Guys,

Why is (has the potential to be) Quadmix 'better' than Trimix? In what situations would someone be advised to try Quadmix?

I don't think there is any advantage unless tri-mix is no longer working for you satisfactorily at higher doses and strengths. This is a link to a PDF from Wedgewood Pharmacy that has the best explanation of the various ingredients that I've found. I have no experience with the pharmacy:
