Kisspeptin-10

Also known as: Metastin, KP-10

Kisspeptin-10 is a neuropeptide that regulates reproductive hormone secretion. It stimulates GnRH, leading to LH and FSH release, and may enhance libido and sexual function.

Beginner Basics

Plain-English guide to Kisspeptin-10

What it does

Kisspeptin-10 signals your brain to release hormones that control sexual function and testosterone production. Researchers study it because it may naturally boost libido and fertility markers.

Typical dose

1-2 micrograms daily or as needed, injected under the skin or sprayed in the nose. Start with the smallest dose since it's very potent.

When to inject

Morning or shortly before sexual activity, depending on your goals and how your body responds.

Storage

Keep the dry powder in the refrigerator. Once mixed with liquid, store it in the refrigerator and use it within the timeframe specified by your supplier.

First-timer tip

This peptide is extremely strong, so begin with 1 microgram and wait several days to see how you respond before increasing the dose.

Research Areas

Increases testosterone naturally
Enhances libido
Improves fertility markers
May increase LH and FSH
Supports reproductive health
Mood enhancement

Side Effects

Injection site reactions (redness, mild swelling, itching)
CommonMild

Usually resolves within 1-2 hours. Rotate injection sites to minimize. Apply ice if needed. Ensure proper site rotation and sterile technique.

Facial flushing or warmth
CommonMild

Occurs shortly after injection due to rapid hormone elevation. Typically self-resolving within 15-30 minutes. Not dangerous but may be noticeable.

Headache
UncommonMild

May occur in response to rapid hormonal changes. Usually mild and transient. Stay hydrated and consider timing injections to avoid peak activity periods if bothersome.

Nausea or mild gastrointestinal discomfort
UncommonMild

Rare but documented in clinical studies. Typically mild and self-resolving. Take with food if it occurs.

Acne or skin changes
UncommonMild

Secondary to increased testosterone or other sex hormones. Manage with standard skincare; usually mild if it occurs.

Mood changes or emotional sensitivity
UncommonMild

Possible due to hormonal fluctuations. Monitor mood and discontinue if significant emotional disturbance occurs.

Testicular or pelvic discomfort
RareMild

Reported in some users, possibly related to rapid hormone elevation. Usually resolves quickly. If persistent, discontinue and consult a healthcare provider.

Lipodystrophy (localized fat loss at injection sites)
UncommonModerate

Preventable through strict site rotation. Use a new site for each injection, maintaining at least 1 inch spacing and 7-day intervals between the same site.

Allergic reaction (rash, itching, swelling, difficulty breathing)
RareSerious

Seek immediate medical attention if any signs of anaphylaxis occur. Discontinue use immediately. Have an epinephrine auto-injector available if you have a history of peptide allergies.

Excessive hormone elevation or overstimulation
RareModerate

Kisspeptin-10 is extremely potent; overdose can cause exaggerated hormone spikes. Start with the lowest dose (50mcg) and titrate slowly. Monitor for signs of excessive stimulation (severe flushing, palpitations, extreme mood changes).

Reconstitution Guide

Do not use saline or bacteriostatic saline, use only bacteriostatic water for reconstitution

Do not shake the vial vigorously; gentle swirling prevents peptide degradation

Discard immediately if the solution appears cloudy, discolored, or contains visible particles

Use within 30 days of reconstitution when stored at 2-8°C

Do not freeze the reconstituted solution; freezing may denature the peptide

Half-lifeApproximately 54 minutes (in humans, subcutaneous administration)
SequenceMembers only

Kisspeptin-10 is a neuropeptide that acts as a potent stimulator of GnRH (gonadotropin-releasing hormone) secretion from the hypothalamus. This triggers the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the anterior pituitary, which regulate reproductive function and sex hormone production. By activating the KISS1R receptor on GnRH neurons, kisspeptin-10 essentially 'unlocks' the reproductive axis, making it a key regulator of puberty, fertility, and sexual function.
