Yes – GymBeam publicly publishes a PDF report from the independent laboratory Planton for True Whey, which is tied to the specific product batch and covers microbiological safety as well as the content of heavy metals such as lead, cadmium, and arsenic. This matters, since independent analyses show that roughly half of the protein powders tested on the market exceed safety thresholds for these metals, with chocolate flavors on average more affected than vanilla ones (Clean Label Project, 2025). In this product category, a publicly available, batch-specific report is relatively rare, which is one of the main reasons for the high independent-testing rating given to this product.

Concentrate (WPC) has a slightly lower protein content per gram and more lactose and fat than isolate (WPI), which is why isolate is considered a scientifically somewhat superior form with a higher DIAAS (Herreman et al., 2020). In practice, this means that for the same serving weight, WPC will contain slightly less pure protein and more secondary ingredients. For True Whey this isn't a major issue, since the product still reaches 23 g of protein per 30-gram scoop, which falls within the clinically relevant range for a single meal (Jäger et al., 2017). For people with pronounced lactose intolerance, isolate would still be the more suitable choice.

Whey is absorbed quickly and causes a pronounced but relatively short-lived rise in blood amino acids, making it a convenient choice right after training. However, meta-analyses show that for long-term gains in muscle mass and strength, total daily protein intake (up to a threshold of about 1.6 g/kg of body weight) combined with proper strength training is what matters most, not necessarily the choice of a single protein source (Morton et al., 2018). So this protein won't inherently boost muscle growth more than another quality protein source if your total daily intake is comparable – what's key is hitting your target daily protein intake (Jäger et al., 2017).

Since True Whey is predominantly a whey protein concentrate, it contains a certain amount of lactose, so people with lactose intolerance may tolerate it less well and experience bloating or digestive issues. If you have a diagnosed intolerance, a product based on isolate, which contains less lactose, or a product with added lactase would be a more suitable choice. If your sensitivity is mild, you can carefully try the product in a smaller amount, but with pronounced intolerance or other health issues, consult a doctor or nutritionist before starting.
