Melanocortin Peptides (Bremelanotide) for Wellness
By Charles Kamen, MD, board-certified neurologist

melanocortin peptides (Bremelanotide) is a peptide that affects sexual function and arousal through melanocortin pathways. Dr. Charles Kamen, MD, board-certified neurologist at LiveNow Longevity in Las Vegas, offers melanocortin peptides therapy as part of comprehensive peptide protocols. Individual results vary.
What Are Melanocortin Peptides?
Melanocortin peptides are synthetic analogs of alpha-melanocyte-stimulating hormone (alpha-MSH). They act primarily on the melanocortin 4 receptor (MC4R), which is involved in sexual arousal and appetite regulation. [1]
Unlike PDE5 inhibitors (Viagra, Cialis) that act on vascular pathways, melanocortin peptides works through the central nervous system to enhance sexual desire and arousal.
Mechanism of Action
melanocortin peptides activates melanocortin receptors in the brain, particularly in areas involved in sexual function. This activation leads to increased sexual desire and arousal through central mechanisms rather than peripheral vascular effects. [2]
This central mechanism differentiates melanocortin peptides from other sexual enhancement medications.
Indications for melanocortin peptides Therapy
melanocortin peptides may be clinically appropriate for patients experiencing:
- Hypoactive sexual desire disorder (HSDD) in men and women
- Sexual arousal difficulties not responding to other treatments
- Libido concerns related to age or hormonal changes
- Sexual dysfunction related to antidepressant use
Research Evidence
Clinical trials demonstrate that melanocortin peptides effectively improves sexual function in both men and women with HSDD. Studies show increased arousal, desire, and satisfaction compared to placebo. [3]
However, individual responses vary, and results depend on the underlying cause of sexual dysfunction.
Administration and Dosing
melanocortin peptides are typically administered as a subcutaneous injection, usually 30-60 minutes before anticipated sexual activity. Some patients use it on an as-needed basis; others use scheduled dosing. [4]
Dr. Kamen determines the most appropriate dosing protocol based on individual response and treatment goals.
Key Takeaways
- melanocortin peptides works through melanocortin pathways in the central nervous system
- It enhances sexual desire and arousal through central rather than vascular mechanisms
- Available as subcutaneous injection, typically 30-60 minutes before activity
- Effective for hypoactive sexual desire disorder in men and women
- Results vary based on underlying cause and individual factors
- Dr. Kamen evaluates candidacy and monitors response throughout therapy
Common Questions
How is melanocortin peptides different from Viagra or Cialis?
Viagra and Cialis work on vascular pathways to improve erectile function. melanocortin peptides works on central nervous system pathways to enhance sexual desire and arousal. They work through completely different mechanisms.
Does melanocortin peptides work for women?
Yes. melanocortin peptides are FDA-approved for hypoactive sexual desire disorder in women (marketed as Vyleesi). Dr. Kamen offers this therapy for appropriate candidates.
What are the side effects of melanocortin peptides?
Common side effects include nausea, flushing, and headache. These are typically mild and transient. Dr. Kamen monitors for adverse effects.
How often can I use melanocortin peptides?
Dosing frequency depends on individual response and goals. Dr. Kamen establishes appropriate dosing schedules for each patient.
Is melanocortin peptides safe for long-term use?
Long-term safety data is limited. Dr. Kamen evaluates ongoing therapy based on individual response and benefit-risk assessment.
Can melanocortin peptides be combined with other therapies?
melanocortin peptides may be combined with other peptide or hormone therapies when clinically appropriate. Dr. Kamen evaluates each case to ensure safe combination protocols.
melanocortin peptides offers a unique approach to sexual dysfunction through central melanocortin pathways. Consult with Dr. Kamen to determine whether melanocortin peptides therapy is appropriate for your situation.
