01

Desire, from the brain.

PT-141 (bremelanotide) works on melanocortin receptors in the brain rather than on blood flow - a different route to sexual response than the familiar vascular drugs. It is one of the few compounds here with an actual approval behind it.

01
Central, not vascular
Acts on brain melanocortin (MC4R) pathways, not blood flow like PDE5 inhibitors.
02
An approved use
FDA-approved as Vyleesi for low sexual desire in premenopausal women.
03
Studied in both sexes
Research and real-world use spans men and women.

Where the research focuses.

What it's studied for

01
Sexual desire

Its approved use - improving low desire (HSDD) in premenopausal women in controlled trials.

02
Erectile response

Studied in men for arousal via the central pathway rather than blood flow.

03
Central arousal

Acts on brain MC4R circuits tied to sexual motivation.

04
Non-vascular option

Researched where blood-flow drugs are unsuitable or ineffective.

05

A different route to arousal.

Most arousal drugs work on blood flow. PT-141 instead signals through brain melanocortin receptors involved in sexual motivation - which is why it is studied for desire, not just physical response. It began as a by-product of the tanning peptide Melanotan II, then was developed on its own and approved for one specific indication.

Tier 01
Strongest support
  • FDA approval for HSDD (Vyleesi)
  • Melanocortin-receptor mechanism characterised
  • Controlled-trial efficacy for desire
Tier 02
Moderate support
  • Male erectile-response research
  • Dose–response and tolerability data
Tier 03
Emerging / unverified
  • Long-term off-label use
  • Recreational dosing claims

How it works

01
MC4R agonism

Activates brain melanocortin-4 receptors tied to sexual motivation.

Characterised

Reconstitution calculator

How much diluent to mix into the vial, and the concentration that results. The suggested volume reaches a clean working stock; the calculator does the arithmetic from figures you enter. These describe solution preparation for research handling — not instructions for use in humans or animals.

Suggested reconstitution Reconstitute the 10 mg vial with 2 mL bacteriostatic water → 5.0 mg/mL (5000 mcg/mL)

Concentration = compound ÷ diluent. Volume per aliquot = target ÷ concentration. U-100 units are a volume readout (1 mL = 100 units). Figures are for research solution preparation only — not instructions for use in humans or animals.

Signs of a quality compound

Lyophilised cake or powder
A fine, fluffy white cake — not oily, clumped or discoloured.
Clear reconstitution
Dissolves to a clear, colourless solution with no visible particles or cloudiness.
Batch-specific COA
Independent HPLC purity and mass-spec identity for the exact lot — not a recycled generic PDF.
Intact seal & vacuum
Sealed flip-top vial under vacuum; correct fill; legible batch and storage marking.
Walk away if…
No COA, oily residue, off-colour, partial vacuum, or purity claims with no independent test behind them.
Suspiciously cheap
Pricing far below the market for a well-tested compound usually means skipped testing or underfilled vials.
Regulatory & status
Approved, but narrow.

PT-141 is FDA-approved as Vyleesi for one specific indication. Outside that, it is used off-label and sold as a research material. Common side effects include nausea, flushing and short-lived blood-pressure increases.
