Semaglutide vs. Tirzepatide: Which Weight Loss Treatment Is Right for You?

Two Proven Treatments, One Important Choice

At Curve, we offer two prescription weight loss medications: compounded semaglutide ($99/month) and compounded tirzepatide ($125/month). Both are clinically proven, physician-prescribed, and delivered to your door — but they work differently and may suit different patients better.

Here's what you need to know to have an informed conversation with your Curve provider.

How They're Similar

Both semaglutide and tirzepatide are once-weekly injectable medications that work by mimicking hormones your body naturally produces to regulate appetite and blood sugar. Both have been studied in large clinical trials and shown to produce meaningful, sustained weight loss when combined with lifestyle changes. And both are available at Curve as compounded formulations — the same active ingredients at a fraction of the brand-name cost.

How They're Different

The key difference is mechanism. Semaglutide activates one receptor (GLP-1), while tirzepatide activates two (GLP-1 and GIP). This dual-action approach gives tirzepatide a more powerful metabolic effect:

• Semaglutide — average weight loss of ~15% body weight over 68 weeks (STEP trials)
• Tirzepatide — average weight loss of ~20–22% body weight over 72 weeks (SURMOUNT trials)

Put simply: tirzepatide tends to produce greater weight loss for most patients. However, semaglutide is well-established, has a longer track record, and is effective for many people — especially those newer to GLP-1 therapy.

Which One Might Be Right for You?

Your Curve provider will make the final recommendation based on your health history, goals, and any prior medication use. That said, here are some general patterns:

• Consider semaglutide if you're new to GLP-1 medications, want to start with a well-established option, or are prioritizing the lower monthly cost.
• Consider tirzepatide if you've tried semaglutide before with limited results, have a higher weight loss goal, or want the most clinically advanced option available.

Both medications are dosed gradually — starting low and increasing over weeks — to minimize side effects and maximize results.

What's Included with Either Treatment

Whether you choose semaglutide or tirzepatide, your Curve plan includes the same comprehensive experience: a licensed provider consultation, your prescription, medication prepared in an FDA-registered lab, sterile injection supplies, and free discreet shipping — all with no hidden fees and 24/7 patient portal access.
