Editorial correspondence

Sigma A Peptides welcomes correspondence on the research record: a citation we have quoted inaccurately, a regulatory reference that has gone out of date, or a peer-reviewed study about Selank or Semax that should be added to the references page. Given that both compounds have a predominantly Russian literature — with many key papers in Russian-language journals and English abstracts only — corrections that improve the accuracy or breadth of the citation record are especially useful, and they are read carefully.

The most actionable notes specify three things: the page they refer to, the exact passage in question, and the supporting citation — a DOI or PubMed ID wherever possible. That lets us verify a proposed change against the source quickly.

What this desk cannot do

So that no message goes unanswered for the wrong reason, a few things fall outside what this site can address. Sigma A Peptides is a literature digest, not a clinic or a vendor, so we cannot:

• Advise on, recommend, or comment on human use of Selank, Semax, or any other peptide.
• Suggest a dose, schedule, or route of administration for any individual.
• Diagnose a condition or judge whether a particular research finding applies to a particular person — including anxiety, cognitive decline, or any other condition discussed in the underlying research.
• Sell, source, recommend, or help locate any compound from any supplier.
• Answer requests from athletes subject to anti-doping rules about using these compounds.

Readers seeking guidance on anxiety, cognition, or any other medical matter should consult a licensed clinician in their own jurisdiction. Responses to editorial correspondence are not guaranteed and may be delayed; the mailbox is monitored intermittently.
