Dosing & Reconstitution Guide
A single practical dilution with accurate once-daily dosing, step by step
Standard / Gradual Approach (3 mL = ~3.33 mg/mL)
Reconstitute: Add 3.0 mL bacteriostatic water to one 10 mg vial → final concentration ~3.33 mg/mL (3,333 mcg/mL).
Typical daily range: 100–200 mcg once daily, raised gradually over an 8–12 week course.
Easy measuring: At ~3.33 mg/mL, 1 unit ≈ 33.3 mcg on a U-100 syringe. So 100 mcg = 3 units (0.03 mL) and 200 mcg = 6 units (0.06 mL); for these small volumes a 30- or 50-unit syringe improves readability.
Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the mixed solution.

Fertility & IVF research
Explored in clinical research on egg-maturation triggers and hypothalamic amenorrhea — investigational, human trials only.
Libido & sexual function
Studied for effects on sexual and emotional brain processing in early human research — investigational, not approved.
Testosterone & LH support
Researched as a stimulus for luteinizing hormone and testosterone secretion in preliminary human studies — investigational.
Evidence ranges from early laboratory work to clinical trials depending on the use — the sections below cover the actual data and sources.
Quickstart Highlights
Kisspeptin (also called metastin; the KISS1 gene product, available as kisspeptin-10 or kisspeptin-54) is a naturally occurring neuropeptide that stimulates hypothalamic GnRH neurons to drive release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH)[1][5]. This educational page outlines a once-daily subcutaneous approach with a dilution chosen so doses land on easy-to-read insulin-syringe marks. Kisspeptin is an investigational research compound — it is not approved by the FDA, EMA or any regulator for human use, and human use is research-only — presented for research and educational use only.
Add 3.0 mL bacteriostatic water to one 10 mg vial → ~3.33 mg/mL (3,333 mcg/mL), a practical dilution for accurate low-volume dosing.
100–200 mcg once daily, titrated upward gradually across an 8–12 week course (about ~0.7–1.4 mg per week).
At ~3.33 mg/mL, 1 unit ≈ 33.3 mcg; 100 mcg ≈ 3 units and 200 mcg ≈ 6 units on a U-100 syringe.
Lyophilized: store at −20 °C (−4 °F); once reconstituted, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the solution.
Important: Start with the Prep & Injection Guide — it covers the preparation and safety basics every protocol on this site assumes.
Frequency: one subcutaneous injection each day, following a conservative titration to assess individual response[4][5]. These figures come from reference protocols, not from approved human dosing.
Reconstitution Steps
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
Release it slowly down the vial’s inner wall to limit foaming.
Swirl or roll gently until fully dissolved — don’t shake.
Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.
At ~3.33 mg/mL each dose reads at 3–6 units; for these small volumes a 30- or 50-unit insulin syringe makes the markings easier to read. Avoid freezing the reconstituted solution, since freeze–thaw can denature the peptide.

