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. Purity and identity are confirmed per lot before dispatch.

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, and the stated activity for your lot appears on its certificate of analysis alongside the identity confirmation.
- Does every endocrine research reference come with a certificate?
- Yes. Each vial ships with a certificate of analysis issued for its own lot number, showing reverse-phase HPLC purity and LC-MS identity confirmation from an independent partner laboratory.
- 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.
