Strips seem to work fine. The expiration is over a year out. The test strip indicator consists of Sodium Nitroprusside, which is sensitive to moisture and oxygen, so I recon storing them in small lots will prevent them from losing sensitivity and going grey like some people seem to have a problem with. I've divided the bottle into 5's and vacuum packed the strips, one with a pack of desiccant. We'll see how that does. At the very least, don't store these in the bathroom and open the bottle after a shower in a humid environment.

Definitely works. First strip is me dipping the strip in water and second strip is dipped in my fluid.

Keto stripes work as expected! Good price for quantity you get.

Thank goodness I have my old brand bottle so I can compare the colors which is more accurate and close to the colors that actually come on the stripsOverall, it’s still a good quality brand

Unfortunately, these had little to no color change from the time I opened the box. I've been tracking my macros and carb intake for the last month. I haven't had over 17 carbs the last month and still have had no color change. I should without a doubt be in ketosis at this point, so I'm thinking that the strips are defective. I'll be getting another test kit to verify, though, and will change my review if that one is also negative.

So in general urine test strips are not highly accurate for assessing mild to moderate ketosis. You can get a zero or 0.5 reading even when it should be much higher. If you do not know this, these test strips might confuse you. The results for me have been very inconsistent, and as someone trying to adjust my diet and react to what might be taking me out of ketosis. These test strips just do not provide me with results I can be confident in. The two test areas on each strip commonly read differently, the inner one seeming to react more and darken in color. The colors are difficult to distinguish from one another. I found that squinting and blurring my vision helps, while holding the strip up to the bottle to identify which band I match.I'll say this: If you get a 4.0 or higher using these test strips, you are certainly in ketosis. Anything less, you may or may not be in ketosis. If you are serious about the ketogenic diet, go ahead and spend more money for blood testing strips and a reader. These may confuse you more than they help you.

Works well

Test strips seem to do a good job indicating ketosis. Not much I can add to previous reviews other than sharing a visual of a strip that is 125 days after opening vs a strip a couple weeks after opening.The 90 day expiration is real. Results look different on older strips vs fresh strips.Overall I’m happy with product. I’ll buy another bottle in another 2 months.
