Hi Khanh,
Recently I am using a NAD+ 250mg SQ injection-1cc from Meta Pharmacy from Las Vegas, NV. IT has some other things in it such as BCAA, taurine, methylcobalamin. I didn’t have a reaction or feel that uncomfortable feeling you get with IV and the TMC patch. I tried it to and NO WAY will I give that to a patient.
I think it is called NAD+ Limitless SQ injection. They have different strengths but after my experience with TMC product I chose the lowest dose.
