Melanotan II vs Lactoferricin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Melanotan II
Melanotan II is a synthetic peptide analog of α-MSH with broader receptor activity than Melanotan I. It produces tanning effects and has notable effects on sexual function and appetite suppression.

Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.

| Aspect | Melanotan II | Lactoferricin |
|---|---|---|
| Mechanism | Non-selective melanocortin receptor agonist affecting MC1R (tanning), MC3R and MC4R (sexual function and appetite). This broader activity explains its multiple effects beyond tanning. | Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. |
| Typical Dosage | Typical protocols: 0.25-0.5mg daily during loading phase for 1-2 weeks, then 0.5-1mg before UV exposure for maintenance. Start low to assess tolerance. | Research applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. |
| Administration | Subcutaneous injection. Usually combined with UV exposure for tanning effects. Nasal spray formulations exist but have lower bioavailability. | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. |
| Side Effects | Nausea (common initially), facial flushing, spontaneous erections, increased libido, appetite suppression, and mole darkening. | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. |
