DIAGNOSEX, INC. is a California-based healthcare and life-sciences company founded in 2018. We bring together high-purity bio-raw material research, peptide and NCE CDMO services, and engineered pharmaceutical process equipment — under one accountable organization committed to advancing the life and health of patients worldwide.
DIAGNOSEX was founded on a simple conviction: better tools and better science lead to better patient outcomes. From a peptide and bio-raw material research line established in our earliest days, we have grown into an integrated group serving pharmaceutical manufacturers, CDMOs and research institutions across North America, Europe and Asia-Pacific.
Our in-house peptide R&D line focuses on medical-aesthetic and health peptide raw material R&D, leveraging our full industrial-chain advantages to deliver high-purity, high-activity bio-raw material solutions to global customers — from custom synthesis and preparative purification through lyophilized finished dosage forms.
In parallel, our process-equipment and CDMO division engineers, manufactures and operates the same preparative chromatography, fluid handling, aseptic fill–finish, lyophilization and vial-sealing platforms that we ship to GMP plants worldwide — giving every customer program the benefit of in-house process engineering.
Ensure the health and safety of people across the globe through rigorously engineered, responsibly manufactured life-sciences products.
Become a core driving force in the life and health field — bridging upstream bio-raw material research with downstream pharmaceutical manufacturing.
From research bench to commercial fill–finish line — every step is owned by a single organization that designs, qualifies and operates the platforms.
Every product and every platform is engineered to current GMP principles, with documentation, change-control and data-integrity evidence shipped as standard.
DIAGNOSEX develops both the bio-raw materials and the process equipment that transform them into finished, sterile dosage forms. Every platform is engineered, qualified and supported in-house.
In-house peptide sequences, from custom SPPS to modified residues and cyclization, for research and early-phase programs.
Dynamic axial-compression chromatography and process engineering, scaling from milligram reference lots to kilogram API batches.
GMP-compatible filling, stoppering and capping lines designed and built by our own equipment team for vial and lyophilized presentations.
In-house freeze-drying, analytical method validation, stability studies and batch release — all under one quality system.
DIAGNOSEX runs its own proprietary research and product line for medical-aesthetic and health peptide raw materials. Every sequence, process and batch is developed and quality-controlled in-house, delivering high-purity, high-activity bio-raw material solutions to global customers.
DIAGNOSEX unifies custom peptide synthesis, preparative purification and lyophilized formulation under one quality system — all capabilities built and operated by our own R&D and manufacturing teams, providing research institutions, CDMOs and pharmaceutical innovators with reliable, high-activity bio-raw materials.
1.Custom peptide synthesis — sequence design, SPPS, modified residues, cyclization
2.Preparative purification on the DAC800 dynamic axial-compression platform
3.GLP-1, regenerative, endocrine, dermatology and longevity peptide families
4.Process development, analytical method validation and stability support
5.For Research Use Only — supporting laboratory investigation and method development
From the bench to the production floor, these principles guide how we design, build and deliver — for our customers, our partners and the patients we ultimately serve.
Every product and process is judged by its impact on patient safety — from raw-material identity to finished-vial integrity.
GMP, data integrity and qualification are not add-ons — they are engineered into the platform from the first drawing.
We build the equipment we sell. The same engineers who design our platforms commission them on your floor.
Our peptide R&D and CDMO process teams keep us close to the bench — every platform evolves with the science it serves.
One quality system across three continents. One contract, one team, one point of accountability for your program.
We measure success by the number of customers who stay with us from feasibility through commercial supply.
DIAGNOSEX operates from San Diego, Shenzhen and Ås — connecting North American, Asia-Pacific and European customers to a single engineering, manufacturing and CDMO network. Visit us, schedule a virtual tour, or arrange a quality-system audit on request.
