a dual GIP and GLP-1 receptor agonist, while semaglutide is *only* a GLP-1 receptor agonist. That difference in mechanism is why many find tirzepatide more effective. Something to keep in mind as you transition, CoolMom559.
 
Started October down 30. Try to stick to trial schedule. Just hit 8 rough. Burning burps and bad issues. Splitting to 4 twice a week this week.
