🧬
Basic Introduction
MT-2 is a potent synthetic analog of endogenous α-MSH. Native α-MSH has weak bioactivity and extremely short half-life; the cyclized structure of MT-2 drastically elevates receptor binding affinity, continuously activates melanocortin receptors MC1, MC3, MC4, MC5 distributed across skin, eyes and reproductive tissues.
Core pathway: Activate MC1 receptors to trigger melanin synthesis in melanocytes for UV-free tanning; simultaneously central MC3/MC4 receptor modulation improves libido, suppresses appetite, exerts anti-inflammatory and antioxidant effects.
Different from topical tanning creams that only stain the epidermis, MT-2 fundamentally stimulates melanocyte proliferation and melanin production to build long-lasting even bronze skin tone, with secondary benefits including libido enhancement, appetite suppression and anti-inflammation.
Critical Safety Notice: No complete long-term human clinical safety data exists. Unauthorized self-injection carries risks of abnormal pigment proliferation, endocrine disorder and cardiovascular stimulation. It is only permitted for in vitro cell and preclinical animal research.
What is MT-2 / Melanotan 2 Acetate?
🛡️
UV-free safe tanning avoiding sun damage
Conventional tanning relies on UV radiation, long-term overexposure raises risks of melanoma and photoaging; MT-2 endogenously stimulates melanin production to build even tone indoors, drastically cutting skin lesion risks.
✨
Long stable skin tone superior to topical tanning lotions
Topical self-tanners only stain dead epidermis and wash/flake off quickly; MT-2 modulates melanocyte activity with dermal pigment deposition that fades gradually over months.
⚛️
Multi-benefit single peptide: Tanning + appetite control + libido boost + anti-inflammation & antioxidation
One peptide delivers combined improvements in skin tone, fat loss support, sexual function and cutaneous repair with synergistic multi-pathway effects.
⚖️
Mild metabolic improvement to amplify fat loss with GH secretagogues
Suppresses hunger and accelerates lipolysis; stacking with GH-releasing peptides further enhances visceral fat breakdown and body recomposition.
⏳
Anti-inflammatory relief for sensitive skin & post-sun repair
MC3 anti-inflammatory cascade relieves skin redness, acne and UV burn inflammation, combining repair and tanning functions simultaneously.
🔬
Chemical Classification
Synthetic cyclic decapeptide analog of α-MSH (alpha-melanocyte stimulating hormone), acetate stabilized form
Mechanism of Action
- MC1 Receptor Activation (Core Tanning Pathway)Bind MC1 receptors on dermal melanocytes under epidermis, upregulate tyrosinase (rate-limiting melanin synthesis enzyme) activity to accelerate conversion of tyrosine into eumelanin (stable dark brown pigment); promote melanocyte division and melanin granule transport to keratinocytes, creating uniform long-lasting tan and mitigating direct UV-induced DNA damage.
- Central MC4 Receptor Modulation (Appetite, Metabolism, Libido)
- Hypothalamic MC4: Suppress hunger signaling, reduce cravings for high-calorie food and cut total calorie intake; boost systemic lipolysis efficiency;
- Spinal & peripheral reproductive MC4: Dilate pelvic blood vessels, elevate nitric oxide release to improve erectile function and sexual sensitivity.
- MC3 Receptor Anti-Inflammation, Antioxidation & NeuroprotectionInhibit systemic pro-inflammatory mediators TNF-α and IL-6, scavenge cutaneous and systemic free radicals, relieve photoinduced skin inflammation and chronic low-grade inflammation; protect neurons against oxidative apoptosis.
- MC5 Receptor Sebaceous Gland RegulationMildly modulate sebum secretion, balance skin oiliness and relieve inflammatory redness of oily skin.
Core Efficacy
1 Long-Lasting Even Tanning (Primary Core Benefit)
- Generate natural bronze/wheat skin tone without intense UV exposure, eliminating risks of sunburn, peeling, photoaging and skin cancer from over-sun exposure.
- Uniform pigment deposition without patchy or orange fake tan discoloration; tone remains stable and fades slowly and naturally after cessation instead of rapid fading.
- Boost natural skin UV defense: Melanin absorbs UV spectrum to reduce UV-triggered DNA damage, sun spots and red blood streaks.
- Fade post-inflammatory pigmentation and light acne marks: Stimulate even melanin distribution to relieve uneven skin tone and light scar discoloration.
2 Appetite Suppression & Auxiliary Fat Loss Metabolism
- Downregulate hypothalamic hunger signals, reduce cravings for sweets, fried food and carbohydrates, naturally lower daily calorie intake.
- Mild lipolysis boost with preferential visceral fat breakdown, assist relief of central obesity and insulin resistance.
- No lean muscle wasting; accelerates fat loss when stacked with calorie-controlled low-carb diet.
3 Improve Male Sexual Function & Libido
- Dilate pelvic microvessels and raise local nitric oxide levels to enhance erection hardness and endurance.
- Elevate sexual sensitivity, relieve low libido and slow arousal caused by chronic stress and aging.
4 Systemic Anti-Inflammation, Skin Repair & Antioxidation
- Suppress cutaneous pro-inflammatory mediators to relieve post-sun redness, sensitivity and inflammatory acne swelling.
- Scavenge skin free radicals, mitigate oxidative aging induced by UV and sleep deprivation and reduce fine line formation.
- Suppress systemic low-grade inflammation to relieve metabolic inflammation and mild inflammatory joint soreness.
