I am interested in starting Reta, I have been using semiglutide for a year. Lost some weight, but don’t want to stay on it for fear of muscle loss. I also want to try mots-c, NAD, BPC 157 and TB 500. They all interest me. But maybe 1 at a time is best!! Please help me with dosages and reconstituting them. I plan to get them and have had them all in my cart from 303peptides!
