Research catalog. 99%+ pure. US tested & fulfilled peptides.

Every item listed here is supplied as a reference compound for laboratory research. The catalog is organised by molecular family rather than by application, because a research peptide is defined by what it is — its sequence, its mass, its structural class — and not by any result attributed to it. The buckets above group compounds by that shared chemistry: cytoprotective sequences, growth-hormone secretagogues, mitochondrial-derived peptides, copper-coordinated tripeptides, neuropeptides, senescence and antioxidant compounds, melanocortin-family peptides, and the laboratory solvents supplied alongside them.

Most catalog items ship as a white to off-white lyophilized powder in a sealed borosilicate vial. Lyophilization — freeze-drying under vacuum — removes water without heating the material, which is what allows a peptide to be stored and shipped as a stable solid rather than a solution. The physical form matters for handling: a lyophilized cake dissolves readily in an appropriate solvent, and the vial is sealed under an inert headspace so the powder is not exposed to atmospheric oxygen or moisture before it is opened.

Peptides differ widely in how robust they are. Proline-rich sequences with no cysteine tolerate a broad pH range and resist enzymatic hydrolysis. Sequences containing methionine or tryptophan are oxidation-sensitive, and light and dissolved oxygen drive their dominant degradation pathway. Copper-coordinated compounds carry a visible colour that acts as a direct identity check on the intact complex. These differences are why storage guidance is stated per compound on each product page rather than as one blanket instruction across the catalog.

Identity and purity are established analytically, not asserted. Each lot is characterised by high-performance liquid chromatography for purity and by mass spectrometry for molecular identity, and every lot carries a certificate of analysis issued by an independent third-party laboratory. That certificate is published rather than summarised: the purity figure shown against a product is the exact result for the lot currently shipping, not a category minimum or a marketing rounding. Lot codes are traceable from the vial label through to the certificate, so a specific vial can always be matched to the document that describes it.

Testing, release and fulfillment are carried out in the United States. Vials are held under a controlled cold chain and dispatched with the handling window stated on each product page. Where a compound is supplied as a pre-mixed blend, the certificate covers the blend as shipped, and the component chemistry is documented on the product page for that item.

Nothing in this catalog is a drug, a supplement, a cosmetic or a food. No product listed here is approved by the Food and Drug Administration for any use, and none is intended to diagnose, treat, cure or prevent any condition. All products are sold for laboratory research use only and are not for human or veterinary consumption.
