PT-141
Compounded Subcutaneous Injectable — Provider-Directed Dosing Protocol
PT-141, also known as Bremelanotide, is a melanocortin receptor agonist that has been studied for its role in sexual health and arousal signaling. Unlike vascular-mechanism compounds, it acts centrally through melanocortin receptors (MC3R and MC4R). Treatment decisions are made by licensed providers following a thorough clinical evaluation.
- ✓ Central mechanism — studied for its role at melanocortin receptors (MC3R/MC4R)
- ✓ Distinct from vascular-mechanism compounds — acts centrally through the nervous system
- ✓ Subcutaneous injection — provider-directed dosing and titration
- ✓ Compounded in an FDA-registered 503A pharmacy
- ✓ Provider evaluation included — clinical review before every prescription
Intro pricing — locked in for active program participants

The melanocortin receptor mechanism — how researchers are studying it
PT-141 works through a central mechanism — distinct from other approaches studied in sexual health research.
PT-141 has been studied for its activity at melanocortin receptors, specifically MC3R and MC4R. Research has examined how activation of these central receptors may relate to arousal signaling pathways.
Unlike vascular-mechanism compounds, PT-141 has been studied for its central nervous system activity. Research has examined its role in neural pathways associated with sexual response.
Research has examined PT-141’s receptor selectivity profile and its implications for tolerability. Studies have looked at its activity pattern across melanocortin receptor subtypes.
PT-141/Bremelanotide has been the subject of clinical research, including studies that contributed to FDA approval of a related formulation for HSDD in premenopausal women. Compounded PT-141 is available through licensed providers following individual clinical evaluation.
Quality Control
Every API tested 5 ways before it touches a vial.
The active pharmaceutical ingredients in your medication are tested at the API level — before compounding — across five independent quality markers.
Confirms you’re getting exactly the dose on the label. No underdosed vials.
Zero microbial contamination. Required for anything injected into the body.
Tests for bacterial byproducts that cause dangerous inflammatory responses.
Ensures the compound is stable and safe at the correct physiological pH.
Verifies there are no foreign substances, degradants, or unknown compounds present.
Member experiences.
Verified participants sharing their experience with the process and their provider-directed program.
“My provider was thorough and professional throughout the intake process. They explained the mechanism clearly and what to realistically expect. The FDA-registered pharmacy and real provider review were the trust signals I needed to move forward.”
“The discretion and professionalism of the whole process was exactly what I needed. My provider asked thoughtful questions, the intake was HIPAA-compliant, and the kit arrived discreetly packaged. No complaints.”
“What stood out was that my provider didn’t just approve me automatically — they reviewed my current medications and flagged a potential interaction to watch. That clinical diligence is what real telehealth should look like.”
What to expect
Every protocol works on its own timeline. Your provider will set expectations specific to your prescription.
Provider reviews intake carefully. Dosing is set based on your individual health profile.
Provider monitors response. Dosing may be adjusted based on individual tolerance and clinical status.
Provider reassesses protocol based on your response and any changes in health status.
Treatment continuation is determined by your licensed provider based on ongoing clinical evaluation.
Before you begin
A few things to know so you’re set up for a safe, provider-guided experience.
Administer only as directed by your provider. Your provider instructions will include guidance specific to your protocol — do not deviate from the prescribed schedule.
Store your vials refrigerated (36–46°F). Do not freeze. Keep out of direct light. Follow any specific storage instructions included with your kit.
Never mix with other medications in the same syringe. If you experience unexpected side effects, hold your dose and contact your provider before continuing.
Contact your provider or our support team before adjusting your protocol. Never self-escalate dosing without provider authorization.
Individual responses vary. Your provider will set timeline expectations specific to your prescription and health profile. Results are not guaranteed.
Your dosage is determined by your provider after reviewing your intake. You will not know your starting dose until after provider approval.
