Reta 12mg - Sloooooow Motion

Reta DOES NOT "work" the same as those two and from every indication from previous users it was "RETA IS GREAT!": they had NEVER used either Tirz or Sema. "Why isn't Reta working for me!?": they HAD USED one or the other or both.
I'm one of those weird ones that started with Reta and it only worked for me for about 3-4 weeks. Then it was like a switch was flipped and no matter how high I titrated up over time, it literally did nothing for me but raise my resting heart rate a lot and my HRV went down substantially. The more I read, the more I see how individual responses to these peptides are. That's why it's good for everyone to read advice, but also listen to their body and make individualized choices. Our bodies are marvelously complex and unique machines.

Some of you act like calorie in-calorie out is a magic equation to find the faults in individual behaviors...if that were the case none of us would be on GLP1 or any weight loss drugs


Age does an evil wonder to your metabolism, and a sharp calorie deficit can permanently disfigure your basal metabolic expenditure, as seen by a case study of "fattest fat loser" contestants. Its entirely within the realm of possibility that OPs basal enetgy expenditure is just that low, due to age or other symptoms. It could be thyroid, it could be cushing, or it could be a transient metabolic adjustment due to the sharp deficit.

But umm, GLP1s literally make it so that you can take in less calories more easily and thereby lose weight more easily. So... 🤔

And OP said he is not losing as much as the majority here. And i think we all know the consensus here that retatrutide isnt as strong appetite suppressnt as the first two drugs. It shouldnt be that difficult to consider that glp1 just doesnt work well for some populations.

I am sort on the same boat as OP, then again I have low testosterone and hashimotos, two chronic conditions that really cripple overall metabolism. Idk what OP has.

And I would bet good money that if calories were further reduced, then more weight would drop off. But I do believe you’re quite correct about less appetite suppression with Reta - which makes it easier to unknowingly take in more calories.

That's still CICO... if you reduce CO for whatever reason/excuse, you've gotta adjust CI if you want to lose fat. Health issues can suppress metabolic rate ,make you hungrier, make you retain water, but they can not rewrite thermodynamics.

Hashimoto's and low T are remarkably easy thing to treat, for most dudes.
 
First part first - personal Specs



44 year old Male: Moderately handsome, but not dashing



Current weight: 278



Starting weight in Feb 2026: 295



Exercise: weights 3 times a week if I find the time. During my lunch break I walk approximately 2.5 miles as fast as I can. Usually in like 35 to 40 minutes.



Calories: counted via cronometer. Current at 1950 per day.



Reality:



I think I'm a slow responder. I'm currently at 12mg of reta and .75 of cag per week. My weight has been hanging around 280 for a month or so. I can still eat, although less, but still get hungry. If I drop down to 1500 calories I get HUNGRY.



So what gives? Do I increase the reta above the trial limit of 12mg or add more cag? Wait it out? Has anyone stalled at the apex of their dosing?
18 lbs in 3 months , including initial water weight loss of 5-10 lbs is not great. It is very unlikely to truly be a stall this early, more likely just fluid balance variations, but the overall rate of weight loss over 3 months on above standard doses/combo GLP's is not great, it does suggest you are not responding very well given 12mg reta plus 0.75 of cagri. Usually actually stalling takes about a year or so. If it is just slow at say 18-5lbs/3 months or 4 lbs a month and starts going down again at some point it might be fine, just slow.
Pretty sure you said minimal side effects. Do not know height so hard to know how overweight you are, generally the more overweight the faster the weight loss. I assume you did not have diabetes before you started, as that usually reduces the weight loss quite a bit.

Worth getting a different reta batch to exclude a dodgy reta just to be sure.

My guess is the calorie count is a bit off, just because people in general are very inaccurate at calorie counting, you would have to weigh absolutely everything you ate to get it accurate, but if the drugs were working as they should, it should drop your appetite so you have a calorie deficit without any special effort. I think 3 months is too early for significant metabolic adaptation.

If protein intake is not at least 1.5g/kg body weight it should be increased and consider going higher, protein is more satiating per calorie than anything else and you get a bonus 20% extra calories from the energy wasted in metabolising the protein.

