Not necessarily. This product actually stands out for its formula transparency, as the manufacturer precisely states that whey protein concentrate makes up 91.9% of the composition, with only cocoa powder, one emulsifier, and one sweetener added – which is more transparent than many pricier products in this category, where the main ingredient's quantity isn't specified. It uses whey concentrate instead of isolate, which is the standard rather than the highest-quality form of protein, though milk proteins are generally already considered a high-quality source with a high DIAAS (Herreman et al., 2020).

This means the product passed an independent comparative test conducted by the Slovenian consumer organization, which typically verifies compliance with the declared composition, sensory properties, and in some cases the presence of contaminants. This is an independent but usually one-time comparative test, not a routine, batch-specific laboratory test of every production run, as offered by, for example, NSF Certified for Sport certification (NSF International). Nevertheless, this is one of the few products in this category with a publicly verifiable independent source of information, which is an additional advantage when choosing.

Independent analyses of protein powders on the market show that chocolate flavors are, on average, somewhat more burdened with heavy metals (e.g., lead and cadmium) than vanilla ones, likely due to cocoa, which can naturally contain trace amounts of these elements (Clean Label Project, 2025). This is a general category-level tendency and does not mean that this specific product has exceeded safety thresholds – we don't have an additional publicly available lab report on heavy metals for this product to confirm or refute this. If this concerns you, you can choose the vanilla version or check for additional test results with the seller.

21 g of protein per 30-gram scoop falls within the ISSN's recommended range for stimulating muscle protein synthesis after a meal (roughly 20–40 g, depending on body weight), making it an effective single dose, though it is on the lower end of the range compared to some other products in this category that contain up to 25 g per serving (Jäger et al., 2017). Two doses at once aren't necessarily needed – it's more effective to distribute your protein intake throughout the day according to your overall daily goal, rather than concentrating it in one meal.
