Gonadotropin & endocrine peptides

This range holds the references used in reproductive and endocrine signalling research: kisspeptin, the KISS1 gene product acting at GPR54; gonadorelin, the synthetic decapeptide identical to endogenous GnRH; and gonadotropin preparations such as HCG and HMG, together with oxytocin.

These compounds are standard comparators in receptor-binding and pituitary-response assays, where an accurately quantified reference matters more than anything else. Every product has undergone independent purity and identity testing.

Common questions

Gonadotropin & Endocrine, answered

How are IU-based references such as HCG and HMG quantified?
Gonadotropin preparations are quantified in international units rather than by mass. Representative product documentation shows the stated activity and identity-testing information where available.
Has every endocrine research product been independently tested?
Yes. Every product has undergone independent HPLC and LC-MS testing, and certificates of analysis are available to view on the relevant product pages.
How quickly are orders dispatched?
Orders that clear payment before the daily cut-off are typically dispatched within 24 hours from the UK, with tracked delivery to the United Kingdom and the European Economic Area countries we serve.
Can these compounds be used on humans or animals?
No. Everything in this range is an unlicensed reference standard supplied for in-vitro laboratory research by qualified professionals only. Nothing we sell is a medicine, supplement or cosmetic.
