The per-mg and multi-vial math is broken down on the PT-141 price per vial page. The PT-141 dosage page reports what the trials used, as research figures rather than instructions, and the complete PT-141 guide covers the research in full. The reconstitution calculator does the arithmetic for mixing the vial with bacteriostatic water and reports it in units rather than mL.

Before you buy
What should you check before you buy PT-141?
Check that the certificate proves the batch is PT-141, not only that the sample is pure, and that it states the peptide actually measured in the vial. The released batch, lot PT1-260411-A, shows identity by HPLC-RTM + LC-MS with a measured mass of 1025.2 Da, 99.12% purity by HPLC against a not-less-than 95.0% release criterion, and 10.18 mg of net peptide in a 10mg vial.
- Identity, not only purity. A purity figure says a sample is mostly one peptide; the LC-MS identity result and its measured mass are what say that peptide is PT-141.
- Research grade is not the approved product. Bremelanotide is sold as an approved medicine under its own label. A research vial is a different product, so compare it with other research vials on their certificates.
- The rest of the panel. Titreon Analytical's certificate also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen for the batch.
- Your own batch. Vials ship unlabeled on purpose, so verification runs on your order number. Message us on WhatsApp with it and we will confirm your batch and send its published certificate.
The checks that apply to any seller are in how to verify peptide purity, and the full certificate for this batch is on the PT-141 certificate card.
The short answer
What is PT-141 (bremelanotide)?
PT-141, also called bremelanotide, is a melanocortin receptor agonist studied for low libido and sexual arousal in both men and women (Molinoff et al., 2003). Unlike erectile-dysfunction medications that work on blood flow, it acts centrally, on arousal pathways in the brain, which is why it has been studied for desire rather than mechanics alone. The phase 3 RECONNECT trials in premenopausal women used a single fixed 1.75 mg subcutaneous dose taken as needed rather than daily (Kingsberg et al., 2019), and bremelanotide is the active ingredient in the FDA-approved product Vyleesi. Peptara supplies research-grade PT-141 as a lyophilized 10mg vial for laboratory research; the figures here describe what published studies reported, not a dose for any person, and a qualified clinician sets any personal plan.
The Science
Arousal That Starts in the Brain
Most well-known performance medications work on blood flow. PT-141 takes a different route entirely, acting on melanocortin receptors in the central nervous system that govern desire and arousal. That is why it has been studied for both men and women.
Central Mechanism
Acts on brain arousal pathways rather than on blood vessels.
Both Sexes
Studied in men and women, with an FDA-approved version for women.
Desire, Not Just Function
The studied endpoints are libido and arousal, which is a different mechanism from blood-flow medications.
Applications
Common Use Cases
Low Libido
Reduced desire is the research area, in both sexes, where the central mechanism is the one studied.
Arousal Support
Studied for arousal that begins with desire rather than blood flow alone.
Couples Use
Reported anecdotally rather than studied. No trial measured couples as a unit.
As-Needed Tool
The trials dosed it as needed rather than daily, which is the published pattern.
Dosage as studied
What doses did PT-141 studies use?
The clearest PT-141 dosing figure comes from the phase 3 RECONNECT trials in premenopausal women, which used a single fixed 1.75 mg subcutaneous dose taken as needed rather than on a daily schedule (Kingsberg et al., 2019). Earlier research explored other routes and populations: a placebo-controlled dose-finding trial evaluated bremelanotide in premenopausal women (Clayton et al., 2016), and an early double-blind study assessed an intranasal form of PT-141 in healthy men and men with mild-to-moderate erectile dysfunction (Diamond et al., 2004).
