Tirzepatide vs. Semaglutide: The Weight Loss Showdown
While both medications are GLP-1 receptor agonists, tirzepatide has a critical advantage: it's a dual agonist that also activates GIP (glucose-dependent insulinotropic polypeptide) receptors. This dual mechanism translates to significantly better weight loss outcomes.
Head-to-Head Clinical Results:
The SURMOUNT-1 trial demonstrated tirzepatide's superiority: at the highest dose, participants lost an average of 22.5% body weight compared to 14.9% with semaglutide in comparable studies. That's 50% more weight loss—a game-changing difference.
Our Verdict: For maximum weight loss, tirzepatide is the clear winner. Access it through CoreAge Rx, which offers both brand-name and affordable compounded tirzepatide options with comprehensive medical support.
GLP-1 Side Effects: What to Expect
All GLP-1 medications share similar side effect profiles since they work through related mechanisms. Understanding what to expect helps you prepare and manage any symptoms effectively.
Most Common (20-40% of patients):
- • Nausea (usually temporary, peaks in first 4-8 weeks)
- • Diarrhea or constipation
- • Decreased appetite (this is therapeutic, not a side effect)
- • Abdominal discomfort or bloating
Less Common (5-15% of patients):
- • Headache or fatigue
- • Dizziness
- • Acid reflux or heartburn
- • Injection site reactions
Rare but Serious (<2% of patients):
- • Pancreatitis (severe abdominal pain)
- • Gallbladder problems
- • Severe allergic reactions
- • Kidney problems (in patients with pre-existing conditions)
Managing Side Effects:
- Start with lower doses and titrate gradually—this significantly reduces nausea
- Eat smaller, more frequent meals instead of large portions
- Avoid high-fat, greasy, or spicy foods that worsen GI symptoms
- Stay well-hydrated, especially if experiencing diarrhea
- Work with your physician on dose timing and adjustments
Providers like CoreAge Rx offer comprehensive side effect management support, helping you navigate any challenges and adjust your treatment plan as needed for optimal results.
GLP-1 Cost Comparison: Finding Affordable Options
Cost is a major factor when choosing a GLP-1 medication. Here's what you can expect to pay for each option, along with strategies to reduce costs.
Cost-Saving Strategies:
- Choose compounded versions: Save 60-80% while getting the same active ingredient
- Check insurance coverage: Some plans cover brand-name GLP-1s for weight loss or diabetes
- Use telehealth providers: Lower consultation fees and competitive medication pricing
- Consider manufacturer coupons: Brand-name medications sometimes offer savings cards (eligibility restrictions apply)
CoreAge Rx offers competitive pricing on compounded tirzepatide with transparent costs and no hidden fees—giving you access to the most effective GLP-1 at an affordable price point.
