I have just ordered NADH (six boxes) Rapid Energy release and am a repeat customer. This product is like a wonder drug and can only be bought from the Finchley Clinic. I have managed to finally get myself off a prescription drug addiction after 12 years, without any additional help. It is quite an unbelievable product. I have a science background so I fully understand how this works in the body, it isn't a drug, it's a naturally occurring product of cellular respiration (a much abridged description). I have had NADH intravenously in very high doses and it made me very ill. I have also got the nasal spray but these tablets are by far the better and cheaper option in my opinion. If they got me off prescription strength painkillers after 12 years of addiction (without any withdrawal effects at all and I went from heavy usage to zero usage in two weeks), imagine what they could do to an ordinarily fit and healthy person? I will be taking these for the rest of my life!!
