What should I check if I am not losing weight on a GLP-1?

Short answer
Before concluding anything, look at the trend over time rather than a single week, check whether the product was handled and stored as its labeling states, whether the prescribed regimen has been followed, and what changed in your intake, activity, other medications or medical factors. Treatment changes are decided by whoever provides your clinical follow-up, not a web page or a forum.
In plain English
- Trend: look at several weeks in a row, not one data point.
- Prescribed regimen: whether it has been followed as directed, and for how long.
- Storage and handling per that specific product's labeling; not every product requires refrigeration.
- Context: intake, activity, sleep, alcohol, other medications and medical factors.
What we know
- Plateaus can occur in any weight-loss intervention; there is no universal two-to-three-week rule.
- Storage conditions and the in-use period are set by each product's labeling.
What we don't know yet
- Whether a clinical factor is involved in your specific case — that needs professional assessment.
