Short answer
What is Kisspeptin?
Kisspeptin-10 is the 10-amino-acid active fragment of kisspeptin, the product of the KISS1 gene. It activates the KISS1R (GPR54) receptor.
It also appears in the literature as Kisspeptin-10, kisspeptin-10 (human), metastin 45-54, YNWNSFGLRF-NH2.

| STRENGTH | FORM | PRICE | CERTIFICATE |
|---|---|---|---|
| 10mg | Lyophilised powder | A$85 | Pending |
What has research on Kisspeptin examined?
Kisspeptin-10 has been given to healthy men and women in controlled human physiology studies measuring LH, FSH and testosterone responses. Longer forms such as kisspeptin-54 have also been studied in human reproductive-endocrinology trials.
The table lists primary sources by year and model. Findings describe the study subjects, not this research vial.
What adverse events have studies of Kisspeptin reported?
None of the fetched human kisspeptin-10 abstracts reports adverse events; the studies found are small hormone-response studies in healthy volunteers. In dogs, 14 days of IV kisspeptin-10 produced no overt drug-related toxicity (PMID 34126799). A trial of intranasal kisspeptin-54, a different isoform, reported no side effects or adverse events (PMID 40215751).
These findings describe the people or animals in each study. The sources list gives every PubMed record.
How do you reconstitute and store Kisspeptin?
Store the sealed vial frozen (about -20 degrees Celsius), dry and away from light until it is reconstituted.
After reconstitution with a sterile solvent, keep the solution at 2 to 8 degrees Celsius and avoid repeated freezing and thawing. Record the solvent, volume and date on the vial label.
BAC Water is the usual laboratory solvent. Dilute acetic acid is an alternative for peptides that dissolve poorly in water. The reconstitution guide and storage guide cover laboratory handling.
| STATE | TEMPERATURE | NOTES |
|---|---|---|
| Sealed vial | -20 °C | Dry and dark. Keeps to the label date. |
| Reconstituted | 2 to 8 °C | Sterile technique. Avoid repeat freeze and thaw. |
| In transit | Cold pack | Refrigerate or freeze on arrival. |

Kisspeptin questions
What adverse events have studies of kisspeptin reported?
None of the fetched human kisspeptin-10 abstracts reports adverse events; the studies found are small hormone-response studies in healthy volunteers. In dogs, 14 days of IV kisspeptin-10 produced no overt drug-related toxicity (PMID 34126799). A trial of intranasal kisspeptin-54, a different isoform, reported no side effects or adverse events (PMID 40215751).
Is kisspeptin a peptide?
Yes. Kisspeptin is a peptide of 10 amino acids.
Is kisspeptin a prescription medicine in Australia?
Kisspeptin is not named in the Poisons Standard (June 2026 instrument). Peptides Collective sells it for laboratory research use only.
Is kisspeptin banned in sport?
WADA's 2026 Prohibited List prohibits Kisspeptin at all times in male athletes, under S2.2.1 (testosterone-stimulating peptides).
What is the CAS number for kisspeptin?
The CAS number for Kisspeptin is 374675-21-5. Its PubChem CID is 25240297.
How long does an unopened kisspeptin vial keep?
A sealed vial of lyophilised powder keeps to the date on its label when stored frozen, dry and dark. Once reconstituted, keep the solution at 2 to 8 degrees Celsius and record the date on the label.
Does every kisspeptin batch have a certificate?
Yes. Every Kisspeptin batch is tested by [lab] before it goes on sale, and the certificate is published under the batch number printed on the vial. The current batch certificate is [pending].
Where is kisspeptin shipped from?
Orders ship tracked from Western Australia. Orders placed before [cut-off] leave the same business day. Delivery estimates by state are on the shipping page.
What purity is the current kisspeptin batch?
The current Kisspeptin batch certificate is [pending]. When it is published, it reports purity by HPLC to three decimal places and confirms identity by mass spectrometry.
Which solvent reconstitutes kisspeptin?
BAC Water (sterile water with 0.9% benzyl alcohol) is the usual laboratory solvent. Dilute acetic acid is an alternative for peptides that dissolve poorly in water. Record the solvent, volume and resulting concentration on the vial label.
How much does kisspeptin cost in Australia?
Kisspeptin costs A$85 for 10mg at Peptides Collective, in Australian dollars. Each price is per vial of lyophilised powder.
Does kisspeptin ship with a cold pack?
[Cold-pack policy from Nico.] Lyophilised powder tolerates short transit at room temperature. Refrigerate or freeze the vial on arrival.
