PT-141 10 mg

Dragon Pharma PT-141 10 mg – Synthetic Melanocortin Agonist for Research

Dragon Pharma PT-141 (Bremelanotide) is a synthetic cyclic peptide analogue of alpha-melanocyte-stimulating hormone (alpha-MSH). It acts as a selective agonist of melanocortin receptors, particularly MC3-R and MC4-R, which are involved in sexual function and appetite regulation. Unlike its predecessor Melanotan 2, PT-141 was specifically developed to minimize MC1-R activation (melanogenesis/tanning) while retaining effects on MC3-R and MC4-R, making it a more targeted research tool for studying these pathways.

If you're looking for legit PT-141 for research purposes, this peptide has gained attention for its potential effects on sexual function through central nervous system pathways — distinct from peripheral vasodilators like PDE5 inhibitors (Viagra, Cialis). For researchers studying sexual behavior, melanocortin receptor pharmacology, or CNS-mediated effects on arousal, PT-141 offers a selective research tool.

Why Athletes & Bodybuilders Are Researching PT-141

Sexual health and libido are important quality-of-life factors that can be affected by intense training, hormonal fluctuations, or stress. PT-141 research focuses on its potential to influence sexual function through central melanocortin pathways, offering a mechanism distinct from traditional PDE5 inhibitors. For researchers studying the CNS regulation of sexual behavior or melanocortin receptor pharmacology, PT-141 provides a well-characterized selective tool.

What Makes Dragon Pharma PT-141 Different?

• ✔ Selective MC3-R/MC4-R agonist — minimal melanogenic effects
• ✔ Developed specifically for sexual function research
• ✔ Distinct mechanism from PDE5 inhibitors (central vs peripheral)
• ✔ Well-characterized in clinical research literature

Note for researchers: PT-141 is a selective melanocortin agonist distinct from Melanotan 2. For best results in your research, follow established protocols and always source PT-141 from verified suppliers like Dragon Pharma.

Product Specifications

Dosage, Reconstitution & Research Guidelines

Reconstitution Instructions (10 mg Vial)

PT-141 comes as a lyophilized powder in a 2 mL sterile vial. You'll need bacteriostatic water to reconstitute it properly.

• ✔ Add 2 mL of bacteriostatic water to the vial
• ✔ Final concentration: 5 mg per mL (5000 mcg/mL)
• ✔ Gently swirl — do not shake
• ✔ Refrigerate after reconstitution and use within 14 days

Typical Research Dosing

Based on available research literature, typical PT-141 dosing in animal studies falls in this range:

• ✔ 0.1 – 1.0 mg per kg in research models
• ✔ Typical research dose: 0.5 – 2.0 mg per injection depending on model
• ✔ One 10 mg vial provides approximately 5-20 research doses depending on dose
• ✔ Dosing frequency is typically as-needed or weekly depending on study design

Insulin Syringe Dosing Guide

Using a standard 1 mL (100 unit) insulin syringe with PT-141 reconstituted to 5 mg/mL (5000 mcg/mL):

• ✔ 0.05 mL (5 units) = 250 mcg
• ✔ 0.10 mL (10 units) = 500 mcg
• ✔ 0.20 mL (20 units) = 1000 mcg (1.0 mg)
• ✔ 0.30 mL (30 units) = 1500 mcg (1.5 mg)
• ✔ 0.40 mL (40 units) = 2000 mcg (2.0 mg)
• ✔ Administer subcutaneously — abdomen area

How Researchers Are Using PT-141

PT-141 is a selective MC3-R/MC4-R agonist developed specifically for sexual function research. Unlike Melanotan 2 which also activates MC1-R (tanning), PT-141 offers a more targeted receptor profile.

Popular research stacks include:

• ✔ PT-141 + Melanotan 2 — for comparative melanocortin receptor research (selectivity vs. non-selectivity). View Melanotan 2 →
• ✔ PT-141 + PDE5 inhibitors (research compounds) — for comparative pathway studies (central vs. peripheral)
• ✔ PT-141 + Kisspeptin — for HPG axis and melanocortin research. View Kisspeptin →

Research Protocol Example (As-Needed Study)

• ✔ Single-dose administration: PT-141 0.5-1.5 mg subQ as needed per protocol
• ✔ Observation window: Monitor effects for 6-12 hours post-administration
• ✔ Washout period: Minimum 24-48 hours between doses in repeated measures designs

Important Considerations

• 🔬 PT-141 is a selective MC3-R/MC4-R agonist — minimal melanogenic effects compared to Melanotan 2
• 💧 Works through central nervous system pathways — distinct from peripheral vasodilators
• ⚠️ Well-characterized in clinical research with a distinct side effect profile
• 📦 Always source PT-141 from verified suppliers like Dragon Pharma

Lab Verification – Third-Party Testing (Coming Soon)

At Dragon Pharma, every batch of PT-141 is scheduled for independent third-party HPLC testing to verify purity, mass, and sterility. The report for the current batch is in progress and will be published here as soon as it's available.

What Will Be Tested?

Why Third-Party Testing Matters

With the rise of counterfeit research peptides, independent lab verification is the only way to confirm you're getting what you paid for. PT-141 should meet strict purity and mass standards. Dragon Pharma commits to full transparency — as soon as each batch is tested, the COA will appear here with:

• ✔ HPLC chromatogram (visible peak purity)
• ✔ Measured mass vs label claim (10 mg)
• ✔ Batch number for traceability
• ✔ Test date and lab accreditation

Storage Guidelines

Before Reconstitution (Lyophilized Powder)

• ✔ Store at 2–8°C (36–46°F) — standard refrigerator temperature
• ✔ Do not freeze the lyophilized powder
• ✔ Keep in original packaging, away from light
• ✔ Stable for up to 12 months when refrigerated properly
• ✔ Avoid repeated temperature changes (don't take in and out of fridge unnecessarily)

After Reconstitution (Mixed with Bacteriostatic Water)

• ✔ Store at 2–8°C (36–46°F)
• ✔ Use within 14 days of reconstitution
• ✔ Do not freeze after reconstitution — freezing can damage peptide structure
• ✔ Keep vial upright and sealed between uses
• ✔ Avoid direct light exposure

What to Avoid

• ❌ Freezing (before or after reconstitution — damages peptide bonds)
• ❌ Leaving at room temperature for extended periods (>24 hours)
• ❌ Shaking the vial — swirl gently instead
• ❌ Using cloudy or particulated solution after reconstitution
• ❌ Storing in bathroom or near heat sources

Inspection Before Use

Before using in your research, always inspect the vial:

• ✔ Lyophilized powder should appear as a white, intact cake or powder — not yellow, clumped, or melted
• ✔ After reconstitution, solution should be clear and particle-free
• ✔ Crimp seal must be intact — do not use if seal is broken or missing
• ✔ Check batch number and QR code for authenticity before use

Keep out of reach of children and unauthorized personnel. Follow institutional laboratory safety guidelines for handling research peptides.
