I think if you are from Andorra then it makes sense to buy from them, otherwise given the extra compounds on Mwamba's formula to ensure stability and other growth factors I think it makes more sense to buy from Fue clinic plus they ship from Spain so no tax. Both Parati and Fue Clinic have these compounds on their bottle (mainly RH40, IGF-1 and Phenoxyethanol) so they are an option as well and ship from Italy so no tax either.
