That low amount of NAD+ is negligible. So you wont notice a difference. A therapeutic amount of NAD+, especially to cycle up in the beginning, is 750mg a day for the first week, then 750mg a week to two weeks. Personally i dont think 20mg twice a week will do anything. It wont hurt but i think its just a reason to charge more for a product that will give no added benefit. I get my LIPO-C in a 20ml bottle for about $50-60 and thats 5 months worth and it works great. I use it in conjunction with MIC-B12 (0.5ml twice a week for each MIC and LIPO). Brings back my energy and drives away the fatigue of tirz. But have now found 5mg of SS-31 and 5mg Epitalon every other day gives me WAY more energy and its way more natural and beneficial. Ill keep using the MIC & LIPO as it wont hurt but really like the SS-31 & Epitalon. After about 8 weeks I’ll switch the SS-31 to MOTS-C for 8 weeks. I think its a better long term fix than the MIC & LIPO
