Essential Information
The Korthals' Standard
Each batch undergoes comprehensive analysis at independent laboratories, testing for alkaloid content, heavy metals, pathogens, and adulterants. We maintain complete transparency with certificates of analysis available for every product.
Understanding Vein Classifications
Red vein varieties are traditionally associated with evening use and relaxation. Green vein selections offer daytime balance and mild invigoration. White vein strains provide morning energy and focus. Yellow varieties undergo specialized curing, while our specialty strains offer unique alkaloid profiles.
