I have lived in Mexico for 9 years. After catching an article about rapamycin I found that I could get it here, without a prescription. Farmalisto in Mexico City to be exact but they do not ship to USA. The cost was 8000 pesos for 60/1mg. tabs. free shipping here. 

I was in bad shape when started last Sept. No energy, I am 69 yrs. Old with borderline diabetes and hypertension. Three months later I joined a Zumba exercise group. I stopped taking it for one week after I got a mouth sore, treated with antibiotics. Felt tired, started rapamune by Pfizer again. Back doing Zumba.
