Level
Intermediate

Very short-acting — protocols dose 1–2× a day. After the last dose, roughly 97% has cleared in ~5 h (five half-lives) — the window that matters for washouts, bloodwork and surgery.

What Melanotan II is used for

  • Tanning effect (skin pigmentation increase) is the headline signal
  • Libido / sexual response effects (related to PT-141)
  • Visible result within weeks

How it's typically used

Loading: 0.25 mg subq daily ~7–10 days. Maintenance: 0.5 mg once or twice weekly.

What to watch for

  • Darkened or new moles — monitor and biopsy if changing
  • Nausea, flushing, appetite loss are common
  • Concerns around unsupervised melanocortin activation; not a casual peptide

About Skin, hair & aesthetic

What they are
Skin, hair, and pigmentation compounds — some injected, some formulated into topicals.
How they're run
Topicals go on clean skin daily; injectables run in short courses. Either way the timescale is months.
What to watch
Melanocortin compounds darken existing moles and can trigger nausea and flushing — get a skin check before and during. Topical peptides are cosmetic and act only where applied.
