It’s important to understand that Melanotan 2 (MT2) is a potentially unsafe and unregulated substance, and I cannot provide specific medical advice on its use.

However, I can share some general information about its potential duration of effects:


  • The initial darkening of the skin can occur within 6 days of initiating MT2 injections.
  • The desired tan level is typically achieved within 2-4 weeks of regular injections.
  • Once you reach your desired tan, maintenance injections can be administered less frequently (up to twice weekly) to maintain the tan for weeks or months.
  • However, the tan itself will gradually fade if injections are stopped, with the rate depending on individual factors like metabolism and sun exposure.

Other effects:

  • MT2 also has other potential effects, such as increased libido and appetite, as well as side effects like nausea, flushing, and darkened skin. These effects may also vary in duration depending on individual factors and dosage.

Important Considerations:

  • MT2 is a synthetic peptide not approved for any medical use in many countries, including the USA.
  • Its long-term safety is unknown, and potential risks include increased risk of skin cancer, heart problems, and other serious side effects.
  • Using MT2 without medical supervision is strongly discouraged due to the risks and lack of reliable information about its long-term effects.


If you are looking for a safe and effective way to achieve a tan, there are many safer alternatives available, such as:

  • Sunless tanning lotions: These lotions contain chemicals that react with your skin to produce a tan color.
  • Spray tans: A professional sprays a mist of tanning solution onto your skin, which then develops into a tan.
  • Basking in the sun with proper UV protection: This is the most natural way to tan, but it’s important to use sunscreen to protect your skin from harmful UV rays.

It’s important to consult a healthcare professional before considering any tanning methods, especially if you have any health concerns.

I hope this information is helpful. Please remember that I cannot provide specific medical advice and encourage you to seek professional guidance for any questions or concerns you may have about MT2 or other tanning methods.

How Long Does Melanotan Take To Work?

Melanotan 2 (MT2) is a synthetic peptide that stimulates the production of melanin, the pigment that darkens your skin. It’s often used for tanning, but it’s important to note that MT2 is not approved for any medical use in many countries, including the United States.

Here’s how long MT2 takes to work:

  • Initial darkening: You may start to see a slight darkening of your skin within 6 days of starting MT2 injections.
  • Desired tan: It typically takes 2-4 weeks of regular injections to achieve your desired tan level.
  • Maintenance: Once you reach your desired tan, you can space out your injections to 1-2 times per week to maintain the tan for weeks or even months. However, the tan will gradually fade if you stop injections.

It’s important to remember that everyone’s body is different, so how long MT2 takes to work for you will vary depending on factors like your metabolism, skin tone, and sun exposure.
