Stop Guessing About Purity.

Tirzepatide is best known for its glucose- and weight-lowering effects, but a newly published study adds evidence for another benefit: a real reduction in serious cardiovascular events. Published in The British Medical Journal, it's one of the largest real-world looks yet at how tirzepatide performs on cardiovascular outcomes outside a clinical trial setting.

Peptides are prized for their ability to drive specific biological processes like bone formation and tissue repair, but their small size has always worked against them in drug delivery: once placed in water-rich materials like hydrogels, they tend to diffuse away long before healing is complete. A new Rice University study, published in Cell Biomaterials, offers a surprisingly simple fix.

Harvard Health Publishing recently examined the fast-growing world of injectable peptides, from FDA-approved medications like insulin and GLP-1 drugs to the unregulated compounds sold online for research and personal use. Their findings offer a useful checkpoint for anyone following the peptide space, including everyone in our own research community.

A new nonprofit is building the first peptide-specific accreditation standards for compounding and sourcing, just as regulators weigh whether to expand access to several popular research peptides.

The FDA advisory panel's vote to ease restrictions on six peptides made headlines this week. But the vote wasn't as clear-cut as the headlines suggest. Behind the scenes, FDA's own scientific staff recommended against it, several panel members have documented industry ties, and the peptides in question are already circulating on the unregulated gray market. Here's what the coverage is missing.

Last month's FDA advisory panel vote on peptide compounding made headlines everywhere — but it's created almost as much confusion as clarity. Here's what actually changed, what hasn't, and what to expect next.

With regulatory attention on peptide purity and sourcing higher than ever, knowing how to evaluate a supplier yourself is one of the most useful skills a researcher can have. Here are five warning signs that should make you think twice before ordering.

A look at the FDA's July 2026 compounding-committee vote on six popular peptides, the safety concerns it has raised among the agency's own scientists and patient-safety groups, and why verified, lab-tested sourcing still matters most.

Many research protocols call for combining more than one peptide at a time, but stacking introduces its own set of variables beyond what a single-compound study requires. This guide covers the basics of peptide stacking: why researchers combine compounds, how to think about complementary mechanisms, timing and injection site considerations when multiple peptides are in use, and the documentation habits that keep a multi-compound protocol interpretable.
