Lost 38lbs so far!!! Great test to Keep you on Track!!
These ketone strips help you stay on track with your ketogenic diet. I’ve been using them everyday since I received them. If the color goes to light of purple I cut back on any carbs. Limit if 25-30g per day. If the color goes too dark I increase my water intake. So far I have lost 38lbs. My goal is 45 before my 45th birthday in July. Feb 16th I was 234… today April 27th I am 196…just over 2 months. Keto really works if you stick to it!!!!

It Works
First test worked great. Clear color signal confirmed I'm in ketosis.

Not reliable at all
I purchased these as a cheaper alternative to another brand I have from my doctor. I tested them thoroughly and discovered they were not reliable at all. My bottle stated the expiration was not until 2027. First test: While late into fasting, I compared these strips with those I received from my doctor. These showed no indication of ketones. Second Test: I repeated the first test at a later time. Same failed result! Third Test: I used 4 of these strips on the same urine. Two had no indication. The other two had inconsistent color change. The purpose of buying this product is to reliably detect ketones. This product cannot be relied upon to meet its intended purpose. I would not recommend this product to anyone. They have no value.

Dissatisfied
Strips always show the same color. They don’t seem to be working. I’m eating less than 30 carbs a day and noticeably losing weight. Maybe I’m not in ketosis, but each test strip shows the same .05 every time. Dissatisfied. I can’t tell if they work or not.

Different versions on big and bottle
The colors on the two tests were slightly different (one level different 1.5 and 4.0)when I used them for the first time this morning. So I assume they work pretty well. I will be using them for a five day fast ( starting today). The only issue I see is the box says upgraded version 3.0 and the bottle says upgraded version 2.0. Maybe one is a typo?

Work Great. Seem to be very accurate.
These work great. I can see they work correctly because it showed high Ketosis then I had a cheat meal and it's back to showing me out of Ketosis. Then I watch Ketosis slowly start again as I am strict with my carnivore diet and they're fully registering Ketosis around the 4th day. One day I had been super strict with absolutely zero carbs for a few days and felt like death. I said I am probably in the highest Ketosis judging by my eating and how I felt. I did the test and sure enough its really dark red meaning super high Ketosis. I just said "Yep, that's why I feel like I'm dying" (attached that photo). So they are consistent with how I eat and feel, so I know they are accurate and I am losing weight quickly. One cheat meal and it knocks me out of Ketosis as expected. It helps me not to cheat, because I see by the tests that I take 4 days to fully enter ketosis again. No cheat carb is worth the 4 days to re-enter ketosis. The only drawback is once you open it they only last about a month, so take as many tests as you want, because they will expire quickly.
