Third-party tested
Every lot is analyzed by an independent ISO/IEC 17025 accredited laboratory.
Identity, purity, documentation, and batch traceability — the standards behind every lot.

Why Prime Labs
Trust is earned through evidence, not adjectives. We publish the batch data, name the testing laboratory, and let researchers verify every claim independently.
COA for every batch
Identity, purity, and date tested are recorded on each lot certificate. Use the batch number to access the matching analytical record.
Batch traceability
Each vial is tied to a production lot so researchers can request the matching analytical record.
Cold-chain fulfillment
Temperature-controlled packaging and tracked shipping to U.S. laboratories.
Research use only
Supplied as laboratory reagents. Not for human or veterinary use.
Documentation support
Our team answers COA, specification and procurement questions directly.
Featured peptides
View allQuality standards
Molecular identity
Confirmed by mass spectrometry against the expected molecular weight.
Purity
Determined by reverse-phase HPLC with UV detection at 214 nm.
Complete analytical records
Documented for identity, purity, water content and residual acetate.
Cold chain packaging
Lyophilized material is sealed under inert atmosphere and shipped in insulated packaging.
Quality process
From manufacturing to your laboratory
Step 1 of 4
Manufacturing
Unique batch numbers link every vial to its specific analytical results and production record.
Verified researcher feedback
About fulfillment, packaging, and documentation — not experimental outcomes.
“Tracking posted the same day the order left the facility. Straightforward for a laboratory purchasing workflow.”
“Cold-chain packaging arrived intact and the gel packs were still solid. The batch number on the vial matched the paperwork.”
“The COA request came back with lot-specific HPLC data. That level of documentation is what we require before receiving reagents.”

Lyophilization, storage, and handling
Why research peptides ship as lyophilized solids, how cold storage and freeze–thaw cycles affect solutions, and how to do reconstitution arithmetic without turning a catalog into a clinical protocol.
Read article →How to read a Certificate of Analysis
A COA is only evidence if the batch numbers match, the laboratory is independent, and identity plus purity methods are present. This is a reading guide — not a downloadable stock PDF.

How reverse-phase HPLC reports chromatographic purity, why 214 nm is used for peptides, and how mass spectrometry confirms that the main peak is the intended sequence.
