Video guide: GLP-1 Medicines in the Philippines, Explained (2:12)

New to GLP-1s in the Philippines? Here is what they are, what is registered, and the three ways to get them. GLP-1 is a hormone released after you eat. These medicines mimic it: more fullness, more insulin, slower digestion. Semaglutide acts on one receptor, tirzepatide on two, and retatrutide on three. Retatrutide is still investigational. In phase 3 trials, top-arm mean weight loss was 14.9% in STEP 1, 20.9% in SURMOUNT-1, and 28.3% in TRIUMPH-1. Ozempic, Wegovy, Mounjaro and Rybelsus are registered with FDA Philippines as prescription medicines. Prescribing belongs with a licensed Philippine physician. Route one, a pharmacy. At Watsons, an Ozempic 1 mg pen is ₱9,280. Mounjaro pens reach ₱29,900. Route two, telehealth, after a doctor's review. GoRocky lists from ₱3,990 a month. &you, ₱599 a month after a free first month, plus medication. Route three, research vials. Not the same product: a pen is a registered prescription medicine. A research vial is not approved for human use and is sold for research only. Our partner and supplier, Primara Labs, lists 15 mg vials: semaglutide, ₱1,990. Tirzepatide, ₱1,890. Retatrutide, [₱3,390 for the 20 mg vial]. Per mg, the Ozempic pen is about ₱2,320. The semaglutide research vial works out at ₱133 per mg, or ₱81 in a 10 pack. Not the same product. Every order includes bacteriostatic water, syringes and alcohol pads. Same day in Metro Manila before noon, J&T nationwide, and a 60-day money-back guarantee. Read the full GLP-1 guide on Philippines Peptides, then see the research vials at Primara Labs and order on WhatsApp. [Figures in square brackets corrected on 3 November 2026 from Primara's current catalogue: the narration gives the price of the 15 mg retatrutide vial, retired on 12 October 2026.]

## How the three trial programmes compare

**Retatrutide** is a triple agonist (GLP-1, GIP and glucagon receptors) developed by Eli Lilly. It is investigational and approved nowhere. In TRIUMPH-1, an 80-week phase 3 trial of 2,339 adults with obesity, or overweight with at least one weight-related condition, without diabetes, body weight fell by 19%, 25.9% and 28.3% on the 4 mg, 9 mg and 12 mg arms, against 2.2% on placebo. [Source](https://investor.lilly.com/news-releases/news-release-details/lillys-triple-agonist-retatrutide-delivered-powerful-weight-loss) The [retatrutide guide](https://www.philippinespeptides.com/peptides/retatrutide) lists its side effects from the same trials and its regulatory status, and the [retatrutide Philippines 2026 guide](https://www.philippinespeptides.com/guides/retatrutide-philippines-2026) covers the Philippine picture.

**Semaglutide** is a GLP-1 receptor agonist developed by Novo Nordisk, the active ingredient in Ozempic (approved by the US FDA for type 2 diabetes in 2017) and Wegovy (approved for weight management in 2021). In STEP 1, a 68-week phase 3 trial of 1,961 adults with BMI of 30 or greater (27 or greater with at least one weight-related coexisting condition), without diabetes, body weight fell by 14.9% on the 2.4 mg arm, against 2.4% on placebo.

**Tirzepatide** is a dual agonist (GLP-1 and GIP receptors) developed by Eli Lilly, the active ingredient in Mounjaro and Zepbound. In SURMOUNT-1, a 72-week phase 3 trial of 2,539 adults with BMI of 30 or more, or 27 or more with at least one weight-related complication, excluding diabetes, body weight fell by 15%, 19.5% and 20.9% on the 5 mg, 10 mg and 15 mg arms, against 3.1% on placebo. [Source](https://doi.org/10.1056/NEJMoa2206038) Read the [tirzepatide Philippines 2026 guide](https://www.philippinespeptides.com/guides/tirzepatide-philippines-2026).

