Om MT-2 (Melanotan 2 Acetate)
Melanotan II (MT-2) is a synthetic cyclic analogue of alpha-MSH (alpha-melanocyte-stimulating hormone), a peptide derived from POMC (proopiomelanocortin). It is a potent, non-selective agonist at melanocortin receptors (MC1R through MC5R), with particularly strong activity at MC1R and MC4R. This broad agonism is studied in research models in connection with both its well-characterised activity on skin pigmentation (via MC1R) and its research history around sexual-arousal pharmacology and appetite modulation (via MC4R).
The pharmacology is worth understanding in some detail. MC1R is expressed on melanocytes and regulates melanin production — in research models MT-2 is studied for activation of eumelanin synthesis, associated with darker skin pigmentation without UV exposure. MC4R is expressed in the hypothalamus and plays roles in melanocortin signalling and sexual function — in research models its activation is studied for satiety signalling and, notably, pro-erectile effects in male rodent models. MC3R has roles in energy homeostasis. MT-2 activates all of these nonselectively, which produces the compound’s range of effects in research models and also complicates research interpretation where receptor-specific effects need to be isolated.
MT-2 was developed at the University of Arizona from research aimed at characterizing a compound that would drive melanin synthesis in model systems and, in turn, was studied in the context of UV-related skin biology. The broader melanocortin agonism effects became apparent during development. It has been investigated in preclinical research on sexual-arousal pharmacology, and a related derivative (bremelanotide/PT-141) shares the same MC4R-mediated mechanism.

What melanocortin receptors does MT-2 activate?
MT-2 is a non-selective melanocortin receptor agonist with activity at MC1R, MC3R, MC4R, and MC5R. MC1R mediates skin and hair pigmentation (studied in research models for activation of eumelanin synthesis in melanocytes). MC3R and MC4R are expressed in the hypothalamus and have roles in energy homeostasis, appetite, and sexual function. In research models, MC4R activation is studied for MT-2’s pro-erectile effects in rodent models and its satiety effects. MC5R has roles in exocrine gland function. MT-2’s lack of receptor selectivity is a key consideration for research design when receptor-specific effects need to be distinguished.
How does MT-2 relate to PT-141 (bremelanotide)?
PT-141 (bremelanotide) is a metabolite of MT-2 that differs only at the C-terminus (a free acid instead of an amide); both peptides are cyclic. In research, it is the compound associated with the MC4R-mediated sexual-arousal pharmacology rather than the tanning or other melanocortin effects. MT-2 is the research precursor that established the MC4R-mediated arousal pharmacology that PT-141 was developed from.
What was the original research goal for MT-2?
MT-2 was developed at the University of Arizona in the 1980s-90s with the goal of characterizing a compound that would produce melanin synthesis without UV exposure in model systems, studied in the context of UV-related skin biology. The pro-pigmentation activity via MC1R was the primary target. The broader melanocortin receptor agonism — including the MC4R-mediated effects on sexual arousal and appetite in animal models — was discovered during development and shifted the research direction significantly.

Peptider i lyofiliserad (frystorkad) form skickas i förseglade glasvialer med standardleveransmetoder och kräver ingen kylning under transporten. Lyofiliserade peptider är mycket stabila vid omgivningstemperatur under hela den normala frakttiden (typiska transporttider visas i kassan). När du tagit emot produkten ska du snabbt flytta den till kyld förvaring (2–8°C).
Vanliga frågor
Forskningspeptider levereras i lyofiliserad (frystorkad) form. Mängden material är vanligtvis bara några milligram — och framträder som en mycket tunn film eller en liten pellet i botten av vialen, ofta nästan osynlig. Detta är helt normalt.
Till skillnad från vissa leverantörer som tillsätter fyllnadsmedel (som mannitol) tillhandahåller CertaPeptides ren peptid utan onödiga tillsatser.
