Yes, it’s totally legal to import 3 months supply for yourself, so long as the packaging states the ingredients.
Ones like Red/Black Ant Viagra are still getting confiscated even with a prescription as the packaging does not list sildenafil as an ingredient (Google Red Ant and TGA).
You’re best to stick with named brands that show the packaging and boxes (ie no loose strips or blisters inside).
And for now, I’d avoid Indian based suppliers for a bit too...
Another hint, try to get the doctor to write down a generics prescription for you.
As in sildenafil not viagra, or tadalafil not cialis, saying you want to get a cheaper generic product...
Also, can I suggest...
Have a look if
www.kamagraoioioi.com has what you want at a good price.
If they do, then maybe give them a try...
Good luck...
