@doblack50 Now that I think about it the BCP-157 was subcutaneous and I tried NAD+ IM. NAD+ is like $350 and has a shelf life of 2 weeks. Most of the people selling peptides will include a lab analysis with the batch. I am pretty desperate to try anything to make the ringing in my head go away. It is a good idea to keep a log book of what you take date, time and dosage.
I hope it helps and would be interested in hearing about it if successful.
