Comparison Centre
Two compounds, the same questions, no cherry-picking
Marketing compares compounds on whichever measure flatters them. This compares them on the same fields every time — including the awkward ones like how much human safety data exists. Every score here rates the evidence, not the compound: a higher number means stronger or more mature research, not that something is safer or works better.
Sharing keeps the two compounds you picked.
How to read these scores
Every number here rates the evidence, not the compound. They are editorial 0-100 strength ratings, not percentages, and not a rating out of five stars.
- Human efficacy evidence strength — Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
- Preclinical evidence strength — Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.
- Human safety evidence strength — Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number. A score of 80 does not mean “80% safe”.
- Evidence level (L0-L5) — the strongest type of study behind the compound, from anecdote (L0) to large replicated human trials (L5). It is a description of the study evidence, not a quality, safety or recommendation rating.
- Confidence — how likely we think it is that this rating changes as new research lands. Low confidence means the picture is unsettled, not that the compound is bad.
None of these ratings is medical advice, a safety guarantee, or a recommendation to use anything. How we grade evidence.
Petrelintide
A long-acting amylin analogue in Phase 2, with Phase 3 weight-management trials planned.
Eloralintide
An investigational selective amylin-pathway agonist now in a broad Phase 3 programme.
How far human research has progressed
Petrelintide
Phase 2 programme reported; Phase 3 initiation plannedEloralintide
Phase 3 programme actively enrolling; published human data limitedHuman efficacy evidence strength
Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
Petrelintide
Eloralintide
Preclinical (animal / lab) evidence strength
Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.
Petrelintide
Eloralintide
Human safety evidence strength
Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number.

Eloralintide
Regulatory status (legal position, not proof it works)
Petrelintide
Not approved anywhere. The sponsor's Phase 2 ZUPREME programme has reported results, and initiation of Phase 3 chronic weight management trials was described as planned for the second half of 2026.Eloralintide
Not approved anywhere. The Phase 3 ENLIGHTEN programme is enrolling across obesity, type 2 diabetes, obstructive sleep apnoea, knee osteoarthritis and people already on incretin therapy.Common claims
Petrelintide
- · Meaningful weight loss with amylin pharmacology alone
- · Better tolerability than incretins
Eloralintide
- · Weight loss without incretin-style gastrointestinal burden
- · Useful added on top of existing incretin therapy

Cancer-related questions raised by the biology
These are theoretical or monitored questions raised by how a compound works. They are not evidence that it causes cancer.
