No! For these reasons:
- Some products don’t list all of the ingredients on the label.
- Some products have been adulterated with banned substances (that ARE NOT listed on the label) during the manufacturing or packaging process.
- Some products are made from low-grade ingredients obtained from unreliable sources.
All that to say, checking the ingredient list on a label still doesn’t mean you can be sure about what is actually in the product, and you run the risk of testing positive for a prohibited substance!
