Tadalafil
"57 YOM. Taking Cialis/Tadalafil for 3 years & it has changed my life, my wife's life & our marriage for the better. My weak/sporadic erection issues started 4-5 years ago; felt like woody had a perpetual leak. Tried exercise, ginseng, nuts, avocados, oysters etc. with little success. Very frustrating for me & my wife.Decided to see an MD when my wife could not get me hard with oral sex. MD gave me a quick physical/blood test, then he gave me 2 10mg and 30 5mg cialis samples.He told me to take the 10mg on my Friday night & have fun. Wow, was he right! Having rock hard wood & great sex (oral, front or back door) with my wife ever since. Take 2.5mg (breaking 5mg in half) every night before bed with no side effects except great sex!  Good luck!"
