Reproducible results start with reference material you can verify. We document every step, from synthesis to the vial that reaches your bench.
Independent HPLC and mass-spec analysis confirms identity and purity on every lot before it ships
A lot-specific Certificate of Analysis is linked to each product and downloadable by batch number.
Every vial carries a batch and lot number tied to its testing records, so your data stays auditable.
In-stock orders leave our facility within 24 hours in temperature-stable, plainly labelled packaging.
Catalog
Browse by compound. Each listing offers concentration and multi-pack options, with the lot COA one click away.
Documentation
Every vial is documented from synthesis to your bench. Here is what stands behind the label.
Every batch is verified by HPLC-MS for identity, purity, and consistency before release.
A Certificate of Analysis ships with every lot, keyed to its unique batch number.
Produced in a controlled domestic facility under GMP-aligned, documented processes.
Relied on across labs, clinics, and core facilities for reproducible research outcomes.
Lyophilized, sealed, and shipped in temperature-stable, discreet packaging.
In-stock orders leave our facility within one business day of payment.
Research resources
Practical notes on documentation, handling and quality, written for research buyers. Educational only, never medical advice or usage guidance.
What the retention time, mass confirmation and net peptide content actually tell you about a [...]
Temperature, solvent choice and stability windows that keep your bench data reproducible.
Why purity and identity are two separate questions, and why a supplier should answer both.
Order today, dispatched today
Place your order before 11:00 AM and it leaves the lab the same day. Every compound is backed by a batch Certificate of Analysis — free US shipping over $250.
Questions
Everything qualified researchers ask before ordering. Still unsure? Our team replies within one business day.
Each lot is analysed by an independent laboratory using HPLC and mass spectrometry to confirm identity and purity to a documented 99% standard. Results are published as a lot-specific Certificate of Analysis that you can download by batch number before or after purchase.
In-stock orders placed before 11:00 AM dispatch the same business day; all other in-stock orders leave within 24 hours. Free shipping applies to US orders over $250. Tracking is emailed at dispatch, and packaging is plain and discreet.
Lyophilized peptides are shipped in temperature-stable packaging and should be stored at minus 20 degrees Celsius for long-term stability. Once reconstituted, keep refrigerated and use within the window noted on the product page for best research consistency.
If an independent assay shows a lot below our stated 99% purity, contact us for a full refund or replacement. Unopened, undamaged vials may be returned within 14 days. Opened vials cannot be returned for safety and integrity reasons.
You can check out as a guest, but a free research account unlocks batch COA history, restock alerts, and volume pricing for qualified labs. Account holders also get faster reordering of previously purchased lots.
