I don't think there is a definitive answer--it depends on each individual. I first used it more than five years ago, and had to use it again after six months. Since then, I've only had to use it twice to maintain.

I suspect it will be bad news. I would test it for at least a month. (It is pretty slow acting.)

I think about a year. This product is excellent...if taken every day...you will finish the bottle within three months.

you can purchase a 30 day or 60 day supply and they do last about that long. The results, in my opinion, lasts as long as you continue the process correctly.

I am unsure, we have never had that challenge. My wife takes these every day. I don't have our bottle in front of me, but my guess would be about 6 months to a year. Maybe you can ask the manufacturer? Good Luck!

It helps if you use everyday and follow instructions, results show in about 3 to 4 months

That's hard to say exactly. If you use a couple of drops each time (like it recommends) it should last for months, or longer.

I would estimate 2-3 months from my personal experience. But really depends on how generous, or conservatively you apply it.

I've been using mine already for 3 months, and there's still a lot of product there. I apply it once in a day.

Im sorry, I don't think that there is... but if you apply it as recommended, you shouldn't own it for more than a few months.

A little bit more then a month depending on the amount you use. I would say something around a month. But it works miracles!

Some have claimed to see a result as quick as one month. Yet the company and physicians will say to give it three months as that is how long a "man's supply" takes to "cycle through" so to speak. Don't want to be discouraging, but unfortunately this product never worked for us with a continuous 9 months of use (we had semen washes done every month so we know it actually didn't work)

I can not fully answer your question. After three weeks of using this product, I have seen little progress toward successfully achieving the claims made by this product. Perhaps after more prolonged use, I will see better results. At the same time, I have seen no reason to believe the hoped for results may be achieved with a longer term of use. Ambiguous answer? You couls call it that.

I have two answers. First, try to get a really solid answer by calling Optigard.! Second, I use it twice a year or more, and my remaining supply seems just as potent a year later. Very good product in any case. T LeMay

I have had it for about 6 months.I use it and there is an immediate noticeable affect. It is not a magic pill or sales gimmick. Skepticism is in all of us. Go with your own gut, weigh the reviews with wisdom make your decision and use the product.I have not sent mine back and I wont. Since every individual responds differently to this product keep in mind you may not have the same results as mine or other claims. But you are the best judge of that. HOPE this helps you whatever you decide.
