"Tootsie just received her Mixlab order and she’s so excited for it! Within two hours of ordering it got delivered to the house and its like she knew it was at the door. She absolutely hates taking her medicine but she truly loves her Mixlab box because it’s so informative, quick, easy to order but especially because includes a new toy each time! Thank you Mixlab for always taking care of her! She can’t wait to place her next order now!"

"As Mizu heals from her broken arm, she needs to be given meds 6 times a day! Needless to say, getting that much medication in her has been very difficult. BUT thanks to Mixlab an incredible compounding pharmacy for pets, Mizu has been taking her meds like a champ! And look at the incredible packaging MixlabRx sends our medications in! It came with hand sanitizer, rattie toys and even a cute little note just for Mizu!!! Customer service was wonderful AND delivery is same day and free!!! I cannot recommend this place enough for your furry babies! This is not a sponsored ad. I'm just so in love with this company and the people who work there. Special thank you to Bahar who was Mizu’s pharmacist! Mizu is taking her meds now and that's a miracle!!! ✨💕✨ Go Mizu Go!!! 💪🏼🐭🌟"

"I wish I could give Mixlab ten stars! Their customer service is beyond outstanding. They send a text update to let me know when they've received a prescription from the vet and then another to ask when I would like it delivered - usually the same day! The meds themselves are cleverly packaged in a box with a personal note to my dog, Olive, and a toy for her inside. I wish my prescriptions came this way! (Well, maybe minus the toy.) To top it off, Mixlab texts a few days later to see how Olive is doing. If you're not using this pharmacy for your pet's medications, you are seriously missing out."

"My beloved cat had cancer and needed some specialized medication. I was referred to Mixlab and can’t say enough good things about their pharmacists. Their personal care and human touch made a terrible time a bit better and I will never forget it."

Loki, CA

"Mixlab totally exceeded my expectations!! Silas was in need of antibiotics and a few other meds and they came next morning. When I opened the box, I nearly cried because the little personal touches were so stinking cute. Thank you, Mixlab staff for ensuring Silas got what he needed, and at a fair price at that. I absolutely recommend anyone in need of pet meds to use their service because I know we will continue to do so!"

Silas, PA

"I have to say this is the best pharmacy ever and it has made my life so much easier! It’s literally the best thing ever. They text you to check up on your animal, give you updates and reminders for refills so you never forget. It has saved me multiple times from running out of medication. They go above and beyond to make sure your furry loved one is pampered with a toy delivered with every package. Additionally, deliveries are very fast, the box and instructions are easy to follow and very informative! I 100% recommend this pharmacy to anyone, you wont regret your pharmacy level up!"

"Wally is a fan of the new doggie pharmacy we are using for all of his prescriptions 😍. Mixlab even made a special peanut butter treat out of one of his prescriptions and included hand sanitizer and a personalized note with info about all of the medication 🧼💌🥜👍🏻! Wally approves of the tennis ball they included for him too 🎾🐶❤️!"
