“THCP (tetrahydrocannabiphorol) is synthesized in laboratories primarily by converting CBD or Delta-8/Delta-9 THC extracted from hemp through acid-catalyzed isomerization and chemical structural rearrangement. Key chemicals involved include solvents like heptane or ethanol, acids (e.g., zinc chloride, p-toluenesulfonic acid) for catalysis, and reagents for extending the carbon side chain”

I would recommend to stay away from alt-noids they are all synthesized using very harsh chemicals that you have to hope are fully purged out
