Some of my personal experience....
To
watchoutthegameisrigged who said he didn't want to keep trimix in the refrigerator cuz his wife might find it... uh, dude, a personal refrigerator is like $100, depending on size. You can find a place to hide it? I actually kept mine at work for a while, lots of folks at my office have personal refrigerators. But, I moved it home to a closet. I also keep some regular vitamins in it that my wife does know about. So, that provides cover for the trimix.
I would prefer not to have to have trimix. It does get you hard quick. But, it has some drawbacks. For one, it sometimes leaves my dick sore. And, once, I guess I hit a blood vessel or didn't inject it right and my dick didn't get hard, I just got some weird buldge on the side of the dick. The girl was not impressed, LOL.
My doc (at Men's Clinic of America) says I have venus leakage. Which sucks bigtime. It means the mechanism that helps hold the blood in the dick doesn't work right. He said the only cure is testosterone treatment. But I've been getting T injections for over a year and still have it. Sucks bigtime.
And, for all the people talking about how this or that OTC works great, well, if you got venus leakage, no, it does the fuck not. Well, it can help some. But, not enough. At least in my experience.
And, Yohimbe raises blood pressure pretty significantly. At least in a lot of people including me. So, don't take these OTC stuff if you don't know what you're doing or you have other significant health issues, which men with ED usually do.
But, another one of the OTC supplements that is supposed to help a lot is pycogenol tree bark. Didn't seem to help me though. But, it has overall other health benefits and few side effects. It doesn't raise blood pressure, for instance. But, its not a quick fixer. You are supposed to take it for an extended period of time. And its not a cheap supplement. Though not outrageous. So, if you are interested in OTC, you might at least research this one too. But as I said, definitely NOT a "before you bang" product.
