My regimen is: 1/6 Proscar daily
2x 5% minoxidil daily (usually the foam)
5% spironolactone (Dr Lee's) 1X daily (sometimes twice daily)
Copper peptides (Tricomin or AC) after shower
I also take various supplements such as fish oils, MSM, GTE, and biotin, but I don't really consider these part of my core regimen and wouldn't be the least concerned about dropping them. I probably wouldn't be too concerned with dropping the CP's either. I would never quit finasteride, minoxidil, or spironolactone at this point.