| Study or setting | Population | What it reported about dosing | Source |
|---|---|---|---|
| Phase 3 RECONNECT | Premenopausal women | A single fixed 1.75 mg subcutaneous dose, taken as needed rather than daily | Kingsberg et al., 2019 |
| Phase 2 dose-finding | Premenopausal women | A placebo-controlled evaluation across a range of doses | Clayton et al., 2016 |
| Early PK/PD study | Healthy men and men with mild-to-moderate ED | Evaluated an intranasal form of PT-141 | Diamond et al., 2004 |
| Vyleesi label | FDA-approved use | Carries a dosing-frequency cap, the only regulated frequency guidance | Vyleesi Prescribing Information |
There is no PT-141 dosage chart or calculator that converts these study figures into a personal dose. A lyophilized 10mg research vial is reconstituted with bacteriostatic water, and the reconstitution calculator on this site reports concentration in units rather than mL. For the full breakdown of what the trials reported, see the PT-141 dosage page. Picking a dose is a decision for a licensed clinician, not something to copy from a trial protocol.
Nasal spray vs injection
Is PT-141 a nasal spray or an injection?
Both forms appear in the research record, which is why searches split between a PT-141 nasal spray and an injection. The earliest clinical work used an intranasal formulation, studied in healthy men and men with mild-to-moderate erectile dysfunction (Diamond et al., 2004). Development later moved to subcutaneous injection: the FDA-approved product Vyleesi is delivered subcutaneously, and the phase 3 RECONNECT trials used a subcutaneous dose (Kingsberg et al., 2019).
Peptara supplies research-grade PT-141 as a lyophilized powder in a sealed 10mg vial, not as a pre-mixed nasal spray or a ready-to-use pen. How reconstituted material is handled is a laboratory matter, and any route of administration in people is a conversation for a licensed clinician.

The trial dose
The RECONNECT phase 3 trials used a single fixed 1.75 mg subcutaneous dose, taken as needed rather than daily (Kingsberg et al., 2019).
Label caps
The approved product Vyleesi carries dosing frequency caps on its label, which is the only regulated frequency guidance that exists for this molecule (Vyleesi Prescribing Information).
Reported effects
Nausea and facial flushing were among the most commonly reported effects in the trial programme, reported as dose related (Kingsberg et al., 2019).
Research grade
Bremelanotide is the active ingredient in Vyleesi, so the names point to the same molecule. Research-grade PT-141 is sold for laboratory research and is not the approved product.

Buying PT-141: FAQ
Where can I buy PT-141 peptide online?
Peptara Labs sells PT-141 online as a 10mg research-grade vial, ordered from this page. Research-grade PT-141 is sold for laboratory research use and is not the approved product, so the batch certificate is the thing to compare between sources.
How much does PT-141 cost?
One 10mg vial is $140 USD, which is $14.00 per mg. Signing up by email takes 15 percent off a first order, which brings a vial to $119. Buying more of the same compound lowers the per-vial price on that line, to 40 percent off at 10 vials, which is $84 each.
Does Peptara Labs ship PT-141 to the US?
Yes. Orders to the United States, Canada, the United Kingdom and New Zealand ship tracked in 5 to 10 business days, guaranteed. Shipping is a flat $35, free over $250.
How do I verify the purity of PT-141 before I buy?
Read certificate COA-2026-7459 for the released batch, lot PT1-260411-A: 99.12 percent purity by HPLC, identity by HPLC-RTM + LC-MS with a measured mass of 1025.2 Da, and 10.18 mg of net content in a 10mg vial, tested by Titreon Analytical, whose panel also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen. Vials ship unlabeled, so your order number on WhatsApp is what ties your vial to its batch certificate.
Is PT-141 the same as bremelanotide?
Yes, the names point to the same molecule. Bremelanotide is the active ingredient in Vyleesi, the approved medicine, which is a regulated product with its own label. Research-grade PT-141 in a lyophilized vial is sold for laboratory research and is not that product.
What comes with a PT-141 order?
One sealed 10mg vial of lyophilized PT-141 and bacteriostatic water to reconstitute it, plus a printed reference guide to what published studies reported. The batch certificate is published on the certificates page, because the vial itself ships unlabeled.
