How it works
Both peptides act through melanocortin receptors; the stack delivers both targeted libido effect (PT-141, primarily MC4R) and broader melanocortin activation (MT-II).
Protocol notes
PT-141 1–2 mg as-needed before activity; MT-II 250–500 mcg during tanning-loading or maintenance phase. Caution combining due to overlapping side-effect profiles.
Reported side effects
Stacked side-effect profile: nausea, flushing, blood pressure changes, mole changes.
