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.
Define peptide sequence, purity targets, scale (grams → multi-kg), regulatory pathway (IND/NDA/GMP), and timeline.
We screen our growing network of China-based peptide CDMOs against your technical and compliance criteria, identifying the most suitable candidates for your project.
Remote document review (GMP certificates, analytical methods, batch records) followed by optional on-site audit at shortlisted facilities.
Facilitated introduction with bilingual support. We assist with NDA/CDA execution and initial feasibility discussions.
Bilingual negotiation support covering pricing, IP ownership, quality agreements, and delivery milestones until contract is signed.
Post-contract monitoring — milestone tracking, issue escalation, and communication bridging throughout the manufacturing campaign.
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.
Client submits recent medical check-up reports, bloodwork, and health goals. All records handled under strict confidentiality.
Our partnered physicians review the profile, identify key health indicators, and flag areas for further evaluation or treatment.
Based on the assessment, we propose a tailored program: stem cell therapy, anti-aging infusions, comprehensive health checks, or a combination package.
We match the client with the most suitable certified clinic in Tokyo or Osaka and handle all appointment scheduling and pre-arrival coordination.
Full bilingual concierge support during the clinic visit: interpretation, logistics, and real-time communication between client and medical team.
We coordinate follow-up consultations, track recovery progress, and advise on maintenance programs or next treatment cycles.
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.
