I can't speak about that brand, but if you aren't happy with the results, many users on this board recommend AllDayChemist. I've used their Tadalafil and had great results. Hopefully, you find success with that one though!
When I inquired for a price on their website, I was contacted soon after by Fiona. I believe their sales team uses several email addresses. They're all variations of the same address. One has a '1', another has a '2' and so on.
