Clinical Results

Tirzepatide delivers more. Clinically proven.

In head-to-head trials, tirzepatide outperformed semaglutide (Ozempic/Wegovy) on every key metric.

Receptors activated
Tirzepatide targets GLP-1 and GIP receptors. Semaglutide targets GLP-1 only — one mechanism, weaker results.

In clinical trials, 9 out of 10 tirzepatide patients achieved at least 5% body weight reduction.
Why Tirzepatide

Why we prescribe tirzepatide — not semaglutide.

Most online weight loss platforms prescribe compounded semaglutide (the generic version of Ozempic and Wegovy). We don't — because the FDA ended semaglutide's shortage status, creating legal uncertainty for compounders.

Tirzepatide (the active ingredient in Zepbound®) is still on the FDA shortage list — making it fully legal to compound. And clinically, it's the better drug: two receptor targets, greater appetite suppression, and superior weight loss outcomes.

FAQ

Common questions about tirzepatide.

Is tirzepatide safe? ▾
Tirzepatide (brand name Zepbound®) is FDA-approved for chronic weight management in adults with obesity or overweight with a weight-related condition. Our compounded version is produced in FDA-regulated, state-licensed 503A pharmacies under strict quality controls. Your physician reviews your full medical history before prescribing.
How is tirzepatide different from Ozempic or Wegovy? ▾
Ozempic and Wegovy contain semaglutide, which activates only the GLP-1 receptor. Tirzepatide activates both GLP-1 and GIP receptors — producing greater appetite suppression, better insulin sensitivity, and significantly more weight loss. Clinical trials showed 22.5% average body weight reduction vs 14.9% for semaglutide.
Do I need insurance? ▾
No. ZENKAI Weight is a cash-pay program. Your $199/month covers the physician consultation, prescription management, AI coaching, and free shipping — no insurance required.
What if I don't qualify? ▾
If your physician determines tirzepatide is not appropriate for your health profile, you will not be charged. We only bill you after a prescription is issued. Your intake assessment is completely free.
How do I administer the medication? ▾
Tirzepatide is a once-weekly subcutaneous injection — using a small pen-needle into the fatty layer of your abdomen, thigh, or upper arm. It's much simpler than it sounds. Your physician provides full injection guidance at consultation, and our AI coach answers follow-up questions 24/7.
Can I cancel anytime? ▾
Yes. All ZENKAI programs are month-to-month with no long-term contracts or cancellation fees. Cancel anytime through your patient portal or by messaging our support team.
Is compounded tirzepatide legal? ▾
Yes. Tirzepatide remains on the FDA's drug shortage list, which legally permits state-licensed compound pharmacies to produce it under FDA regulation. This is distinct from compounded semaglutide, which is under enforcement action after being removed from the shortage list.
When will I start seeing results? ▾
Most patients report reduced appetite within the first week. Meaningful weight loss (5%+ of body weight) typically begins within 4–8 weeks, with results accelerating as your physician titrates your dose upward over 12–20 weeks. Full clinical results develop over 6–12 months.
