44 out of 100

Training Ground PRE Blueberry may help with workout alertness and short-term exercise performance. It is expensive for the creatine, tyrosine and caffeine it provides.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality22

Most ingredient forms are unspecified, making it hard to compare their quality with other workout supplements. Naming beta-alanine alone does not resolve that uncertainty for the rest of the blend.

Ingredient Transparency66

The ingredient amounts are clearly shown, so serving sizes can be compared. Most forms are missing, which makes it harder to check exactly which preparations are included.

Value For Money25

The blend is expensive for several of its key workout ingredients, particularly creatine, tyrosine and caffeine. Value for the remaining ingredients is less certain.

Customer Satisfaction70

Customer ratings are favorable. The small number of ratings limits how broadly they reflect buyers’ experiences.

Product Focus58

The clearest purpose is workout performance and short-term alertness, despite a much wider range of possible uses. Several exercise benefits depend on continued use, and the caffeine amount may cause jitteriness or anxiety.
