Top benefits
Week 1–2
Enhanced innate antimicrobial defense. May notice faster resolution of minor infections. Improved wound healing speed.
Week 3–6
Biofilm disruption effects becoming apparent for chronic infections (Lyme, SIBO). Improved immune surveillance. Reduced chronic infection symptoms.
Week 8+
Sustained antimicrobial and immunomodulatory benefits. Chronic biofilm-associated infections may show significant improvement. Enhanced wound healing.

Stacks Well With
Thymosin Alpha-1
28-amino-acid immune peptide from thymus tissue. Strengthens T-cell maturation, boosts natural killer cells, and balances immune response. Tested in 30+ trials, approved in 35+ countries for hepatitis, HIV support, and infections. No serious side effects.
BPC-157
A healing compound from human gastric juice. The most extensively studied repair peptide in animal models, with strong preclinical data for tissue repair, gut restoration, and anti-inflammatory effects. Human clinical data remains limited.
KPV
Three-amino-acid anti-inflammatory peptide especially effective for gut inflammation. Go-to for IBD and inflammatory gut issues. Also calms systemic inflammation.