Protocol Overview
A concise summary of the once-daily regimen, drawn from commonly cited reference protocols.
- ▪Goal: Stimulate the body’s own GnRH neurons to support physiological LH/FSH and downstream sex-hormone signaling — studied in reproductive and HPG-axis research, not established for human therapeutic use[1][7].
- ▪Schedule: Daily subcutaneous injections for 8–12 weeks, optionally extended to ~16 weeks for longer research goals.
- ▪Dose Range: 100–200 mcg per day with gradual titration.
- ▪Reconstitution: 3.0 mL bacteriostatic water per 10 mg vial gives ~3.33 mg/mL for accurate low-volume measurements.
- ▪Storage: Keep the dry vial frozen at −20 °C (−4 °F); once mixed, refrigerate at 2–8 °C and do not freeze the solution.
Dosing Protocol
A suggested daily titration approach based on common reference doses.
- ▪Start: Begin at 100 mcg once daily for 1–2 weeks to assess sensitivity.
- ▪Titrate: Increase toward 200 mcg once daily if tolerated and necessary.
- ▪Target: A daily dose of about 200 mcg by weeks 5–12.
- ▪Cycle Length: Typically 8–12 weeks; avoid prolonged continuous use to limit tachyphylaxis[6].
- ▪Timing: Inject at a consistent time each day and rotate injection sites systematically.
Storage Instructions
Correct storage is what preserves the peptide’s stability and activity.
- ▪Lyophilized: Hold the dry vial at −20 °C (−4 °F) in dry, dark conditions and limit moisture exposure[7].
- ▪Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 28 days; do not freeze the mixed solution, as freezing can denature peptides[8].
- ▪Handling: Let frozen vials warm to room temperature before opening so condensation won’t form, and keep the solution clear of heat and direct light.
- ▪Freeze–thaw: Avoid repeated freeze–thaw cycles of the reconstituted solution.
Important Notes
Practical points that keep daily administration safe and consistent.
- ▪Sterile technique: Use a fresh sterile U-100 insulin syringe each time and drop it straight into a puncture-proof sharps container afterward.
- ▪Site rotation: Move between abdomen, thighs and upper arms to reduce local irritation and lipohypertrophy[9].
- ▪Slow injection: Push the plunger slowly and pause a few seconds before withdrawing the needle to prevent backflow.
- ▪Recordkeeping: Log the daily dose, injection site and any observations to keep the protocol consistent.
- ▪Regulatory note: Kisspeptin is an investigational research compound and is not approved by the FDA, EMA or any regulator for human use[10].
How This Works
Kisspeptin (the KISS1 gene product) is an upstream trigger for the reproductive hormone cascade. On subcutaneous administration it binds the kisspeptin receptor (GPR54 / KISS1R) on GnRH neurons in the hypothalamus, prompting pulsatile release of GnRH[1][7].
That GnRH release in turn stimulates the anterior pituitary to secrete LH and FSH, which act on the gonads to support sex-steroid production and gametogenesis[8]. Because the effect is GnRH-dependent, blocking GnRH abolishes kisspeptin’s LH/FSH response — confirming it works by engaging the body’s own hypothalamic machinery[9].
Compared with direct GnRH or hCG, kisspeptin produces a more physiologic, self-limiting pattern of hormone release, which is why it has been studied as a research tool in reproductive endocrinology[10].
Important caveat: kisspeptin’s reproductive effects are documented mainly in early-phase and mechanistic research. It has not been approved by any regulator for human treatment, and any reproductive, fertility or hormone-related uses should be read as research hypotheses rather than established benefits.
Kisspeptin is not an approved medicine. It is an investigational research compound presented here for research and educational purposes only.
Lifestyle Factors
Habits that may support healthy hormone signaling alongside the protocol.
- ▪Nutrition: Maintain adequate nutrition and a healthy body weight to support endogenous hormone production.
- ▪Activity & rest: Balance regular activity with recovery; chronic energy deficit and overtraining can suppress the HPG axis.
- ▪Sleep: Aim for 7–9 hours, since sleep strongly influences reproductive hormone rhythms.
- ▪Stress: Manage stress with evidence-based practices, since it can disrupt hypothalamic GnRH signaling.
Potential Benefits & Side Effects
What reproductive-endocrinology research describes; human evidence is early-phase and individual results vary.
Potential Benefits
- ▪Sex-hormone stimulation (research): Raises endogenous LH/FSH and downstream sex steroids by engaging the body’s own GnRH pulse generator, without bypassing the HPG axis[8].
- ▪Reproductive research (early-phase): Studied in functional hypothalamic amenorrhea and as an IVF ovulation trigger, where it can induce an LH surge with potentially lower ovarian-hyperstimulation risk than hCG[11].
- ▪Tolerability (research): Generally well tolerated in studies, with occasional mild injection-site reactions.
- ▪Note on humans: Kisspeptin remains investigational — it is not approved for human treatment, and large-scale efficacy is not established[13].
Common Side Effects
- ▪Injection-site reactions: Mild redness, tenderness or soreness can occur; rotating sites helps.
- ▪Unknown long-term profile: Human safety data is limited, so caution and monitoring are advised.
- ▪Hormonal effects: By design it perturbs reproductive hormone levels; effects on the HPG axis should be monitored in any research setting.
Injection Technique
General subcutaneous technique, following established clinical best-practice guidance[14][15].
Pre-Injection Preparation
- ▪Wash your hands well with soap and water.
- ▪Wipe the vial stopper with an alcohol swab and let it air-dry.
- ▪Choose a site (abdomen, thigh, or upper arm) and clean it with a fresh alcohol swab, letting it dry fully[15].
- ▪Draw the intended dose, then check for air bubbles and push any out.
Injection Procedure
- ▪Pinch a skinfold at the chosen site between thumb and forefinger.
- ▪Insert the needle into the pinch at a 45–90-degree angle (use 45 degrees if the fat layer is thin)[14].
- ▪Skip aspiration for subcutaneous shots — it isn’t needed[14].
- ▪Press the plunger slowly and steadily until it’s fully down.
- ▪Wait 5–10 seconds, then pull the needle straight out to prevent leakage.
Post-Injection Care
- ▪Drop the used syringe straight into a puncture-proof sharps container — never recap a needle.
- ▪Return the reconstituted vial to the fridge right away.
- ▪Rotate the injection site each day to prevent irritation and lipohypertrophy[9].
- ▪Watch the site for excess redness, swelling, or signs of infection.

Kisspeptin — frequently asked questions
How do I reconstitute a 10 mg vial of Kisspeptin?
Wipe the stopper with an alcohol swab, then inject your bacteriostatic water slowly down the inside wall of the vial. Let it sit and gently swirl until dissolved — never shake. Store the mixed vial in the refrigerator and draw doses with an insulin syringe. Use the calculator above to turn any dose into syringe units.
How much bacteriostatic water should I add to Kisspeptin?
There is no single correct amount — more water simply spreads the same 10 mg of peptide across a larger volume, which makes small doses easier to measure accurately. 1 to 3 mL per vial is typical. Enter your chosen volume in the calculator above to see the resulting concentration and syringe units.
What do the "units" on an insulin syringe mean?
On a U-100 insulin syringe, 100 units equal 1 mL, so 1 unit equals 0.01 mL. The calculator above converts your draw volume into these units automatically so you can measure without doing the math by hand.
How should I store Kisspeptin after mixing?
Keep the reconstituted vial refrigerated at roughly 2 to 8 degrees Celsius, away from light, and avoid freezing it. Reconstituted research peptides are generally used within a few weeks. Always follow the specific guidance supplied with your product.
How many doses does a 10 mg vial of Kisspeptin provide?
Divide the vial strength of 10 mg by the amount you use per injection. The calculator above reports this as "doses per vial" the moment you enter a dose.
Is Kisspeptin approved for human use?
No. Kisspeptin is sold strictly for laboratory and research purposes and is not approved by the FDA or other regulators for human use. Everything on this page is research information, not medical advice — consult a licensed healthcare professional before any use.
