Bodypharm Melanotan II 20 Pen

The Body Pharm Melanotan II 20 Pen is a convenient, prefilled peptide solution designed to stimulate natural melanin production for a deeper, longer-lasting tan with reduced UV exposure. Each pen contains:20 mg Melanotan II

What does it do? 

• The Body Pharm 20 Pen delivers 20 mg of Melanotan II in prefilled form with no manufacturer-published mcg-per-click spec; you must back-calculate the dose from cartridge volume.
• A standard protocol uses three phases: tolerance (100 mcg daily for 3–5 days), loading (250–500 mcg daily for 1–3 weeks), and maintenance (100–250 mcg twice weekly).
• The pen format eliminates reconstitution and reduces waste compared to vials, but the side-effect profile (nausea, flushing, priapism, mole changes) is identical to vial-delivered MT-II.
• MT-II is unregistered with SAHPRA and unapproved by the TGA, FDA, and EMA as of 2026; regulatory status varies by jurisdiction and should be verified before purchase.
• Serious adverse events include priapism, melanoma induction, and neurological symptoms; dermatology screening before and during use is essential.

MT-II remains unregistered with SAHPRA as of 2026 [16] and unapproved by the TGA, FDA and EMA [5][8]. Read accordingly.

Who is this for? 

Those researching tanning and skin pigmentation.

How does it work? 

Melanotan II produces a tan by mimicking alpha-melanocyte-stimulating hormone and binding melanocortin receptors on melanocytes, which upregulates melanin synthesis (melanogenesis) and deepens baseline pigmentation. The pen format changes the delivery hardware, not the pharmacology.

The mechanism breaks down into four steps:

• MC1R binding in skin — MT-II is an analogue of α-MSH, so it activates MC1R on melanocytes and pushes them to produce more eumelanin (the brown/black pigment).
• UV is still required — MT-II amplifies the tanning response, it does not replace sunlight or a sunbed.
• MC4R activation in the central nervous system — the same peptide hits MC4R in the brain, which is why users report appetite suppression, nausea, and spontaneous erections within 1–4 hours of injection.
• Pen delivery is still subcutaneous.

How to use the pre-filled pen? 

Inject subcutaneously into the abdomen or outer thigh by pinching the skin, inserting at 90°, holding the dose button until the click stops, then counting three seconds before withdrawing. The prefilled cartridge skips the air-bubble purge that vial reconstitution requires, which is the main hands-on time saving over a 10 mg vial workflow.

Steps on a fresh pen:

• Inspect the cartridge through the window. The solution should be clear and colourless. Discard if cloudy or particulate.
• Attach a new pen needle (typically 4–8 mm, 31–32G) and remove both caps.
• Prime with one click into the air on first use to clear the needle dead-space. Subsequent doses don’t need re-priming the same day [1].
• Dial the target dose. Wipe the chosen injection site (lower abdomen at least 5 cm from the navel, or outer thigh) with an alcohol swab.
• Pinch a fold of skin, insert fully, press the dose button until it stops clicking, hold 3–5 seconds, then withdraw.
• Dispose of the needle in a rigid sharps container. Never re-cap by hand.

Possible side effects

• Flushing, nausea, darkening moles, priapism.

Storage instructions 

• Store the pen at 2–8°C between uses, upright, with the needle removed and the cap on.
• Do not freeze.
• Keep out of direct light.
