Kisspeptin and HCG both appear in reproductive-endocrinology research, but they act at opposite ends of the hypothalamic-pituitary-gonadal axis: upstream signaling versus a downstream gonadal receptor.
At a glance
| Property | Kisspeptin | HCG |
|---|---|---|
| Class | Synthetic peptide (Kisspeptin-10) | Glycoprotein hormone |
| Primary research target | KISS1R (upstream of GnRH) | LH/CG receptor (gonadal) |
| Research domain | HPG-axis upstream signaling | Gonadal steroidogenesis |
| Structure | Decapeptide | Heterodimeric glycoprotein |
| Format | Lyophilized powder | Lyophilized powder |
Kisspeptin in research
Kisspeptin is studied as a KISS1R agonist acting upstream of GnRH in hypothalamic-pituitary-gonadal-axis research models. See the full Kisspeptin research profile.
HCG in research
HCG is a glycoprotein hormone studied for its agonist interaction at the LH/CG receptor and downstream gonadal-signaling pathways. See the full HCG research profile.
Key differences
- Kisspeptin acts upstream at KISS1R to drive GnRH research; HCG acts downstream at the gonadal LH/CG receptor.
- Kisspeptin is a small decapeptide; HCG is a heterodimeric glycoprotein hormone.
- Both are supplied as lyophilized research materials.
Selecting for a research model
Researchers select between Kisspeptin and HCG based on whether upstream hypothalamic or downstream gonadal signaling is under study. These distinctions are described strictly in the context of research models and are not statements of efficacy, safety, or suitability for any use.
Both Kisspeptin and HCG ship from Vantage Aminos with a batch-specific Certificate of Analysis (HPLC purity and mass-spectrometry identity), U.S. synthesized for research use.
