Retatrutide in the Philippines
Retatrutide is an investigational triple agonist that binds GLP-1, GIP and glucagon receptors simultaneously. In published Phase 2 data (Jastreboff et al., NEJM 2023) it produced a mean 24.2% body weight reduction over 48 weeks at the highest studied dose. Phase 3 TRIUMPH-1 has since reported 28.3% over 80 weeks, the largest effect recorded for any incretin-class compound to date. That result is why retatrutide is the most requested research peptide in the Philippines right now.
Primara Labs stocks retatrutide as a 15mg 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 nationwide courier delivery running 1 to 3 days.
Every vial ships in insulated cold-chain packaging with the batch number printed on the label, so orders are traceable to their production lot. Pricing is transparent and in pesos: ₱3,325 per vial, or ₱2,990 with the standing 10% off.
Retatrutide remains an investigational compound. It is not FDA approved, and everything sold on this page is supplied strictly for laboratory research use. It is not for human consumption, and Primara Labs does not provide medical advice, dosing guidance for people or clinical support.
Research focus
- Mechanism: single peptide activity at GLP-1, GIP and glucagon receptors, studied for additive effects on energy expenditure alongside appetite signaling.
- Phase 3 TRIUMPH-1: 28.3% mean weight reduction at 80 weeks at 12mg, rising to 30.3% at 104 weeks. Phase 2 (NEJM 2023) reported 24.2% at 48 weeks, dose-dependent across 1mg to 12mg weekly arms.
- Phase 3 TRIUMPH-1 at 28.3% over 80 weeks, plus TRIUMPH-2 in type 2 diabetes and TRIUMPH-3 in cardiovascular disease.
- Glucagon receptor activity is the differentiator under study versus semaglutide (GLP-1 only) and tirzepatide (GLP-1 plus GIP).

Retatrutide questions, answered
How much does retatrutide cost in the Philippines?
Primara Labs supplies retatrutide 15mg vials at ₱3,325, or ₱2,990 with the standing 10% off. Stock is held inside the Philippines, so there are no import fees, customs risk or international shipping costs on top.
Is retatrutide in stock and how fast is delivery?
Retatrutide 15mg is in stock. Verified orders placed before noon dispatch the same day across Metro Manila. Provincial orders ship by insulated courier and typically arrive in 1 to 3 days.
Is retatrutide legal in the Philippines?
Retatrutide is an investigational compound, not a controlled substance in the Philippines. It is supplied strictly as a research chemical for laboratory use and is not FDA approved for human use.
How is retatrutide reconstituted for research use?
The lyophilized powder is reconstituted with bacteriostatic water. Adding 2.0 ml to a 15mg vial yields a 7.5 mg/ml reference concentration. Reconstituted material should be refrigerated and used within 28 days.
How does local stock change delivery compared to importing?
Ordering from overseas suppliers means customs screening at NAIA, cold-chain risk over a 1 to 3 week transit and no recourse if a package is held. Primara Labs vials are already inside the Philippines, so Metro Manila orders arrive the same day and provincial orders within days, in insulated packaging the whole way.
How do I order retatrutide from Primara Labs?
Ordering runs through WhatsApp. Tap the order button on this page and the chat opens with your vial pre-filled. Confirm quantity and delivery details in the conversation and payment instructions follow there.
