I just got 30 pills of 25mg empagiflozin for $60 from a pharmacy in Roatan, Honduras (Farmacias del Ahorro)
metformin is dirt cheap ($8.50 for a pack of 850 mg pills)
It did not have acarbose, rapamycin, canagliflozin, or selegiline. Diabetes is common in Latin America so the pharmacies there should have anti-diabetic medication.
Also it has Fibra con lecitina (corn fiber) which is an interesting product not found in the US…
