This was great advice. I went to my urologist and asked him if he heard of trimix. He laughed and said he coordinated it for his office. He gave me a script. I had it in a week. It cost $115 for one bottle which is about 30-40 doses. It worked great. I did not feel the needle. It was good for a 2 hr hard on. It was great and no side effects like the pills. If you need a longer hard on, you just take a higher dose.
