Seems like a bunch of us are in the same boat - working to return to our former selves. On my own journey, Reta and testosterone have been amazing, and other improvements came along with them. I've experimented with pr*mo, m@st, tr*n, MOTS-C, MT2, NAD+, CJC, HGH, glutathione, L-carn...seeing it typed out makes it seem ridiculous! GLPs and oils both appear to genuinely help, and at this point I'm simply attempting to share what I've learned.