Is PT-141 for human use?
No. Research-grade PT-141 is sold for laboratory research use only, not for human use. The approved bremelanotide medicine is a separate, prescribed product.
PT-141 FAQ
What is PT-141 and how does it work?
PT-141, also called bremelanotide, is a melanocortin agonist studied for libido and sexual arousal in both men and women. What makes it distinctive is that it works centrally, through the nervous system and arousal pathways in the brain, rather than vascularly the way erectile-dysfunction medications do. That central mechanism is why it is studied for desire and arousal, not just physical function, and why it can apply to women as well as men.
Is it FDA-approved?
Bremelanotide is FDA-approved under the brand name Vyleesi for a specific condition (hypoactive sexual desire disorder in premenopausal women), which gives the molecule clinical grounding. Peptara supplies research-grade PT-141, and we are transparent that our product is for research use and is distinct from the approved branded pharmaceutical. If you are treating a diagnosed medical condition, that is a conversation for your doctor.
Is Peptara Labs a real company?
Yes. Peptara Labs is a registered business with responsive customer support via WhatsApp. Unlike anonymous Telegram sellers, we stand behind every order with our name, reputation, and ongoing support.
Are your peptides real?
Every PT-141 vial comes with a third-party Certificate of Analysis (COA) confirming 98%+ purity. We source from verified manufacturers and can provide lab documentation upon request. If you want to see a COA before ordering, message us on WhatsApp and we'll send it over.
Will the peptides survive shipping and heat?
Yes. Peptides ship in their lyophilized (freeze-dried powder) form, which is stable at room temperature for weeks. Fast, tracked delivery keeps transit short. Once reconstituted with bacteriostatic water, store the vial in your refrigerator. Storage instructions are included with every order.
How is PT-141 dosed?
The published figure is a single fixed 1.75 mg subcutaneous dose taken as needed rather than daily, which is what the RECONNECT phase 3 trials used (Kingsberg et al., 2019). Nausea in that programme was reported as dose related. The approved product Vyleesi carries frequency caps on its label. Those are the reference points that exist; picking a dose is a decision for a licensed clinician.
Does it work for women too?
Yes. Because bremelanotide acts on central arousal pathways rather than on blood flow, it has been studied in both sexes, and the FDA-approved product is indicated for women. Peptara Labs supplies research-grade material and does not advise on dosing.
Is PT-141 studied for men?
Yes. The earliest clinical work on PT-141 evaluated an intranasal form in healthy men and in men with mild-to-moderate erectile dysfunction (Diamond et al., 2004), and its central, melanocortin mechanism applies across both sexes (Molinoff et al., 2003). The FDA-approved product Vyleesi is indicated for premenopausal women, so the approved use and the male research base are not the same thing. Peptara Labs supplies research-grade material and does not advise on dosing.
Is there a PT-141 nasal spray?
A nasal form exists in the research literature: the first clinical studies used intranasal PT-141 (Diamond et al., 2004) before development shifted to subcutaneous injection, which is how the approved product Vyleesi and the phase 3 RECONNECT trials delivered it (Kingsberg et al., 2019). What ships here is a lyophilized 10mg vial for laboratory research, not a pre-made nasal spray. Any route of administration in people is a decision for a licensed clinician.
What about side effects?
The most commonly reported effects are nausea and facial flushing, reported as dose related, and a temporary headache. Mild, temporary skin darkening is also reported, through the melanocortin pathway. Uncontrolled high blood pressure or a cardiovascular condition is a reason to involve a clinician before anything else. Any dosing schedule is a decision for a licensed clinician.
How is the 10mg vial reconstituted?
Reconstitution is arithmetic: the milligrams in the vial divided by the millilitres of bacteriostatic water added to it. The reconstitution calculator on this site does that math and reports the result in units rather than mL. Storage instructions ship with every order. For anything medical, including how a compound is administered, speak with a licensed physician.
