I did use Cialis in the past, took a pill daily, but never got to a point where I found a "right" level. Curious to hear about this too.
When in Asia, I get Kamagra gel packs by the box (100mg of Sildenafil in each packet - and 50 packets total per box) and that stuff is potent. After going on TRT, I no longer have any issue with getting good wood, but for more fun I like to pop a packet. And after 100mg of the Kamagra, damn, Mr Johnson gets both bigger and becomes semi-metallic in rigidity. It's noticeable. Good stuff that, I can feel the effect the following morning too, so I think at least for me, the effects last longer than the claimed 3-4 hours.
I've asked a lifting buddy who lives in Asia if he knows of any generic version of Cialis (i.e. tadalafil).
