The FDA's proposal to end large-scale compounding of semaglutide has a new comment deadline: July 30, 2026. The direction has not changed. What the docket means if you're on a compounded GLP-1, and how to plan a transition before the rule is final.
A 13,000-patient cohort presented at Heart Rhythm 2026 found GLP-1 medications tied to lower atrial fibrillation risk, even in patients who gained weight. What the finding means, what it does not, and who should keep an eye on heart rhythm during treatment.
For decades, chronic fatigue could only be diagnosed by ruling everything else out. New research on a blood test with 96 percent accuracy is changing that, and it validates every patient who was told their labs look normal.
Testosterone therapy works on a schedule. Libido and energy move first, strength follows, and body composition takes about three months. A 2026 study of 9,537 men mapped the timeline, and follow-up labs at each checkpoint tell you whether your protocol is on track.
Your TSH came back normal, but you're still exhausted, gaining weight, and cold in July. One test can't see a conversion problem, a reverse T3 block, or early Hashimoto's antibodies. The full six-marker panel to ask for, by name.
Cheap semaglutide ads are everywhere, and the FDA keeps sending warning letters to the companies behind them. What the letters say, the red flags to check before buying a GLP-1 online, and how a supervised local program differs.
Medicare now covers certain GLP-1 weight loss medications for a flat $50 monthly copay. Who qualifies, which formulations made the list, the fine print about deductibles and end dates, and the unpublicized pricing condition behind the deal.
The scale stopped moving even though nothing changed. A plateau on a GLP-1 is normal, but it's usually a signal. Here's what a real workup checks: dose, lifestyle, and the biology most programs never test.
Wegovy and Ozempic are both semaglutide. Zepbound and Mounjaro are both tirzepatide. What actually separates the four brand names, what the SURMOUNT-5 head-to-head trial found, and why the program around the prescription matters more than the name on the pen.
Alli has been on pharmacy shelves since 2007. In June 2026 the FDA added a warning for acute kidney injury and kidney stones. What the label change says, who should pay attention, and why supervised weight loss looks different.
Tired in a way sleep does not fix? Hair thinning for no clear reason? Ferritin is the iron-storage marker standard panels routinely skip, and a normal result can still be too low. Here is what it measures, what high and low feel like, and how it is tested.
Testosterone raises the ceiling on what your training and recovery can reach, but your habits decide how close you get. Here is what the research shows about pairing TRT with lifestyle changes, what we monitor, and what to realistically expect month by month.
