I've been making my own eye drops with this and so far so good. For price comparison, 10ml of eye drops cost $15-30 and contain .1gram of NAC. I bought the 10 gram bulk NAC powder and that will make 1000ml of eyedrops of the same strength. So for about $30 you get the equivalent of $2-3000 worth of NAC eyedrops.

I bought this product also bought 18/8 stainless steel measuring spoons. used smallest spoon to achieve the correct dosage of this product per 1 oz of distilled water and very very small amounts of himalayan pink salt only to correct ph of distilled water. used smallest spoon of N-Acetyl L-Carnosine per 1 oz of distilled water only. this is your eyes!!! you are dealing with!!! THE HIMALAYAN PINK SALE HAS TWO FUNCTIONS. First function "to correct the ph of the distilled water to match the ph of your eyes. so the distilled water dose not burn or irritate your eyes." second function "to act as a preservative." keep everything sterile. use 2 oz dark brown glass bottle and dropper only. keep away from sunlight.

The product itself is amazing. Reduction in cortisol and feelings of stress, depression, and anxiety, all backed by research. This impacts GABA.<br /><br />I am an ICU nurse and work in a high stress environment, and with this supplement I feel something that is different than anything I've tried in the past. It's hard to put my finger on, but it's very nice. It keeps me calm and happy.<br /><br />The packaging got 4 stars. This is a bag within a bag, and the inside bag holding the carnosine was open.

I ran out of 25 g size, and no availability on my last bottle of drops, and this finally showed up again in the mega size. If you have halos or haziness around bright objects or are getting blind flashes by oncoming car headlights or have been told you have "baby" or "immature" cateracts. First get screened for diabetes and treated if you have it. Second get this powder in the 10 or 25 gram size, if you can. Third, find a food scale that will measure tenths of a gram. Fourth, get 30 cc dropper bottles from pharmacy or Amazon. Fifth, measure 0.6 grams onto a clean tared (reset to zero with paper on the scale) paper, using tiny portions from a small spoon or knife. Crease one side of the paper. Dump into the dropper bottle, and add sterile water to the curve in the brown bottle. Squirt and fill the dropper until all the white stuff is gone. This is a ballpark 2% solution. Look at a bright light against a dark background. Hold your hand out to measure the size of the flare around the light. Try the other eye. Take 2 drops each eye morning and night. That flare should get somewhat smaller within a month, and your night headlight blindness should get a lot better. Otherwise time to see the ophthalmologist. If the treatment is working, continue it, and do not stop. It regresses the density of a cateract but does not eradicate it in randomized trials, including one in my eyes - don't bother with yours as my left eye was the control and never caught up with the improvement I got on the right. For me, continued treatment arrests them whereever they got to with the starting treatment. I am still 20/20 with correction at 74, and 20/15 on the right.<br />NOTE: If you cannot correct to 20/40 in normal light cateract surgery or other treatment may be in your best interest.<br />NOTE: If your senior dog or cat has a gray or filmy look in his or her eyes when you shine a flashlight from the side, this stuff will probably also work. This stuff was studied extensively by only one guy, a Russian physician, and his data were very convincing. My own personal experience, and that of my wife and a growing number of friends and relatives, bears those data out.<br />NOTE: If the bottle gets coudy or stringy, trash it and make another batch. This is most likely fungus. Use a fresh bottle for each batch. I am just trying putting the powder in multiple bottles and mixing them up with sterile water - boiling and cooling should be fine - when needed. I do not sell anything. These statements have not been reviewed by the FDA or any ophthalmologists. Jim Smeltzer, MD

This is a very low dose supplement.when i opened the sealed plastic pouch i saw loose white powder and also another clear plastic containor with white powder. I attempted to contact seller to ask why there was 2different sources of white powder.manufacturer has no cust.or technical service contact number.from the high price of this product i wouldnt recommend the purchse of this product from this seller manufacturer.

Vendor stopped shipment due to a price increase. Greedy. Will not buy from BulkSupplements again. My last product from them was contaminated with dessicant crystal balls
