Your protocol

How Kisspeptin is prescribed.

Who it's for
  • Adults whose physician is supporting natural hormone signaling
  • Patients focused on libido and reproductive-hormone health

Your physician decides whether Kisspeptin is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.25 mL (25 units) subcutaneously once daily Monday through Friday.

Cycle. A few times per week at your physician's direction.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.
What's included
  • Licensed physician review of your intake, history, and labs
  • Medication compounded to your prescription by a PCAB-accredited, FDA-registered pharmacy
  • Every batch independently tested before release
  • Sterile syringes and alcohol prep pads for injectables
  • Tracked delivery to your door, refills on schedule
  • Message your physician anytime; dose changes without an appointment
Storage & handling
  • Store refrigerated (36–46°F / 2–8°C) at all times, including before first use.
  • One vial is your monthly supply. A fresh vial ships every 28 days on your refill schedule, so you're always well inside the beyond-use date on your label.
  • Protect from light. Wipe the stopper with an alcohol pad before every draw.
  • Dispose of syringes in the sharps container per the included instructions.
What to expect

The science

How Kisspeptin works, and what the research shows.

How it works

Kisspeptin is an upstream regulator of GnRH (gonadotropin-releasing hormone).

It naturally stimulates testosterone and estrogen production through the body's own pathways, enhancing desire through hormonal optimization.

Clinical evidence
  • Human physiology studies show kisspeptin infusion stimulates LH pulses and downstream testosterone in men, and research groups (notably Dhillo and colleagues in the UK) have run controlled human studies exploring its role in reproductive hormones and sexual desire, including brain-imaging trials in hypoactive sexual desire.

  • No kisspeptin product is FDA-approved; clinical use is investigational and physician-directed.
