Your body has a spec sheet — the same way a new car has a window sticker. Stop guessing the fuel.

Coach insight
You wouldn’t put diesel in a Ferrari.
Bloodwork is the check-engine light — it tells you something is wrong right now. DNA is the factory spec sheet: how this engine wants fuel, oil, and RPM before anything overheats.
Check engine vs window sticker
Blood test
- Reactive — after damage starts
- Changes daily
- “Take this pill to cool it down”
DNA kit
- Proactive — factory wiring
- Source code is stable
- “Use the right coolant so it never overheats”

Window sticker
When you buy a new car you read the Monroney label on the glass — VIN, options, fuel economy, MSRP. GxSlim is that sticker for your biology. Tap a spec on the sticker.

Semi-fasted cardio, then a choline breakfast.

FAQ
Is this a medical diagnosis?
No. GxSlim is a wellness genetics product for educational lifestyle insights. It does not diagnose disease or prescribe treatment.
How long until results?
Typically around 3 weeks after the lab receives your sample (shipping and lab volume vary).
Do I need a doctor visit?
No appointment to order. Collection is at home. If you have health conditions, consult a clinician before acting on lifestyle changes.
$200 vs $300?
$200 is the Full Biological Schematic. +$100 adds anonymous processing so the laboratory workflow can use a private processing ID.
Who is Lab Testing Solutions?
LTS has provided lab testing since 2011 (employer, legal, and consumer pathways). GxSlim is the consumer DNA wellness kit. labtestingsolutions.com · 1-866-777-8667
