Clinical perspective, offered as context rather than as advice.
Mendelian randomization evidence supporting GLP-1 pathway modulation for cardiovascular risk: genetic variants in the GLP1R gene region associated with lower BMI also show associations with reduced cardiovascular risk, confirming a causal pathway[1].
This "natural experiment" (people born with genetically higher GLP-1 signaling being leaner and healthier) provides orthogonal evidence supporting the pharmacological approach. When genetic epidemiology, clinical trials, and mechanistic studies all converge, confidence in the therapeutic approach is high.

Adding a me-too, because a thread of one person's experience is not much use.

Cardiac biomarkers and cardiovascular risk: my cardiologist ordered advanced cardiac labs given my family history. Results were encouraging:
- NT-proBNP: 52 pg/mL (normal, cardiac function preserved)
- Lp(a): 62 nmol/L (genetic, unchanged — expected)
- ApoB: dropped from 137 to 92 mg/dL (excellent response)
- Coronary calcium score: 0 (unchanged from baseline — reassuring)
The ApoB reduction is particularly meaningful — it's considered the best single predictor of cardiovascular risk. GLP-1 therapy seems to improve this consistently.

For anyone assembling their own picture: Tmax is one to three days, terminal half-life about 165 to 170 hours, steady state at four to five weeks, and subcutaneous bioavailability near 89%. Those four numbers explain most of the questions people ask about timing.
One thing that is still open after TrialTracker_MD’s answer:
How much of the between-person variation is pharmacokinetic and how much is just adherence measured badly?
