Excellent thread. Saving this as a reference for future "which testing service" questions. Bottom line for the community: - Both services are legitimate and produce reliable results - Janoshik = established, comprehensive, paid ($120-420) - Finnrick = newer, innovative free program, growing database - Use whichever is accessible to you — the worst testing service is the one you don't use - Cross-reference between services when possible for maximum confidence - Testing anything is infinitely better than testing nothing Stay safe, test smart, and share your results. That's how we protect each other. 🔬
