Ultima-MT-1 contains Melanotan I (MT-1), a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH). It is primarily associated with stimulating melanin production and supporting pigmentation, making it particularly interesting for tanning, skin-pigmentation, and melanocortin-focused research.

How it works

Melanotan I interacts primarily with melanocortin-1 receptors (MC1R) found on melanocytes. Activation of these receptors stimulates the production of eumelanin, the darker form of melanin responsible for much of the skin’s tanning response.

By promoting melanin production, MT-1 is studied for its ability to enhance pigmentation while working through pathways naturally involved in the body’s response to UV exposure.

Proper Use and Dosage

The listed product contains 10 mg (10,000 mcg) per vial.

Commonly referenced MT-1 research protocols use 0.5–1 mg per administration, with frequency adjusted according to the desired pigmentation response. Some protocols begin with more frequent administration during an initial pigmentation phase before transitioning to less frequent maintenance use.

At 0.5 mg per administration, a 10 mg vial provides approximately 20 administrations. At 1 mg per administration, it provides approximately 10 administrations.

For tanning-focused protocols, MT-1 is generally used consistently over a defined period while pigmentation develops, followed by less frequent maintenance administration.

Benefits

Ultima-MT-1 is particularly suited to applications involving melanin production, tanning, pigmentation, and melanocortin research.

Key benefits and areas of interest include:

• Stimulates melanin production
• Supports increased skin pigmentation
• Promotes eumelanin formation
• Supports tanning-focused protocols
• Targets the MC1R melanocortin pathway
• Provides research interest in pigmentation biology
• May support a more noticeable tanning response
• Can complement controlled tanning routines
• Provides a concentrated 10 mg presentation

MT-1’s more targeted activity at the MC1R pathway makes it particularly interesting for individuals focused primarily on pigmentation and tanning-related applications.

Side Effects

Possible effects may include nausea, flushing, headache, dizziness, fatigue, changes in appetite, and injection-site irritation. Increased pigmentation of freckles or existing pigmented areas can also occur.
