Low libido
A plain-language symptom. Compare The Peptide maps it to these engine terms: melanocortin pathway, HPG axis support, arousal modulation, GnRH axis signal. The mapping is this site's, printed here so you can judge it.
Matched peptides
Highest match first. The score is the share of this entry's targets the peptide carries; it is a match score, not a verdict.
| Peptide | How it works | Why it matches | |
|---|---|---|---|
| Bremelanotide Hormonal & reproductive | Bremelanotide is a cyclic heptapeptide melanocortin receptor agonist with high affinity for MC4R and MC1R. Unlike other melanocortins, it acts centrally in the ... | melanocortin pathway, arousal modulation | Compare & quote |
| Gonadorelin Hormonal & reproductive | Hypothalamic releasing hormone that stimulates LH and FSH release from anterior pituitary. Pulsatile administration maintains receptor sensitivity and supports ... | HPG axis support, GnRH axis signal | Compare & quote |
| Kisspeptin Hormonal & reproductive | GnRH release; LH/FSH stimulation; Reproductive axis activation | HPG axis support, GnRH axis signal | Compare & quote |
| Kisspeptin-10 Hormonal & reproductive | Binds to GPR54/KISS1R receptor in hypothalamus, stimulating pulsatile release of gonadotropin-releasing hormone (GnRH), which triggers LH and FSH secretion from... | HPG axis support, GnRH axis signal | Compare & quote |
| Melanotan II GLP-1 & metabolic | MC1R - melanogenesis; MC4R - sexual arousal; MC3R - appetite suppression | melanocortin pathway, arousal modulation | Compare & quote |
| Melanotan I GLP-1 & metabolic | Melanocortin receptor agonist; binds MC1R on melanocytes, activating adenylyl cyclase → cAMP → PKA → CREB → MITF → increased tyrosinase expression → eumelanin s... | melanocortin pathway | Compare & quote |
| Oxytocin Nootropic & neuro | Nonapeptide neurohormone that binds oxytocin receptors (OXTR), activating Gq/11 signaling. In the CNS, modulates social behavior, trust, and bonding. Peripheral... | arousal modulation | Compare & quote |
| VIP Other peptides | 28-amino acid neuropeptide that binds to VPAC1 and VPAC2 G-protein coupled receptors, activating adenylyl cyclase and increasing cAMP. Causes potent vasodilatio... | arousal modulation | Compare & quote |
What the quotation does
For the peptides you pick it lists the products vendors in your country offer, each clickable, and ranks them three ways: best price (product price per mg), best value (price per mg after the water, syringes or needles the format forces), and best overall (value, days usable after opening, handling and quantity, weighted in the open). Every number's working is printed under it.