These trials enrolled different populations over different lengths of time, so the figures are not a head-to-head comparison. Each compound page places the adverse events from the same trials next to the outcomes.

## The four options explained

Triple-agonist

### Retatrutide

[Retatrutide](https://www.philippinespeptides.com/peptides/retatrutide) is a triple-agonist peptide that activates GLP-1, GIP, and glucagon receptors. In TRIUMPH-1, a phase 3 trial, the 12 mg arm lost 28.3% of body weight on average at 80 weeks. In the Philippines, retatrutide isn't available at any pharmacy or hospital. The [retatrutide Philippines 2026 guide](https://www.philippinespeptides.com/guides/retatrutide-philippines-2026) covers COA red flags and legal status.

Dual-agonist

### Tirzepatide

[Tirzepatide](https://www.philippinespeptides.com/peptides/tirzepatide) is a dual-agonist peptide that activates both GLP-1 and GIP receptors. In SURMOUNT-1, a phase 3 trial, the 15 mg arm lost 20.9% of body weight on average at 72 weeks. Mounjaro registration and dated pharmacy prices are on the [Mounjaro page](https://www.philippinespeptides.com/guides/mounjaro-philippines). See the [tirzepatide Philippines 2026 guide](https://www.philippinespeptides.com/guides/tirzepatide-philippines-2026) or the focused [tirzepatide weight loss page](https://www.philippinespeptides.com/weightloss/tirzepatide).

GLP-1 single-agonist

### Semaglutide

[Semaglutide](https://www.philippinespeptides.com/peptides/semaglutide) is a GLP-1 receptor agonist, FDA-approved as Ozempic (diabetes) and Wegovy (obesity). In STEP 1, a phase 3 trial, the 2.4 mg arm lost 14.9% of body weight on average at 68 weeks. See the [semaglutide Philippines 2026 guide](https://www.philippinespeptides.com/peptides/semaglutide) or the focused [semaglutide weight loss page](https://www.philippinespeptides.com/weightloss/semaglutide).

Amylin analogue

### Cagrilintide

[Cagrilintide](https://www.philippinespeptides.com/peptides/cagrilintide) is an amylin analogue that works through a different mechanism than GLP-1 agonists. Amylin slows gastric emptying and signals satiety via different brain pathways than GLP-1. Novo Nordisk is testing cagrilintide combined with semaglutide in phase 3. The trials dataset this site draws on holds no cagrilintide result, so this page states no figure for it.

## Branded medicines and research-grade peptides

Ozempic, Wegovy and Mounjaro are prescription medicines. Registration numbers and dated pharmacy prices are on the [GLP-1 price tracker](https://www.philippinespeptides.com/prices).

Prescription only; prescribing belongs with a licensed Philippine physician. Trials and side effects: the [tirzepatide guide](https://www.philippinespeptides.com/peptides/tirzepatide). The law: [regulation hub](https://www.philippinespeptides.com/legal).

Research-grade peptides are a separate category: research materials, not pharmacy products, and not a substitute for a prescribed medicine. The [supplier checklist](https://www.philippinespeptides.com/supply) sets out what to ask a seller before paying, and the [buying peptides in the Philippines guide](https://www.philippinespeptides.com/guides/buy-peptides-philippines) covers the rules on personal import.

A proper COA comes from a third-party lab independent of the seller, shows HPLC purity testing with a clear chromatogram, lists actual peptide content in milligrams, and includes the specific batch number that matches your vial. The [COA verification guide](https://www.philippinespeptides.com/coa) explains how to read HPLC chromatograms and spot fake certificates.

## Before buying anything

Work through the [supplier checklist](https://www.philippinespeptides.com/supply) and the [COA guide](https://www.philippinespeptides.com/coa), and read the compound page for what its trials found and the side effects they reported. Anything you intend to use belongs in a conversation with a licensed Philippine physician first.
