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.
The number everyone argues about may not be a number Men on hormone protocols spend a lot of energy on one line of the panel. Estradiol. It gets screenshotted, compared, tracked week over week, and treated as the single……
Read full dispatch →Most men handed a testosterone prescription never get asked why their level dropped in the first place. In a large share of cases the answer is metabolic, not testicular — and treating the hormone without treating the…
Read full dispatch →The circular logic problem hiding in your liver panel Every reference range on your blood test was built the same way: a lab draws blood from a large group of "apparently healthy" people, plots the results, and calls…
Read full dispatch →Most of a standard lipid panel takes some explaining. HDL does not. It is the one line almost everyone believes they already understand: HDL is the good cholesterol, it carries plaque away from the arteries, and a high…
Read full dispatch →Hemoglobin A1c may be the most trusted number in metabolic medicine. It anchors the diagnosis of diabetes, it defines prediabetes, and for most people it is the only glucose-related marker their annual physical ever…
Read full dispatch →Most of the markers worth writing about follow the same shape. Low is bad, high is bad, or the risk climbs steadily in one direction and the only question is where the useful threshold sits. You can hold one idea in…
Read full dispatch →Almost every blood panel drawn in the United States includes a complete blood count, and almost every complete blood count reports a value called RDW, or red cell distribution width. It sits in the middle of the…
Read full dispatch →An FDA advisory committee spent two days in late July 2026 voting on whether seven peptides should be added to the list of substances that compounding pharmacies are permitted to work with. Six of the seven got a…
Read full dispatch →There is a specific and very common clinical situation that goes something like this. A man in his late forties reports low energy, flat mood, poor recovery from training, and a body composition that has been drifting…
Read full dispatch →Almost every blood panel run in the United States reports a number called eGFR, the estimated glomerular filtration rate. It is the standard measure of kidney function, it comes back as a tidy two-digit figure, and it…
Read full dispatch →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…
Read full dispatch →You can run a full lipid panel, watch your LDL and triglycerides land in range, and still be walking around with a fatty-acid profile that quietly tracks with a shorter life. Standard cholesterol testing measures how…
Read full dispatch →Two people walk into the same clinic. Same age, same LDL cholesterol, same blood pressure, same clean stress test. On paper their cardiovascular risk looks identical. Over the next decade, one of them has a heart attack……
Read full dispatch →Here is an uncomfortable fact about the standard cardiovascular workup most adults receive: it can come back clean — total cholesterol fine, LDL fine, blood pressure fine — while missing a risk factor that roughly one…
Read full dispatch →The marker that fails first — and gets tested last There is a specific sequence to how metabolic disease unfolds, and almost nobody gets to watch it happen. By the time the standard markers move, the disease is years…
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…
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…
Read full dispatch →The marker your annual physical almost never orders Walk into a routine physical in the United States and ask for a "complete iron panel." Most primary care providers won't order one unless you're female, pregnant, or…
Read full dispatch →Your last physical reported 25-hydroxyvitamin D at 32 ng/mL. The lab range said 30-100. The note from your physician said "sufficient." That note is the problem. Because while your D level cleared the bar designed in…
Read full dispatch →The marker hiding in plain sight If you are over 40 and you have ever asked your physician for a "complete" blood panel, take a second to find your most recent lab report. Look for one word: homocysteine. Most readers…
