What is Melanotan-II?

Melanotan-II is a research peptide in the Body Recomposition class. Non-selective melanocortin agonist; studied for melanogenesis. It is studied at per-dose ranges of 250–500 mcg / day (loading) (Variable weekly), administered daily sc during loading over cycles of 2 weeks loading + maintenance. Supplied in Thailand by Thailand Peptides — Bangkok-based, research use only.

Synthetic melanocortin-receptor agonist. Research use only; multiple off-target MC-receptor effects.

Published and preclinical data are summarised below; dose ranges shown reflect protocols in the research literature and should be interpreted accordingly.

How does Melanotan-II work?

Primary mechanism: Non-selective melanocortin agonist; studied for melanogenesis. Research on Melanotan-II implicates downstream effects on related signalling cascades, with magnitude and clinical relevance dependent on dose, timing, and individual pharmacogenomic factors.

Receptor binding affinity and post-receptor signalling for Melanotan-II remain areas of active investigation; several proposed effects within the Body Recomposition class are currently supported only by in-vitro or rodent data, and should be interpreted accordingly.

Melanotan-II dosage & protocol

Reference protocol for Melanotan-II (research context only, drawn from published literature):

  • Per dose: 250–500 mcg / day (loading)
  • Weekly total: Variable
  • Frequency: Daily SC during loading
  • Cycle: 2 weeks loading + maintenance

Stacking Melanotan-II

Commonly referenced pairing with Melanotan-II: Monotherapy. Stacking rationale should be grounded in complementary mechanisms, not additive speculation; interactions at shared receptors or enzymatic pathways should be accounted for. Both compounds in a Melanotan-II stack are supplied by Thailand Peptides on the same order via the Bangkok research desk.

Contraindications

Atypical moles, melanoma history. Additional caution is warranted in individuals with hepatic or renal impairment, endocrine disorders, or concurrent pharmacotherapy affecting the pathways described above.

Melanotan-II — common questions

What is Melanotan-II and what is it used for in research?
Melanotan-II is classified within the Body Recomposition group. Synthetic melanocortin-receptor agonist. Research use only; multiple off-target MC-receptor effects. Research applications focus on the pathways outlined below. All references on this page describe published research only — Melanotan-II is supplied for in-vitro and laboratory use, not for human consumption.
How does Melanotan-II work?
Primary mechanism: Non-selective melanocortin agonist; studied for melanogenesis. Downstream effects depend on dose, timing, and the biological system under investigation. Receptor binding and post-receptor signalling for Melanotan-II remain areas of active study, and several proposed effects are supported only by preclinical data.
What is the typical Melanotan-II research dose?
Published research protocols for Melanotan-II describe per-dose ranges of 250–500 mcg / day (loading), with a weekly total near Variable, administered daily sc during loading. Typical cycle: 2 weeks loading + maintenance. These ranges reflect the literature and are not dosing recommendations for any individual.
