Melanotan II is primarily administered via subcutaneous injection, which is favored for its high bioavailability and direct action on melanocortin receptors, leading to effective tanning and libido enhancement [Doc 1, Doc 2]. While oral administration is theoretically possible, it is ineffective due to degradation in the digestive tract [Doc 3]. The peptide is often used in cycles to prevent tolerance, with users typically starting at low doses and gradually increasing [Doc 2]. The peptide is available as a lyophilized powder that must be reconstituted with bacteriostatic water before injection [Doc 1].
Subcutaneous Injection
Subcutaneous injection is the preferred route for Melanotan II due to its high systemic bioavailability and direct activation of melanocortin receptors, which are responsible for increased melanin production and libido enhancement [Doc 1, Doc 2]. This method involves injecting the peptide under the skin, typically in areas with sufficient subcutaneous fat like the abdomen or thigh [Doc 3]. The injection is usually performed with an insulin syringe, and users are advised to rotate injection sites to avoid tissue irritation [Doc 1]. A typical protocol starts with a low dose of 0.25 mg daily, gradually increasing to a maximum of 1 mg daily over several days to minimize side effects such as nausea and flushing [Doc 2].
| Phase / Protocol | Dosage | Frequency |
|---|---|---|
| Days 1-3 | 0.25 mg | daily |
| Days 4-7 | 0.5 mg | daily |
| Day 8+ | 1 mg | daily |
