What to bring: records that a clinician can actually use — a second dataset Replied, post #83 · Clinical › Prescriber conversations · 27 Jul 2026 · 30 likes A second opinion is a normal part of medicine rather than an accusation, and asking how to obtain one is a legitimate question.

Why retatrutide discussion here is more cautious than elsewhere — one year on Replied, post #65 · Compounds › Retatrutide · 15 Jul 2026 · 4 likes If someone has run retatrutide discussion properly I would rather read that than my own reconstruction of it.

Immortal time bias in a claims-database study — one year on Replied, post #23 · Evidence › Study critique · 14 Jul 2026 · 3 likes Adding a small correction to the Immortal time bias summary above rather than a disagreement with it. The substance holds; one of the figures is out by a factor that…
