What is PT-142?
Plain language first. The technical label stays, but it never stands alone.Overview
A number that looks like it continues Palatin's series, with no compound published behind it. PT-141 is the real one and it has an approved label.
No molecule corresponding to the designation PT-142 is characterized in public sources. PT-141 (bremelanotide) is FDA-approved as Vyleesi, and the designation PT-14 appears in patent literature for Melanotan II. This entry records the absence rather than inferring a structure.
What it's used for
A name sold as a successor to PT-141. No published characterization of the compound exists.
How does PT-142 work?
What it does in the body, and where.Palatin Technologies used PT numbers for its melanocortin program, which is what makes the name persuasive.
- 01PT-141 is bremelanotide, and it is approvedFDA approved as Vyleesi in 2019 for hypoactive sexual desire disorder in premenopausal women. Sequence, patents and phase III trials all exist.
- 02PT-14 was Melanotan IIPatent literature records Melanotan II under the designation PT-14 during its development as Erectide. The numbering is real, and it belongs to specific molecules.
- 03No record attaches to PT-142No sequence, formula, patent or trial for a compound with this designation could be located. A plausible next number in a real series is not the same as a compound.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.
- Sexual function, by implication of the namenone

Four things to know about PT-142
How much, and do you cycle it?
The range, and whether you take breaks.Research only, not established. Not established No range
No schedule has been studied for this compound in people.
Nothing publishedNo figure
No half-life can be published for a compound with no established identity.
You can compare this against the whole library to see where it sits.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
Choose your mix
Measuring the water1 mL = one full 100-unit syringe.
How do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized PT-142 keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.
What are the side effects and cautions?
Known cautions and warnings for this compound.Who should avoid it
- Pregnancy or breastfeeding
- Uncontrolled high blood pressure or known cardiovascular disease, a documented concern for this drug class
- Anyone unable to confirm from a certificate of analysis what molecule they have
- Anyone who wants established safety data, because none exists for this compound in humans
Stop and get help
- Signs of an allergic reaction, including spreading hives, facial or throat swelling, or trouble breathing
- Redness, heat, or pus at the injection site, which can signal infection
- Anything unusual, since there is no known safety profile to compare it against
Common effects
- Unknown. No study has recorded what this commonly causes, because the compound is not identified
Where this page says nothing is established, that means nobody has studied it, not that a compound is safe.
