"It's a three-product bundle of creatine monohydrate, beta-alanine (sustained-release), and essential amino acids with BCAAs in lemon flavor."
Bottom line:
Consumer advice
Before buying, contact Thorne directly or check the product label to confirm the exact dose (mg or grams) for each ingredient per serving. Compare this to clinical study doses: beta-alanine should be 4.8-12g/day, creatine 3-5g/day, and EAAs 9-20g/day. If doses are significantly lower, the product may be underdosed. If you're price-sensitive, buying individual products from MyProtein or Optimum Nutrition will save you $30-50 and give you more control over doses. The subscription model is transparent and cancellable, so there's no risk in trying it, but the lack of dose transparency is a red flag that should be addressed before purchase."
