Retatrutide in the Philippines

Retatrutide is an investigational single peptide with agonist activity at three receptors: GLP-1, GIP and glucagon. Semaglutide acts at GLP-1 alone and tirzepatide at GLP-1 and GIP; the glucagon receptor is what retatrutide adds, and in trial populations it is studied for raised energy expenditure alongside the appetite and glycaemic signalling the other two receptors carry. It is in Phase 3 and approved nowhere. TRIUMPH-1, a phase 3 trial in adults with obesity, or overweight with at least one weight-related condition, without diabetes (Lilly investor release, 2026), reported 28.3% mean weight reduction at 80 weeks on the 12mg arm, rising to 30.3% at 104 weeks in the extension cohort. The trial evidence, with the adverse events beside it, is set out below.

Primara Labs stocks retatrutide as a 20mg lyophilized vial, held in cold storage inside Metro Manila. Because inventory is already in the country there is no international shipping leg, no customs exposure and no multi-week wait. Verified orders placed before noon dispatch the same day across Metro Manila, with courier delivery reaches Luzon in 1 to 2 business days, the Visayas in 2 to 3 and Mindanao in 3 to 5.

Each 20mg vial arrives sealed, as a dry powder. Put it in the fridge at 2 to 8°C, away from light, as soon as it lands. To order, tap the WhatsApp button on this page: the chat opens with the vial and pack size already typed, and the reply confirms stock, the peso total and a delivery slot. Orders confirmed before 12 noon get same-day Metro Manila delivery. For the trial history in one place, read the Retatrutide guide on philippinespeptides.com.

Do you give dosing guidance?

No. Retatrutide is supplied for laboratory research only. Primara Labs does not advise on human dosing, titration or administration, on this page or in chat. The reconstitution reference on this page covers concentration only.

Can clinics or resellers buy retatrutide in volume?

Yes. Terms are set per account over WhatsApp rather than published. The wholesale page explains the three programmes.
