Published disputes & incidents

• MESO-Rx (thinksteroids.com) forum member "AnabolicBill" opened a thread titled "Janoshik Analysis - Scammers? How I lost ~$20,000... Cheaters exposed," alleging fraud. Janoshik's own forum account responded, and the original poster subsequently described it as a miscommunication/delay issue, apologized to the community, and asked moderators to close the thread — an allegation raised but not established as fraud.

• Third-party site ChemVerify reports Janoshik disclosed a data breach (attacker access reported "on or around early February 2026") exposing customer contact info, order/invoice records, addresses, test reports, and sample images; states the public verification portal was not disabled and services resumed within about a day, with no evidence of stolen funds or email access. NOT independently corroborated against a primary Janoshik statement or news outlet.

Notes

A widely-repeated claim that founder "Peter Magic" admitted posting false credentials as a "joke" was deliberately EXCLUDED: the only source found rendered just reader comments, not the interview transcript, so it could not be verified. Several low-credibility content-mill domains (e.g. 24-7.is) were found but not cited — unsourced/inflammatory, not corroborated. Janoshik's own about-us page makes no accreditation claim of any kind.
