Wegovy or Mounjaro —
how an internal-medicine clinic in Cheongdam chooses.
Wegovy acts on one hormone pathway; Mounjaro acts on two and steps through more dose stages, which allows a gentler ramp. Both are weekly self-injections, both carry the same class of gastrointestinal side effects, and neither is prescribed at ARTNER Cheongdam, Gangnam without an in-person assessment showing BMI 30 and above, or 27 with a weight-related condition. The choice is made on history and tolerance, not on price or popularity.
These two medicines are discussed online as though one is simply stronger than the other. In practice the choice is clinical: what you have tolerated before, what else you take, how quickly you need to titrate, and what your history shows. Here is how ARTNER Cheongdam, Gangnam actually decides — and the eligibility rule that comes before the choice.
You have decided you want a GLP-1 and are choosing between two.
- You have read that Mounjaro is more effective and want that one.
- You had nausea on one and want to know if the other is gentler.
- You take other medication and are unsure about interactions.
- You are travelling to Korea and want a prescription arranged first.
- You want to know which is cheaper.
Eligibility comes before the choice, and the choice is made at the visit. One of the five above has an answer of no — remote prescribing is not permitted in Korea.

What the mechanisms actually differ in
After eating, the gut releases hormones — GLP-1 and GIP — that signal fullness and slow gastric emptying. Semaglutide (Wegovy) mimics GLP-1. Tirzepatide (Mounjaro) acts on both GIP and GLP-1.
The practical consequence of dual action is a broader effect on appetite signalling and, in clinical use, a finer set of dose steps to move through. Whether that translates to a better outcome for you specifically depends on tolerance, adherence and eating patterns, not on the mechanism alone.
How Dr. Pyeon chooses between them in Cheongdam
Previous response. If you have taken one before and tolerated it well, that is a strong argument for continuing. If you had significant nausea, the finer titration steps of the other may be the answer. Other medications. Interactions and gastrointestinal history matter more than marketing claims.
The pace you need. A slower ramp costs time but reduces side effects. As an internal-medicine specialist, Dr. Pyeon titrates conservatively rather than pushing to the top dose because it exists.
Eligibility comes before the choice
Korean criteria are BMI 30 and above, or 27 and above with a weight-related condition such as hypertension, dyslipidaemia, prediabetes or sleep apnoea — confirmed with measured height and weight, InBody and history at the visit.
It is not prescribed for cosmetic weight loss at a healthy weight, whichever medication you ask for. If your weight is fine and one area bothers you, that is a contouring question rather than a prescription one.

Side effects — the honest version
Both belong to the same class and share its effects: nausea, reduced appetite, constipation or diarrhoea, strongest early and easing as the dose is titrated slowly. Less common effects are discussed individually at assessment in Gangnam.
The management is the same for both: titrate more slowly rather than pushing through symptoms. Most people who abandon these medications did so because someone escalated the dose too fast.
What neither one will do for you
Neither chooses where fat leaves. Body weight and visceral fat fall; a stubborn pinchable pocket usually stays, because that is a local deposit rather than a systemic one.
And neither is a substitute for eating and activity changes — weight regain is common on stopping if patterns return to baseline. ARTNER Cheongdam plans the medication alongside those changes precisely so the result holds.
Weight first, then contouring: visceral vs subcutaneous fat.
Cost, and why it is quoted at assessment
Both are quoted after the in-person visit at ARTNER Cheongdam, because the medication, dose stage and duration are all clinical decisions rather than menu items. The quote is given in KRW, excludes VAT and matches the Korean price list.
Price should not decide which molecule goes into you. If a clinic leads with the cheaper one before examining you, that is a sales sequence rather than a clinical one.
In short — Wegovy acts on GLP-1; Mounjaro acts on GIP and GLP-1 with finer dose steps. ARTNER Cheongdam, Gangnam chooses between them on previous response, other medications, gastrointestinal history and the titration pace you need — after confirming eligibility in person at BMI 30+, or 27+ with a weight-related condition.

Patients arrive having decided which one they want from the internet. My job is to check whether either is appropriate first, and then to pick the one their history points to — usually the one they will still be taking in three months.

Compared honestly at ARTNER Cheongdam, Gangnam.
Wegovy (semaglutide) acts on the GLP-1 pathway; Mounjaro (tirzepatide) acts on both GIP and GLP-1 and steps through more dose stages, allowing a gentler ramp. Both are weekly self-injections.
Neither universally. ARTNER Cheongdam chooses on previous response, other medications, gastrointestinal history and how quickly you need to titrate — not on marketing or price.
Korean criteria are BMI 30 and above, or 27 and above with a weight-related condition, confirmed in person with measurement, InBody and history at ARTNER Cheongdam, Gangnam.
No. Korean regulation requires an in-person consultation, so the first prescription is issued at your visit to Cheongdam — never remotely.
Possibly. Finer dose steps allow a slower ramp, which is the main lever for side effects. The management for both is to titrate slowly rather than push through symptoms.
Both are quoted after the in-person assessment, because medication, dose stage and duration are clinical decisions. Price should not decide which molecule you take.
Neither chooses where fat leaves. Both reduce body weight and visceral fat; a stubborn pinchable pocket usually remains and is a contouring question afterwards.
It can — these medications manage appetite while you take them. ARTNER Cheongdam plans them alongside eating and activity changes so the result holds after stopping.
