Every batch is independently tested by an accredited US laboratory and published with a batch-specific Certificate of Analysis, so you can verify identity and purity before you buy. For research use only.
A research peptide you cannot verify is a research peptide you cannot use. Every batch we receive is sampled and sent to an independent US-based analytical laboratory before any vial is listed for sale. We publish what comes back, unedited.
HPLC
Purity by chromatography
Reverse-phase high-performance liquid chromatography establishes purity against the impurity profile. This is the number on the certificate.
LC–MS
Identity by mass
Mass spectrometry confirms the observed molecular mass matches the expected mass. Purity alone does not tell you what the molecule is.
Karl Fischer
Water content
Residual moisture in a lyophilised powder affects stability and the true peptide mass in the vial. It is measured, not assumed.
Independent
Not our own lab
Testing is commissioned from a third-party laboratory with no stake in the result. We do not run our own assays or select which results to publish.
Featured research peptides
Twenty-five research compounds, supplied as lyophilised powder in 3 mL borosilicate vials and shipped from the United States.
Competitive peptide pricing, without cutting the testing
In this market a low price is usually a warning sign, because it normally means testing was skipped. Ours is structural, and we would rather explain it than have you assume the worst.
No storefront, no middle layer
We run lean deliberately. No retail footprint, no distributor tier taking a cut, and no paid endorsements built into the price of a vial.
Direct sourcing
We buy directly from synthesis partners rather than through resellers, and hold fewer, larger lots instead of many small ones.
The saving is passed on
Analysis is a fixed cost per lot that we treat as non-negotiable. What we save on overhead comes off the price, not off the testing.
Shipping
Dispatched from the US
Orders placed before 2pm CT on a business day are dispatched the same day. Tracking is issued on dispatch.
Handling
Cold-chain packaging
Lyophilised vials ship insulated with cold packs and are stable for the duration of transit. Refrigerate on arrival.
Storage
Lyophilised stability
Sealed lyophilised powder is stored at -20 °C and protected from light. Per-compound conditions are on each product page.
