## Before you buy

- The listing is inconsistent about product type, identifying the primary supplement as Vitamin B1 despite presenting it as BCAA powder. Its directions specify 9.5 g per serving while 266 g divided across 28 servings does not match that amount. The listing also gives mixed descriptions of the serving scoop quantity. Check the current tub label and selected listing details before use.

## A good fit for

- People who want a flavoured powdered BCAA drink for training and are comfortable checking serving details against the tub label.
- Vegetarians seeking a supplement listed as vegetarian, while noting the declared soy allergen.

## Less suited to

- Anyone avoiding soy, since the listing declares that it contains soy.
- Buyers who need an unambiguous serving size or a clearly identified primary supplement type without checking the package label.

## Customer feedback

Opinions are mixed on value, drinkability and side effects, including reports of stomach cramps. These are customer perceptions, not proof of an effect. For buyers considering the specified BCAA and electrolyte powder, taste and ease of mixing may matter, while the serving-detail inconsistencies make checking the tub especially relevant.
- Positive themes: Customers describe the taste as pleasant and not overly sweet or artificial.
- Positive themes: Feedback mentions good mixability and perceived workout energy or recovery support.
- Mixed feedback: Opinions differ on value for money and drinkability.
- Mixed feedback: Side-effect reports are mixed, including some customers reporting stomach cramps.
