editorial standards

this page documents how pur path project sources and tests the materials it supplies, and how the writing on this site is produced and reviewed. it exists so a researcher can evaluate our standards directly, rather than take them on faith.

what we are, and what we are not

pur path project supplies research-grade compounds for in vitro laboratory research use only. we are not a pharmacy, a clinic, or a source of medical, therapeutic, or dosing guidance. nothing we publish is a claim that any compound diagnoses, treats, cures, or prevents any condition, and nothing here is intended for human or animal use.

sourcing

we source research compounds from contract manufacturers; we do not synthesize them in house. we document provenance and trace each unit to a specific production lot, so the physical material ties to its paperwork.

independent testing and documentation

identity and purity are verified by an independent, third-party laboratory before a lot is released for sale. we prioritize independent, accredited (ISO/IEC 17025) testing, so that results reflect an externally assessed laboratory rather than a self-asserted figure. every batch is documented with a certificate of analysis tied to that specific lot, and that certificate is made available so it can be verified before purchase. depending on the material, a certificate can address identity, purity, and net peptide content, and, where appropriate, endotoxin, sterility, and elemental impurities. our articles explain what each of these tests measures and how to read them.

how our writing is produced

our articles are editorial, not advertising, and they follow a fixed discipline:

• we describe what published research and recognized standards say. we do not recommend that anyone use any compound for anything.
• scientific and technical claims are supported by citations to primary literature or recognized standards, for example United States Pharmacopeia chapters, ICH guidelines, and peer-reviewed sources.
• we do not publish usage guidance, preparation-for-use instructions, or dosing of any kind.
• content is reviewed for compliance before publication, and articles are attributed to the pur path project editorial team rather than to invented personas or credentials.
• if we get something wrong, we correct it and note the correction.

research use only

access to our catalog requires account creation and age verification, and everything we supply is for in vitro laboratory research use only, not for human or animal use. pur path project makes no therapeutic, medical, or performance claims of any kind. this posture is consistent across the site, our packaging, and our communications.
