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 . . .

First time customer First time customer. Great customer service and fast shipping. Will purchase from them again when needed.

I like... Easy online ordering. Received order with secure packaging. Appears to be a good quality product, but need more time to evaluate the results.

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

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.
