Excellent, ethical company My interaction with Fenben Lab has been an all around positive experience. I had a question about the product and Valentina from Customer Service replied to me clearly and in great detail. I ordered the product and it arrived just a few days later with secure packaging. The product appears to be of extremely high quality and comes with an up to date certificate of analysis that shows the purity to be 99.9%. If you are looking for a reliable and trustworthy supplier of Fenbenzadole sold at fair and reasonable prices, I can highly recommend Fenben Lab.

Have only just started buying from… Have only just started buying from Fenben Lab and although I was cautious buying from a company on the other side of the world that I know nothing about, I have been pleasantly surprised. I cannot fault the product or the service. I asked others about Fenben Lab before purchasing and received the same feedback. Well done Fenben👍

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

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