After hearing rumour that Fenben Labs… After hearing rumour that Fenben Labs diluted their product, I had an analysis (NMR and Raman spectroscopy) performed on the powder sample I bought from them. The analyses indeed showed that the product contained only 27% by volume of Fenbendazole. The other 73% was calcium carbonate (essentially a filler). The company should explicitly state this but they lead one to believe they are buying pure product. Dear Fenben Lab Team, Thank you for your response. I will happily share more detailed information with you if you tell me exactly what you need. I was not casting any aspersion on the purity of the Fenbendazole in your products - the analyses showed that the Fenbendazole part of your product was indeed as pure as you claim. This is not the point I was making - the point I was making is that you mix this product (presumably after you have done your own tests with your third-party lab) with calcium carbonate in the proportion of 27% Fenbendazole to 73% calcium carbonate, You are therefore selling your customers a mixture of two powders, meaning that anyone buying your produce will need to take four times the amount to reach the required concentration of Fenbendazole. Perhaps you should send to your independent testing lab a sample of the final product (the one you sell) and see what the result is . . .

Customer service was very helpful Customer service was very helpful, item arrived on time.

Great product, easy to order. Quick delivery. Quick delivery. Easy instructions on use. Nice to have a spoon for dosage. Ordered twice.

My order was delivered and handled… My order was delivered and handled promptly. The Company places a lot of value to detail which is a really nice experience in today’s world. As far as the effectiveness of the product, I will write later as I am still in the process of experiencing it.

Yes, but it was not responsibility of the seller. There was a problem with dispatch because the recepient was not home at the time of selivery. I thought I had lost my purchase. However in just about a week the company sent the product again and free of charge, even though I had not complained. The patient, a brother of mine was under radiotherapy for a squqmos cell carcinoma of the vocal cords, fortunately FenLab produces fenbendazol in powder formulation, and he could start treatment. Nowadays, he is doing well and I shall buy the product again, just for, hopeful, prevention of a relapse.
