Global GLP-1 Comparator Sourcing
Demand for GLP-1 receptor agonists continues to grow across clinical development, with studies investigating obesity, type 2 diabetes, cardiovascular disease and additional metabolic indications. As demand increases, securing reliable comparator supply has become increasingly important for sponsors.
CSI has extensive experience sourcing GLP-1 comparator medicines, including Ozempic® (semaglutide), Wegovy® (semaglutide) and Mounjaro® (tirzepatide), supporting biotechnology, pharmaceutical and CRO clients with compliant global supply strategies.
GLP-1 Agonist Comparator Sourcing
The clinical supply partner of choice
GLP-1 receptor agonists are on the critical path of metabolic and cardiometabolic programmes worldwide, and market-wide demand routinely outstrips the volume available through a single market. Sponsors running multi-country studies need a partner who can hold continuity of supply across regions, not a broker who can fulfill one order.
CSI's scientific team builds the sourcing strategy around your protocol: which presentations the sites require, which markets can supply them compliantly, and how far ahead the volume has to be secured. That work is what keeps a study on schedule when the market tightens. Every unit arrives with the documentation your QP and regulatory teams expect, sourced through qualified manufacturers and wholesalers inside a fully traceable chain.
Our team provides:
Global comparator sourcing
Sourcing across multiple markets for obesity, diabetes and cardiometabolic programmes.
Forecast planning for high-demand medicines
Volume secured ahead of enrolment, which matters most where market demand is tight.
Temperature-controlled logistics
GDP-compliant cold chain with continuous monitoring from source to site.
Regulatory documentation and product authentication
The full documentation set, plus authentication of every unit supplied.
Multi-country supply management
One coordinated strategy across every participating market.
THE CSI PROCESS
From protocol to site in six steps
Six steps, one project manager providing end-to-end support.
01
Protocol Analysis
Our scientific team reviews your protocol, designs the optimal comparator sourcing strategy tailored to your study design. You get a comprehensive clinical trial supply solution, not a price list.
02
Availability
We review all the optimal sourcing markets, batch availability, shelf life and pricing across a network of more than 200 audited manufacturers and suppliers, and remove any option where continuity is at risk.
03
Sourcing and authentication
The product is purchased with consideration of multiple factors (the number of supply runs required based on the shelf life of the product and length of your study, supply per arm and per visit schedule). These are purchased either manufacturer-direct or through the open market. Every unit is quality-checked at purchase and when it enters our depots.
04
QP release and documentation
CSI can provide Statement of Authenticity (SoAs), Certificate of Analysis (CoA) (product priced accordingly), and in some cases, BSE/TSE statements, equivalency statements, certificate of compliance, and batch-release certificate, upon request. For a fee, CSI can also provide a Certificate of Origin (CoO).
05
Cold chain delivery
CSI can handle all temperature-controlled logistics requirements, with continuous temperature monitoring and GDP-compliant handling across 61 countries on six continents.
06
Resupply and forecasting
Rolling demand forecasts, shelf-life control and batch reservation for the life of the study, with one project manager accountable from first shipment to reconciliation.

COLD CHAIN
CSI supports all temperature requirements
GLP-1 pens ship at 2 to 8°C, but a comparator programme rarely ships one product alone. CSI validates the full range so combination and concomitant supply moves together.

Why sponsors choose CSI
150+ years of clinical trial supply experience and a scientific team that reads the protocol before it quotes.
Over 1,200 clinical trials supported
Direct relationships with 200+ manufacturers
Dedicated scientific project management team
Expertise in oncology, biosimilars, immunology and ophthalmology
Access to 15,000+ medicines
Warehousing and distribution across 61 countries
GDP-compliant cold chain at every temperature
Full regulatory documentation with every shipment
Documentation
CoAs can be supplied upon request, in the language your regulatory submission requires. Products supplied with a CoA may be subject to higher costs.
Formal confirmation that the batch was released for supply in its licensed source market under the manufacturer's quality system. Upon request, this can be supplied alongside the Certificate of Analysis, so your QP can trace release back to the licensed market.
A signed declaration that the product is genuine and was acquired through the licensed supply chain. This is the assurance against falsified or diverted product when a comparator is bought on the open market.
Monitoring data for every shipment, reported and assessed for impact on product quality. You receive the record whether or not an excursion occurs.
CASE STUDY
Global Comparator Sourcing of Ozempic® (Semaglutide) for a Phase III Clinical Trial
How CSI delivered mission impossible: sourcing specific tested batches of an expensive oncology product from several European markets.
Challenge
Global Phase III trial needed semaglutide comparators across multiple regions, with single-batch consistency, CoAs, and strict regulatory compliance
Solution
CSI used direct manufacturer access, managed region-specific approvals and CoAs, and ran temperature-controlled, tracked logistics with contingency supply
Result
Comparator delivered to all sites; reduced lead times, consistent quality, and no supply interruptions to the study

FAQ
GLP-1 medicines sourcing, answered
Which GLP-1 comparators can CSI supply?
CSI sources GLP-1 receptor agonists including Ozempic® and Wegovy® (semaglutide) and Mounjaro® (tirzepatide) for obesity, type 2 diabetes and cardiometabolic studies, across Europe, North America, Latin America and Asia-Pacific.
Which presentations are available?
Presentations vary by source market and are confirmed against your protocol before quotation. Price, expiry and availability are confirmed prior to the receipt of a Purchase Order.
How long does GLP-1 comparator sourcing take?
Every study is different, and sourcing timelines depend on your specific requirements, market, quantity and documentation needs. Send us your study requirements and product details, and we will assess what is possible for your programme. Where a study is at risk, CSI has compressed sourcing timelines by working directly with manufacturers. Forecasting matters more than usual here, because market demand for GLP-1 medicines is persistently tight.
What documentation is supplied with the product?
The availability of supporting documentation depends on the country from which the product is sourced and the specific requirements of the study. Where available, CSI can provide documentation such as Certificates of Analysis and country-specific regulatory documentation at an additional cost.
How is cold chain managed for GLP-1 comparators?
Semaglutide and tirzepatide is shipped at 2-8 °C with continuous temperature monitoring, through GDP-compliant depots in 61 countries. CSI also manages -20 °C and -80 °C requirements for other components of your study.
Send us the protocol, the markets and the timeline. Our scientific team will come back with a sourcing strategy for your GLP-1 agonists requirements.
