Peptides studied in relation to melanocortin receptors – Melanotan I and PT-141. Price and batch analysis.
This category includes synthetic analogues of alpha-melanocyte-stimulating hormone (α-MSH), whose molecular structure has been modified for greater stability under laboratory conditions. These compounds are studied for their interaction with melanocortin receptors, which are involved in a range of physiological processes – from skin pigmentation to the neurohormonal pathways associated with sexual behavior. It is precisely this shared receptor mechanism that places Melanotan I and PT-141 in the same research group, despite the different focuses of the studies surrounding them.
Melanotan I is a linear analogue of α-MSH, which in the scientific literature is primarily associated with the MC1R receptor and its role in melanogenesis. Researchers use it in the context of studies on skin pigmentation mechanisms and the potential links between the melanocortin system and UV-induced cellular responses. The product is available in lyophilized form of 10mg, intended solely for in vitro or other laboratory use.
PT-141 is a synthetic peptide derived from Melanotan II, exhibiting affinity for MC4R receptors in the central nervous system. In the scientific community, it is the subject of research related to the neuroendocrine regulation of sexual function and the central mechanisms of libido. As with all products in our catalog, PT-141 is intended exclusively for research purposes in a controlled laboratory environment.
Every batch is analysed by the independent Czech laboratory Janoshik using HPLC and LC-MS. The certificate of analysis (COA) is published on each product page, so the purity and the test date are visible before you order.
Lyophilized peptides should be stored refrigerated at a temperature between 2°C and 8°C, away from direct light and moisture. After reconstitution (if applicable within a laboratory protocol), storage at lower temperatures and use within a short period is recommended, in accordance with the laboratory's internal protocols.
The products offered in this category are intended solely for laboratory and scientific research purposes. They are not pharmaceutical products, are not intended for consumption by humans or animals, and should not be used outside of a controlled research environment.
