Checks out. — Legitimate
-

Creatine monohydrate is one of the best-studied and most effective supplements for strength and muscle size gains.
Examine.com creatine monohydrate monograph -
"2.5g per serving is an effective creatine dose"
Clinical maintenance dosing is 3-5 grams a day; this serving is slightly below that range.
-
"Capsules are a convenient way to get your creatine"
Same brand sells creatine powder at roughly a fifth of the per-gram price of these capsules.
Consumer advice
If you just want the performance benefit, generic creatine monohydrate powder (including this same brand's own powder) delivers the identical compound for a fraction of the price per gram. Capsules make sense only if you specifically want portability and don't mind the markup. Consider taking 2 servings (5g) a day rather than just 2 capsules, since 2.5g is below the typical effective daily dose of 3-5g used in most clinical studies.
