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 . . .

I recommend FenBenLab product and service I had a few queries before I ordered and they were answered promptly by email. Once the order was placed, it was dispatched promptly and received in good time considering international posting. Time will tell if the product is effective.

Prompt, well packaged and reliable I’ve ordered from Fenben Labs a few times. Shipping was prompt, the orders were well-packed in sturdy little boxes, and my orders arrived when promised. Given that I’m taking fenbendazole for cancer prevention due to family history, all I can say about the product’s effectiveness is that it hasn’t failed me so far.

Best online resource I've found I researched several online places before choosing FenbenLab for my purchase. Your site is informative and easy to use. We have finished our first 5 day treatment, waited 3 weeks, and just started our next round.

Hello Fenben lab Hello Fenben lab. I just made another buy from you this night buying 180 tablets of fenbendenzol, but I forgot to make use of my 10% Gift Card. I find the tablets very reliant and till now without any side affects. My body is rather sensitive, so therefore I only took half a tablet of 444 mg strength against parasites, and I now realize that this is probably too little against parasites. - (It is a roundworm who has chosen to be my guest) - I do also appreciate that fenbendenzole is effective against cancer even though it is not actual for me now. - Your delivery time was very fine. - But of course it would be even better if the tablets were not so expensive. Kind greetings Birthe Kjærgaard
