Week 23: Approaching the Half-Year Mark
Three doses into 15mg, the maximum dose is fully steady-state. With one week to the six-month milestone, this is the moment to gather the data and start reading the half-year picture.
Six months is the largest published checkpoint in real-world obesity pharmacotherapy practice. In SURMOUNT-1, participants in the 15mg arm had reached an average cumulative loss of approximately 20% by trial endpoint, with the curve at week 24 typically landing in the 18 to 20 percent range. Real-world outcomes track somewhat lower on average but follow the same shape.
Week 23 sits between two important reads. The week's number is itself meaningful — it is the cleanest mid-cycle read on 15mg — but the more useful framing is preparation. Pull together the data now so the half-year milestone next week is a structured review rather than a number on a single day.
Appetite Suppression
Stable near-total. The pattern of eating by schedule rather than by hunger is fully established at this point for most 15mg users.
Typical mid-cycle loss at 15mg. The slope is flatter than the earlier months but the line continues for most users.

Day 155 (Injection 23)
Third 15mg Dose
Routine injection at maximum-dose steady state. The week ahead is quiet — no titration, no peak symptoms, no surprises.
Days 157-159
Pre-Milestone Audit
Gather the data: starting weight, current weight, waist, blood pressure, lab work if available, a side-by-side weekly trend chart. The full picture is most readable when prepared in advance.
Day 161
End-of-Week Read
The last weigh-in before the six-month milestone. The number itself is one data point; the trend that brought you here is the story.
Navigating Symptoms
At the half-year mark, side effect questions usually shift from 'is this normal' to 'is this manageable long-term'. Most users find the answer at 15mg is yes; for some, a step down to 12.5mg for maintenance becomes worth discussing.
Body composition data deserves attention this week if you can get it. A DEXA scan or even a careful tape measurement of waist, hips, thigh, and arm gives a quantitative picture of where the loss has come from. Lean mass preservation across six months is the marker of a sustainable program.
What Users Report
“Week 23, the calmest one yet. The whole thing has become routine. I think about food less than I think about the weather. Scale moved a pound this week, no effort.”

“Approaching six months and looking at what is next. Considering stepping down to 12.5mg once I hit goal. The conversation about maintenance is starting now.”
