Verified purchaseThey don’t respond when packages are lost or products are damaged. It’s a numbers game.

Verified purchasePros: Fair pricing (with discount code), good selection of products, COA's included testing for endotoxins and heavy metals (not all suppliers go this far with their COAs), easy to order and pay online, shipping speed was ok. Only con: Shipping packaging in my opinion was mediocre -loose vials in a shipping style envelope (could have broken easily with carrier mishandling) and no real temperature control measures.

Verified purchaseI had a stolen order worth more than $800. The company was VERY generous and sent me a make up order 10 days later. WHERE ELSE DOES CUSTOMER SERVICE LIKE THAT EXIST THESE DAYS? I'm a customer for life. 24 hour customer support, a wide range of quality research compounds & quick turn around times also helped earn my continued business as well. HAVE FedEx hold your package at a local storefront.
Engineered for elite research, our products combine pharmaceutical-grade quality, with rigorous independent testing!
