GLP-1: peptide pill versus small molecule

Why the most famous oral GLP-1 is not a peptide at all, and what that teaches us.

Most wasted peptide budget is decided at the sequence stage, long before the lab gets involved. This guide is a practical, research-use walkthrough, written for people who have to make a real call about a real sequence.

The short version

Why the most famous oral GLP-1 is not a peptide at all, and what that teaches us. EndoPhase exists to put that judgement at the start of the process, where it is cheapest, and to keep the reasoning on record.

Why it matters in practice

A good decision layer turns a risky guess into a documented, reviewable call. The teams that do this well are not the ones with the biggest models. They are the ones who decide what is worth making before they make it, and who write down why.

Catch the risk while the peptide is still text, not a vial.
Keep the rationale attached, so the next decision starts smarter.
Hand synthesis a clean, documented brief.

Where EndoPhase fits

Score it, document the reasoning, and keep the evidence attached for next time. That is the whole job: a decision layer between an idea and a synthesis order.
