Semaglutide vs. Tirzepatide: Which One Is Right for You?

Let’s break it down — so you can make the most informed choice for your body and goals.

If you’re considering starting GLP-1 medications for weight loss, insulin resistance, or PCOS, you’ve probably come across two big names: Semaglutide (Ozempic, Wegovy, or compounded versions) and Tirzepatide (Mounjaro or compounded versions).

Both are incredibly effective, but they’re not identical. The best option depends on your body, your goals, and your budget.

Here’s a science-backed breakdown to help you choose.

⚙️ The Mechanism: How They Work

✅ Semaglutide

  • Mimics the GLP-1 hormone, which slows digestion, reduces appetite, and improves insulin sensitivity.

  • Taken weekly by injection (or compounded for daily microdosing).

  • Originally created for type 2 diabetes, now widely used for weight loss.

✅ Tirzepatide

  • Mimics two hormones: GLP-1 and GIP (glucose-dependent insulinotropic polypeptide).

  • The dual-action increases insulin response even more and may lead to stronger appetite suppression.

  • Also taken weekly or compounded for daily use.

  • Often results in faster weight loss than Semaglutide, but with a higher side effect potential.

💰 Cost Comparison

Medication Avg Monthly Cost With Microdosing Discounted Option
Semaglutide $250–$1,200/mo ~$150–$250/mo Fierce or ShredRX – $50 off
Tirzepatide $500–$1,300/mo ~$250–$350/mo Fierce or ShredRX – $50 off

💡 Note: Compounded versions (legally made by pharmacies) can significantly reduce costs.

🔥 Appetite Suppression & Weight Loss

Category Semaglutide Tirzepatide
Appetite Control Strong Very Strong
Average Weekly Weight Loss ~1–2 lbs/week ~1.5–3 lbs/week
Onset of Fullness Effect 1–3 weeks 1–2 weeks
Risk of Nausea Moderate Higher (especially at first)

Tirzepatide tends to suppress appetite more aggressively, which can be great for some — but too intense for others, especially with a history of disordered eating or sensitivity.

💬 User Experience: What People Are Saying

Semaglutide Users:

  • Feel more “in control” of cravings

  • Experience gentle fullness with fewer side effects

  • Often use it with lifestyle changes like strength training + mindset work

Tirzepatide Users:

  • Report fast results — sometimes too fast

  • Stronger food aversions, occasional nausea

  • Can feel like a “hard stop” on appetite (good or bad, depending on the person)

🧠 What to Consider When Choosing

Ask yourself:

  • Do I want faster results or gentler hunger reduction?

  • Am I okay with stronger side effects in exchange for quicker loss?

  • What’s my budget?

  • Do I want flexibility to microdose and adjust my own dose?

  • Do I have the support to manage rapid weight loss (muscle training, emotional tools)?

📌 My Recommendation:

Start with Semaglutide if:

  • You’re new to GLP-1 meds

  • You want to microdose slowly

  • You’re concerned about side effects

  • You’re pairing the medication with a full lifestyle plan

Consider Tirzepatide if:

  • You’ve tried Semaglutide and want more powerful effects

  • You have a lot of weight to lose quickly and need aggressive support

  • You have medical supervision and a strong self-care routine in place
