Sexual health
Kisspeptin-10
KP-10 · 10-aa · reproductive hormone
A genuine, actively-researched reproductive-hormone peptide — real human trial data exists (including from UK academic research), but it's not an approved treatment.

What it is
Kisspeptin sits upstream of the reproductive hormone system, triggering release of GnRH and downstream sex hormones. It's one of the better-studied compounds in this library in humans specifically — UK academic research (including work at Imperial College London) has run real randomised trials on kisspeptin for low sexual desire and as part of fertility-treatment protocols.
Despite this genuine research pedigree, it is not an approved treatment for libido or fertility — the trials are still investigational, and what's sold to consumers is an unregulated research chemical, not the trial-grade product.
The science, graded
What’s claimed — and how strong the evidence behind each claim actually is.
“Increases sexual desire in people with low libido”
Supported by genuine UK academic randomised trials — one of the better human-evidence cases in this library.
Claim-level citation mapping is in progress.
“Plays a role in fertility-treatment hormone triggering”
Actively studied as part of IVF-adjacent protocols in research settings.
Claim-level citation mapping is in progress.
“An approved, ready-to-use libido treatment”
It remains investigational — not an approved treatment despite the promising trial data.
Claim-level citation mapping is in progress.

What the community says
Discussed with more scientific credibility than most sexual-health peptides, partly because its trial history is genuinely traceable to named academic institutions rather than only community anecdote.
