Frequently Asked Questions

What links the compounds in this category?

They are grouped by the signaling systems studied in the source literature rather than by structure. PT-141 is a melanocortin receptor ligand, kisspeptin-10 is studied in the context of GnRH regulation, and HCG appears as a reference gonadotropin in reproductive-endocrinology work.

Why is HCG specified in international units?

HCG is a glycoprotein, and potency for glycoproteins is established by bioassay rather than by mass or by HPLC purity alone. That is why the listing reads 5000 IU instead of a milligram figure.

What is kisspeptin-10?

Kisspeptin-10 is the ten-amino-acid C-terminal fragment of the kisspeptin family, studied for its role in the signaling cascade upstream of GnRH release in animal and cell models.

How are melanocortin and gonadotropin materials stored?

Lyophilized peptides in this category are held at 2 to 8 C, or frozen for long-term storage. HCG in particular is kept refrigerated and protected from light, and reconstituted material is treated as short-dated. For laboratory research use only.
