Pack, dose and cost
Printed potency
No numeric quantity is printed on 10 organism rows of the latest observed label; potency basis Potency is stated through expiry. 10 rows sit inside a proprietary blend, so their individual amounts are not disclosed.
Evidence behind the label
Counts describe records matching each organism's published query, including trials of multi-ingredient products; they are not a count of trials of this product.
