Has anyone used IndiaMart or other places to buy cialis/tadalafil etc.?

I live in Tokyo and want to get some low-dose cialis to take daily as lately I've had issues staying hard or finishing sometimes. I've already gone to a clinic and had my testosterone checked (was 615 at almost 42YO, so that's good) and it wasn't an issue. The doctor asked if I wanted a prescription for cialis/tadalafil which I took, but the pills are expensive. Even the generic 20mg of cialis for 2 pills was over 3000 yen, and you can't use NHI for it, so I would like to find a cheaper option.

I already go to the gym and am in-shape and have never been out of shape (my BMI is around 21.8 after gaining 5kg, so that isn't an issue as well), but maybe I lack cardio/have low blood pressure, so I've been adding cardio to the end of my workouts as well. I would still like to have that little boost in erection quality instead of losing it part-way and not being able to finish though, so if anyone has any recommendations for getting cheap cialis/tadalafil, let me know. I think I read that cialis will become an OTC medicine in Japan this year sometime, so hopefully that will happen and there won't be a need to go through such hoops to purchase it.
