Melanotan II 10 mg — Tanning & Libido Research

Protocol

Reconstitution & Usage Protocol

Important: Only chill the water for 3 minutes before reconstituting the peptide. Do not prepare with very cold water, because it may freeze, lose its effect, or become damaged.

1Reconstitution

Materials: 1 vial of Melanotan II 10 mg · 1 vial of bacteriostatic water · U-100 insulin syringe · 3 mL syringe · alcohol wipes.

Let the vial reach room temperature for 10–15 minutes.
Disinfect the rubber caps with an alcohol wipe.
Draw 4 mL of bacteriostatic water with the 3 mL syringe in 2 successive draws.
Inject the water slowly down the inner wall of the vial.
Do not shake. Swirl gently until the solution is clear.

Label with the date and refrigerate (2–8 °C). Stable for 28 days.

2Concentration & Dosing

Reconstituting 10 mg in 4 mL → 2.5 mg/mL = 25 mcg per IU.

Target dose	Units	Volume
250 mcg (initial)	10 IU	0.10 mL
500 mcg (standard loading)	20 IU	0.20 mL
1 mg (high maintenance)	40 IU	0.40 mL

Universal formula: IU = (dose in mcg ÷ 25)

3Application

Route

Subcutaneous in the abdomen.

Frequency

Loading phase: 250–500 mcg daily until the desired tone is reached (2–4 weeks). Maintenance phase: 500 mcg – 1 mg, 1–2 times per week + sun exposure or controlled UV booth.

Cycle

A 2–4 week loading phase until the desired tone is reached, followed by maintenance at 500 mcg – 1 mg, 1–2 times per week.

Caution: do not combine with intense sun exposure without protection; monitor moles (annual dermatological review recommended).
Before applying: let the drawn dose lose its chill (only the amount to be injected) — hold the syringe in your hand for 2–3 minutes.
After applying: gently massage the area for ~40 seconds to disperse the peptide and improve absorption.

Importante: Solo poner a enfriar el agua 3 minutos antes de reconstituir el péptido. No preparar con agua muy fría, porque se puede congelar, perder efecto o dañarse.

3Aplicación

Vía

Subcutánea en abdomen.

Frecuencia

Fase de carga: 250–500 mcg diarios hasta alcanzar tono deseado (2–4 semanas). Fase de mantenimiento: 500 mcg – 1 mg, 1–2 veces por semana + exposición solar o cabina UV controlada.

Ciclo

Fase de carga de 2–4 semanas hasta alcanzar el tono deseado, seguida de mantenimiento con 500 mcg – 1 mg, 1–2 veces por semana.

Precaución: no combinar con exposición solar intensa sin protector; monitorear lunares (revisión dermatológica anual recomendada).
Antes de aplicar: dejar que la dosis cargada pierda el frío (solo la cantidad a inyectar) — sostener la jeringa en la mano 2–3 minutos.
Después de aplicar: masaje suave en la zona durante ~40 segundos para dispersar el péptido y mejorar absorción.

Important : Ne mettre l'eau à refroidir que 3 minutes avant de reconstituer le peptide. Ne pas préparer avec de l'eau très froide, car il pourrait geler, perdre son effet ou s'abîmer.

1Reconstitution

Matériel : 1 flacon de Melanotan II 10 mg · 1 flacon d'eau bactériostatique · seringue à insuline U-100 · seringue de 3 mL · lingettes d'alcool.

Laisser le flacon revenir à température ambiante 10–15 minutes.
Désinfecter les bouchons en caoutchouc avec une lingette d'alcool.
Prélever 4 mL d'eau bactériostatique avec la seringue de 3 mL en 2 prélèvements successifs.
Injecter l'eau lentement le long de la paroi intérieure du flacon.
Ne pas secouer. Faire tourner doucement jusqu'à obtenir une solution transparente.

Étiqueter avec la date et réfrigérer (2–8 °C). Stable 28 jours.

3Application

Voie

Sous-cutanée dans l'abdomen.

Fréquence

Phase de charge : 250–500 mcg par jour jusqu'à atteindre la teinte souhaitée (2–4 semaines). Phase d'entretien : 500 mcg – 1 mg, 1–2 fois par semaine + exposition solaire ou cabine UV contrôlée.

Research Highlights

As an α-MSH analog, Melanotan II is studied for its activation of melanocortin receptors and stimulation of melanin production, generating a protective tan against UV radiation with reduced sun-exposure time in research models.
Through its action on central melanocortin receptors, the compound is reported to increase libido and improve sexual function as a desirable secondary effect in study settings.
Research also associates Melanotan II with mild appetite suppression and positive secondary effects on the metabolic profile, attributed to its central melanocortin activity.

FAQ

Frequently Asked Questions

What is Melanotan II and how does it generate a tan in research models?

Melanotan II is a synthetic analog of the α-MSH hormone that activates the melanocortin receptors and, in study models, stimulates melanin production to generate a protective tan against UV radiation. Its action on central receptors also accounts for reported secondary effects on libido, mild appetite suppression, and the metabolic profile. It is supplied strictly for in-vitro and laboratory use.

How is the 10 mg vial reconstituted and what concentration results?

Reconstituting 10 mg in 4 mL of bacteriostatic water yields 2.5 mg/mL, equal to 25 mcg per IU on a U-100 insulin syringe. Chill the water for only 3 minutes before use, inject it slowly down the inner wall, do not shake, and swirl gently until the solution is clear. Label, refrigerate at 2–8 °C, and the solution is stable for 28 days.

What dosing schedule is described in the research protocol?

The protocol describes a subcutaneous abdominal route with a loading phase of 250–500 mcg daily (10–20 IU) until the desired tone is reached over 2–4 weeks, followed by maintenance of 500 mcg – 1 mg, 1–2 times per week, paired with sun exposure or a controlled UV booth. Using the formula IU = (dose in mcg ÷ 25), 250 mcg is 10 IU (0.10 mL), 500 mcg is 20 IU (0.20 mL), and 1 mg is 40 IU (0.40 mL). These figures describe laboratory parameters only and are not human-use instructions.

What handling precautions are noted for Melanotan II?

The reference notes not to combine the compound with intense sun exposure without protection and to monitor moles, with an annual dermatological review recommended. Before applying, let only the drawn amount lose its chill by holding the syringe in hand for 2–3 minutes; after applying, massage the area gently for about 40 seconds to disperse the peptide and improve absorption. All use is strictly for in-vitro and laboratory research, not for human or veterinary administration.
