Where's the ingredients? Highly suspicious if they don't show the required complete ingredients list.

the list is on the back of the bottle

Is glucovantage super berberine 3rd party tested for heavy metals contamination?

They are 3rd party tested. Go to Peak Performance's website for further info

third party lab tested?

I don't believe it is. On the bottle, it only has a GMP, Non GMO and Formulated in the USA "certifications". That said, I believe is a good product, my husband is already on his 3rd bottle, and along with a healthy keto diet, he is already out of diabetes and blood pressure meds in 2 months.

Where are the studies citing proof of your claim that this berberine truly is 5x more effective than other berberinen HCL?

Super berberine is 5 times more powerful. Look at the labels and compare.