Options are - more cagri is probably easiest as you are already on it, or more reta. Depends on what effect adding the cagri had when you started it , if it did not seem to do anything then maybe you are not that responsive to it as well, I can definitely tell I have taken 0.25mg of it. I have seen very few people on high doses of reta on this forum, and obviously it is not been studied medically yet, so it is harder to say for reta how risky high doses are. And the other factor is - is the obesity severe enough to justify whatever the unknown extra risks are of high dose/combo therapy? My thinking is severe obesity BMI 40+ is so bad for your health that any possible risks from experimental combinations or higher doses are almost certainly going to be lower than the risks of the obesity, but this logic breaks down a bit as the obesity gets less severe.

It actually might be worth trying to add in some tirz at not huge doses like 5mg/w, it has the strongest effect on GIP receptors of all the GLP's, and its biased agonism on glp-1 might increase the effects on that as well, given the relative lack of response to reta it might make more sense than increasing the reta dose.

Even adding in semaglutide might be worth considering , but only if tirz did not work, at least it has actually been studied at much higher doses of 7.2mg and 16mg.

What is really needed are studies on what to do if glp therapy does not work or is only marginally effective, there will get done eventually but have not been done yet.

My thinking might be a bit biased towards that combination as it works for me tirz15mg/reta5mg/cagri0.5mg per week, but i lost most of the weight before starting any of them and am using it to try to keep off 55% of my body weight, and definitely respond more to these drugs than you seem to.

You might just be really unlucky and be one of the 5-10% of people who respond poorly to GLP's, but you would need to give it at least another 2 -3 months, and higher doses/combos before deciding that.

I'm thinking about just switch to tirz after reading all the comments here. Weight loss for me has been an excruciating game with little pay off regardless of what I do it seems. I might just be this regardless.

Also I'm 5'11"

You are eating way more than you think you are. That is almost always what this comes down to.

Even when using their little phone apps, people are notorious for underestimating or under-inputting their calorie intake.

You might want to switch from Reta to Tirz, or even add Tirz.

Also, weight lifting and walking are good things to do, but when it comes to energy expediture, both of them are still on the lower end. You could try getting into running or biking.

According to the studies that have been done on Reta, youre likely already exceeding the effective dosing range. The efficacy really peaked around 8-9mpg. You're likely running into a different road block that Reta cannot deal with. Personally, I'd be looking elsewhere instead of going up on the dose.

Incline walking is perhaps the lowest perceived exertion way of burning the most calories.

Efficacy did not peak at 8-9mg.

Yes, it literally did.

When you consider the goal of these medications is to utilize the LEAST amount of medication to get the MOST benefit, most effective dose was 8-9mg. After 9mg you reach what are referred to as "diminishing returns". We use the same model in engine tuning for ignition timing. Its called MBT. You reach a value where the gain in power (the loss of weight here) begins to decline sharply with each additional degree of timing (higher dose).
 
Maybe I just got a bad batch? Like I've said it's from a place highly coveted here that I can't mention so who knows? They also test really well, but I didn't get mine tested.

The sema I took before felt like a gut punch. It didn't really make me lose a lot, but I was only on it 2 months before switching to reta, but it felt like it might lol?

Doctor checks thyroid every time I visit and she gives me the okay every time. Testosterone has been checked and is good. Extensive blood panels came back squeaky clean. So what gives? Maybe this... Lexapro. As I've mentioned before I'm off of it now after several years, but this is a fresh break, maybe by a couple weeks. Previous ssri use during my teens helped me gain about 70 so pounds and upon quitting melted off. Perhaps this is the culprit?

In addition, I'm thinking of going through triz route through the same place just out of ease of ordering. If I do so, what should be my starting dose?

Why wouldn't you be able to mention it here?

There are literal China vendors posting and promoting themselves here, vendor reviews, vendor discussions, etc.

This is glp1forum, not Reddit, after all 😛

That said, different batches from different vendors (or even from the same one!) will be, well, different. Some will be underfilled, some overfilled, etc. There even were examples where R20 was found to actually be R10, and also where zero actual peptides were present in tested vials. So there is that too.

