The Short Version
This claim dramatically overstates the evidence. While metformin shows some ability to modulate HIV biology in laboratory and animal studies, no clinical evidence supports the assertion that it can enable long-term remission without daily antiretroviral therapy. Multiple peer-reviewed studies actually show metformin can increase HIV transcription and reactivate latent virus. All human studies tested metformin only as an add-on to ART, not as a replacement. The claim conflates early-stage, preclinical findings with established clinical capability.
