Shop by category
Categories group materials by the pathway they are studied under in the published literature. They are not a statement of effect. Every listing on this site is supplied for laboratory research use only.
BPC-157, TB-500, GHK-Cu, KPV and the KLOW blend, catalogued for laboratory work on tissue response and matrix remodelling.
Semax, Selank, Dihexa and P21, grouped as reference materials for neurobiology and CNS pathway research.
Tesamorelin, Ipamorelin, CJC-1295 and Sermorelin, catalogued for in vitro endocrine and secretagogue research.
NAD+, Epitalon, SS-31 and Glutathione, grouped under cellular, mitochondrial and senescence pathway research.
MOTS-c, 5-Amino-1MQ and AOD-9604, catalogued for laboratory work on metabolic and mitochondrial signalling.
GHK-Cu, Snap-8, Argireline and Matrixyl, grouped under dermal and extracellular matrix research.
KPV, LL-37, Thymosin Alpha-1 and VIP, catalogued for in vitro immune and microbiome pathway research.
Bacteriostatic water, vial racks and cryogenic labels. The consumables a bench needs alongside the catalog.
Why Imperial Biolab
Nothing is listed on the strength of a supplier’s word. A batch is tested by an independent laboratory, documented against its own number, and only then does it reach the catalog.
Every batch is sent to an accredited third party laboratory in the US. We do not report on our own material.
The certificate of analysis for your batch is open on this site before you order, and travels with the shipment.
Product, batch, certificate, stock and order stay linked, and the QR code on every label opens that batch’s certificate.
Kept refrigerated until dispatch, packed discreetly, tracked to the door. We ship within the United States only.
Featured peptides
Eight of the compounds our customers order most. Every vial leaves with its batch number on the label, so the material on your bench can be matched back to its certificate of analysis.

Certificate of Analysis (COA)
Scan the QR code on any Imperial Biolab vial to visit our COA library, then search the batch number on your label to view its Certificate of Analysis: independent test results, the testing laboratory, batch details and the signed report.
Scan the QR code on the label to open the testing for the batch that filled that vial, not a range of batches.
Read the laboratory’s own signed report, not a summary written by us or one certificate reused across several batches.
Product, batch number, test date, laboratory, results and current batch status, without digging through documents.
The COA stays live after the batch sells out, so the record is there whenever you need to check it again.

Method notes, documentation explainers and handling guidance, written by the people who read the certificates.
Most research peptides are made by solid-phase peptide synthesis, which builds the chain one amino acid at a time on a resin bead. Any step that does not go to [...]

Peptides break down through a short list of known chemical routes: oxidation of methionine, cysteine and tryptophan, deamidation of asparagine and glutamine, cleavage of the peptide backbone, cyclization at the [...]

Net peptide content is the share of a lyophilized powder’s weight that is the peptide itself. The rest is mostly counterions held by charged residues, residual water and small amounts [...]

A lyophilized peptide keeps best sealed, dry, dark and cold. Water and heat drive most of the chemistry that degrades a peptide, and freeze drying has already removed most of [...]

A certificate of analysis answers four questions in a fixed order: which batch was tested, whether it is the right molecule, how much of the detected material is that molecule, [...]

Ordering, testing and handling. Everything a qualified researcher asks before placing a first order.
Everything here is supplied for in vitro laboratory research by qualified people only. It is not for human or veterinary use, is not a drug, supplement or food, and has not been evaluated by the FDA.
Qualified researchers aged 21 or over, or buyers acting for a research institution, laboratory or business. We may ask for organization details before releasing a first order.
Every batch is tested by an accredited third party lab using RP-HPLC with LC-MS identity confirmation, to a 99% or higher specification. Results are on that batch’s COA, matched to the batch number on your vial.
All 50 states from our US facility, with no customs or import duty. Orders placed before 2pm Eastern on a business day ship the same day, and tracked shipping is free over $200.
