What are hormone peptides?
Kisspeptin-10 is the active fragment of kisspeptin, the signal that tells the hypothalamus to release GnRH, which sits at the top of the LH and FSH chain.
HCG, human chorionic gonadotropin, is a large glycoprotein hormone that acts on the same receptor as LH. Enclomiphene is the trans-isomer of clomiphene, a small molecule that blocks estrogen feedback at the pituitary.
The research behind this range is indexed on PubMed, the free database of the U.S. National Library of Medicine. Start with this PubMed search.

How to choose hormone peptides

HCG is measured in international units, not milligrams. Its product page has a mixing chart in IU.

Storage and handling

Write the arrival date and, later, the mixing date on every vial or bottle. Those two dates answer most questions later.
