I've recently tried getting my meds from "genericmedsaustralia.com". Very happy with them.

The thing I don't like about these combo drugs is the dosages they come in. They always come in full doses of each drug per pill, eg 100 mg Sildenafil + 60 mg dapoxetine, and you're stuck with that ratio of doses. You can't do 100mg Sildenafil and only 30 mg dapoxetine. I very much prefer separate pills for each drug because of this.
