A few useful questions can make a supplement easier to evaluate.
What is in a full serving?
Read the serving size, ingredient amounts, other ingredients and warnings. Both Charlie’s formulas list 5 g creatine monohydrate per serving. Hydration also lists 1,000 mg sodium, 200 mg potassium and 60 mg magnesium.
What does the evidence actually cover?
Ingredient research, customer experiences and laboratory reports answer different questions. A study on creatine does not by itself verify a finished tub’s contents or guarantee an individual result. A customer review can describe an experience without establishing a health outcome.
Can I verify a quality claim?
For a testing or certification claim, look for the exact product, testing organization, date and scope. For a batch report, check that its lot number matches the product being discussed.
What am I agreeing to buy?
Check quantity, price, shipping, return terms and whether the order renews. If you select a subscription, understand its schedule and how to manage it. Both Charlie’s formulas can be purchased once.
