Dr. BozPucker UP! Clear Ketones, 20 Packets - Pure Liquid BHB - Fast Acting Exogenous Ketones - Increase Energy & Clarity - Max Strength - Quality Tested - Made in USA - Keto Diet - 0.34oz (10ml)

Amazing! I mix this in with my electrolytes & sparkling mineral water during prolonged fasting - LOVE the tartness, increased energy and decreased hunger making it a wonderful tool during fasting!

If your having trouble producing ketones, try this product! It is expensive, but wow it works! It is pretty sour tasting, but if you have been on a super strick keto diet for awhile (like a year or more), it may not seem that sour. I have been eating a keto (almost carnivore) diet for over 2 years now and the sour, tart taste of Dr. Boz's Pucker Up is not that tart to me anymore. It helps me keep my ketones up and definitely gives me energy when I'm in a afternoon slump. It has pure ingredients with no extra fillers or artificial sweeteners, and it mixes easily into water.

Love this product. It's the cleanest on the market without all kinds of added alternative sugar and flavors. Love the new packaging too because it's easier to open

I use these whenever I'm fasting, or whenever I need to recover quickly from falling off the low-carb wagon. Pucker Ups are amazing. Only ketones. No "fat" to worry about. No bowel issues. Just energy. It's really tart so put it in something a little sweet. I don't do "sweet" anymore because I'm trying to avoid anything that makes me hungry or makes insulin flow. But a little sweetness counteracts the extreme tartness of the PuckerUps.

Not in ketosis — not within an hour (or three) after use, and not after 3 days of regular use and a keto diet. Don’t waste your money, these aren’t effective.

I absolutely love Pucker Up! Dr. Boz's raspberry lemonade ketone powder is good, but I really prefer these sour ketones. I mix a packet in a can of sparkling water and sometimes add a couple fresh cherries. Ketones jumpstart weight loss for me when I've hit a plateau.

I have been practicing the ketogenic lifestyle for almost ten years. All of Dr Boz products are the best and deliver great results. This product is great for adding to sparkling water for a quick midafternoon pick me up if keto food is not available. Great for traveling!

I would give this product 5 stars if it was not so expensive.
