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.]
Sourcing note: most readers of this site buy retatrutide from Primara Labs, our partner and supplier. Stock sits inside the Philippines, vials are batch-numbered, and Metro Manila orders verified before noon go out the same day. Retatrutide price Philippines
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 (Ozempic / Wegovy), Tirzepatide (Mounjaro / Zepbound), and Retatrutide, a triple agonist still in Phase 3.
| Peptide | Hospital / pharmacy | Research-grade |
|---|---|---|
| Semaglutide (Ozempic) | Yes, major hospitals | Widely available |
| Tirzepatide (Mounjaro) | Limited, call ahead | Widely available |
| Retatrutide | Not available anywhere | Research-grade sellers only |
| Factor | Semaglutide | Tirzepatide | Retatrutide |
|---|---|---|---|
| Receptors | 1 (GLP-1) | 2 (GLP-1+GIP) | 3 (GLP-1+GIP+Glu) |
| Avg weight loss | 15% | 22.5% | 24 – 29% |
| FDA approved | Yes (2017/2021) | Yes (2022/2023) | Phase 3 |
| Dosing | Weekly | Weekly | Weekly |
| PH monthly cost | USD 90 – 200 | USD 130 – 400 | ~USD 250 |
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.
| 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. |
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 for the current verified list.
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.
