If you get a US prescript
ion, there has been a "first month free" offer from Cialis. The doctor gave me a sample that had the coupon which my pharmacy honored, but you can also get one on line at their web site. The quantity varies on the strength.
I'm on 5mg, and they gave me a 30 pill supply. If larger doses, they do smaller quantity.
I've had my prescription changed to the 20mg, since insurance will pay for only 8 per month regardless of strength, and (very carefully) cut them into quarters, more or less.
Even if you go the ADC route, you might have the prescription filled in the states just to get the free month.
