Mr N.
Protein Powder(sour taste)
Been a member receiving my stack for about a year & a half. My issue is with the protein powder, they changed the formula a while back bumping up the protein amount. A slight taste change came with that, all good. But recently my last two deliveries (March 2026) specifically the chai flavor ( only flavor I drink) the flavor is off It’s near rancid just with nut milk or cows milk & I does not mix well with smoothies (taste wise). Their support did send me replacements, I did inform them about the taste & asked if any revisions took place and the rep told me no. But after getting the replacement batch the same off taste was there both packages shared the same lot # 26B2373. I hate it that the rep didn’t ask any other questions about the mishap I believe this may be a QC issue before this March batch I religiously would have 4 scoops of this protein powder daily morning & post workout now it looks like I will have to find another brand. Not to brag but I know how the taste profile should be & something changed hope they can pin down what.

Thank you for taking the time to share this, especially as someone who has supported us for so long and knows the product well. We’re really sorry for the frustration here. We completely understand that receiving replacements from the same lot number would not have been helpful if the issue you were noticing was batch-specific, and we appreciate you calling that out. In an instance like this, a credit would have been more appropriate. We also appreciate your noting that we could have done a better job asking follow-up questions and gathering more detailed feedback during the initial interaction. That’s valuable feedback for our team and something we can improve on. To clarify, we did confirm internally that no formulation revisions were made to this product, and also that your experience and reports regarding this batch have been documented and shared across our support and product quality channels for further review. We truly appreciate both your honesty and your long-term support, and we’re sorry this experience left you disappointed.
