Plain-language, citation-backed notes on research peptides: what the preclinical and clinical literature actually shows, how compounds are verified, and how to read the data for yourself. Written for qualified researchers; nothing here is medical advice.

Four warning letters dated August 24, 2026 spell out when FDA treats a research-use-only peptide as an unapproved drug. The label is not the test.
Between May and August 2026, four independent reviews mapped the evidence for BPC-157, thymosin beta-4/TB-500 and GHK-Cu. Their shared verdict is worth reading.
An FDA advisory committee recommended six peptides for the 503A compounding list in July 2026. Here is what a non-binding vote does, and does not, mean.
An NR pilot in mild cognitive impairment doubled blood NAD+ without improving cognition; an oral NAD+ formulation raised intracellular NAD+ in six days.
A 32-rat study compared BPC-157, TB-500 and their combination after Achilles transection. TB-500 led on biomechanics; the combination was not additive.
ADA 2026 delivered phase 3 data on a triple GLP-1/GIP/glucagon agonist, a dual agonist, CagriSema and two oral agents. Here is the map.
One June 2026 MOTS-c study found reduced cardiac inflammasome activity in diabetic rats; another found it impaired repair by human stromal cells.
In 2026 FDA moved to end bulk compounding of GLP-1 drugs and began citing research-labeled sellers of the same peptides. The two stories are one story.
Three decades of rodent studies, a handful of mechanistic papers, and no published human trial. A plain-language map of the BPC-157 literature.
A plain-language primer on what peptides are, how they are built from amino acids, and why short chains of residues occupy so much of modern research.
How a single peptide came to activate three proglucagon-family receptors, what phase 2 trials of the class reported, and what is still unknown.
Identity, purity, quantity and the lab that signed it — the four sections of a COA that matter, and the red flags that mean it certifies nothing.
Sermorelin is the first 29 amino acids of human GHRH. What the pediatric, aging and mechanistic literature actually recorded, and where the evidence stops.

The research notes explain what HPLC and mass-spec results mean. The COA library shows you the actual documents for the material Wednesday carries.
