We bridge global pharmaceutical companies with peptide raw material suppliers, CDMO manufacturers worldwide, and Japan's leading healthcare facilities.
J & K L 株式会社 is a Tokyo-based consultancy focused on the global peptide and life sciences industry. We specialize in peptide raw material sourcing, CDMO matchmaking across China, Japan and beyond, and health management advisory. With deep roots in Asian and European markets, we connect clients worldwide with the best partners in peptide manufacturing and advanced healthcare.
Intermediary for global peptide API, intermediates and custom synthesis — connecting buyers with verified suppliers.
We specialize in connecting European, Japanese, and U.S. pharma companies with China-based peptide contract manufacturers — from SPPS specialists to GMP-certified commercial facilities.
We guide clients to Japan's leading stem cell clinics, anti-aging centers and premium wellness facilities.
Three specialized service pillars focused on the global peptide industry and life sciences ecosystem.
We act as trusted intermediaries sourcing peptide APIs, key intermediates, and custom synthesis materials — connecting global buyers with qualified suppliers at competitive prices.
We specialize in helping European, Japanese, and U.S. pharma and biotech companies identify and engage China-based peptide contract manufacturers — from clinical-stage SPPS specialists to large-scale commercial GMP facilities.
We provide personalized health management advisory and help clients access Japan's most advanced regenerative medicine and wellness facilities — including stem cell therapies and anti-aging programs.
A clear, bilingual process designed to move fast and reduce friction across borders.
We start with a focused conversation to understand your exact requirements, timelines, and compliance needs.
We draw from our verified supplier and CDMO network to identify the best-fit partners for your project.
We facilitate introductions, support due diligence, and provide bilingual negotiation throughout the process.
We stay engaged post-introduction to ensure smooth execution and address any issues that arise along the way.
Three things that set us apart in the global peptide and life sciences space.
Our team operates natively across three languages, eliminating miscommunication at every stage — from supplier negotiation in Mandarin to client reporting in English or German.
We focus exclusively on peptides and life sciences — not generalist sourcing. This means deeper supplier relationships, faster qualification, and sharper technical judgment on your behalf.
With roots in China, a base in Tokyo, and strong ties to European pharmaceutical markets, we bridge both directions: Asian manufacturers to European buyers, and vice versa.
Latest developments in the global peptide and GLP-1 drug market.
Our team combines deep expertise in pharmaceuticals, finance, and the Japanese healthcare market.
