Deep dives into peptide science — evidence-graded, honestly reported
RFK said peptides are back. The FDA hasn't published the rule change yet. Here's what's actually happening.
The FDA's 2026 peptide reclassification is a regulatory process, not a completed rule change. Seven compounds face PCAC review in July 2026, legal access requires a prescription, and the grey market remains unchanged until the FDA publishes.
Detailed compound profiles with mechanisms, safety data, and dosing protocols
A synthetic heptapeptide that acts as a molecular GPS for your body's repair crew — directing cell migration, building new blood vessels into injured tissue, and potentially re-activating embryonic healing pathways.
TB-500 is the synthetic analog of Thymosin Beta-4, a naturally occurring protein involved in actin regulation, cell migration, and tissue repair. Its unique mechanism targets the body's internal repair logistics rather than just providing raw materials.
