What is genuinely unknown about long-term amylin agonism Replied, post #86 · Compounds › Cagrilintide & amylin analogues · 25 Jul 2026 · 5 likes On analysis: an amylin analogue and its aggregates are not equally detectable by a standard reversed-phase method, because a large aggregate may not elute at all.

Secretagogues and glucose tolerance: the mechanistic concern Replied, post #65 · Compounds › Secretagogues & GH axis · 7 Jul 2026 · 8 likes Reading a rodent study on a secretagogue without over-extrapolating: rodent studies can show a mechanism is plausible.

Comparing prices across jurisdictions without misleading yourself Replied, post #64 · Access › Pricing · 11 Jun 2026 · 29 likes Building on post #63 rather than restating it. On comparing prices across jurisdictions, the part that usually goes wrong is that the question is asked as though it has…

Prediction intervals and why they are more honest than confidence intervals Replied, post #11 · Evidence › Meta-analyses · 5 Apr 2026 · 0 likes What I want from this prediction intervals thread is the list of things that would need to be true for the claim to hold.
