Evidence brief
Kisspeptin-10
Written and source-checked by Anthony Treviso, founder of The Peptide Field.
Direct answer
Kisspeptin-10 is a 10-amino-acid piece of a body signal. Researchers have studied its effects on reproductive hormones. It is not an FDA-approved treatment.
A research peptide that changed reproductive hormones for short periods in small human studies. This does not prove fertility, testosterone, or other treatment benefits.
- How strong is the evidence?
- Emerging
Some studies in people exist. Important questions remain about benefit, safety, who it helps, or how long the effects last. This is not an approval or recommendation. - What evidence exists?
- Human pharmacology only
Studies in people measured how the substance changed the body. This did not establish a health benefit on its own. - Sports rules
- Prohibited
The checked rules list this substance or group as prohibited under the stated conditions. Check the current rules for your sport.

01 · Evidence profile
Four questions about the evidence
Small studies measured short-term hormone changes. They did not show better fertility, pregnancy, or lasting treatment results.
Studies in people measured how Kisspeptin-10 changed reproductive hormones during short research periods.
The studies were small and brief. They cannot show uncommon harms or long-term safety.
Study material was controlled. The identity and quality of products sold outside those studies are not established.
02 · Identity
What it is
Kisspeptin-10 is a short piece of a natural body signal called kisspeptin. This signal helps control hormones involved in puberty and reproduction. Kisspeptin-10 has 10 amino acids, the small building blocks that make peptides. It is not the same molecule as Kisspeptin-54. Results for Kisspeptin-54 do not automatically apply to Kisspeptin-10.
Scientific group: Reproductive signaling peptide. This group name describes the type of molecule or body signal. It does not prove a benefit, safety, or approval.
03 · Exact product
The molecule is not the finished product.
Formulation: The finished product's ingredients and physical form. Route: How the product enters the body. Indication: The approved or studied use and group of people for a product.
None identified in the United States.

04 · Research results
What the research shows
Small human studies measured short-term hormone changes. A 2026 study included 15 healthy men. It found changes in luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone during controlled research. LH and FSH are body signals involved in reproduction. The study measured hormone activity, not a health benefit.
These studies do not show that Kisspeptin-10 improves fertility, causes pregnancy, treats low testosterone, increases muscle, lowers body fat, or improves libido. They do not establish long-term safety. Results from animals, Kisspeptin-54, or other kisspeptin drugs cannot fill these gaps.
Exact product
Kisspeptin-10 has an FDA identity record, but that record is not an approval. FDA lists the substance in Category 2 for compounding. This category covers substances that may present significant safety risks. A product sold under the same name is not proven to match the material used in a study.
05 · Claim check
Claims I checked
4 claims checked for this brief.
“Kisspeptin-10 raises reproductive hormones in humans.”
Small studies measured increases in reproductive hormones. Some also found short-term testosterone changes. These measurements do not prove a treatment benefit.
- Evidence used
- Human pharmacology. This answer uses a study of how the substance enters or changes the body in people. This alone does not show a health benefit.
- Limits of this answer
- Small, short studies in healthy men. The studies measured hormones, not fertility or treatment success. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
“Kisspeptin-10 treats infertility, low testosterone, or hypogonadism.”
Human studies mainly measured short-term hormone responses. FDA found too little evidence to judge whether Kisspeptin-10 treats secondary hypogonadism.
- Evidence used
- No reliable human outcome evidence. No reliable study in people shows the health outcome in this statement.
- Limits of this answer
- Treatment outcomes for infertility, low testosterone, or hypogonadism. Hypogonadism means that the sex glands do not make enough hormones. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
“Kisspeptin-10 is FDA-approved.”
No FDA-approved product was identified. An FDA identity record does not mean approval. FDA also lists Kisspeptin-10 among substances that may present significant safety risks in compounding.
- Evidence used
- Regulatory or product record. This answer uses an official regulator record or a specific product label.
- Limits of this answer
- United States status as reviewed August 30, 2026. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
