Curated peptide research dispatches, clinical trial coverage, regulatory updates, and evidence-based summaries from the broader peptide science literature. The Dispatch tracks GLP-1 receptor agonists, BPC-157, growth hormone secretagogues, and other emerging compounds.
There is a specific failure mode in lab testing that is worth understanding, because it repeats across several nutrients and magnesium is its cleanest example. The failure is this: the test that gets ordered measures the…

Read full dispatch →Most people get a comprehensive metabolic panel once a year. Most of those panels include something called GGT, or gamma-glutamyl transferase. Most patients have never heard of it. Most doctors glance at it, see a number…
Read full dispatch →You ran an annual physical. Your CBC and CMP came back. Buried in the metabolic panel, in a row most patients never read and most physicians never circle, sits a number called **uric acid**. Yours is 6.8 mg/dL. The lab …
