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.]

## What GLP-1 peptides actually are

GLP-1 (glucagon-like peptide-1) is a hormone your body naturally produces after eating. It signals satiety, tells your pancreas to release insulin, and slows digestion. GLP-1 agonist peptides mimic this hormone at higher levels, producing strong, durable effects on appetite and weight.

The three main GLP-1 peptides available today are [Semaglutide](https://www.philippinespeptides.com/peptides/semaglutide) (Ozempic / Wegovy), [Tirzepatide](https://www.philippinespeptides.com/peptides/tirzepatide) (Mounjaro / Zepbound), and [Retatrutide](https://www.philippinespeptides.com/peptides/retatrutide), a triple agonist still in Phase 3.

## How GLP-1s actually work

**Appetite suppression.** GLP-1 acts on receptors in the brain that control hunger. Users consistently report dramatically reduced hunger and disappearance of constant food noise.

**Slower gastric emptying.** Food stays in your stomach longer, creating extended fullness. Also why eating too fast causes nausea: your stomach can't process it as quickly.

**Improved insulin response.** GLP-1s enhance insulin secretion in response to food, improving blood sugar control. This is why they were originally developed for type 2 diabetes.

**Glucagon activation (retatrutide only).** Retatrutide's third receptor directly increases metabolic rate. Your body burns more calories at rest, including stored fat. This explains the extra ~6% weight loss vs tirzepatide.

## Results timeline

| Timeframe | What happens |
| --- | --- |
| Week 1 – 2 | Appetite begins decreasing. Side effects (nausea) peak. No significant weight change yet. |
| Week 3 – 4 | Nausea subsides. First noticeable weight loss (1 – 3kg). Eating less feels natural. |
| Month 2 – 3 | Steady weight loss (1 – 2kg/week). Energy improves. Clothes fit differently. |
| Month 4 – 6 | Approaching goal weight. Rate of loss slows. Body composition improving. |
| Month 6+ | Maintenance phase. Some users reduce dose. Lifestyle changes solidify. |

## Who should not use GLP-1s

- · Personal or family history of medullary thyroid carcinoma (MTC)

- · Multiple Endocrine Neoplasia syndrome type 2 (MEN2)

- · History of pancreatitis

- · Type 1 diabetes

- · Pregnancy or breastfeeding

- · Severe gastrointestinal disease

- · Under 18 years old

## Sourcing GLP-1s in the Philippines

**Hospital / international clinic.** Brand-name Ozempic and Mounjaro available at Makati Medical Center, Manila Doctors Hospital, and select international pharmacies. Pharmaceutical-grade with doctor supervision; expensive and limited to approved compounds.

**Research-grade sourcing.** Access to retatrutide and the lower-cost tirzepatide / semaglutide route. Batch-numbered, often with physician review. See [/supply](https://www.philippinespeptides.com/supply) for the current verified list.

The decision

## Philippines-specific considerations

**Climate.** Heat degrades peptides quickly. Ensure cold-chain to your door, immediate refrigeration on receipt (2 – 8°C), never leave vials at room temperature.

**Supplies.** Insulin syringes are available at Watsons and Mercury Drug nationwide without prescription.

**Alcohol.** GLP-1s significantly reduce alcohol tolerance. One drink hits like three. Start slow if drinking.

**Local support.** Join r/PeptidesPhilippines for region-specific questions, supplier feedback, and local experiences.
