Tirzepatide vs Retatrutide in the Philippines
Two receptors or three. Both are 39-amino-acid multi-agonists from the same class, and the glucagon arm is the whole difference. Here is what that changes mechanistically, what each is used to study, and how the local pricing compares.
A comparison of research reference materials
Everything below describes what these compounds do in published in vitro and animal-model research. Both are supplied strictly as analytical reference materials for laboratory research — not as medicines, and not for human or animal use. We do not provide dosing or clinical guidance for either compound.

Comparing price in the Philippines
Retatrutide usually carries the higher price per vial, being newer and less widely supplied. Unlike a tirzepatide-versus-semaglutide comparison, though, these two are stocked at the same 10 mg size and reconstitute to comparable working concentrations — so the headline figures are reasonably comparable units rather than misleading ones. Both are held in Metro Manila, so the listed PHP price plus the shipping shown at checkout is the full amount, with no customs or brokerage charges arriving afterwards.
Frequently asked questions
What is the difference between tirzepatide and retatrutide?
Both are 39-amino-acid multi-receptor agonists, and the difference is the number of receptors engaged. Tirzepatide activates two — GIP and GLP-1. Retatrutide activates those two plus the glucagon receptor. That third arm is the entire distinction, and it is what research credits for retatrutide's standout hepatic lipid-mobilisation and energy-expenditure readouts, on top of the incretin signalling both share.
Why are they studied side by side?
Because they isolate a specific question: what does adding glucagon-receptor engagement do to an already-dual incretin backbone? Running them in parallel in the same assay system is how the literature separates the contribution of the glucagon arm from the GIP and GLP-1 signalling both compounds share. Laboratories profiling the class usually run semaglutide alongside them as the single-receptor baseline.
Which costs more in the Philippines?
Retatrutide typically carries the higher price per vial as the newer and less widely supplied compound. Both are stocked here at 10 mg and reconstitute to comparable working concentrations, so unlike a tirzepatide-versus-semaglutide comparison the per-vial figures are reasonably comparable units. Current PHP pricing for each size is on the product pages, and because both are held in Metro Manila there are no customs or import charges added afterwards.
Can I get both delivered in the Philippines?
Yes. Both are stocked in Noxa Labs Metro Manila cold storage. Orders placed Mon–Fri before 2 PM PHT dispatch the same day within Metro Manila; Greater Luzon runs 3–5 business days and Visayas and Mindanao 5–7. Payment is by GCash, USDT or card, and both ship with a batch COA you can verify by the code on the vial.
