TL;DR: We've launched the SiPhox Health GLP Monitoring Panel: at-home blood testing and body composition tracking built specifically for people on GLP-based therapy (Ozempic, Zepbound, Retatrutide, etc.).

✅ 40+ lab markers covering metabolism, lipids, liver, kidney, thyroid, hormones, and nutrition

✅ Painless upper arm patch at-home collection — no lab visits, no appointments, no finger pricks

✅ In-app body-composition scanner to track fat loss vs. muscle preservation

✅ GLP Tolerance Score — built from your labs, body comp, and symptom check-ins

✅ Symptom check-ins for fatigue, brain fog, hair shedding, GI issues, and muscle loss

✅ Wearable integration — Apple Health, Oura, Whoop, Dexcom, Libre, etc.

✅ Upload third-party labs (Quest, Labcorp, etc.) for a complete picture in one dashboard

✅ $199 — HSA/FSA eligible

🔨 Why We Built This

We're Getting Into the GLP Game — But Not With a Me-Too Product

30 million Americans are currently on GLP drugs. That number is going up. Access is getting easier, prices are falling, and the longevity research on low-dose GLP therapy is compelling enough that it's not hard to imagine most adults cycling on and off these medications eventually, not just for weight loss, but for metabolic health and lifespan.

There are plenty of places to buy Ozempic, but the monitoring and optimization infrastructure is not there yet. The biology of GLP therapy is more complicated than the weight loss headline suggests:

🚫 Muscle loss is hidden by the scale. Fast weight loss often means lean mass loss, not just fat. Standard weight tracking can't tell the difference.

🚫 Side effects are downstream signals. Fatigue, brain fog, hair shedding, and constipation aren't random — they're often markers of caloric under-fueling, nutrient depletion, or dehydration pressure that bloodwork would catch early.

🚫 Prescribers don't monitor the full picture. Most GLP patients get minimal follow-up labs, if any. HbA1c, ApoB, ferritin, B12, testosterone, thyroid — none of these are standard-of-care during treatment.

🚫 Weight alone is a bad success metric. Losing 24 lbs while losing 6 lbs of muscle and depleting your ferritin is not the same as losing 24 lbs of fat.

The Solution: A Monitoring Loop Built for GLP Therapy

We've served 50,000+ users with at-home blood testing. GLP users are a distinct population with distinct needs, so we built a product specifically for them. The SiPhox GLP Monitoring Panel connects labs, body composition, and symptom tracking into one continuous loop so you can see what the drug is actually doing to your biology and course-correct before small problems become bigger ones.

💡 What You Get

✅ 40+ Lab Markers — GLP-Specific Panel

Not a generic wellness panel. Built around the markers that matter when appetite, weight, hydration, and body composition are actively changing:

• Metabolism: HbA1c, eAG, C-Peptide
• Lipids & heart: ApoB, LDL, HDL, Triglycerides, hsCRP
• Liver: ALT, AST, ALP, bilirubin, albumin
• Kidney & hydration: BUN, creatinine, eGFR, BUN:Cr ratio
• Thyroid: TSH, Free T4
• Hormones: Testosterone (total + free + %), SHBG, cortisol
• Nutrition: Vitamin D, B12, folate, ferritin, iron studies (Iron, UIBC, TIBC, Iron Saturation), total protein

✅ Painless At-Home Collection

Collected via our Easydraw arm patch, no venous draw, no finger prick, no lab visit. Mail it back, and the results appear in your dashboard.

✅ Body-Composition Scanning

In-app scanner tracks fat loss vs. lean mass preservation between tests.

✅ GLP Tolerance Score

A composite score built from labs, body comp, and symptom check-ins. Tracks how well your body is handling therapy at each stage: baseline → titration → maintenance.

✅ Symptom & Side-Effect Tracking

Track fatigue, brain fog, hair shedding, GI issues, and muscle soreness between tests. Connects subjective experience to objective lab data.

✅ Detailed Analysis & Personalized Insights

Interpret what's moving in the right direction, what deserves a conversation with your prescriber, and what to adjust in diet, training, or supplementation built around your specific results.

📈 Why Now?

GLP drugs are the fastest-growing drug class in history. Next-gen peptides like retatrutide, orforglipron, cagrilintide are coming. The longevity use case is expanding the addressable population well beyond obesity treatment. And monitoring has not kept pace with any of it.

Most patients are flying blind. Prescribers don't have the bandwidth for individualized follow-up. Labs are ordered inconsistently, if at all. No one is connecting weight, body composition, symptoms, and biomarkers in a single continuous view.
