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.
Orexin B
A distinct endogenous 28-amino-acid orexin peptide studied mainly in receptor, tissue and animal experiments; no verified human intervention was identified.
Brenipatide
An investigational dual GIP and GLP-1 receptor agonist now in Phase 3 trials for alcohol use disorder and major depressive disorder, with no efficacy results published.
How far human research has progressed
Orexin B
Preclinical (receptor, tissue and animal studies)Brenipatide
Two Phase 3 trials in alcohol use disorder recruiting since October 2025 (estimated primary completion April 2028); no Phase 3 results posted, and no earlier-phase results are established in our curated recordClaim-specific benefit evidence
A human exposure study or trial registration does not establish that the claimed benefit occurs.

Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.

Regulatory status (legal position, not proof it works)
Orexin B
Check jurisdiction-specific details in the profile.
Orexin B itself is not an approved medicine. Evidence for Orexin A, engineered orexin analogues or small-molecule orexin receptor drugs must not be transferred to this peptide.
Brenipatide
Check jurisdiction-specific details in the profile.
Not approved anywhere, for any indication. Brenipatide is not approved for alcohol use disorder, major depressive disorder, diabetes, obesity or any other use. Lilly's public pipeline lists it as a biologic entity in Phase 3 development for alcohol use disorder and major depressive disorder. Registered late-stage trials mean a sponsor is testing a hypothesis formally — they are not a regulatory decision and not evidence that the hypothesis is correct.
Common claims
Orexin B
- · Wakefulness and focus
- · Appetite or metabolism effects

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.
Orexin B
Not established. No specific signal identified in the curated record.Brenipatide
No demonstrated human cancer signal. Precautionary class-level considerations from incretin pharmacology apply and safety surveillance sits inside the ongoing trials.What this adds up to, in plain English
