🔹 IN-DEPTH SCIENTIFIC PROFILE
Melanotan 2 (MT-2) is a synthetic peptide analog of the alpha-melanocyte-stimulating hormone (α-MSH), originally designed at the University of Arizona in the 90s as a strategy to prevent skin cancer by inducing endogenous tanning prior to intense sun exposure. Its affinity for melanocortin receptors surpasses that of natural α-MSH.
Molecular structure:
- Cyclic structure, which extends its half-life versus linear α-MSH
- Molecular weight: 342.4 Da
- High affinity for MC1R (melanogenesis) and MC4R (sexual function and appetite)
- Lower affinity for MC2R, avoiding adrenal activation
🔬 MOLECULAR MECHANISM OF ACTION
- Activación de MC1R en melanocitos: stimulates the synthesis of eumelanin, the pigment responsible for dark colour and UV protection
- Activación de MC4R hipotalámica: reduce apetito y modula función sexual central
- Reducción de inflamación cutánea: side effect related to its kinship with α-MSH
- Modulación de termogénesis: mild impact on basal energy expenditure
🧪 RESEARCH APPLICATIONS
- Safe tanning prior to sun exposure (original primary research)
- Erectile dysfunction resistant to PDE5 inhibitors
- Female sexual desire dysfunction
- Vitiligo (repigmentation research)
- Weight loss in preliminary research
💉 RECONSTITUTION PROTOCOL
Reconstitution: 2 ml of bacteriostatic water in a 10 mg vial. Concentration: 5,000 mcg/ml.
⚠️ SAFETY CONSIDERATIONS
Common adverse events: nausea (especially first doses), facial flushing, increased libido, darkening of pre-existing moles, appearance of new moles.
Punto crítico: dermatologically assess any new mole or change in existing moles during and after the protocol. Generalized melanocyte stimulation may darken pre-existing pigmented lesions, which could mask or mimic neoplastic changes.
Contraindications: active or suspected melanoma, family history of melanoma without prior dermatological evaluation, pregnancy and lactation.
🧬 STACK AND COMBINATIONS
- MT-2 + PT-141 for comprehensive sexual function coverage (complementary mechanisms)
- MT-2 + GHK-Cu for skin support during pigmentation
