Quality

Quality you can verify.

Limited runs, per-batch analysis, cold-chain from lyophilisation to your door. Every claim on this page has a matching artefact in the parcel.

QC Specification

Five tests, every batch.

These are the exact tests on every COA. If a batch misses a threshold, it does not ship — it is re-produced or rejected.

Test Method Acceptance
Purity Reversed-phase HPLC (UV 214 nm) ≥ 99.0 %
Identity / mass ESI-MS (positive ion) Observed m/z within ± 0.5 of theoretical
Peptide content AAA / UV correction ≥ 80 % net peptide
Water content Karl Fischer titration ≤ 5 %
Endotoxin LAL (gel-clot or kinetic) < 1.0 EU/mg (research-use spec)

Values are typical research-grade targets. Individual COAs may exceed these specifications — the signed COA that ships with your batch is the authoritative reference.

Four Pillars

How we hold the line.

Sourcing discipline

Every compound comes from a shortlist of manufacturers we work with repeatedly. No opportunistic sourcing, no cheapest-available pipelines, no broker chains of unknown provenance.

Batch analysis

Third-party analysis before a batch enters inventory or leaves QC for a fresh-batch order. The COA is not marketing — it is the stop-gate.

Cold-chain & storage

Lyophilised at source, stored at ≤ −20 °C, shipped with phase-change cold packs in insulated boxes. A cold-chain break compromises the research, not just the product.

Catalog restraint

48 compounds, 97 variants. The number is deliberate. Fewer SKUs means tighter oversight per batch. Growth by volume is not the goal — consistency is.

Verify Yourself

COA in every parcel, plus an email copy.

Every order dispatches with a printed Certificate of Analysis matched to the batch ID on your vial label. A digital copy arrives by email at dispatch time. Lost it? Send us your order reference — we retrieve the archived COA on request.

Research-Use Positioning

One more thing.

Every compound on this site is presented strictly for laboratory research. Quality standards exist to serve research integrity — they are not a medical claim, a therapeutic guarantee, or human-use approval. No compound should be used outside a controlled research setting.
