Kisspeptin (10 mg Vial) Dosage Protocol

Quickstart Highlights

Kisspeptin (also known as metastin) is a naturally occurring neuroendocrine peptide that plays a pivotal role in human reproduction by stimulating gonadotropin-releasing hormone (GnRH) secretion^[1]. This small peptide binds to the GPR54 receptor in the hypothalamus, triggering pulsatile GnRH release and downstream secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH)^[2]. Originally identified as a metastasis-suppressor gene product, kisspeptin has become a major focus in reproductive endocrinology^[3]. This educational protocol presents a once-daily subcutaneous approach for research use.

Reconstitute: Add 3.0 mL bacteriostatic water → ~3.33 mg/mL concentration.

Typical daily range: 100–200 mcg once daily (gradual titration).

Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U‑100 insulin syringe.

Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.

Dosing & Reconstitution Guide

Educational guide for reconstitution and daily dosing

Standard / Gradual Approach (3 mL = ~3.33 mg/mL)

Week	Daily Dose (mcg)	Units (per injection) (mL)
Weeks 1–2	100 mcg	3 units (0.03 mL)
Weeks 3–8 (or 3–12)	200 mcg	6 units (0.06 mL)

Frequency: Inject once daily subcutaneously. This schedule follows a conservative titration to assess individual response^[4]^[5]. For ≤10-unit (≤0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.

Reconstitution Steps

Draw 3.0 mL bacteriostatic water with a sterile syringe.

Inject slowly down the vial wall; avoid foaming.

Gently swirl/roll until dissolved (do not shake).

Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed

Plan based on an 8–16 week daily protocol with gradual titration.

Peptide Vials (Kisspeptin, 10 mg each):

8 weeks ≈ 1 vial
12 weeks ≈ 2 vials
16 weeks ≈ 3 vials

Insulin Syringes (U‑100):

Per week: 7 syringes (1/day)
8 weeks: 56 syringes
12 weeks: 84 syringes
16 weeks: 112 syringes

Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.

8 weeks (1 vial): 3 mL → 1 × 10 mL bottle
12 weeks (2 vials): 6 mL → 1 × 10 mL bottle
16 weeks (3 vials): 9 mL → 1 × 10 mL bottle

Alcohol Swabs: One for the vial stopper + one for the injection site each day.

Per week: 14 swabs (2/day)
8 weeks: 112 swabs → recommend 2 × 100‑count boxes
12 weeks: 168 swabs → recommend 2 × 100‑count boxes
16 weeks: 224 swabs → recommend 3 × 100‑count boxes

Protocol Overview

Concise summary of the once‑daily regimen.

Goal: Support physiological reproductive hormone signaling through upstream GnRH stimulation^[1].

Schedule: Daily subcutaneous injections for 8–12 weeks.

Dose Range: 100–200 mcg daily with gradual titration.

Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for precise low-volume measurements.

Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw.
