Great Service and received my product… Great Service and received my product within 6 days of ordering it from the company. I was able to track it within 24 hours of ordering. Definitely will order again from this company.

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.

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

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 . . .

They were quick to right an error They were quick to right an error, and issue refund.(I reordered.) I feel fenlab is ethical and responsible. I trust them (you).
