Transparent Labs went above and beyond when I accidentally missed my pause on the monthly subscription. Not only did Reilly act with total professionalism, but also refunded me in full and told me to keep and share the product with friends and family. It was so refreshing to have a company understand the mistake and be so forgiving.

I have a subscription that I paused because I was traveling internationally and when I came back home I unpaused and accidentally duplicated my order. I emailed within the day and Colin and Reilly were able to resolve this problem within the day! Not too many places these days have great customer service and great products - will definitely be cautious on next order haha. But nonetheless will be back.

NBP: Nothing But Praise! Their products are undeniably top notch. From the ingredients used to third party testing TL comes through with the highest of marks in my book. So what could possibly be better? We've all experienced frustration with other companies customer service, but TL's customer service is truly the best I've encountered anywhere. This is what a supplement company should be and TL is the out-in-front leader.

I ordered the Stem-Free pre-workout supplement and I had a reaction to it. I contacted the company and they were very helpful with my concerns and even agreed to send out another product that didn’t have the ingredient that caused my reaction. I’m very happy and pleased with the assistance I received from them. I highly recommend this company because they stand behind their products and are committed to making sure that your are satisfied.

After a recent order I checked my email later in the week and TL had sent me a notification that my order had apparently sat for several days in a regional carrier center, I hadn't noticed so it caught me by surprise. This morning the shippers apparently discovered the delay and transferred my order to the local USPS, it was delivered with our mail about noon today. I just wanted to take a moment to commend Transparent Labs for the excellent service you provide from start to finish, keeping track of the shipping status goes beyond my personal experience, you have set a high standard for others to follow, my thanks to all involved from ordering to delivery. On another related note in which I may as well also give you a superior rating, I'm 73 yoa and have been following the YouTube creator Still In The Fight, he is a former Special Forces US Army medic who creates content that is strictly related to health and fitness for seniors. One of his most recent episodes involved a problem he encountered taking creatine, the product he was using (not TL) developed lumps and inconsistency as he was nearing the bottom of the container. I am just now starting my resistance training after finishing my chemo treatments, I opened my current container of TL Creatine HMB and discovered a desiccant pack inside, I recalled the problem the YouTube creator had and thought this was a excellent preventive step to sustain product integrity, though I've not noticed any problems with TL products. A few days later I discovered a second desiccant pack further down in my container, you had doubled the protection of my product! I just want to let you know that again places you on the podium above all products I use, your commitment to excellence is not just talk, you also backup your talk with positive and productive action.
