The reference source for research peptides.
Research peptides released against an independent laboratory certificate, published for every lot before it is listed and kept at a stable address after it sells out.

03 · Method
How a lot reaches this catalog.
Solid phase, monitored
Fmoc chemistry on 2-chlorotrityl or Rink amide resin. Coupling is monitored stepwise; a failed cycle ends the run rather than getting capped and carried forward.
Fmoc/tBu≥ 99.5% stepwise
Pooled on purity
Preparative RP-HPLC over C18, acetonitrile against 0.1% TFA. Fractions are pooled on purity, not yield - the tail of the peak is discarded even when it would pass.
Prep RP-HPLCAcetate exchange
Someone else’s instrument
Material is sampled and sent to one of three contract laboratories on rotation. We do not run our own release assay, and we do not choose which laboratory sees which lot.
3 labs, rotatedBlind allocation
Sealed, seated, tracked
Vials ship seated in a moulded insert inside a rigid outer, with the packing note carrying every lot number. Lyophilised material is stable at ambient temperature in transit, so no coolant is used.
Moulded insertTracked dispatch
The page never comes down
The certificate goes online the day the lot is released and stays there after it sells out, is superseded, or is withdrawn. Withdrawn lots keep their page and gain a dated note.

A code on every vial
Each vial is printed with a six-digit code under its lot number. It resolves to the certificate for that lot, so the paperwork can be checked against the vial before it is opened.

What a certificate should contain, and usually doesn’t.
Drawn from documentation published by research-chemical suppliers. Compare any of it against what arrives with your current material.

05 · Terms of supply
For laboratory research use only. Not for human consumption.
Material is sold as a laboratory reagent to qualified investigators, institutional laboratories and commercial R&D groups, for in-vitro work and non-human in-vivo studies under an approved protocol.
Read the full policyWhat we will not do
No therapeutic, diagnostic or preventive claims. No dosing guidance, protocols or administration instructions, and no answers to questions about personal use.
Regulatory status
None of these compounds is approved by the FDA for human use, and none is supplied as a drug, food, cosmetic or dietary supplement. Purchasers are responsible for compliance in their own jurisdiction.
If a lot fails after release
The lot is withdrawn, every recipient is notified, and the certificate page gains a dated withdrawal note. Material is replaced or refunded at your choice, including shipping.
