What This Means for Researchers
The vendors shutting down are primarily those that made therapeutic claims, sold compounds with human-use implications, or operated without compliance infrastructure. Vendors that maintain strict RUO labeling, third-party testing, and transparent operations continue to operate. See our Compliance Policy for how Pepta Labs is structured.
