What It Does
Six Reasons Clinicians Recommend PT-141
A synthetic melanocortin peptide that works centrally through the brain — not peripherally through blood flow — to naturally stimulate sexual desire and arousal in both men and women. Also known as Bremelanotide, the active compound in FDA-approved Vyleesi.
Stimulates Sexual Desire at the Brain Level
PT-141 activates melanocortin receptors (MC3R and MC4R) in the hypothalamus — the brain's primary regulator of sexual function. This central mechanism produces a genuine increase in sexual desire and motivation, addressing hypoactive sexual desire at its neurological source rather than managing downstream vascular symptoms. Effective in both men and women where desire — not physical function — is the primary concern.
Works Where Viagra & Cialis Cannot
PDE5 inhibitors like Viagra and Cialis address erectile dysfunction by increasing genital blood flow — but they have no effect on sexual desire and are ineffective when the underlying issue is neurological or psychological. PT-141 works through a completely independent mechanism, making it effective in patients who have not responded to PDE5 inhibitors and in women for whom no equivalent medication exists.
FDA-Approved for Women's Sexual Dysfunction
Bremelanotide (PT-141) is the active ingredient in Vyleesi — an FDA-approved treatment for hypoactive sexual desire disorder (HSDD) in premenopausal women. This makes PT-141 one of only two FDA-approved pharmacological treatments for female sexual dysfunction, and the only one that works via central nervous system activation rather than hormonal supplementation.
Effective for Both Men & Women
Clinical studies demonstrate PT-141's efficacy across sexes — in men it increases erectile response independent of PDE5 inhibition, while in women it increases genital arousal, lubrication, and subjective desire. Its central mechanism means it addresses the neurological component of sexual dysfunction that affects both sexes equally, regardless of hormonal status or underlying vascular health.
Addresses Psychological & Stress-Related Dysfunction
Sexual dysfunction driven by stress, anxiety, depression, or relationship factors often fails to respond to physical interventions. Because PT-141 activates desire pathways directly in the CNS, it can overcome the neurological suppression of libido caused by psychological stressors — producing arousal in contexts where the mind's inhibitory systems would otherwise block the response.
Fast Onset, No Daily Dosing Required
PT-141 is administered subcutaneously 45 minutes to 1 hour before sexual activity and produces effects that last 6 to 12 hours — without requiring daily dosing or scheduled timing around meals. Unlike daily-use medications, it is taken situationally, giving patients full flexibility without the need for ongoing systemic exposure or the lifestyle adjustments that daily medications require.
PT-141 vs Viagra: A Fundamentally Different Approach
Viagra and Cialis manage the physical mechanics of erection by increasing blood flow — they have no effect on desire. PT-141 works in the brain, activating the neurological pathways that generate sexual motivation and arousal in the first place. This makes them complementary rather than competing — and makes PT-141 uniquely effective in cases where desire, not physical function, is the underlying issue.

Why Lavi MD
Not All Peptide Brands Are Equal
Most peptide suppliers prioritize volume over patients. We were built differently — by a physician, for patients.

"Every product we offer is something I would prescribe to my own patients. Our formulations are designed for clinical outcomes — not marketing claims."
How We Operate
Built by a Physician, Not a Marketing Team
Lavi MD was founded under physician supervision. Every formulation, every dose, every protocol is reviewed by Dr. Moulavi before it reaches a patient — not outsourced to a contract manufacturer with no clinical input.
We Limit Shipping Days to Protect Your Product
We only ship Monday and Tuesday. That's a deliberate decision — it ensures your order arrives before the weekend and never sits in a carrier facility over two days without refrigeration. Most brands don't think that far ahead.
We Treat You Like a Patient, Not an Order Number
Our team includes clinical staff who understand what you're taking and why. If something goes wrong with your order — a warm shipment, a missing component, a question about your protocol — we fix it. No automated runaround.
