When we place an order with Master Supplements, Inc. they are always very helpful and very pleasant to talk to. They are always sending out emails and notifications when there are promotions going on, which is great and we always receive our order in a timely manner.

Perfect! Like Always! Thanks!

Having dealt with this company for over three years I can honestly say they've not only become more expedient with their delivery but also more friendly and helpful! Scott actually called me from home once, when the store was closed. He took my order and placed it himself the next day. His explanation was that he didn't want me to have to wait. That impressed me...... Kudos to Master Supplements!

Price is high but service is excellent
By Kristine Armitage :.
I ordered direct from your company and paid a higher because I thought the product would be shipped in "Cold Pack". It was not and I will not use your product again. There are cheaper products available that are just as good as yours.

Response from Master Supplements, Inc.· Sep 1, 2015
Hi Robert, I am sorry to hear about your displeasure with our products. I do hope that you take the product and give it a chance to work for you regardless of the doubts you are having. We are very proud of the efficacy of our products and the positive results that have been reported for over twelve years. We can provide testing procedures and test results that speak to the products excellent stability, even at accelerated temperatures. We guarantee the potency through the entire shelf regardless of whether or not the product was slightly chilled with a small ice pack for the short amount of time it takes an ice pack to thaw. In actuality, the moisture brought into the packaging can be more detrimental than temperature to the freeze dried bacteria. That being said, if you are unsatisfied, we offer a 30 day money back guarantee. Thank you for your consideration-Jeff Porubcan, President Master Supplements Inc
Sarah is an exceptional employee. Every time I have placed an order or asked questions regarding your products, she is informative & delightful. As my son battles the pesky Lyme Disease, she has calmed my anxiety with her knowledge, competence and her kind demeanor with her soothing voice. When I phoned her a few weeks ago with a complicated question regarding timing, dosing, of your probiotics with his antibiotics, she researched the correct answer & replied back to me with the answer within a short period of time. When a family is experiencing a loved one with this dreaded condition, an understanding voice at the other end of the phone is greatly appreciated. Thanks & kudos to Sarah!
