Made with precision.
Documented with clarity.

Every product in the catalog is defined by three attributes: compound name, stated quantity per vial and form. Names and strengths are listed exactly as supplied, with common synonyms shown alongside so the same molecule is not mistaken for something else.

On the vial, identity is carried by a consistent label system: monogram, product name, strength, a research-use band and dedicated batch and expiry fields.

Purity is a measured result, so we treat it as a property of a batch rather than of a product. Analytical information such as identity by mass spectrometry and chromatographic purity by HPLC is reported only from issued documentation for a specific batch.

We do not display generic purity figures across a product line. Where a batch has no published analysis, we say so.

Each label carries a batch number and an expiry date. The batch number keys a record that holds the product, the manufacturing and expiry dates and the documentation status for that lot.

Those records can be checked publicly through Batch Verification as they are published.

Certificates of analysis are linked from batch records when they exist. A COA describes one batch only, so it is always presented next to the batch number it belongs to.

Documentation for any product can be requested as part of a B2B inquiry.

Storage conditions are stated with each batch's documentation, and that documentation takes precedence. As general practice, lyophilised research peptides are held cold, dry and protected from light.

Our research note on lyophilisation explains the factors that matter.

T-PEPTIDES operates a professional B2B supply model. Every order begins as an inquiry, is reviewed by our team and is confirmed directly with the client: availability, quantities, documentation and logistics.

Handling and transport conditions for volume orders are confirmed as part of the quotation.
