GLP-1s work, and they carry specific, monitorable risks. Rapid weight loss changes gallbladder, kidney, thyroid and nutrient status, and a large share of the weight lost can be lean mass if protein and training aren't right. This panel tracks efficacy and safety together.
The 11 markers — and why each one is here
Liver, kidney, electrolytes — all move with rapid weight loss
Falls with visceral fat loss — a good progress marker
Ordering the panel tells you your numbers. The protocol tells you what to do with them — how much of the weight you lose is muscle and what the trials show actually prevents it, the monitoring nobody mentions, the exit plan for when you stop, and the one popular peptide that works against the drug you're paying for.

No. These are ordered direct-to-consumer through Marek Diagnostics — you order online, walk into a Quest location, and results are emailed to you in about two weeks. No physician visit or insurance required. Not available in NY, NJ or RI.
Baseline before starting, then at 3 months and 6 months. Fast 9–12 hours. Draw at least 48 hours after your injection if you're on a weekly protocol.
Falling HbA1c and fasting insulin = it's working metabolically. Rising lipase with abdominal pain → stop and see a doctor. Falling IGF-1 with rapid loss → increase protein and add resistance training. Watch ferritin and B12 — reduced food intake means reduced nutrient intake.
