When it´s tren or other androgens and DAO/anti histamine doesn´t fix it, the only option is to go to cruise/low AAS ro reduce histamine inflamation?If unchecked for long enough it is possible as with excess histamine and irritated mast cells your body and respiratory will be in an inflamed state.
Overall I’d check deeper into your blood work and immune markers though on that one personally. There’s still a root cause under histamine issues- in this case it’s Tren or increased androgens. In other cases it’s eating food high in histamines.
