SURMOUNT-5 answered the question the field argued about for years. Here is what the data says, and what each compound costs from a Philippine vantage point. Semaglutide vs Tirzepatide: Head-to-Head Trial (Philippines)1:53·[Transcript and chapters](https://www.primaralabs.com/videos/semaglutide-vs-tirzepatide) ## What SURMOUNT-5 settled For years the comparison ran on indirect evidence. Semaglutide's STEP 1 (NEJM 2021) reported 14.9% mean weight reduction at 68 weeks. Tirzepatide's SURMOUNT-1 (NEJM 2022) reported 22.5% at 72 weeks. Bigger number, but different trials, so the debate continued. SURMOUNT-5 ended it by running the two compounds against each other directly, and the result favored tirzepatide. The dual GIP and GLP-1 mechanism outperformed the single GLP-1 mechanism in the same trial, on the same protocol, in the same population. For research purposes that head-to-head matters more than any cross-trial comparison. It is the cleanest published evidence that adding GIP receptor activity to a GLP-1 backbone changes the outcome, and it is the reason the field kept moving toward multi-receptor designs like retatrutide, covered in the [retatrutide comparison](https://www.primaralabs.com/blog/retatrutide-vs-tirzepatide-price). ## The local availability picture In the Philippines semaglutide reaches a buyer two ways. As a prescription pharmaceutical it is Ozempic pens through hospital and retail pharmacies, prescription required, monthly costs that run to five figures in pesos. Sold for research use, it is a lyophilized vial: Primara Labs stocks [semaglutide 15mg](https://www.primaralabs.com/marketplace/semaglutide-15mg) at ₱2,210, or ₱1,990 with 10% off. Tirzepatide exists on both sides. Mounjaro is the pharmacy product, and tirzepatide sold for research use ships as a 15mg lyophilized vial at **₱2,100**, or **₱1,890 with 10% off**. The [tirzepatide product page](https://www.primaralabs.com/marketplace/tirzepatide-15mg) shows live stock; vials are in stock and dispatch same day across Metro Manila on verified orders. ## What this means for a research buyer If the research question is about the best-documented incretin, semaglutide keeps that title on sheer volume of human data, and it is now stocked here as an RUO vial as well as sold as a pharmacy pen. If the question is about the stronger published outcome, SURMOUNT-5 gives that to tirzepatide, and the vial route prices it at a fraction of pen cost. And if the question is about where the field is heading, the answer is already past both: triple-agonist work has moved to [retatrutide](https://www.primaralabs.com/marketplace/retatrutide), which is in stock now at ₱3,390 with 10% off. Whichever way the work points, orders verified before noon dispatch same day across Metro Manila, with courier reaching Luzon in 1 to 2 business days, the Visayas in 2 to 3 and Mindanao in 3 to 5.

SURMOUNT-5, the direct head-to-head trial, favored tirzepatide over semaglutide. Before that, tirzepatide reported 22.5% mean weight reduction at 72 weeks in SURMOUNT-1 (NEJM 2022) against semaglutide's 14.9% at 68 weeks in STEP 1 (NEJM 2021). ### How much is a tirzepatide vial in the Philippines? Tirzepatide 15mg lists at ₱2,100 at Primara Labs, or ₱1,890 with the 10% discount. ### Is semaglutide available as a vial from Primara Labs? Yes. Semaglutide 15mg is stocked at ₱2,210, or ₱1,990 with the standing 10% off, as a lyophilized vial sold for research use only. The Ozempic pen sold through pharmacies is a separate product in a separate market. ### What is the mechanistic difference between the two compounds? Semaglutide activates one receptor, GLP-1. Tirzepatide activates two, GIP and GLP-1. The added GIP activity is the leading explanation in the literature for the difference in trial outcomes.
