1.0 out of 5 stars Not 2000mg
By Tomy Jones on June 29, 2019
These are only 500mg pills.

It says 2,000mg on the title of this product, and on the front of the bottle. Then in little tiny writing, probably illegal (definitely fraudulent), says per serving.

Of course the dosing is 2,000mg. That goes without saying.

Like with Ibuprofen, it’s dosing is 400mg — but the bottle says 200mg, since EACH PILL is only 200mg. I imagine, if this company sold ibuprofen, they would probably put 800mg on the bottle, and simply recommend taking 4 pills.

Not only is this false advertising, and makes it very difficult to compare apples to apples, but it is very unethical.

Just another example of someone cheating the system and cheating customers — for the sole purpose of making money for themselves, at no benefit to any other person in this world. Shameful.
