Guttides is a supplement that combines two peptides, KPV and BPC-157, which work together to support gut repair, reduce inflammation, and enhance gut resilience

Once symptoms clear, reintroduce 5-amino-1MQ at half the original dose (e.g., 25mg instead of 50mg daily) and titrate upward slowly over 23 weeks to assess tolerance
