Trump Taps Dr. Heidi Overton to Lead the FDA — What It Could Mean for Peptide Regulation

Australian doctors are investigating a seventh case of acute liver toxicity linked to black-market peptides sold as retatrutide. Here's what the cluster reveals about counterfeit contamination and why batch-specific testing isn't optional.

A reconstituted FDA advisory panel just overruled its own career scientists to back six peptides for compounding. Here's what actually changed, what didn't, and why verified sourcing still matters most.

Delta sleep-inducing peptide, or DSIP, has become one of the more talked-about compounds in 2026's sleep-and-recovery corner of the peptide world. Interest has outpaced the science, though, and much of what circulates online blurs decades-old animal data with modern marketing claims. Here's a clear look at what DSIP actually is, what the current research does and doesn't support, and why sourcing and purity matter for anyone studying this peptide.

GHK-Cu is a naturally occurring copper-binding tripeptide that has drawn growing interest in dermatology and wound-care research. As demand for peptide-based skin treatments keeps climbing in 2026, it's worth separating what the science actually demonstrates from what's still speculative. Here's a look at what GHK-Cu is, what the current research shows, where the evidence runs out, and why sourcing and purity matter more than ever for anyone studying this compound.

U.S. Customs and Border Protection has flagged a sharp rise in seized peptide shipments moving through international mail facilities and ports of entry in 2026, a trend regulators tie to surging consumer demand for weight-loss and wellness peptides. For the research community, the enforcement data underscores a persistent problem: as demand climbs, so does the incentive to counterfeit. Here's what the seizure trends show, why counterfeits are proliferating, and how legitimate researchers can protect the integrity of their work.

Eli Lilly has filed six lawsuits against wellness and compounding vendors it accuses of selling retatrutide, its unapproved obesity drug candidate, to consumers under the guise of "research use only" peptide sales. Here's what the lawsuits allege and what they signal for the broader research peptide industry.

A major telehealth brand just signaled that peptides are going mainstream. Here's what Hims & Hers' 2026 peptide launch means for the research community and quality-focused buyers.

Peptides are everywhere in wellness culture right now, promoted for everything from muscle building to weight loss to smoother skin. But Stanford Medicine researchers say the excitement has outpaced the evidence. In a recent breakdown of the trend, pathology professors Katrin Svensson and Jonathan Long laid out what's actually known, what isn't, and why the biggest danger for most people isn't the peptide itself. It's where it came from.

When you're purchasing research peptides, one number matters most: purity. But what does "99.1% pure" actually mean? And how do you know a certificate of analysis (COA) is legitimate? In this guide, we'll walk you through peptide quality standards, how purity is measured, and what red flags to watch for when sourcing research-grade compounds.
