I don't have premium access but so many guys have questions about PDE-5 inhibitors ( Cialis, etc.) that I thought I would post it here. Now tadalafil (Cialis) is available in powder form as a generic. I know of at least one pharmacy in town that advertises 7 cent compounded tadalafil capsules. I won't post the name but will let you know by PM if you are interested. There may be others offering the same thing,, but I do know of this one.
Cialis is supposed to last for 2 days, but erections don't seem as strong as Viagra to me.
Some people stack them - take the Cialis for the time period you expect to probably need it, and then take the Viagra right before you know you'll need it.
Works pretty good for me, but might increase the risk of side effects, since that's an off-label practice. Not a doctor, just sharing what I've read about it.
