Choosing Between Tirz and Reta for a 54-Year-Old Woman

20 replies17 peopleAug 16, 2026☆ Follow
Summary

Which GLP-1 should a 54-year-old woman with night-time sweet cravings, smoking, ADHD/BPD, and current meds start on?

Participants largely recommend tirzepatide over retatrutide for her modest BMI and profile, citing gentler side effects, strong food-noise reduction for evening snacking, and adequate results without added heart-rate risks. Retatrutide is viewed as potentially faster but overkill or riskier here, with some noting it could be added later if needed. Conservative low starting doses, watching constipation from other meds, and doctor oversight are repeatedly advised.

What this discussion establishesWhere people disagree

Whether retatrutide's faster loss and metabolic edge justify its use from the start versus staying on tirzepatide alone

Still open

How her smoking, anhedonia risk, or cholesterol med will interact long-term with either drug

Nothing here is advice.

Which GLP-1 would you pick for my mom? I know the basics and want input on her full situation. Age 54 female, 5'7", 88 kg now aiming for 70 kg. Blood pressure and heart rate fine, hormones okay after hysterectomy three years ago, never tried any GLP-1 before. She takes escitalopram 10 mg, fenofibrate for LDL, occasional alprazolam and Doreta for back pain. ADHD and BPD diagnosed but untreated. She is somewhat active at work but otherwise sedentary, overeats sweets at night, smokes a pack a day, and drinks four or five coffees. She researched this herself, likes my results, and wants me to decide.

You're thinking along the right lines. Sema is weaker and only worth it for price. Tirz gives very good appetite control and feels milder overall. Both help heart health similarly in non-diabetics, but reta may edge ahead by raising metabolism and hitting fat more directly. I'm on tirz now and dropped 50 lb in five months. Starting reta tomorrow at low dose alongside it for the extra effects, then shifting doses once near goal for maintenance on both.

Tirz tends to have fewer sides and some reports say it quiets food noise better, which could help her night-time sweets. A friend on it still struggles with evening snacking though. As an older woman I like tirz a lot, but if reta had been around when I started I might have gone for the quicker loss it seems to offer. The resting heart rate increase still worries me.

I went with tirzepatide because it matches my goals and is known for stronger food-noise reduction, which could help those late-night cravings. It also leaves room to add reta later if needed. Alprazolam and Ultracet can both worsen constipation, a common GLP-1 issue, so watch that. The other two meds look fine together. I'm male, similar height, started heavier and went well past my goal, so she might too and adjust her target. My vote is tirz.

Everyone points to the studies for a 2 mg reta start, but I began at 0.5 mg and did fine, taking nine months to reach 3 mg. I'm cautious about advising my own mother.

I would personally suggest tirz to her.

Agree. I'm an older female too. Tirz has been great for food noise and inflammation since January. Faster loss isn't always better at our age because skin and hair don't recover as well. It took me eight months to go from 96 kg to 65 kg and I've held there since, a bit under my original goal. Same height as her.

I began at 1.25 tirz. Some GI effects showed up but nothing severe. No one wants to spend the first days dealing with diarrhea or constipation.

True. I started reta at the full 2 mg when I was class 2 obese, so I figured the same for her, but she is only barely class 1. Thanks for the reminder, I'll start her lower before moving up to 2.5 mg. Appreciate all the input, any more thoughts welcome.

GreyHarbour88archiveAug 16

I'm only a bit younger than her. Started on tirz and still recommend it. Added reta later to break a stall, but she may not need to switch since her goal is only about 20 percent loss.

I began tirz at 2.5 mg per the trials, but starting lower is fine if sides or quality are a worry. Others begin small and move up quickly without staying low for a full month. Millions have started at the standard 2.5 mg though.

LevelPebble88archiveAug 16

Reta seems excessive for a BMI around 30. Her situation differs from yours. Tirz might get her all the way there depending on response. If a stall hits, reta could be added later once more available. If it were my mom I'd have her see a doctor first for baseline checks and monitoring, even if using non-branded versions afterward. Hydration matters more for her because of the fenofibrate.

LevelThistle44archiveAug 16

Another vote for the usually gentler tirz over reta. Begin at 2.5 mg and adjust based on how well it works and any sides.

That's exactly what I did. She got doctor approval for Mounjaro but I still wanted forum opinions since reta isn't officially prescribable for her. Thanks to everyone for the replies.

Use tirz and let her doctor know she's on the compounded version. She already has approval for the brand name, so it can go on her chart. Her PCP suggests compounded tirz for cost reasons. Not sure how a doctor would view reta. Tirz might also help her quit smoking.

PatientLedger69archiveAug 16

Reta at 2 mg can hit hard if she isn't very overweight. Tirz would probably be easier for someone new.

I got compounded through my doctor but it cost more, so I switched to other sources. At a recent visit the NP asked if I was still on tirz, I said compounded, and she said she likes compounded.

IronKettle95archiveAug 16

I helped a relative start on the brand name and they split the starting dose twice weekly. Now at 5 mg split the same way with no sides, already down 10 lb and glad they chose a GLP-1.

I just did this for my dad who is 76. Picked tirz because reta can raise heart rate. Reta might suit him better for visceral fat but he has leg swelling and wears compression socks, so I didn't want the risk. Your mom is close to my age and profile except I still have my uterus. I've been on reta eight months with good results. Anhedonia could be an issue but tirz has that too. No real heart-rate or skin-burning problems for me. Reta cut my sweet tooth so I can stop at one cookie. It doesn't curb smoking desire though, and appetite suppression isn't as strong as tirz.

Resting heart rate and the insomnia some call reta-somnia? My sister is on reta, says she's done after this vial and going back to straight tirz. Split dosing didn't help her sides much. I'll take the rest of her kit when I'm ready to try it.

QuietThistle70archiveAug 16

Start her on tirz for the reasons already given. Many telehealth compounding services begin at 1 mg weekly for the first two weeks then move to 2 mg if no problems. That's standard remote advice. Use that unless a doctor is directly involved. If starting reta instead, keep it at 1 mg or even 0.5 mg. Physician oversight is harder to get for reta. She might lower the cholesterol med later, and tirz can help with quitting smoking if she wants.
