Warning letters, raids, shutdowns, BBB actions — cited or omitted

FDA issued a warning letter to Peptide Sciences for making health claims about BPC-157 and TB-500 on their website, marketing those research chemicals with references to 'healing' and 'recovery' in a manner that crossed into unlawful drug promotion. No FDA.gov URL for this letter has been independently confirmed; fda.gov warning-letter search returned no direct result for 'Peptide Sciences'.

2023 · fda warning · pepexaminer.com

Peptide Sciences voluntarily shut down all operations on March 6, 2026. The company posted a brief notice stating 'After careful consideration, Peptide Sciences has made the decision to voluntarily shut down operations and discontinue the sale of our research products.' No direct FDA enforcement action against Peptide Sciences was publicly confirmed; shutdown is attributed to escalating industry-wide regulatory pressure (FDA warning letters to competitors Dec 2024, DOJ criminal cases, proposed SAFE Drugs Act) combined with serious product-quality failures identified in independent Finnrick Analytics testing (e.g., E-grade for Retatrutide and CJC-1295).

Cross-vendor price ranking is intentionally not computed

The Trust Index rates each vendor against a fixed evidence rubric — it never ranks vendors against each otheror sorts the directory. Naming a “best-value” vendor per compound would require exactly that cross-vendor sort, so we don’t. Compare the cited price-per-mg in the Products & price table yourself, or open a side-by-side comparison.
