Three peptides studied for arousal, desire and sexual-response research, in one stack. Melanotan 2, Kisspeptin and PT-141 each act on different pathways, bundled at 10% off.
Out of stock
This stack combines three peptides researchers use to study sexual response and desire. Melanotan 2 is explored for its effects on pigmentation and arousal pathways, Kisspeptin for its central role in reproductive hormone signalling, and PT-141 (Bremelanotide) for arousal and motivation pathways in the brain. Bundled together at 10% off the combined vial price. For research use only.
This product is intended as a research chemical only. Not for human use. Peptides will arrive in a lyophilized (powder) form for maximum stability.
This bundle contains:
Intended Use: For research purposes only. All peptides require reconstitution with Bacteriostatic Water (BAC Water), sold separately.
Storage: Store vials in a cool, dry place away from direct sunlight. Once reconstituted, keep refrigerated at 2–8°C.
Solubility: Reconstitute with Bacteriostatic Water for best results.
Shelf Life: Lyophilized form has a shelf life of up to 24 months when properly stored. Once reconstituted, refrigerate and use within 4–6 weeks.
Handling: Ensure proper sanitization techniques are used during handling and reconstitution.
Melanotan 2 (MT-II) is a synthetic cyclic heptapeptide analog of alpha-melanocyte stimulating hormone (alpha-MSH), developed at the University of Arizona. It is a non-selective agonist at melanocortin receptors MC1R, MC3R, MC4R and MC5R, with greater metabolic stability than native alpha-MSH. MC1R activation on epidermal melanocytes increases eumelanin synthesis, producing skin darkening, while central MC4R agonism mediates effects on sexual arousal and appetite that have been observed in human and animal studies. MT-II is the parent molecule that led to the development of bremelanotide, a MC4R focused analog.
Kisspeptin is a family of peptides encoded by the KISS1 gene. The parent 54 amino acid form (kisspeptin-54, also called metastin) can be cleaved to shorter active fragments including kisspeptin-10, which retain affinity for the G protein coupled receptor KISS1R (GPR54). Hypothalamic kisspeptin neurons in the arcuate and AVPV nuclei project onto GnRH neurons, and KISS1R activation drives pulsatile GnRH release, which in turn stimulates pituitary LH and FSH secretion and downstream gonadal steroidogenesis. Loss of function mutations in KISS1R cause normosmic hypogonadotropic hypogonadism in humans, establishing the pathway as essential for puberty and reproduction.
Bremelanotide (PT-141) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH), with the sequence Ac-Nle-cyclo(Asp-His-D-Phe-Arg-Trp-Lys)-OH. It acts as a non-selective agonist at melanocortin receptors, with functional activity preferentially at MC4R and MC3R in central nervous system pathways that regulate sexual desire and arousal. Unlike PDE5 inhibitors, it does not act on the vascular nitric oxide pathway. It was approved by the FDA in 2019 (trade name Vyleesi) for premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD).

FAQ:
All Ai-Peptides products are manufactured in the USA under strict quality control. Each peptide is analyzed using HPLC and Mass Spectrometry to confirm identity and purity, typically ≥99%. Every batch comes with a Certificate of Analysis (COA) you can view to verify authenticity and research-grade quality.
Our peptides are shipped lyophilized (powder form) for maximum stability. Store them in a cool, dry place until use. For long-term preservation, keep them refrigerated or frozen. Once reconstituted with a suitable research-grade solvent, keep the solution cold and protected from light to maintain integrity.
All products on our website can be purchased in any quantity available, from a single vial to larger amounts, simply by adjusting the quantity in your cart. We do not currently offer special wholesale pricing or custom bulk arrangements.
