Melanotan-II and PT-141 both act on melanocortin receptors, while Kisspeptin-10 acts upstream in the reproductive axis these receptors intersect with, which is why the three are studied together in melanocortin and reproductive-signaling research rather than as isolated compounds.

Melanocortin & Reproductive combines Melanotan-II 10mg, PT-141 10mg, and Kisspeptin-10 10mg, pairing two melanocortin receptor agonists with different selectivity profiles alongside a peptide studied upstream in the reproductive axis they intersect with.
Melanotan-II is studied as a non-selective melanocortin receptor agonist. PT-141 is studied with a narrower CNS-mediated research focus, and Kisspeptin-10 is studied for KISS1 receptor activation upstream of GnRH secretion.
All three vials ship individually labeled and independently HPLC-verified before batch release. This product is intended strictly for laboratory research use only and is not approved for human consumption.
Melanotan-II and PT-141 both act on melanocortin receptors, while Kisspeptin-10 acts upstream in the reproductive axis these receptors intersect with, which is why the three are studied together in melanocortin and reproductive-signaling research rather than as isolated compounds. This is the logic behind the Melanocortin & Reproductive kit.
Melanocortin receptor biology and reproductive-axis signaling overlap more than researchers new to the category might expect, several melanocortin receptor subtypes are studied in connection with both pigmentation and reproductive-behavior research. This kit reflects that overlap: two melanocortin receptor agonists with different selectivity profiles, plus Kisspeptin-10, which sits upstream in the reproductive-axis pathway both agonists intersect with.
| Vial | Peptide | Strength | Research Focus |
|---|---|---|---|
| Vial 1 | Melanotan-II | 10mg | Non-selective melanocortin receptor agonism in pigmentation and appetite-related research. |
| Vial 2 | PT-141 | 10mg | Melanocortin receptor agonism studied for CNS-mediated signaling research. |
| Vial 3 | Kisspeptin-10 | 10mg | KISS1 receptor activation, studied upstream of GnRH secretion in HPG-axis research. |
Melanotan-II is a non-selective synthetic melanocortin receptor agonist, studied for pigmentation and appetite-related melanocortin research, engaging multiple melanocortin receptor subtypes rather than one specifically. Its non-selectivity is itself a research variable, since it allows researchers to observe effects across the full range of melanocortin receptor subtypes rather than isolating one.
PT-141 (Bremelanotide) is a melanocortin receptor agonist related to Melanotan-II, but studied specifically for central nervous system-mediated research relevant to melanocortin signaling, a narrower research focus than Melanotan-II's broader receptor engagement. Comparing the two compounds side by side is a common research design in studies examining how melanocortin receptor selectivity affects downstream signaling outcomes.
Kisspeptin-10 is a decapeptide fragment of the kisspeptin family, studied for KISS1 receptor activation, positioned upstream of GnRH secretion in the hypothalamic-pituitary-gonadal axis, the reproductive-signaling system that melanocortin receptor research frequently intersects with. Its inclusion here reflects the documented overlap between melanocortin signaling and reproductive-axis regulation, rather than an unrelated addition to the other two compounds.
Including both Melanotan-II and PT-141 in the same kit gives researchers a built-in comparative structure: the same broad melanocortin research question examined through a non-selective agonist and a narrower, CNS-focused one. This design mirrors how researchers elsewhere on the site pair a broad-spectrum secretagogue like GHRP-2 with a more selective one like Ipamorelin, applying the same selectivity-comparison logic to melanocortin receptor research instead of the growth hormone axis.

Each of the three vials ships individually labeled with compound name, strength, and batch lot number, none are pre-mixed. Every vial is independently verified through HPLC before batch release, with Certificates of Analysis available per component on request, the same documentation provided when any of the three peptides is purchased individually outside of this bundle.
Every vial in this kit, whether purchased here or as part of another bundle on the site, is manufactured and tested against the same research-grade standard.
