Description
What it is
Tirz is a synthetic, multiply-modified acylated research peptide supplied as a lyophilised powder for laboratory use. Its chemistry includes non-coded amino-acid substitutions that improve resistance to enzymatic breakdown, an amidated C-terminus, and a long-chain fatty-diacid modification that promotes reversible binding to serum albumin. Typically supplied as the acetate salt. This listing describes a chemical reagent only, with no reference to any medicine, indication or effect.
Research context
Tirz is stocked as a reference-grade peptide for in-vitro characterisation and analytical method development by qualified laboratory professionals. As a large acylated peptide it can be confused with related sequences, so mass-spectrometry identity, rather than purity alone, is the reliable discriminator.
2359 studies indexed on PubMed (NIH) for Tirz as of August 2026. A measure of research volume only, not a claim of efficacy.
Handling and storage
Supplied lyophilised in a sealed vial. For laboratory handling the powder is reconstituted with bacteriostatic or sterile water; this is a handling note, not a dose. Store the lyophilised powder cold and protected from light, avoid repeated freeze-thaw, and treat any reconstituted material as cold-chain dependent and short-lived.
Testing and quality
Every batch is third-party tested. The certificate of analysis states the salt form, reports HPLC purity with chromatogram and confirms identity by mass spectrometry, expected versus observed mass. Supplied for laboratory research use only. Not for human or animal consumption.
