What we supply
Everything a biosimilar programme needs to compare against the reference product, in one enquiry.
Whole-pack originator products
Reference products from the originator manufacturers, supplied as complete packs rather than split into aliquots. Browse the full range and tell us what you need.
View all moleculesBiosimilar comparators
Approved biosimilars listed alongside their reference product, so a study can include both sides of the comparison from a single source.
View biosimilarsSeveral batches, several countries
Comparability work usually needs more than one lot. We source multiple batches of the same product from different countries and tell you where each one comes from.
How it worksAnalytical testing
Characterisation work such as glycan profiling, deamidation and oxidation analysis, delivered through our laboratory partner.
Analytical servicesBuilt around the comparator brief
We work with teams developing biosimilars. These are the numbers behind the catalogue.
Why teams use comparator sourcing
Four things a comparability study depends on, and how we handle each.
01 Reference products, whole packs
Packs are supplied as the manufacturer made them. No splitting, no repackaging, no loss of traceability to the original presentation.
View details02 Multiple batches per product
Similarity studies compare lots, not single vials. Ask for the number of batches you need and we source accordingly.
03 Different countries of origin
Where the same product is marketed in several countries, we can source from more than one so the comparison covers real supply variation.
04 Clear batch and origin information
You are told which batch and which country each pack comes from before you commit, so your study records are complete.

Frequently asked questions
Short answers to the things buyers ask most often.
Why are prices not listed?
Price and availability depend on the product, batch and country of origin, so we quote each request individually. Send an enquiry and we will respond with both.
Do you split products into aliquots?
No. We supply whole packs as the manufacturer produced them.
Can I ask for several batches of one product?
Yes. Say how many batches you need and, if you want, which countries they should come from.
Who do you supply?
Businesses and professional teams, mainly biosimilar developers and their research partners. We do not supply individuals.
Can you also test the product?
Yes. Analytical services such as glycan profiling and oxidation or deamidation analysis are available through our laboratory partner.
