The short version
- Tizaro is tirzepatide, the same molecule as Mounjaro, made by Ziska Pharmaceuticals in Bangladesh.
- It costs roughly ₦120,000 to ₦375,000 less per four weeks, depending on the dose.
- It comes as four single-use syringes rather than one pen holding four doses.
- Its maker has published no weight-loss trials of its own, and no UK, US or EU regulator has assessed it.
Tizaro is the reason a lot of Nigerians who priced tirzepatide and walked away are back asking questions. It is the same active ingredient as Mounjaro at a materially lower price. That is a real option, and it carries real trade-offs, so here is the honest version of both.
What Tizaro actually is
Tizaro is a once-weekly tirzepatide injection made by Ziska Pharmaceuticals Ltd in Bangladesh, where it is registered for type 2 diabetes. Tirzepatide is the same active ingredient that is in Mounjaro, but Tizaro is not an Eli Lilly product and is not Mounjaro under another name.
The difference you notice first is the device. Mounjaro arrives as one pen holding four weekly doses. Tizaro arrives as four single-use pre-filled syringes, one per week. The needle cover contains latex, so it is not suitable if you have a latex allergy. Tell us before you order if you do.
Why it costs so much less
Bangladesh has been able to manufacture medicines that are still under patent elsewhere, under a World Trade Organization exemption granted to least-developed countries. That is why Bangladeshi firms can make tirzepatide while the molecule is still protected in the UK, the US and Nigeria.
Bangladesh is now graduating from least-developed country status, and how long that exemption continues afterwards is being argued over. Nobody should assume this price gap is permanent.
What it costs here, against Mounjaro
| Dose | Tizaro, 4 weeks | Mounjaro, 4 weeks | You keep |
|---|---|---|---|
| 2.5 mg | ₦360,000 | ₦480,000 | ₦120,000 |
| 5 mg | ₦390,000 | ₦590,000 | ₦200,000 |
| 7.5 mg | ₦400,000 | ₦710,000 | ₦310,000 |
| 10 mg | ₦470,000 | ₦720,000 | ₦250,000 |
| 12.5 mg | ₦475,000 | ₦850,000 | ₦375,000 |
| 15 mg | ₦550,000 | ₦880,000 | ₦330,000 |
Tizaro prices are current as of 6 October 2026 and Mounjaro prices as of 23 September 2026. Both move with the exchange rate, so confirm before you order.
Where the gap really bites. At 12.5 mg the difference is ₦375,000 every four weeks. Across six months on a maintenance dose, that is the difference between finishing the course and stopping halfway, which is the outcome that wastes the most money of all.
What is the same
- The active ingredient, tirzepatide, at the same labelled strengths.
- The weekly schedule and the same dose ladder, starting at 2.5 mg for four weeks before a treatment dose.
- Storage. Both belong in the fridge at 2–8°C, and both are ruined by heat and by freezing.
- The cautions. A personal or family history of medullary thyroid cancer or MEN 2 rules out tirzepatide whoever makes it, and the oral contraceptive interaction applies the same way.
What you are trading away
- The trial evidence belongs to the original. The weight-loss figures everyone quotes come from Eli Lilly's trials of its own product. Ziska has published no weight-loss trials of Tizaro, and there is no published head-to-head comparison.
- No Western regulator has assessed it. Its registration is for the Bangladeshi market. The UK, US and EU regulators have not reviewed it.
- NAFDAC registration is absent either way. No tirzepatide product, Mounjaro included, appears on NAFDAC's register in Nigeria.
- The device is less forgiving. Four separate syringes mean four chances to mishandle a dose, where a pen does more of the work for you.
Who each one suits
If the monthly figure decides whether you treat at all, Tizaro turns an impossible number into a possible one. A dose you can sustain beats a better-documented one you abandon after two months.
If you want the manufacturer whose trials produced the numbers you have read, and you can carry the cost for as long as you intend to treat, Mounjaro is what that buys.
Checks that matter either way
- Get the batch number and expiry before you pay, then match them against what arrives.
- Check the box is still cold when the rider hands it over.
- Refrigerate immediately, middle shelf, never the door and never the freezer.
- Read the leaflet in the box before your first injection, because syringe technique differs from pen technique.
- Take dose changes to your doctor, as you would with any tirzepatide.
Our guide to checking a pen before you inject applies to syringes too.