It might be a good idea to get a kit or two from at least two other vendors, and compare the effects.

Have you gotten your labs done? A full hormone and thyroid panel?

Would like to know what your Total Testosterone, Free Tesosterone, SHBG and E2 values look like.

Would also like to know what your insulin resistance and IGF-1 markers are looking like.

Additionally Inflammation markers like CRP and ESR.

You also want to know what your thyroid levels are; TSH, Free t4, Free t3 and reverse T3.

12mg of reta is a high starting dose, and if that isn't working, I would suspect some other things going on internally.
 
...But it's BFF.

😯😯😯😯

Bff isn't infallible, but it's rare to have meaningful issues. I cracked another R60 from him last night.


Did you start tracking calories more? My weight loss over the last month or so has been a bit funky, but I mainly blame complacency.

Oh, I've been a mess with counting. I actually just order some triz because I think I need the extra appetite suppression. We'll see how it goes. Wish me luck.
 
My BFF reta is working, They seem to have a pretty good track record. I did have mine tested though before pinning. I'm down 30 lb in 3 months, 1800 calories a day, current weight of 282, 46 years old. I am meticulous about counting calories and probably overestimate what I'm eating just to be safe If I'm not able to measure it. I'm not extremely active outside of work however at work I stay very active and I am on my feet all day as I manage a restaurant. There's so many variables We all respond so differently so hard to pinpoint one thing. I am in the camp of less is more when it comes to the medicine.

While not as comprehensive as what you've suggested, I just had my labs done within the last month and they came out looking better than ever (triglycerides were stunning for the first time in my adult life). Because of this my doctor doesn't think there would be an issue with anything else. Maybe there is, but I'm just glad that I'm at where I'm at.

Also 12mg was NOT my starting dose. I worked my way up and to be honest I don't feel nearly any of the symptoms people have reported. but on 2.4 of sema I felt like I was being psychically sent to hell, so who knows?

It also has to do with the red banner under your that says "No Source Discussion."

See above about getting flagged. I have a 10 kits from BFF, all with good tests and volume.

Fair enough.

...and there it is, source discussion in the same reply reminding not to discuss the sources 😉

Not being mean, just amused 😁
 
Start BMI was 41 , which is relevant, as I am not sure that high dose combo options are necessarily a safe option unless the obesity is bad enough to have such terrible health risks, that the risks of treatment are almost certainly going to be lower.

The way I see it is, calories in obviously matter, but the whole point of these drugs is to reduce appetite so that when you eat as much as your body is telling you to eat, you are in a calorie deficit, and then lose weight. Trying to force a calorie deficit by cognitive control over eating can work short term, but I think it really does not work long term. The aim with the drugs is to get enough appetite suppression to cause weight loss. Th only food/diet based strategy that might be viable long term are restricting types of foods not amounts, like more lower calorific density foods, and avoiding higher calorific density foods and highly rewarding/addictive foods / high glycaemic index carbs.

Given that it sounds like you are relatively insensitive to the weight loss effects of reta at least and maybe cagri as well, although you are losing weight, just fairly slowly. I would suggest adding tirz rather than swapping. I would be surprised if swapping to standard max dose tirz was more effective than 12mg of reta, not impossible, but not super likely. But adding in a few mg of tirz and building it up a bit to 5 or even 10mg on top of reta might be worth trying. It is mainly just using them at higher doses, as they are not that different, but tirz is the strongest on GIP receptors, which might help. If you found tirz worked better than expected you could then try increasing it and decreasing reta.

I did it the other way around tirz was so much better than ozempic , with minimal side effects and I did not want to risk messing that up, but I was still pretty hungry on 15mg , and added a bit of reta at 5mg/w, which helped.

The other option would be to try eloralintide, instead of cagri, it is both more effective and has less side effects than cagri, the biggest problem would be price, if you are fairly insensitive to it, and need higher doses, it would not be cheap at 9mg /w. I think it is about 2-300 usd /100mg, or that much for about 10 weeks.

I like the way you describe the intent/point of the drugs. Really clearly illustrates why they should work in a way I hadn't read before. Good points here!
