Research Peptides & Reference Materials
Every lot of every peptide we supply carries its own certificate of analysis — purity by RP-HPLC, identity by mass spectrometry, retrievable by lot number before you order.
49 research compounds · 12 mechanism-class collections · certificate of analysis per lot
The method and the threshold are published, per item. We would rather show the procedure than assert a result.
A stated purity floor for every compound, with the method named — ≥98.0% by RP-HPLC for peptides. Never a bare “high purity.”
Each production lot has its own certificate of analysis, retrievable by lot number without an account. No document yet? The page says so.
Purity by reverse-phase HPLC and identity by mass spectrometry, reported per lot by an independent contract laboratory.
Lyophilized material ships in plain, insulated packaging with a phase-change pack. Transit temperature is not monitored.
Verification
Most suppliers make the same three claims — high purity, third-party tested, made in the USA — and none of them can be checked at the moment of purchase. Our position is narrower and checkable: the evidence is named, per-lot, and findable in seconds.
Retrieve the certificate for the exact vial you are holding by entering its lot number. No account, no email gate. Where a lot’s results have not yet published, the certificate field shows its designed pending state — the specification never stands in for a measurement.
How purity reads on this site
The specification is the standing commitment we make; the lot value is a measurement an instrument produced. Shown side by side — never merged, never rounded.
A cross-section of the compounds researchers ask for most often. Each links to a full specification and its lot documentation.
Peptide
A synthetic peptide of fifteen building blocks (a pentadecapeptide), based on a partial sequence of a protein first identified in gastric juice.
Peptide
A short peptide of seven amino acids corresponding to a fragment of the protein thymosin β4. A crystalline solid, supplied as a single-lot reference material.
Peptide
A synthetic 31-amino-acid research peptide in the GLP-1 receptor agonist class. A crystalline solid, supplied as a single-lot reference material.
Peptide
A synthetic 39-amino-acid research peptide in the GIP/GLP-1 dual-agonist class — a two-target incretin compound. A solid, supplied as a single-lot reference material.
Peptide
A synthetic five-building-block peptide (a pentapeptide) in the growth-hormone-secretagogue class — smaller than its six-block cousins, and heavily engineered.
Peptide
The copper-bound form of the tripeptide GHK: a single copper atom held by a three-building-block peptide, and a familiar small peptide in research.
Peptide
A synthetic tetrapeptide of just four building blocks, as a crystalline solid. Best verified by identity, since its name is shared with a different substance.
Peptide
A synthetic 16-amino-acid peptide, unusual for being encoded within mitochondrial DNA rather than the nucleus. Supplied as a single-lot reference material.
Compounds are grouped by the receptor or pathway they act on — mechanism class, never an intended outcome.
Peptide
A synthetic research peptide in the incretin family, one of the multi-target (GLP-1/glucagon dual) compounds. Supplied as a single-lot reference material.
Peptide
A synthetic 39-amino-acid research peptide in the incretin family — one of the newer multi-target compounds. Supplied as a single-lot reference material.
Peptide
A larger peptide of thirty-seven building blocks, in the amylin-analogue class, carrying a fatty-acid tail attached to its chain.
Peptide
A synthetic 34-amino-acid research peptide, one of the multi-target compounds in the incretin family. Supplied as a single-lot reference material.
