Explore our high-purity synthesized peptides and active pharmaceutical ingredients manufactured under strict cGMP protocol.
A comprehensive analytical breakdown of biochemical properties, solid-phase synthesis techniques, and strict quality control standards for enterprise procurement.
Pt141 (Bremelanotide) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH). Operating as a non-selective melanocortin receptor agonist (specifically targeting MC3R and MC4R within the central nervous system), Pt141 possesses a distinct cyclic structure linked via a disulfide bridge or lactam bond that grants high metabolic stability compared to linear peptides.
Utilizing high-throughput Solid-Phase Peptide Synthesis (SPPS) under rigorous temperature and atmospheric controls, our process ensures minimal racemization and high batch-to-batch consistency. Crude peptides undergo multi-stage preparative reverse-phase HPLC (RP-HPLC) purification to achieve pharmaceutical purity standard ≥ 99.0% with trifluoroacetic acid (TFA) exchange to acetate salt forms.
Every lot of OEM Pt141 10mg lyophilized powder undergoes exhaustive testing before release. Analytical documentation includes High-Performance Liquid Chromatography (HPLC) for chemical purity verification, Mass Spectrometry (MS) for precise molecular weight structure confirmation, Endotoxin Assay (LAL test < 0.05 EU/mg), and residual solvent mass spectrometry analysis.
Information Gain Insight: Unlike standard peptide brokers, our chemical manufacturing pipeline integrates specialized freeze-drying (lyophilization) protocols using automated Class 100 cleanroom lyophilisers. This guarantees a uniform cake structure with moisture content consistently below 1.5%, vastly extending shelf-life stability during international distribution.

Leveraging massive manufacturing scale, advanced automation, and integrated raw material sourcing to deliver cost-effective peptide APIs worldwide.
Our overall factory construction covers an impressive 250,000 square meters designed under strict international pharmaceutical architecture. This massive scale provides enterprise customers with scalable, highly flexible, and cost-effective peptide production capacity from gram-scale R&D up to multi-kilogram commercial batches.
By producing our own high-purity protected amino acids, coupling reagents, and specialized resin matrices in-house, Gentolex eliminates supply chain bottlenecks. This upstream integration drastically reduces production lead times and provides total trace-ability from basic chemical precursors to finished lyophilized vials.
Our modern cleanrooms house automated washing, subterranean filling, dynamic freeze-drying, and robotic crimping production lines. Operating under sterile Class 100 (ISO 5) laminar flow conditions, we guarantee vial sterility, uniform fill volumes (10mg per vial), and zero cross-contamination.
Customized contract manufacturing tailored for pharmaceutical brands, biotechnology firms, and institutional buyers.
We offer complete custom branding services for OEM Pt141 10mg orders. Options include customized flip-off caps (with brand logo engraving or custom color coding), high-precision custom labels, tamper-evident security seals, and protective secondary outer box packaging designed for cold-chain safety.
While 10mg lyophilized vials represent the industry standard, our facilities seamlessly support custom batch formulations. We can synthesize and package Pt141 at alternative strengths (such as 2mg, 5mg, or 15mg) or formulate customized multi-peptide blends based on specific institutional client specifications.
For international clients seeking localized finished dose manufacturing, Gentolex provides FDF (Finished Dosage Form) license out agreements, complete Master Batch Records (MBR), analytical method validation transfer documents, and technical setup consultation for regional laboratory assembly.
Navigating global regulatory frameworks with established regional hubs, regulatory documentation, and cold-chain logistics excellence.
To reduce international trade barriers and provide immediate communication, Gentolex Group has established active regional representative hubs in Mexico and South Africa. Serving clients across more than 10 countries, these localization centers handle localized customer service, regulatory clearance support, duty handling, and rapid regional inventory dispatch.
Every commercial batch is accompanied by comprehensive regulatory paperwork required for smooth customs processing and institutional verification. Documents include batch-specific Certificate of Analysis (COA), HPLC chromatograms, Mass Spectrometry curves, Material Safety Data Sheets (MSDS), and Certificate of Origin (COO).
Connecting the world with high-purity chemical products, API manufacturing, and complete technical services.
Gentolex’s goal is to create opportunities connecting the world with better services and guaranteed products.
