Kisspeptin-10

Space-filling model of Kisspeptin-10

Kisspeptin-10 sits one rung above GnRH (gonadotropin-releasing hormone) in the reproductive chain: it acts on the neurons that release GnRH, and so sets the pulses driving luteinising hormone and follicle-stimulating hormone. A 2005 paper established that link directly, showing the effect through the GPR54 receptor and losing it in mice bred without that receptor. Imperial College London has since run a series of human studies with it, and the interest attached to it here is libido and raising those reproductive hormones. What is on file is graded observational rather than randomised, and there is no approved product. The anti-doping rule is unusually specific: kisspeptin is named for male athletes, prohibited at all times.

Half-life, storage & sport

Elimination half-life
not on file — no primary pharmacokinetic study found stating a human plasma half-life.
Storage
Lyophilised: Stable at room temperature ~3 weeks; store desiccated below -18C. Reconstituted: 4C for 2-7 days; below -18C with 0.1% HSA/BSA for long term; avoid freeze-thaw. — source. ProSpec technical datasheet. Supplier handling recommendation for research-grade lyophilate, not a per-compound stability study.
In sport (WADA 2026)
Prohibited, at all times, males only — named S2.2.1 (testosterone-stimulating peptides in males: kisspeptin and its agonist analogues). the list S2.2.1 is written for male athletes. For female athletes it is not captured by S2.2.1; kisspeptin-10 has no therapeutic approval, so S0 would then apply.

What is circulated not evidence 4

Claims passed around in community guides and vendor copy, recorded because they circulate — not because they are true. Each is shown with the page it was read from and what this record actually holds. Checked 2026-08-24.

  • unverified community data dose common agrees with the record

    A dose of about 1 mcg/kg (roughly 100 mcg) as a single injection is circulated as the point of highest LH response.

    Studies report that LH response is highest after administering a one-time dose of 1mcg/kg of body weight

    On the record The corpus dosing row holds 100-500 mcg three times weekly (raw: "100-500 mcg 3x/week"), verified: false. The record's regulatory row confirms verified human trials exist for kisspeptin-10, and 1 mcg/kg IV boluses are within the studied range — but the corpus does not hold a per-kg dose-response curve.

    Source 1

  • unverified community data timing common nothing on file either way

    It is circulated that daily dosing must be avoided because continuous kisspeptin exposure desensitises the receptor and suppresses the HPG axis.

    Researchers are advised against repeated daily dosing of the peptide.

    On the record The corpus records HPG-axis stimulation via GnRH neurons and pulsatile LH/FSH release as the mechanism, which is where the desensitisation logic comes from, but the record holds no study of subcutaneous daily community-style dosing or of a suppression threshold.

    Source 1

  • unverified community data benefit ubiquitous agrees with the record

    Increased LH, LH pulse frequency and testosterone in healthy males is circulated as the demonstrated benefit, extended by the community into a libido and PCT use.

    One such study found that injecting kisspeptin-10 into healthy males increased LH production, LH pulse frequency and size, and testosterone

    On the record The corpus benefits row holds libido support, LH/FSH elevation and testicular function, with verified human trial evidence recorded. The hormone-elevation part matches the record; the extension to post-cycle-therapy restart protocols has nothing on file. The record also notes WADA prohibition for male athletes (S2.2.1).

    Source 1

  • unverified community data timing occasional nothing on file either way

    Timing a dose 30-60 minutes before sexual activity for a libido effect is circulated as a protocol.

    45-60 minutes after administration

    On the record Nothing on file. The corpus holds no on-demand libido timing protocol; the study context is hormone measurement, not pre-activity dosing.

Identity

PubChem CID 25240297 computed 3D conformer Space-filling 3D model of Kisspeptin-10, carbon grey, nitrogen blue, oxygen red
Built from the SMILES on this record — the atoms and bonds are exact. The shape is one computed low-energy pose, not a measured structure: a flexible peptide in solution has no single conformation, and where the SMILES leaves a stereocentre undefined the pose commits to one arbitrarily. The skeletal formula below claims connectivity and nothing more, which is what we actually know.

Classified as

HPG Axispathway
The feedback structure is why a record here may report a change in LH or FSH rather than in testosterone, and why those readings can move in opposite directions on the same page.
Subcutaneousroute
This is the route the reconstitution arithmetic assumes. Mass divided by diluent volume gives concentration, dose divided by concentration gives volume, and volume in mL multiplied by 100 gives units on a U-100 barrel: 5 mg in 2 mL is 2.5 mg/mL, and 0.25 mg comes out at 0.1 mL, which is 10 units.
Intravenousroute
A large share of the pharmacokinetic numbers attached to peptide records, half-life in particular, come from intravenous studies and often from animals. Those numbers describe an intravenous curve and do not transfer unchanged to a depot under the skin.
