What is Metastin 10?

A reproductive neuropeptide that stimulates GnRH and gonadotropin release; studied for fertility and hypogonadism research.

This profile is educational. It organizes publicly discussed research context for Metastin 10 and related naming aliases — it is not a treatment guide.

Proposed mechanism

Activates KISS1R (GPR54) on GnRH neurons, triggering LH/FSH release and downstream sex steroid production.

Mechanism language on PepGuide describes how researchers discuss pathways. Proposed mechanisms can change as evidence evolves.

Current research notes

Human evidence grade: Moderate human evidence

Preclinical evidence grade: Strong human evidence

Kisspeptin-10 is the critical upstream regulator of puberty and reproduction. Human studies demonstrate robust LH pulses in healthy men and women. Researchers study it for hypogonadotropic hypogonadism, IVF triggers, and sexual function. Human evidence is moderate for physiological endpoints; therapeutic products limited.

Key uncertainties

  • Therapeutic product development
  • Chronic use effects

Research areas being studied

  • Hypogonadism
  • Fertility research
  • Puberty disorders
  • Reproductive endocrinology

Being studied for a topic is not the same as proven benefit in that topic. Prefer primary literature for study design, endpoints, and limitations.

Safety & side-effect notes

Reported or discussed adverse effects

  • Generally well tolerated in short studies
  • Mild nausea reported

Additional risks & considerations

  • Hormonal perturbation
  • Research-stage only for most uses
