Kisspeptin (10mg) Injectable

• Supports Healthy Testosterone & Estrogen Levels: Promotes natural release of sex hormones via the HPG axis.
• Boosts Libido & Sexual Function: Improves arousal, interest, and sexual satisfaction in both men and women.
• Enhances Fertility: Encourages healthy ovulation and sperm production by increasing LH and FSH secretion.
• Restores Hormonal Rhythm: Useful for individuals experiencing hormonal disruption due to stress, travel, or overtraining.
• Improves Mood and Energy: By supporting hormonal balance, Kisspeptin can help stabilize mood and increase vitality.
• Gentle Hormone Optimization: Works upstream without shutting down natural hormone production, making it safer for long-term use.

• Pregnancy or Breastfeeding: Not recommended due to lack of safety data.
• Active or Hormone-Sensitive Cancer: Should not be used by individuals with a history of breast, ovarian, uterine, or prostate cancer.
• Endocrine Disorders: Those with pituitary or hypothalamic dysfunction should consult their provider before use.
• Known Allergy: Individuals with hypersensitivity to peptide-based therapies should avoid use.

Kisspeptin is considered very safe and well-tolerated. Mild, short-term effects can occasionally occur, including:

• Temporary injection site irritation
• Hormonal fluctuations (temporary changes in energy, menstrual cycle or libido) during titration
• Nausea or dizziness (usually resolves as the body adjusts)
• Anxiety or irritability if doses are increased too quickly

TIPS TO REDUCE SIDE EFFECTS

• Start Low: Begin with 5 units (≈0.1mg) to assess tolerance before increasing gradually.
• Follow Cycles Carefully: Use for 4 weeks, then take a 2–4 week break before restarting.
• Take at Consistent Times: Administer injections at similar times each week to maintain hormonal rhythm.
• Stay Hydrated: Proper hydration supports optimal peptide metabolism and reduces headaches.
• Avoid Overuse: More is not better — excess dosing may cause hormonal imbalance or overstimulation.
• Monitor Hormone Levels: Follow your provider’s recommendation for bloodwork every 4–8 weeks to ensure balance.
• Rotate Injection Sites: Helps prevent irritation and ensure even absorption.

Kisspeptin acts as a master regulator of reproductive hormones by stimulating the hypothalamus to release GnRH (Gonadotropin-Releasing Hormone). GnRH then signals the pituitary gland to release LH (Luteinizing Hormone) and FSH (Follicle-Stimulating Hormone) — the two key hormones that control testosterone, estrogen, ovulation, and fertility.

By supporting this natural hormone cascade, Kisspeptin helps restore optimal reproductive function, enhance libido, and promote balanced hormone production without shutting down the body’s natural feedback loop (as can occur with synthetic hormones). In both men and women, Kisspeptin may also improve mood, energy, and overall vitality through its effects on the hypothalamic-pituitary axis.

• 1–2 Weeks: Subtle increases in libido, mood, and general well-being. Some users notice a mild boost in energy and focus due to improved hormone signaling.
• 3–4 Weeks: Noticeable improvement in sexual interest, satisfaction, and hormonal balance. Men may experience increased morning testosterone levels, while women often report improved cycle regularity or ovulatory function.
• After 4 Weeks: Full benefits typically develop, including stronger libido, balanced mood, and improved reproductive hormone function. Follow-up bloodwork should be completed before adjusting the dose.
• Long-Term: Consistent use with proper cycling supports sustained hormonal health, fertility enhancement, and overall endocrine balance. Many users also report improved mood stability and natural energy over time.
