Cialis doesn't really do much for me. 100mg of Viagra keeps me going through the night, into the morning. Right now I'm taking 25mg Liquid Cialis, 50mg Viagra and 0.5mg Liquid Prami. Once a week, I'll take iPT-141 and Melanotan 2 before tanning. I'm harder then a rock when ever and can keep going for as long as my endurance will allow. I used to not be able to keep up with my fiancee, now she can't keep up with me.
