Yep, take the gram.
Where did you read the report, on the vendors site?
Id still recomend you stick to a vendor that sells only kratom
While there are many reputable vendors selling ethnos, i dont know many who carry any 'X' extracts.
The 30X you have should not be confused with being 30 times as strong.
It means that (or is supposed to mean) 30 grams of leaf were used to make 1 gram of extract.
Regardless of what they mark it as, 15X 20X 30X, they tend to be at best about 4 times as strong as plain leaf.
If your not comfortable taking the gram then just take half, its up to you.
On an empty stomach you should feel it within 15 minutes.
