Vanilla Bean - Not Quite
Love products. Recently came out with vanilla bean protein. I was excited. Unfortunately, it tastes more like watered down French vanilla. Bummer. Guess I’ll go back to French vanilla. Otherwise, great all around.

A package of mine went missing at USPS, so not the fault of TL directly; however, upon getting in touch with USPS, they said that the sender is responsible for submitting a package claim. I have called TL at their phone number 3 times and left messages over the past 2 weeks that have not been returned. I also have emailed twice and used their website form once, none of which have been returned either. Based on the feedback from everyone else below, I was under the impression that I would have received much more prompt customer service (or any at all). I am extremely disappointed by this, as the products are not cheap and I have spent almost $2000 there over the last 2 years. EDIT 8/6/26: After seeing this review, TL got in touch with me and refunded me the lost shipment and also sent me a $50 gift card to use at TL. I have amended my review to 4 stars for this. However... they gotta check their phone lines because nobody ever answers.

We sincerely apologize. After supporting us for two years, you absolutely deserved a prompt response and should never have had to contact us repeatedly for help. We’d appreciate the opportunity to make this right. I have issued a full refund on your order and a replacement will be sent ASAP! Thank you for your continued support, and we’re truly sorry that we let you down.

I was very impressed by their customer service! I received the wrong product and needed a replacement. I called and email right away, but it was already close of business on a Friday before a holiday weekend. I was not expecting to hear from anyone until the following week. Instead, I heard from an agent the following day on a Saturday and they replacement had already been processed! I am grateful to have had this expedited.

It will helpfull like us if you can ship to UAE. I check with Healf.com but there price more tha double than the product. Please arrange shipment to UAE.

Transparent Labs has been excellent overall, and their customer service truly goes above and beyond. My only feedback is regarding the subscription UI on the app and website. It would be much more user-friendly to allow customers to separate items within subscription groups directly instead of needing to contact support. Additionally, adding a “skip 1 week” option would improve flexibility, since the current minimum is 2 weeks. Aside from those minor inconveniences, the products and overall experience are easily 10/10.

Excellent Customer service with a quick clear response.
P.B
If you don't hire some serious people to deal with your customer services your ratings will keep going down. I asked for a small voucher to try your products, since I am not based in the US and I will have to pay tax duty and high delivery fee, which is more expensive than the actual product but I got ignored. I suggest to sell only in the US since you can not really deliver your services abroad according to other reviews here. I am updating the rating to 4* for your resolution. I will email you when I am ready to order. Thanks

Hi there, We’re truly sorry to hear about your experience and that you felt ignored. That’s never the standard we want to set for customer care. International shipping and duties can definitely add extra cost, and we understand how frustrating that can be. If you could please email us directly at [email protected] with your details, I’d be more than happy to personally provide you with a discount code so you can try our products at a better value. We appreciate your feedback and the chance to make this right. Warm regards, Transparent Labs Team

I’ve been using Transparent Labs for a while now, and the product is top-tier—powerful, clean, and keeps me focused for hours in the gym. Their customer service is excellent—responsive, understanding, and truly helpful when things go wrong. But logistics are a real issue. Orders often arrive late or get lost. On top of that, I regularly have to pay ~€10 upon delivery, which isn’t mentioned at checkout or in the subscription setup. It’s frustrating and feels a bit misleading. • Product: 5/5 • Customer Support: 5/5 • Price & Transparency: 1/5 I’ll keep ordering for the quality, but I really hope they improve the shipping process and pricing clarity.
