PT-141 by Dragon Pharma
What Is PT-141?
PT-141 from Dragon Pharma is an injectable peptide whose active substance is bremelanotide. Unlike erection drugs that work on blood flow, bremelanotide acts on melanocortin receptors in the central nervous system, which is the pathway behind sexual desire and arousal. Instead of only helping the body respond physically, it targets the brain signals that start the response in the first place.
In research and wellness settings PT-141 is studied for low libido, loss of sexual desire, and as a companion to PDE5 treatments such as Viagra and Cialis. A form of bremelanotide is FDA approved for hypoactive sexual desire disorder in women, and the peptide is widely researched off-label for men. Reported effects include stronger arousal, improved sexual motivation, and greater confidence in intimate situations.
Each vial from Dragon Pharma holds 10 mg of bremelanotide as a peptide that is prepared per the label before research use. This page is a research reference: PT-141 products are sold for laboratory and research purposes and are not approved for human use.
PT-141 Research Use
PT-141 is dosed from a 10 mg vial that is reconstituted with bacteriostatic water before use. A common reference dilution is 2 ml of diluent per 10 mg vial, giving a 5 mg/ml concentration from which small research doses are drawn. Prescribing information for bremelanotide states a single adult dose of 1.75 mg and limits use to one dose per 24 hours.
| Research Dose | Volume at 5 mg/ml | Reference |
|---|---|---|
| 0.5 mg | 0.1 ml | Low-dose response testing |
| 1 mg | 0.2 ml | Common research reference for men |
| 1.75 mg | 0.35 ml | Approved single-dose reference |
Protocol Notes
Effects are reported within about an hour of dosing and arousal benefits can last for several hours. Do not exceed one dose in any 24 hour period. Because nausea is dose dependent, most protocols start low and adjust only after the response is known.
Handling and Storage
Reconstitute only with bacteriostatic water using sterile technique. Store the reconstituted peptide refrigerated and protected from light, and discard any vial that is cloudy or past its use window.
PT-141 Stacks
PT-141 is a central arousal peptide, so in research protocols it is usually paired with compounds that handle the physical response side and the hormonal environment side of sexual health. All links below are from the same Dragon Pharma line and are shown as research references.
| Stack Partner | Role in the Stack |
|---|---|
| Levitra | PDE5 partner covering erection quality while PT-141 handles desire. |
| Cialis DP | Longer-acting blood-flow support combined with central arousal drive. |
| Proviron | Androgen-tone support for confidence and libido during on-cycle phases. |
| Enclomiphene | Hormonal-normalization reference for libido recovery after cycles. |
| HCG 5000 IU | Testicular signaling support in long testosterone-based programs. |
PT-141 Side Effects
The most common side effect of PT-141 is nausea, and it is dose dependent: at low research doses most subjects tolerate it well, while higher doses bring more queasiness. Facial flushing, headache, and a temporary rise in blood pressure are also reported. These effects are usually short lived and tied to the dose.
- Nausea: the most common effect, worse at higher doses.
- Facial flushing: frequent and usually brief.
- Headache and dizziness: reported at moderate and higher doses.
- Blood pressure increase: real risk in predisposed individuals.

What is PT-141 from Dragon Pharma?
PT-141 is an injectable research peptide from Dragon Pharma containing bremelanotide, 10 mg per vial. Bremelanotide is a melanocortin receptor agonist that acts in the central nervous system to increase sexual desire and arousal.
How is PT-141 different from Viagra or Cialis?
Viagra and Cialis are PDE5 inhibitors that work on blood flow to produce an erection. PT-141 works centrally on the brain pathways behind desire and arousal, so it is often described as targeting the want rather than just the mechanics.
How long does it take for PT-141 to work?
Most reports place the onset of PT-141 within about an hour of dosing. The desire and arousal effect can last for several hours, and dosing is limited to one dose per 24 hour period.
How much PT-141 should I take?
Research references usually range from 0.5 mg for low-dose response testing to 1 mg as a common starting point and 1.75 mg as the approved single-dose reference. Dosing should start low because nausea is dose dependent.
Does PT-141 cause nausea?
Nausea is the most common side effect of PT-141 and it is dose dependent. At 1 mg most people tolerate the peptide well, while higher doses such as 2 mg bring noticeably more queasiness.
How long does PT-141 last?
The clinical effects on desire and arousal typically last several hours, with some users reporting benefits that persist for a day or more. Effects and duration vary by dose and individual response.
Can women use PT-141?
Yes. A form of bremelanotide is approved for hypoactive sexual desire disorder in women, and PT-141 is widely studied for female sexual dysfunction. Its central mechanism makes it relevant for desire issues in both men and women.
Who should not use PT-141?
Bremelanotide raises blood pressure, so people with uncontrolled hypertension or cardiovascular disease should not use PT-141. It should also not be combined with MAO inhibitors or with more than one dose per day.
How do I reconstitute PT-141?
Reconstitute the 10 mg vial with bacteriostatic water using sterile technique. A common reference dilution is 2 ml, giving a 5 mg/ml concentration from which research doses are drawn with an insulin syringe.
Is PT-141 approved for human use?
A prescription form of bremelanotide is approved for specific medical use, but research-grade PT-141 from Dragon Pharma is sold for laboratory research only and is not approved as a self-administered medicine.
