Don't be fooled by competitors products with "pure" fenben showing false and unverifiable lab results created by their own company. Happy Healing Fenben has been third party independently lab tested to insure quality of 99% pure fenbendazole. Happy Healing is the only trusted source of legitimate 99% fenbendazole on the market.
Fenbendazole is best absorbed when mixed with a few drops of DMSO or oil/fat. Without a solvent it will not be absorbed. Competitors products claiming 99.9% purity are falsely represented.
