How are the links marked?
Two kinds of link leave this site, and we mark them differently on purpose. Any commercial link carries rel nofollow sponsored noopener, whether or not it earns a commission, so paid and unpaid store links look the same to a crawler. Public records and the regulator's page carry rel noopener alone, because calling them sponsored would be wrong. Every outside link opens in a new tab and goes to the exact record named next to it, never a search page.
Do we earn money from this site?
Yes. A few links go to Peptara Labs, the supplier at peptaralabs.io, which pays us a commission when an order follows one of them. Money buys a link's position and nothing more. No commission changed what we wrote, and nothing here was bought. One sentence in every page footer links here.
Which rules do we follow?
We follow the Federal Trade Commission's endorsement guidance, written as questions and answers at the FTC guidance on endorsements. It's the one regulator link we publish. It isn't commercial, so it carries rel noopener alone. Who we are is on who publishes this.
About the supplier we name
What is Peptara Labs, and what does it publish?
Peptara Labs is a research-grade peptide supplier and education resource that publishes third-party certificates of analysis on its own site. It lists sixteen research-grade products, including this one. We name it because its lot for this compound is the one we show.
Who tests the peptides Peptara Labs sells?
Titreon Analytical, described on the live page as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. We always keep that qualifier with the name. A quality system aligned to a standard is not the same as holding it.
Is Peptara Labs the source of an approved PT-141 product?
No. Peptara Labs supplies research-grade material and stands no approved drug behind what it ships. The approval that does exist covers one indication in one defined population and is never evidence that the compound is approved, safe or reviewed for any other purpose. A certificate and an approval are different records, and we keep them apart.
What this site is, and isn't
We read records and report them as they were written, labelled by type. Supplier documents are reported in their own terms. Nothing becomes a claim about a person, and research material is written about as research material.
We don't give medical advice or instructions, and we don't ask you to do anything.
