Sterile Is Not Safe: What the August Endotoxin Recall Reveals About Injectable Peptide Quality

A licensed compounding pharmacy recalled three lots of an injectable peptide product on August 5 after its own testing found elevated bacterial endotoxin. The vials were almost certainly sterile. Here is why those two facts coexist, and what your Certificate of Analysis needs to say about endotoxin.

The Verdict Is In: 70 Months in Federal Prison for Forged Peptide Testing

A landmark federal prosecution exposes the dangers of forged Certificates of Analysis in the research peptide market. What the 70-month prison sentence means for the industry and why independent testing is the only path forward.

The Identity Problem: What IS BPC-157?

The FDA's advisory panel voted to recommend BPC-157 for compounding. But their own scientists raised a question that matters more than the vote itself: What IS BPC-157?

The Oral Peptide Breakthrough: What Enlicitide Teaches Us About Testing

FDA’s approval of enlicitide, the first oral PCSK9 inhibitor, shows why macrocyclic peptide structure, formulation, and fit-for-purpose analytical testing must be interpreted as one connected system.

Same Name, Different Chemical: The Hidden Salt-Form Trap in Peptide Testing

FDA’s July 2026 peptide briefing documents expose a critical testing issue: a common peptide name may not identify its salt form, assay basis, or true peptide content.
