Evidence, context and community
Understand GLP-1 treatments without the sales pitch
Clear, sourced information about Mounjaro, Wegovy and GLP-1 medicines, alongside moderated self-reported experiences that are never presented as clinical evidence.
Information, not a prescription. MERALVIA does not diagnose, prescribe or tell you which treatment to use. Indications and availability vary by country.
Treatment hubs
Start with the medicine, then check the jurisdiction
Mounjaro and Wegovy have different active ingredients, mechanisms and authorised uses. The exact indication depends on the country and current product information.

RatingExperiencesAggregate data
Community experiences
Personal accounts, kept in their proper place
Approved submissions can add context, but they do not establish efficacy, safety frequency or causation.
Every sentiment is treated equally
Positive, negative and neutral accounts follow the same moderation criteria.
Always self-reported
Community information is labelled by origin and never clinically verified by implication.
Separate from evidence
A personal experience cannot replace official information or professional care.

Community data is self-reported, moderated and subject to a minimum sample threshold. It cannot demonstrate that a medicine caused an outcome.

Regulatory and primary material takes priority.
- Sample shown
Published metrics display their denominator.

We do not choose a treatment for the reader.
- Context preserved
Jurisdiction, uncertainty and data origin stay visible.
